Wireless innovation has shaped our digital world. From Wi-Fi and Bluetooth to Z-Wave and Thread, we’ve watched protocols emerge to solve distinct connectivity problems. Now, a new technology is stepping in not to connect devices, but to give them spatial intelligence.
Ultra-Wideband (UWB) is quietly transforming how devices understand and interact with their environment. It’s not as flashy as 5G or as familiar as Wi-Fi, but its impact on secure access, real-time location tracking, and automation is profound and increasingly relevant for businesses.
What Is Ultra-Wideband?UWB is a short-range, low-power wireless protocol that transmits data through very short pulses over a wide frequency band, typically 3.1 to 10.6 GHz. Its defining feature is time-of-flight (ToF) measurement, enabling devices to calculate exact distance and direction between each other with centimeter-level accuracy.
Where Bluetooth and Wi-Fi can tell you a device is nearby, UWB can tell you exactly where it is, how far away, and which direction it’s moving in real time.
RTLS 2.0: Why UWB Is a BreakthroughHaving spent years building and enabling Wi-Fi and BLE solutions used in enterprise RTLS deployments, I’ve seen some of their limitations first-hand. These technologies suffer from environmental noise, RF interference, signal distortion from multipath effects, meter-level error margins, and degraded performance in dense or metallic environments.
Ultra-Wideband (UWB) solves these challenges by using precise time-of-flight (ToF) measurements rather than signal strength. This enables centimeter-level positioning accuracy (typically less than 30 cm), low-latency updates suitable for real-time automation, high reliability in cluttered or reflective environments, and energy efficiency suitable for mobile tags and long-duration deployments.
Why UWB Matters: Strategic Pilots Point to Real Business ImpactAcross sectors, a growing number of businesses are no longer just testing UWB; they’re piloting solutions that point to long-term competitive advantage. In corporate campuses, UWB is enabling frictionless, intent-based access control that adapts to hybrid work models and improves security posture.
In healthcare, hospitals are trialing UWB for staff duress alerts, equipment tracking, and patient flow management, solving problems that legacy RTLS couldn’t address with precision. In manufacturing and logistics, early adopters like Siemens and Zebra are leveraging UWB not just for asset tracking but as a foundation for digital twins and automation triggers.
With enterprise infrastructure now supporting UWB through access points from Cisco and Juniper, businesses can deploy it as part of existing network upgrades. Emerging standards like Aliro, FiRa, and the Car Connectivity Consortium are reducing fragmentation, ensuring that today’s pilots evolve into interoperable, scalable deployments.
These pilots aren’t just proving technical feasibility; they’re defining how UWB will power the next generation of access, automation, and location-aware business systems. Today, UWB-based RTLS solutions are being actively adopted in manufacturing, logistics, and healthcare environments by companies like Siemens and Zebra.
These systems provide real-time visibility into the location and movement of assets, materials, and personnel, enabling use cases such as digital twins, workflow optimization, inventory accuracy, and safety enforcement. In hospitals, UWB helps track medical equipment, monitor patient flow, and ensure staff safety. The shift from pilot programs to operational deployments underscores UWB’s growing maturity and proven value across industries.
Enterprise Access Points Now Shipping with UWBEnterprise vendors like Cisco and Juniper have already integrated UWB radios into their commercial access points, enabling high-accuracy indoor location services for asset tracking, automation, and spatial intelligence. These platforms combine high-speed connectivity via Wi-Fi, basic proximity awareness via BLE, and precise spatial awareness via UWB.
This marks a significant shift toward unified enterprise infrastructure that supports both connectivity and advanced location-aware services.
UWB in the Smart Home: Invisible but PowerfulUWB brings the same benefits to smart homes that it’s bringing to factories and offices:
Hands-free presence detection: Lights turn on as you walk in. Doors unlock as you approach from the outside only. Devices respond based on where you are in the room.
Intent-based automation: UWB goes beyond occupancy; it understands movement, direction, and identity.
Secure, frictionless access: No need to pull out a phone or tap a card. UWB verifies your presence and position securely and invisibly.
The Ultra-Wideband (UWB) ecosystem is being shaped by major industry initiatives focused on interoperability, security, and widespread adoption across homes, vehicles, and commercial spaces. Aliro, part of the Connectivity Standards Alliance, is set to launch in 2025, defining secure and interoperable UWB access control for residential, hospitality, and commercial environments, integrating with Matter and other smart home protocols.
The Car Connectivity Consortium (CCC) has developed a Digital Key specification, adopted by automakers like BMW and Hyundai, enabling UWB-based passive vehicle entry and digital key sharing, which is now influencing smart lock and property access solutions.
Meanwhile, the FiRa Consortium develops technical standards and certification programs to ensure UWB remains reliable, secure, and interoperable across access, automation, and tracking applications. FiRa supports both CCC and Aliro profiles under its testing and certification umbrella. Together, these efforts are transforming UWB into a trusted, scalable platform, moving beyond vendor-specific solutions.
At CES 2025, UWB-powered smart locks from brands like Ultraloq and Schlage showcased hands-free auto-unlocking, demonstrating the practical impact of these standards in real-world applications. By aligning technical specifications and fostering ecosystem-wide compatibility, Aliro, CCC, and FiRa are accelerating UWB’s role in smart environments, from homes and cars to commercial spaces, ensuring seamless and secure user experiences.
How UWB Complements, Not Replaces, Other Wireless ProtocolsUWB doesn’t compete with Wi-Fi or Bluetooth; it complements them. Each protocol plays a different role in the connected environment:
Wi-Fi provides high-bandwidth data connectivity, and UWB adds precise indoor positioning to the same access point.
Bluetooth (BLE) excels in device pairing and basic proximity with low power and ubiquity, while UWB provides centimeter-level ranging and directionality.
Thread/Z-Wave supports low-power mesh networking, great for automation, and UWB enables intent-based triggers and presence awareness.
NFC provides secure, intentional tap-based access; UWB enables the same level of security passively and hands-free.
The future is multi-protocol. UWB will often be embedded alongside BLE and Wi-Fi, silently enhancing the intelligence of connected experiences.
Why Consumers Won’t Ask for UWB - And That’s OKUWB isn’t a protocol users will connect to or configure. It’s not trying to be the next Wi-Fi or Bluetooth. Instead, it operates invisibly, delivering context, precision, and automation without user intervention.
We already see this with Apple’s AirTag, which uses Bluetooth for wide-area discovery and UWB for pinpoint precision when the user is nearby. That moment when your iPhone tells you to “turn left” or “go five feet forward” to find your keys? That’s UWB at work, providing directional awareness far beyond what Bluetooth can offer on its own.
Similar features are emerging in Samsung’s SmartTag+ and Google’s Find My Device network, leveraging UWB for object finding, room-level location, and even AR guidance. Yet the average user may not have any idea what UWB is, nor do they need to.
In fact, UWB is already embedded in hundreds of millions of smartphones and tracking tags, from iPhones and Pixel devices to select Galaxy models. Consumers benefit from its capabilities every day, without ever needing to know the acronym.
That’s UWB’s strength: It works quietly in the background, making environments more responsive, secure, and aware, without requiring attention, setup, or even awareness. Think:
- Smart locks that unlock as you approach
- Cars that know it’s you before you touch the door
- Lights that follow your movement room to room
- Devices that guide you to lost items with directional arrows
UWB may never become a consumer buzzword, and that’s exactly how it was designed to succeed.
The Bottom LineUWB is the missing spatial layer in our increasingly intelligent environments. It delivers the precision and context that AI, automation, and access control systems require, but without asking users to do anything differently.
Whether you’re designing smart homes, connected cars, secure campuses, or dynamic retail spaces, UWB won’t be the feature customers ask for. But it will be the reason everything works better.
For forward-looking businesses UWB isn’t optional–It’s foundational.

Artificial intelligence has become a back-office powerhouse and essential resource for sifting through data, optimizing processes, and automating the repetitive. But as AI tools become more accessible, they are no longer just crunching numbers behind the scenes. Executives are increasingly turning to these platforms as a trusted advisor for providing strategic insight and informing business decisions.
Our recent survey found that nearly three-quarters (74%) of executives trust AI’s input over that of friends or colleagues. Even more striking, 44% said they would allow generative AI to override a decision they had already planned to make. These findings mark a profound shift in how leadership decisions are made.
Traditionally, executives have relied on a blend of data, gut instinct, and conversations with trusted advisors. Now, AI is earning a spot in the inner circle, signaling a fundamental redefinition of how leaders pair human insight with machine intelligence to drive better outcomes.
AI as Strategic Co-PilotAs companies prepare for an AI-focused future, business operations are being rewritten. Companies in every industry are looking for ways to incorporate AI that can help them build even the smallest competitive advantage. As a result, AI is taking on a new role as the C-suite’s strategic copilot, handling tasks like data analysis and recommendations (52%), uncovering hidden risks (48%) and presenting alternate strategic paths (47%).
AI is helping leaders go deeper—to challenge assumptions, test new scenarios, and make more informed decisions about how their business operates. But even in everyday life, AI is finding valuable and exciting uses, with some guardrails.
I’ve used it to help plan family vacations and generate personalized bedtime stories for my children. While it struggles to manage complex scheduling (and the nuances of how I manage my calendar), AI has transformed how I approach and solve many problems, offering a helpful sounding board for tasks in both my personal and professional life.
SAP CEO Christian Klein recently shared that he uses generative AI to preview quarterly earnings results and better understand company performance.
AI’s influence extends to other roles in the C-suite as well, from automated anomaly detection in financial transactions for CFOs, to streamlining contract reviews and generation of new contracts for CPOs, to COOs needing to evaluate capacity planning and manage variability in market demand.
And, of course, there is always the most common use case of all – summarizing complex documents and topics, and generating subsequent action items.
We’re far from alone. More leaders are beginning to incorporate AI into the highest levels of planning and forecasting.
Critical Thinking and the Human TouchAs AI’s influence in the boardroom grows, so does the trust leaders place in it. Part of this stems from AI’s growing ability to analyze massive volumes of data and provide contextually rich insights. In some situations, AI is usurping the guidance of near and dear advisors as previously mentioned. A trusted colleague might offer valuable perspective, but they haven’t parsed two billion data points before weighing in.
Still, there are limits. While executives should continue to use AI to help with business matters, there’s a risk that critical thinking will be lost rather than enhanced as a result. True strategic decision-making will always require a human touch—which AI can't replicate.
Going forward, executives must strike a careful balance, keeping people involved to help make complicated and high-value strategic decisions, while using AI to enhance their thinking, not replace it.
Building a Foundation for Strategic AI UseSuch heightened reliance on AI will also force organizations to grapple with foundational challenges. The reality is that many companies still lack the reliable data infrastructure needed to support high-trust AI use. Lack of alignment between IT and business teams, patchy system integration and concerns about data quality all threaten to undermine the effectiveness of AI as a strategic advisor.
Companies must establish clear guardrails, like those below, to ensure these tools are used reliably and responsibly, balancing speed and scale with transparency and human input.
As AI becomes a true collaborator in the boardroom, the goal isn’t to hand over control. It’s to elevate leadership. In this new era, great leaders won’t always have the right answer, but they will know when and how to ask the right questions—and where to turn for the best insights.
Going forward, we see leadership evolving from command-and-control to co-creation. Those who thrive will be the ones who understand how to blend human experience, emotional intelligence, and machine-derived insight into a cohesive and future-first strategy.
With AI as a loyal advisor, the possibilities for transformative leadership are just beginning.

Australian leader Anthony Albanese accused Iran of organizing two antisemitic attacks in Australia, saying the country would cut off diplomatic relations with Tehran. Iran had no immediate reaction.

When Target decided to enter the Canadian market in 2013, it envisioned a rapid rollout of over 100 stores within two years, supported by a highly automated and sophisticated supply chain system. The strategy looked promising on paper, but the execution was rushed, and the technology behind inventory management and distribution was not properly tested or adapted to the new market.
Stores opened with empty shelves despite warehouses being full of stock, due to systemic data and process errors. The technology-driven supply chain was too rigid and failed to handle the operational realities of a new market and diverse product ranges. Within two years, Target Canada posted losses of over $2 billion and eventually shut down all its stores—a cautionary tale of prioritizing aggressive technology-led execution over a solid, adaptable strategy.
It often seems that organizations are too interested in the new high-tech gear, rather than the root of operations, asking themselves: cloud first? Cyber first? It can be easy to get carried away with the new features and functionalities of a shiny new AI or automation tool.
Without a clear understanding of the underlying problem, even advanced tools become ineffective, leading to wasted investments, poor adoption, and unmet expectations. Businesses need to step back, rethink purchasing decisions, define their wants and, understand the benefits of implementing such tools before making any hefty decisions that will end in a costly write off.
Think value, not hypeOut of all the heralded technology innovations in the last few years, AI has taken the spotlight. Generative tools, such as ChatGPT, have offered instant access to useful information, provided time-saving efficiencies for employees, and allowed tasks to be streamlined. However, this is only the case for companies that use generative AI tools regularly and in the right places.
A survey in 2024 found that only 2% of British respondents actually used generative AI tools on a daily basis - a contrast to the vast number of businesses that are signing up to use this technology. Organizations need to remember that technology without a purpose is a wasted cost that adds to the increasing financial pressures that many businesses are already feeling.
AI hasn’t been the only trend embraced in the last few years. The cloud is a further case in point where the problem-solving capability of the solution often hasn’t been considered. Initially, it is seen as a way to reduce costs though many organizations have been surprised by spiraling costs and integration headaches.
So, rather than following the mindset of ‘cloud-first’, the question should be: “Does cloud benefit my strategy?” Maybe only certain workflows benefit from moving to the cloud or, potentially, the service needs to be used just on certain days. Using the technology selectively and scaling down when it is not required, is part of the strategy that needs to be established to ensure that an organization stays cost-efficient, ensuring real value is gained.
Stakeholders are your best friendsHow do businesses pivot to an outcomes-focused strategy? Too often, isolated departments and IT teams deploy technologies based on tech-first mandates with little input from those who will actually use them day-to-day. A shift in perspective is critically important. Organizations should engage key stakeholders closest to the pain points early in the process, allowing their insights to shape the strategy and identify effective, problem-solving tools.
There is a common misconception that successfully transforming an organization's IT infrastructure means rushing into expensive deployments and buying the latest technology or chasing the newest trend cycle. However, just a more selective approach to automation and AI can extend the value of existing infrastructure to suit organizational goals.
From shiny tech to strategic outcomesIt’s easy to be mesmerized by digital transformations or to believe that what your organization is missing is AI automation. But success will rarely start with the tool.
A great deal can be learnt from Target: involve end users in planning stages and don’t be fooled by the hype. Remember, problem first, product second.
Outcomes need to be placed at the heart of every business strategy that way organizations can unlock far more value from the tools they already have, while making smarter, more deliberate decisions about what to adopt next. This might mean refining the use of cloud services or using automation to achieve efficiencies in areas where it makes a measurable difference
Starting with the obstacle and not the tech ensures that the outcome is a more efficient, cost-effective and sustainable approach to digital transformation.
Tech is just the tool. Strategy is the solution.

The interconnectedness of our digital world brings a wealth of benefits, including the ability to conduct tasks that were once manual with greater speed and convenience. At the same time, society faces an ever-expanding set of dangers, both personally and professionally, on a daily basis. For business executives in particular, the continually evolving threat landscape is now one where the lines between personal and professional, as well as digital and physical, are increasingly blurred.
The latest findings from the Ponemon Institute underscore this new reality. Based on a survey of nearly 600 U.S. security professionals, Ponemon’s new 2025 Digital Executive Protection Report shows a notable increase in attacks targeting business leaders, with survey respondents reporting a rise from 43% in 2023 to 51% in 2025. A combination of factors is driving this trend: executives’ expansive digital footprints, combined with unmonitored and insecure home networks and personal devices, which are often used for work purposes.
The Report also highlights a general lack of cybersecurity training and preparedness among companies to prevent such attacks. As a result, corporate executives are caught in a perfect storm, rich with opportunities for cybercriminals to cause financial and reputational harm – to leaders, their families, and their companies.
The Escalating Risk of DeepfakesWhen examining the types of attacks targeting executives that cause the most harm, the Ponemon findings reveal an increase in deepfake impersonation attacks, from 34% of respondents reporting an incident in 2023 to 41% in 2025. Deepfakes are artificial images or videos created by AI, trained on a collection of authentic media samples of the individual being targeted, including still images, videos, and audio clips, all of which are easily found online. The more samples used, the more authentic the deepfake can appear to be.
Given their highly visible public profiles and prolific social media activity, business executives, high-net-worth individuals, and their family members are easy targets. According to the Ponemon survey, the most common deepfakes experienced are impersonation of executives’ trusted entities and urgent demands for payments or information about a detected security breach.
Of those targeted, 28% reported being impersonated by a trusted entity, such as a colleague, executive, family member, or known organization; 21% stated that executives and board members received urgent messages, including demands for immediate payment or information about a detected security breach.
Additionally, 42% of respondents stated that their organizations’ executives and board members have been targeted an average of three times by a fake image, while 66% of respondents indicated that it is highly likely their executives will be targeted by a deepfake in the future.
Survey respondents disclosed that the financial toll of deepfakes is neither known nor measured. However, most respondents cited the cost of staff time spent responding to attacks and the expense of detecting, identifying, and remedying the breach as the most serious financial consequences stemming from such attacks.
Why are deepfakes on the rise?There are multiple reasons for the increasing number of deepfake attacks. First, the barrier to creating sophisticated and convincing deepfakes continues to drop, given easy access to AI tools and other technologies that power social engineering attacks. According to the Ponemon report, visibility challenges also make it difficult to detect attack tactics, such as deepfakes; half of the respondents stated that their team lacked the necessary insight to prevent a breach.
The report’s findings align with my team’s daily observations on the front lines: the threat landscape is rapidly evolving and expanding, putting a bullseye on the backs of high-profile, high-value executives for both cyber and physical attacks. Over the past few years, we have witnessed an acceleration of sophisticated tactics, such as deepfakes and impersonation scams, that directly target these leaders in their personal digital lives. Hackers understand that executives' personal devices and home networks can be an easy pathway to penetrating corporate defenses.
Securing the company network and infrastructure is critical, but it still leaves gaps. Protecting the organization’s leaders — and their families — is essential to reducing corporate risk, making Digital Executive Protection a non-negotiable security imperative.
How can organizations prevent future incidents?A multi-faceted, holistic approach that focuses on both robust long-term prevention and immediate damage mitigation is required.
I strongly recommend a prevention strategy that encompasses comprehensive defense in depth, including implementing robust email security protocols, establishing strong multi-factor authentication (MFA) across all accounts, and deploying secure password managers, along with continuous monitoring of home networks and devices.
Key to this approach is minimizing executives’ digital footprints, proactively monitoring their personal devices and home networks for threats, and educating them and their families on best practices for online safety.
In the aftermath of any attack – whether a deepfake impersonation leading to fraud or a sophisticated phishing attempt – critical steps should be taken swiftly, such as conducting data broker removal, initiating credit freezes, disputing fraudulent charges with financial institutions, and securing compromised accounts to prevent further financial loss or data exfiltration.
To adequately secure individuals against today's – and tomorrow’s – sophisticated cyber threats, extending comprehensive privacy and cybersecurity far beyond the corporate perimeter is critical. Digital Executive Protection is necessary to safeguard leaders and their families across every facet of their connected lives – from their personal smart devices and online accounts to entire home networks and smart home technology.
The rising tide of deepfake attacks, as revealed by the Ponemon Report, underscores a critical shift in the cybersecurity landscape: executives are now prime targets, their digital lives serving as a vulnerable gateway to enterprise compromise. This escalating threat, fueled by easily accessible AI and a widespread lack of comprehensive personal security training, demands a holistic and proactive approach.
Organizations must extend robust digital executive protection to their leaders and their families, encompassing everything from digital footprint reduction and device hardening to advanced threat monitoring and rapid incident response, giving them peace of mind that they are safe from escalating cyber and physical threats.

Nick Park’s Wallace and Gromit were brought crashing into the 21st century in December 2024 with their latest adventure, Vengeance Most Fowl. The film challenges our growing dependence on smart technology in the form of a robotic garden gnome, built by Wallace to support his gardening business, which is then hacked by the Kubrick-esque Feathers McGraw for his own nefarious purposes.
One of the more interesting but less commented on parts of the film shows Gromit cautiously entering his house and being greeted by what he thinks is Wallace’s reassuring voice, only to be confronted with Feathers and the robotic gnome.
Technology’s ability to mimic linguistic patterns, to clone a person’s voice and understand and respond to questions has developed dramatically in the last few years.
This has not gone unnoticed by the world’s criminals and scammers, with the result that social engineering attacks are not only on the rise but are more sophisticated and targeted than ever.
What are social engineering attacks?Cybercriminal social engineering manipulates a target by creating a false narrative that exploits the victim’s vulnerability (whether that is their willingness to trust people, their financial worries or their emotional insecurity). The result is that the victim unwittingly but willingly hands over money and/or information to the perpetrator.
Most social engineering scams consist of the following stages: (1) making connection with the victim (“the means”), (2) building a false narrative (usually with a sense of urgency or time limitation) (“the lie”) and (3) persuading the target to take the suggested action (e.g. transferring money or providing personal details) (“the ask”).
Usually, stage 2 (the lie) is where most people spot the scam for what it is, as it is difficult to build and sustain a convincing narrative without messing up eventually. We have all received text messages, emails or social media messages from people purporting to be our friends, long-lost relations in countries we have never been to, or our banks, asking us to provide them with personal information, passwords or money.
Historically, such communications were easy to spot, as they bore the hallmarks of a scam: generic greetings and signatures, spelling mistakes, poor or unusual grammar and syntax, inconsistent formatting or suspicious addresses.
Liar, liar, pants on…f-AI-re?However, the rapid sophistication of generative AI tools means that it is increasingly easy for criminals to craft and sustain plausible false narratives to ensnare their victims; the “lie” or stage 2 in the social engineering scam. Companies and law enforcement agencies are scrambling to stay ahead of the technological advances and are working hard to predict developments which will be used for social engineering.
One potential use case for generative AI in this area is a dynamic lie system, which would automatically contact and interact with potential victims to earn their trust before moving to stage 3 (the ask). This would be particularly useful for “advance-fee” or “419” scams. These scams work by promising the victim a large share in a huge amount of money in return for a small upfront payment, which the fraudster claims will be used to obtain the large sum.
The AI-based dynamic lie system could automate the first wave of scam emails to discern whether the potential victims are likely to ‘take the bait’. Once the system identifies an engaged individual who appears persuaded by the communication , it can then pass the control to the human operator to finish the job.
Another development which has already gained traction is the use of AI to clone human speech and audio to carry out advanced types of voice phishing attacks, known as “vishing”. In the United States, the Federal Trade Commission has warned about scammers using AI voice cloning technology to impersonate family members and con victims into transferring money on the pretext of a family emergency.
Current technologies allow voices to be cloned in a matter of seconds, and there is no doubt that with advancements in deep learning, these tools will only become more sophisticated. It would appear this form of social engineering is here to stay.
Do androids dream of electric scams?“If there’s one job that generative AI can’t steal, it’s con artist.” So said Stephanie Carruthers, Global Lead of Cyber Range and Chief People Hacker at IBM in 2022. Fast forward 3 years and Carruthers has changed her position. Our concerns about AI are not just limited to the impact on the workforce but have now expanded to include AI-based bots which can craft tailored social engineering attacks to specific targets. As Carruthers notes, “with very few prompts, an AI model can write a phishing message meant just for me. That’s terrifying.”
Currently AI is being used by threat actors as an office intern or trainee to speed up completing the basic tasks required to carry out social engineering attacks. Carruthers and team did some experiments and found that generative AI can write an effective phishing email in five minutes. For a team of humans to write a comparable message, it takes about 16 hours, with deep research on targets accounting for much of that time.
Furthermore, generative AI can churn out more and more tailored attacks without needing a break, and crucially, without a conscience. Philip K. Dick noted that for his human protagonist, Rick Deckard, “owning and maintaining a fraud had a way of gradually demoralizing one”, but in an increasingly digital criminal underworld, maintaining a fraud has never been easier.

As you can probably tell from my Onyx Boox Go Color 7 review, I didn’t take a shine to the original model released in 2024, which meant I had higher expectations from its successor.
The Boox Go Color 7 Gen II launched in April 2025 alongside a monochrome edition called the Boox Go 7, both sharing the same design and and feature set – the only difference being the screen: the former uses the color E Ink Kaleido 3 display while the latter is the grayscale E Ink Carta 1300.
Physically, both the 2025 Go Series siblings are nearly identical to the Go Color 7 from 2024, with one tiny design change that I’m pleased with – the page-turn buttons on the new models are smaller, rounded and separated a little to improve ergonomics.
On paper, the Go Color 7 Gen II is the better device compared to its predecessor, running Android 13 (rather than Android 12), getting a generation newer processor and adding writing capabilities that the previous model lacked. Like many smaller-screen epaper tablets like it, you will need to purchase the stylus separately, although at the time of writing, the only pen that works with the Go Color 7 II – the Boox InkSense – has been discontinued and no official replacement has been made available.
According to Boox, it’s preparing a new stylus after taking on user feedback, and the new pen “is expected to be available in the third quarter” of this year. Reimagining a stylus is admirable, but it still begs the question: why release ereaders with stylus support (this affects the monochrome Boox Go 7 as well) if their only pen isn’t available to buy?
When I started testing the device about 11 weeks ago, third-party retailers still had stock of the InkSense, which is how I was able to source one for this review, but even those are no longer available. That said, I’m glad the pen is being replaced as I didn’t enjoy the writing experience with a hard nib on a very smooth screen. I’ll update this review when the promised stylus is released.
The 2025 Boox Go series ereaders get writing capabilities but, at the time of publication, the compatible stylus has been discontinued (Image credit: Sharmishta Sarkar / TechRadar)While I’m not docking any points for the lack of a supported stylus at the time of publication, I’m disappointed to see that the 7-inch color screen on the Gen II isn’t as nice to read on as its predecessor. Text on the Gen II is 'fuzzy', for the lack of a better word. Compared to its predecessor, its monochrome Go 7 sibling and the Kobo Libra Colour, text within ebooks and speech bubbles clearly lacks crispness. You can still read, that's not the issue, but it's hard to recommend an ereader when others do a better job.
And while some colors are more saturated here than on the older model and the Kobo Libra Colour, the additional contrast means small details are lost in the darker areas. Strangely, though, the color 'inks' when writing lack this same saturation and look washed out compared to what I've experienced on older color Boox models like the Onyx Boox Tab Mini C.
Boox has somehow managed to make the display yellower (or warmer) than on any of its other tablets, and it's a stark difference between the Gen II's monochrome sibling as well. This warmth sadly affects the displayed colors as well. The yellowness is exacerbated when the frontlight is switched on, giving comics and graphics novels what I call the 'jaundiced look'. In fact, the frontlight isn't even as bright on the Gen II as other Boox ereaders (or even Kobos and Kindles).
The overall user experience is also marred by constant ghosting. It’s not as obvious as I’ve seen in older Boox devices, but it is distracting enough to be an issue. Setting the device to higher refresh rates, however, eats into the battery life, which also drains at a faster rate than other ereaders. Even the preset refresh modes that can be set on a per-app basis weren’t well optimized here, causing excessive stuttering while scrolling on the native web browser.
The good news is that the software issues I’ve had with the previous generation have been fixed and I was thrilled to see that wired transfer via OTG (directly plugging an external hard drive or portable SSD to the USB-C port) works smoothly – something I’ve had problems with in previous Boox tablets I’ve tested. Even the fonts folder within Storage is correctly bound, so things work a little more smoothly now, although the user interface continues to be slightly complicated.
Better implementation of the software doesn’t make up for the subpar reading experience, and neither does selling it at the same price as its predecessor – in fact, I'd say it’s hard to recommend at any price.
The magnetic case made specifically for the 2025 Boox Go series comes with a loop to secure the supported stylus (Image credit: Sharmishta Sarkar / TechRadar)Onyx Boox Go Color 7 Gen II review: Price & availabilityAs alluded to earlier, the Boox Go Color 7 Gen II was announced alongside the monochrome Boox Go 7, both becoming available at the end of April 2025.
Despite the added note-taking functionality, the Boox Go Color 7 Gen II carries a similar price tag to its predecessor (which is already listed as out of stock on the Boox Shop, indicating it might get discontinued soon). Where the older model had a launch price of $249.99 / €279.99 (about £245) / AU$459, the Gen II is listed for $279.99 / €279.99 / AU$439 at the time of writing. As you can see, only US customers face a slightly higher charge likely due to tariffs on several imports. This price includes a magnetic case that features a loop to secure a stylus.
In comparison, the Kobo Libra Colour is cheaper at $229.99 / £209.99 / AU$379.95 for the standalone ereader, but you will need to add on the $69.99 / £69.99 / AU$119.95 for the Kobo Stylus 2 if you want to use it for writing notes, and you’ll need to purchase a case separately if you want one.
The only compatible stylus for the 2025 Go series was the Boox InkSense, which has been listed as “out of stock” since the release of the Go Color 7 II (and its monochrome sibling), and at the time of writing is no longer available from third-party retailers either. I have official confirmation that the pen has been discontinued, and while the Boox Shop lists a bundle that includes the stylus, I’d recommend holding off purchasing the full package until the replacement pen has been released. There’s no confirmed release date at the time of publishing this review, and neither is there any indication of how much the stylus would cost. I’ll update this article as soon as I know more.
Given my subpar experience with the Go Color 7 Gen II, I think the monochrome Boox Go 7 would be the better buy and it retails for $249.99 / €249.99 / AU$399, a price that includes an identical magnetic case as well.

Onyx Boox Go Color 7 Gen II review: Design & displayAs the old adage goes: if it ain’t broke… The original Go Color 7 was a lovely compact ereader that I liked the design of, except for the closely placed page-turn buttons. That's been changed on the Gen II model, which now sports smaller, rounded buttons with some space in between.
This tiny change, in my opinion, makes the Gen II a touch more ergonomic in use, but there’s a case to be made for the asymmetric design of the Kobo Libra series (and the Kindle Oasis models) – it provides a nice resting place for the thumb along the edge of the broader bezel. The slim and flat form factor of the Go Color 7 II can be harder on the fingers and wrists in comparison, although the added thickness from its magnetic case helps a alleviate the soreness a little.
As before, the page-turn buttons automatically become volume controls for apps that don’t require scrolling or page turning, and this functionality can be set on a per-app basis in the Settings menu.
Image 1 of 3The page-turn buttons have been redesigned to being separated and rounded... (Image credit: Sharmishta Sarkar / TechRadar)Image 2 of 3..compared to the straight-edged, closely packed ones on the 2024 Go Color 7 (left) (Image credit: Sharmishta Sarkar / TechRadar)Image 3 of 3The rounded and separated buttons are nicer to use on the Gen II (Image credit: Sharmishta Sarkar / TechRadar)Where the buttons on the older model were a different color to the rest of the chassis (silver on the white colorway and dark grey on the black), the Gen II – and its monochrome sibling – are a single color, available in black (as reviewed here) or white. The one-color look without any trimmings or accents makes the device look a little dated, but that’s not a complaint, merely an observation made in comparison to the older model.
All other physical attributes are identical to the Gen I model, including the textured rear panel which, to me now seems just a smidge rougher that makes the Gen II a little grippier if you prefer not to use its magnetic case. In terms of dimensions and weight, nothing has changed since 2024 and that’s not a bad thing as the Go Color 7 II is compact and lightweight, making it quite portable.
There’s a tiny power button on the bottom right corner of the device, while the right edge is home to the USB-C port, the speaker grilles and a microSD card tray. Only the mic has moved, now housed on the opposite edge.
Image 1 of 2On paper, the Go Color 7 Gen II (top) is the better ereader than its predecessor (bottom) (Image credit: Sharmishta Sarkar / TechRadar)Image 2 of 2The page-turn buttons are the most obvious design change, but the mic is gone from beside the speaker grille to the opposite edge (Image credit: Sharmishta Sarkar / TechRadar)What it lacks is waterproofing; there’s no IP rating for it listed on the official website, so if you plan to travel with it – it's the perfect compact size for doing so – steer clear of the pool.
As I mentioned earlier in this review, the Go Color 7 II uses a 7-inch E Ink Kaleido 3 display, the same as the previous generation, although Onyx has made the newer model more naturally yellow in comparison. This has the unfortunate effect of adding a yellow hue to all the colors on screen, giving them what I call the 'jaundiced look'.
This is exacerbated by the frontlight on the Gen II as it enhances the yellowness of the display. It’s also, rather strangely, not as bright as the Gen I model which, at the time of testing it in 2024, I said wasn’t bright compared to the even older Onyx Boox Page. In fact, the light on the Go Color 7 Gen II is dimmer than its own 2025 sibling, the Boox Go 7.
I had complained about the lack of sharpness on the Go Color 7 (Gen I) when compared to the Kobo Libra Colour, but Boox has managed to make that a lot worse on the Gen II, and that is its biggest failing – a subpar display (more on this below in the User Experience section).
• Design & display score: 3 / 5
The Boox InkSense stylus still works with the Boox Go Color 7 II, but there's no word on what its replacement will be like (Image credit: Sharmishta Sarkar / TechRadar)Onyx Boox Go Color 7 Gen II review: Android software & appsWhere the older model from 2024 was running Android 12, the Go Color 7 II has been upgraded to a custom version of Android 13. There’s usually no need to worry about a device like an ereader running an older version of Google’s OS as there typically aren’t any security issues here, and I doubt anyone would save sensitive information on a device like this.
The trimmed-down version of Android on the Go Color 7 Gen II caters specifically to reading and writing, and should be familiar to anyone who has used a Boox tablet before. If not, the user interface will take some getting used to as it’s not the most streamlined UX I’ve come across. For a simpler setup, you’ll need to turn to a Kindle or a Kobo ereader.
Image 1 of 3The navigation menu doesn't have the Notes tab by default and finding it requires some online research (Image credit: Sharmishta Sarkar / TechRadar)Image 2 of 3Third-party app downloads via the Google Play Store are quick and easy (Image credit: Sharmishta Sarkar / TechRadar)Image 3 of 3The Boox user interface has evolved a little, but it still takes a while to get a handle on as a first-time user (Image credit: Sharmishta Sarkar / TechRadar)The home screen, once you’ve connected to Wi-Fi, is easy to get around, with a navigation menu at the bottom of the display. This gives you quick access to your library, the storage menu and your apps, plus it’s customizable via the device’s Settings menu. There’s space here for five options and, strangely for an ereader with writing capabilities, the native Notes app is not one of them.
Finding it wasn’t easy, but Boox at least has a quick guide online on how to access it: you’ll need to navigate to Settings > System Display > Homescreen Navigation Bar where It’s listed as one of the options for the aforementioned customization. This may not seem like a big issue, but my expectation from a device like this is to highlight its main features up front rather than tuck them away, highlighting the unintuitive UX. In my case, I swapped out the Bookstore as it’s not as enticing a source of content as the Kindle or Kobo stores.
Preset refresh modes are nice to have, but they didn't work as well I had hoped on the Go Color 7 II (Image credit: Sharmishta Sarkar / TechRadar)Given its open Android ecosystem, the interface on the Boox Go 7 II includes a lot of advanced settings that help you use third-party apps as smoothly as possible, but submenus for native applications are difficult to find. For example, you need to open an ebook in the NeoReader app (the native library), tap onscreen to open the top menu bar, click on More, then select Settings from there – another example of a convoluted interface.
Thankfully adjusting fonts and overall styling for individual books is easier to do, but there’s a lot going on here compared to what you’d see on a Kindle or Kobo. The setup for styling, however, is now improved, which makes it easier to understand than previous iterations of Boox’s interface.
In fact, there’s another improvement to the software that I’ve previously had trouble with on Boox devices – taking advantage of the USB-C port’s OTG support for wired file transfer. Previously, the menu required to copy files across from an external hard drive to a Boox tablet would disappear as soon as I tried to navigate back to the Storage pane, thus not letting me add files to the default Books folder. Now that is no longer an issue and I was able to select multiple ebooks saved on my Samsung T7 portable SSD and save into the Go Color 7 II without any issues.
I was thrilled to see that OTG transfer worked a charm on the Boox Go Color 7 Gen II (Image credit: Sharmishta Sarkar / TechRadar)I had no trouble downloading third-party Android apps to the Go Color 7 II. These included the Kindle and Kobo apps as the bulk of my library is on these two platforms, plus an app called CPU X that detects the exact chipset a device is using. I didn’t try any third-party note-taking applications as I’ve always found Boox’s native Notes app to be full featured and more than enough for my needs.
• Software score: 3.5 / 5
Onyx Boox Go Color 7 Gen II review: User experienceAn unintuitive user interface aside, the Go Color 7 Gen II is quite usable. It’s when you compare it to other models, including its own predecessor and its 2025 monochrome sibling that you begin to realize there are better color ereaders to spend your money on. And that’s exactly what my job, as the reviewer, entails – doing the side-by-side comparisons so you, dear reader, can make the most informed buying decision.
As you will see in the comparison photos below, the Go Color 7 Gen II doesn’t hold up well as an ereader. As for writing, it’s hard to rate the experience when you can’t purchase a compatible stylus yet.
There are quite a few submenus to explore on a Boox device (Image credit: Sharmishta Sarkar / TechRadar)ReadingI’ve tested several ereaders in the last eight years and I don’t think I’ve ever been as disappointed with the reading experience as I was with the Go Color 7 Gen II. Admittedly that’s because I’m comparing it directly to a few of its contemporaries, but even if you didn’t do a side-by-side comparison, it’s easy for anyone who’s used an ereader before to say the display looks hazy. I suspect that’s because of the anti-glare layer on the screen, and it’s just a lot more pronounced here when compared to other brands and Boox models.
Colors appear saturated on the Boox Go Color 7 Gen II, but the higher contrast hides details (Image credit: Sharmishta Sarkar / TechRadar)The 7-inch E Ink Kaleido 3 display used here is naturally more yellow than other ereader I’ve previously tested and found this affected how colors appear on screen. I compared it to its predecessor and the Kobo Libra Colour, both of which have paler backgrounds in light mode and made the displayed colors appear as close to natural as is possible on an epaper screen. While I can't say this alone affects the reading experience, I found the monochrome Boox Go 7 was nicer to read on in light mode because of the whiter background – it added a touch more contrast to the page.
The frontlight, which isn’t as bright as I’ve seen previously on other Boox tablets (even the Go 7 that released alongside this ereader is brighter), exacerbates the ‘jaundiced look’. Boox doesn't list how many amber LEDs are used on the Go Color 7 II, but the frontlight is warmer compared to five other ereaders I had with me at the time of this review (two other Boox tablets, two Kindles and a Kobo), which makes the screen look yellower when switched on. The only other E Ink tablet that surpasses the Gen II's warm display and light is the Kobo Elipsa 2E, but here it's not a problem as the epaper tablet doesn't display color.
Image 1 of 2The frontlight of the Boox Go 7 Gen II (left) makes the screen yellower than on the Gen I model (right) (Image credit: Sharmishta Sarkar / TechRadar)Image 2 of 2Even the Boox Go 7 (right) that launched alongside the Go Color 7 Gen II (left) is clearer and brighter with the frontlight at full bore (Image credit: Sharmishta Sarkar / TechRadar)As with every color ereader using the E Ink Kaleido 3 screen technology, the Go Color 7 II has a screen resolution of 150ppi for color and 300ppi in grayscale. Colors appear more washed out when compared to its own predecessor which, at the time of writing the Boox Go Color 7 review, I said was pale beside the Kobo Libra Colour. And while I don’t expect the Gen II to match what I would see on an LCD display, I did expect it to be similar to its older sibling, if not better.

Newer firmware may have made the Gen I better at displaying colors, but the release notes for v4.1 on the Boox website make no mention of changes that would account for this improvement. The more saturated hues, however, do come at the cost of some details in darker areas being diminished, but this may not be a deal breaker for many readers of comics and graphics novels.
Image 1 of 2Compared to the Kobo Libra Colour (left), the Go Color 7 II (right) is yellower and text paler (Image credit: Sharmishta Sarkar / TechRadar)Image 2 of 2The lack of contrast is clear when seen closely (Image credit: Sharmishta Sarkar / TechRadar)What is truly disappointing is how the text is displayed, whether in ebooks or in speech bubbles – letters are fuzzy on the Go Color 7 II compared to the Gen I and the Go 7. Even the Kobo is better at displaying text.
The new Boox interface allows you to have custom styling for individual titles you’re reading, but enhancing text weight (or boldness) didn’t help, although setting the Dark Color Enhancement to its maximum improved the text a tiny bit, but note that you will lose further details in darker areas when reading in color. Switching to dark mode also made no difference as overall contrast is lacking.
Long story short, it’s hard to recommend the Boox Go Color 7 Gen II as an ereader.
Even compared to the Boox Go 7 (top), the Go Color 7 Gen II (bottom) is a lackluster ereader (Image credit: Sharmishta Sarkar / TechRadar)WritingIt’s hard to rate the Go Color 7 Gen II’s writing experience objectively as the Boox InkSense is no longer available (although it still works if you can find stock at a retailer) and will be replaced by a new stylus that I hope will add a touch of friction.
The hard plastic nib of the InkSense just slides across the screen of the Go Color 7 II, and I often felt like I was losing control over my writing because of that. I think a softer nib would be ideal, but we’ll just have to wait and see what Boox releases for its 2025 Go series 7-inch ereaders.
However, as with reading, the color ‘inks’ available for writing look washed out compared to what I’ve experienced on older Boox tablets like the Onyx Boox Tab Mini C, and black is the only option that stands out clearly.
Image 1 of 3There's no friction between the screen and the Boox InkSense, so writing isn't very paper-like (Image credit: Sharmishta Sarkar / TechRadar)Image 2 of 3There's a good color palette to choose from for writing and drawing... (Image credit: Sharmishta Sarkar / TechRadar)Image 3 of 3..but results appear paler than expected (Image credit: Sharmishta Sarkar / TechRadar)The native Notes app, though, is the same as you’d find on the brand’s more high-end epaper tablets like the Onyx Boox Go 10.3 and is more than enough for the average user who needs to jot down some thoughts or doodle. Power users would appreciate the Notes app better, thanks to several tools that could prove handy for productivity. For example, the Insert option allows you to add images and audio files to your notes, and the same tool lets you hyperlink selected text to an external URL or to a different page within the same notebook.
The adjustable Lasso tool gives you a lot of flexibility for text selections, and promptly adds the AI tool for instant handwriting-to-text conversion. Handwriting recognition is not always accurate, but then it’s very simple to make edits manually.
• User experience score: 2.5 / 5
Hopefully the redesigned stylus for the Boox Go 2025 series will be better than the InkSense (Image credit: Sharmishta Sarkar / TechRadar)Onyx Boox Go Color 7 Gen II review: PerformanceThe Boox Go Color 7 Gen II uses the Qualcomm Snapdragon 690 chipset paired with 4GB of RAM to keep things running as smoothly as possible. The CPU is a small improvement over the Snapdragon 680 used in the older Go Color 7, but it doesn’t seem to have made much of a difference in overall performance.
Boox tablets aren’t known for being speedy loaders, and the latest Kindle and Kobo ereaders boot up faster from sleep mode than the Go Color 7 Gen II. Even the native Library app takes its time to open a chosen title, even if it’s been saved locally to the device. It’s not a deal breaker in terms of overall usability, although it’s undeniably slower than the 2024 Kindles and Kobo devices when opening up a book to read.
Even wired file transfer via USB-OTG was very quick. Wireless transfer of files has always been easy using the BooxDrop platform, but I had no trouble signing into my Google Drive account either, with cloud transfer also working quite well.
Third-party apps, however, load quickly and, during my testing, worked smoothly, with no app crashes experienced with the few that I downloaded for this review. That said, reading on the Kindle or Kobo app also suffered from the same screen issues as when using the native NeoReader application.
Image 1 of 2There are options to tweak the text style on the Go Color 7 Gen II, both for comics/graphics novels... (Image credit: Sharmishta Sarkar / TechRadar)Image 2 of 2..and text-heavy ebooks, but they don't help the Go Color 7 Gen II very much (Image credit: Sharmishta Sarkar / TechRadar)My biggest performance issue with the Go Color 7 II was ghosting. Adjusting refresh rates using the presets available for individual apps didn’t help at all and the only way I found to counter this was to set system refresh rate to a faster option. I tested a full-refresh frequency set at 10 taps and 5 taps, with the latter working fine for the most part, although it came at the cost of battery life. There was still some ghosting on the display between the 5 taps, and the only way to eliminate this was setting full-refresh frequency to 1 tap. This drains the battery even more significantly, but was the best solution for me.
In fact, the preset refresh rates that can be set on a per-app basis didn’t even help smoothen stuttering while scrolling web pages on the native browser. I wasn’t expecting seamless scrolling like on a phone, but I’ve experienced better refresh-rate presets on other E Ink devices: case in point, I had no such problems in my ViWoods AiPaper review which also runs a custom version of Android 13 like the Go Color 7 II.
Image 1 of 3Dark mode doesn't improve readability very much, but it has its own quirks. It's fine when first switched on... (Image credit: Sharmishta Sarkar / TechRadar)Image 2 of 3..but the white floating bar gets distracting. (Image credit: Sharmishta Sarkar / TechRadar)Image 3 of 3Turn a page, though, and the bottom information bar becomes white, which is just as distracting as the floating toolbar (Image credit: Sharmishta Sarkar / TechRadar)As I’ve already mentioned, battery drain for me on this ereader was quite significant after I changed the system refresh rate to a quicker option, but even on default settings, the Go Color 7 II chews through its 2,300mAh battery quite quickly.
I had the ereader set to powering off after 48 hours of no activity, but upon switching the Go Color 7 II on again I found the battery life would be significantly lower than when I put it into sleep mode. I expect about 5% to 10% drain for ereaders in scenarios like this, but the Go Color 7 II would drop by 25% on average – in one instance where it was in sleep mode for 48 hours and powered down for a further 36 hours, battery life dropped from 81% to 56%.
This isn’t behavior I’ve experienced with any other Boox tablet, so I suspect there’s a bug that’s affecting battery efficiency and a future firmware might be able to fix it. In the meantime, you’ll still get about a week of reading from every top-up with the system refresh rate set to 15 taps. This will reduce if you use faster refresh rates and will also be affected by how bright you set the frontlight to and how often you use Bluetooth connectivity.
Recharging, thankfully, isn't slow and it went from 12% to full in 1 hour and 57 minutes plugged into a wall adapter during my testing. Connected to a dock slowed down the charging rate only marginally, going from 17% to full in 2 hours and 10 minutes.

Buy it if...You want a compact color ereader with writing capabilities
With a 7-inch color display, the Go Color 7 II is quite compact and very light too. And given it’s also got writing features built in, it’s versatile. Unfortunately, its many usability and performance issues makes it hard to recommend over similar devices.
Don't buy it if...Readability and performance are important to you in an ereader
The Go Color 7 II has potential, but its subpar screen and above-average battery drain leaves it trailing behind many of its contemporaries. If the color display isn’t important, you’ll be better off opting for the grayscale Go Color 7.
Value for money is important
Compared to its predecessor, the Go Color 7 is well priced as it adds writing features for the same cost. However, its lackluster user experience and lack of performance makes it hard to recommend at any price point.
You want a compatible stylus at the time you buy a device
It’s very strange for a brand to release devices that require an optional add-on that gets discontinued soon after their launch. Stranger still is that no replacement was made available at the time. So until Boox releases a replacement for the InkSense stylus, it’s hard to recommend the 2025 Go series ereaders.
Onyx Boox Go Color 7 Gen II review: AlternativesKobo Libra Colour
It's displayed colors might look washed out in comparison to the Go Color 7 II, but that means you can see a few more details in darker areas. It, too, allows you to read and write and Kobo's Advanced Notebooks are quite full featured. You will, of course, need to purchase the Kobo Stylus 2 separately if you want to use jot notes, but I think it's worth the additional ask. Compared to the Go Color 7 II, though, it's the better ereader and has a more streamlined interface.

Kobo Clara Colour
If you don't want the writing features, but the color screen is important to you, you can save quite a bit of cash opting for a 6-inch color ereader and I think the Kobo Clara Colour is the best option in that regard. Seamless performance and a compact form factor are just some of its attributes.

Amazon Kindle Paperwhite (2024)
The 12th generation Kindle Paperwhite is a fantastic 7-inch ereader with a black-and-white screen that I'd recommend if you're already part of the Amazon ecosystem. With direct access to the Kindle Store and a smoother interface than Boox, its E Ink Carta 1300 is one of the best optimized in the business.
Read our in-depth Amazon Kindle Paperwhite (2024) review
When Boox sent the Go Color 7 Gen II for review without a stylus, I was a little surprised. On enquiring, I was told that the Boox InkSense – the supported pen – had been discontinued and I would be sent its replacement as soon as it was released. However, that meant delaying this review until later this year, so I purchased the InkSense myself from a third-party retailer in Australia (where the the testing was done) who still had stock. The stylus is now no longer available anywhere.
It was fantastic to see that I didn't need to manually pair the stylus to the Go Color 7 II – it just worked. To test the writing features, I wrote some notes and tried doodling a little (I can't draw to save my life).
To test the Go Color 7 II as an ereader, I used USB-OTG to transfer a few ebooks, but also signed into my Google Drive account for cloud transfer of other files, including the Bookerly font family I'm partial to and some MP3s. I also 'pushed' a couple of existing files I had in the cloud via the BooxDrop platform as well.
I compared the Go Color 7 II to two other color ereaders: the older Boox Go Color 7 and the Kobo Libra Colour. I also compared it to its 2025 sibling, the Onyx Boox Go 7, as well as the 2024 Amazon Kindle and Kindle Paperwhite for direct text comparisons.
I listened to some audio files using the native music player. I downloaded a couple of other reading apps (Kindle and Kobo) and used the native web browser to see what the experience is like on an E Ink tablet.
I've tested more than 30 ereaders in the last eight years, giving me the knowledge and expertise to comment on the Boox Go Color 7 Gen II's usability and performance.

The River 2 has been out for a couple of years now, but I think it's a great buy due to the solid spec and increasingly cheap price. The unit tested here has been with me since launch and I have taken it on dozens of adventures without it skipping a beat.
Are you after the latest model instead? Take a read of our EcoFlow River 3 review and see if the updated version is better suited to your needs.
The River 2 is the smallest in EcoFlow's ultraportable River 2 power station series and it has a 256Wh capacity. Note that I tested the Australian spec model, but aside from a different AC plug depending on the country it's sold in, the underlying capabilities are the same.
The River 2 is basically a big battery bank combined with a 230V/120V inverter, high power USB and 12V outputs, and a range of charging ports. The River 2 can handle 300W AC appliances, with a surge capacity up to 600W.
The River 2 series is designed to be very portable, and is great for any charging or power needs when out and about. Not just for recreation either – it’s well suited for professionals who need to run equipment in the field – especially since it can be combined with solar for charging anywhere. The River 2 can also be used like a UPS, to automatically keep your modem or other critical devices powered on through a blackout.
Importantly, the River 2 series uses lithium iron phosphate (LFP) battery cells, which allows for a large amount of full cycles. The River 2 is rated at 3,000 cycles (100% to 0%) before capacity drops to 80% of the original. That means you could recharge it almost every day and it would take 10 years to drop to 80% of original capacity. Even then, with 80% capacity being around 200Wh, that's still a heap of juice.
On the front, the River 2 has a single 230V/120V AC power socket, a 12V/8A car-style DC accessory socket, dual USB-A ports (5V/2.4A) and a 60W USB-C PD input/output that can charge a laptop, or charge the power station itself. When plugged into the wall, the River 2 charges at up to 360W. That's fast, and means it can go from dead flat to full in just an hour – an incredibly handy feature when you need to recharge in a hurry. It also has a DC input port on the back that can accept 11-30V, and charge the battery at 110W. This means the power station can be quickly charged in the car (or 24V in a truck), or with a solar panel or other DC power source.
The River 2 has a screen that shows remaining charge, time until flat at current usage, and input/output wattage. That’s all that most users will likely need, but you can also connect to the power station using a slick app from EcoFlow. This provides all sorts of deeper functionality, like setting maximum charge and discharge levels, setting specific charge rates, updating the firmware and more.
I have really enjoyed my time with River 2, but of course there are some minor niggles. At higher loads, the River 2 does need a fan to keep internal temperatures down. It’s not especially noisy and doesn’t run all the time, but is potentially a way for dust to build up (and require occasional cleaning) over time. Otherwise most of the things I wish for (like a 100W USB-C output) are options on the larger capacity models.
The River 2 did command a somewhat premium price at launch but has been getting much more affordable over time and has had some great discounts lately. All in all, it offers an excellent mix of features that is well worth it for those who need reliable portable power on the go.

The River 2 has a very capable 256Wh battery and is ready to power all your devices no matter where you are. (Image credit: Future)EcoFlow River 2 review: price and availabilityThe River 2 has been out for a couple of years now and is easily available for much less than the launch RRP. The easiest place to find it is generally direct from EcoFlow, though it's also stocked on Amazon and at a large number of third-party retailers.
Generally speaking the River 2 is solid value, considering the focus on portability, unique features and long warranty. It also has fairly frequent sales that can bring it down to less than half price.
• Value score: 4 / 5
On the rear the River 2 has AC input for 360W charging, and a DC input for car or solar charging at 110W. (Image credit: Future)EcoFlow River 2: Design and featuresOne of my favorite features on the River 2 series is a completely non-technical one – the huge grab handle. Even though the unit is only 3.5kg, the handle makes it very easy to carry long distances, but doesn't make it too bulky to fit in a bag. My least favorite thing is the fan, which can get mildly noisy under load, and is a potential place for dust or water to get inside the River 2.
At 256Wh, the battery in the River 2 can be run flat very quickly (under an hour) if using the full 300W AC output. Lower power devices will run from hours to days, depending on the power use. Thanks to the huge 3,000 cycle life (to 80% capacity), you can fully discharge and recharge the River 2 multiple times in a day if need be, and rest assured the battery won’t wear out in a hurry. One thing to keep in mind is that the 256Wh capacity means the River 2 can’t be taken on a flight, as it's over the 160Wh limit most airlines use. For the full rundown of the rules, take a look at my guide on how to travel safely with a power bank.
It’s great to have a wide range of charging options on the River 2, but the clear standout is the very impressive 360W AC charge rate. I extensively tested the power station out and about, and being able to quickly grab some charge was very useful. While it takes just 1 hour to go from 0% to full, even just 5 minutes can bring back 10% charge. Charging in the car and using the solar mode is a fair bit slower (around 100W), but it was very handy when further afield, or camping. I also loved the USB-C charge option, as it made it easy to plug in overnight without using the bulky AC cable, and does not need to use the fan.

The 300W (600W surge) AC output is well-sized for most devices that might be used on the go, and the River 2 also has X-Boost, which allows certain high power devices (up to 600W) to be run at lower power without overloading the power station. The AC output can also be turned off completely via a button, or in the app, saving standby power. If the River 2 is plugged into the wall, and a device is plugged into the power station, then it automatically works as an Uninterruptible Power Supply. This is a handy extra feature, especially for when the River 2 is not being otherwise used. For example, it can be left plugged in to keep your modem running in the event of a blackout, or power critical things like a fish tank heater.
While the River 2 has a screen with key information, the more in-depth control is done via the app. It can connect via Wi-Fi and be managed even when away from home, or directly connected to (for example when camping) via Bluetooth. The EcoFlow app has options like being able to limit the maximum charge or discharge percentage of the power station, turn the outputs on and off, or set timeout periods. Importantly, the River 2 series is backed by an impressive 5-year warranty, which gives peace of mind that the power station will be with you for the long haul.
• Design and features: 4.5 / 5
While the River 2 can output 60W via USB-C, it can also charge itself, reducing the need to carry the bulkier AC cable. (Image credit: Future)EcoFlow River 2 review: Performance and testingThe River 2 series rates very well for portability, and the 3.5kg heft is very easy to carry with the sturdy grab handle. The unit has large rubber feet, and the plastic shell is robust. The ports on the front are well laid out and not too crowded, so plugging and unplugging multiple things is easy. The display is easy to read even in bright sunlight, though I wish the buttons were more recessed, as I found they could be accidentally pressed if the River 2 is in a bag.
I connected the River 2 up to a load tester for the 12V DC and USB outputs, and the ports all happily gave their specified wattages and voltages. The AC output provides clean power without dropping the voltage at full load, and the X-Boost functionality worked as intended to avoid shutdown at higher loads.
The River 2 real-world usable capacity depends on how fast you discharge it, and through what output, but overall efficiency is excellent, and generally under 10% of the rated capacity is lost in conversions. One minor niggle – charging power banks has mixed results, with some charging, and others only being able to charge the River 2. A workaround is to use a USB-C charger in the 12V socket, but it would be great if the River 2 had a USB-C input only port on the rear.
The River 2 fan won’t kick in for USB-C use, but will spool up to high speed if fast charging via AC, or running something that uses a significant amount of the 300W available. The AC charge rate can be limited in the app, and at the minimum 100W, the fan is quiet, but still audible. One minor frustration is that the fan speed control is overly enthusiastic, and often cranks up to full speed for a few seconds before dropping back.
I managed a full charge from dead flat in 58 minutes on AC, and at peak rates could restore 10% charge in just 5 minutes. Charging from USB-C took a touch over 5 hours. Solar and car charging worked well – though the solar voltage and amperage inputs are somewhat awkward compared to what typical portable solar panels provide. Still, a 100W solar panel (or the EcoFlow 110W panel) can easily charge the power station up in as little as 4 hours. For those who want more solar input, check out the River 2 Pro and Max. The River 2 is rated for a UPS switching speed of under 30ms, and in my testing I didn’t have an issue even with finicky, lower power electronics. That said, it's not quite a true UPS, so not designed for very sensitive equipment.
While excellent overall, the EcoFlow app doesn’t have as much detailed information as I’d like, like allowing tracking of solar collected (or other data logging), or viewing how many cycles the power station has done. I also feel it's a missed opportunity to add some automation options, like being able to schedule the outputs to turn on and off at certain times.

Notes
Rating
Value
The River 2 series has a fairly premium feature set, which results in a higher-end price tag. Compared to the limited competition, the River 2 excels in areas like battery cycle life, being compact and low weight, and the inclusion of USB-C charging.
4 / 5
Design & features
The River 2 includes a solid mix of features, without going overboard on options that will add mass without providing much extra utility. The key advantages are that it's lightweight, very portable, and flexible enough to be used every day for many years.
4.5 / 5
Performance
The River 2 performed above and beyond in all my tests, and was extremely reliable, yet rugged enough that it does not need to be treated too gently. All the outputs (and inputs) happily sustained their full wattages for the entire battery capacity, even in (simulated) hot and cold conditions.
4.5 / 5
Buy it if...You need an ultraportable solution
The large grab handle and low weight of the River 2 mean it's just begging to be taken out on adventures. Bring an electric throw rug when stargazing in winter, hold your own movie night in the park, take it camping and more.
You will use the River 2 a lot
With a standout 3,000 cycle battery longevity, the River 2 is perfect for heavy use, and is well suited for everything including home or day-to-day use, camping, or for professionals who need power in the field.
256Wh is enough capacity for your charging needs
If you need a larger battery capacity between recharges, then consider the heavier, but even more capable 512Wh River 2 Max, or 768Wh River 2 Pro. Or even the larger Delta Series, like the 2016Wh Delta Max.
If you need to power high wattage appliances
300W of AC power (100W DC at 12V, 60W USB-C) is enough for most smaller appliances and gadgets, but not everything. Items like power tools, or appliances for cooking, all need a higher AC output, and more storage capacity.
Silence is important
The fan in the River 2 is fairly quiet most of the time, and only really ramps up to noisier levels under heavy load, or when rapidly charging. But even at its lowest setting, the fan is audible – especially on a quiet night.
You need a waterproof and dustproof power station
While the River 2 can handle normal outdoor use just fine, it’s not waterproof and needs some protection from the elements. The fan is also a dust entry point and the power station does not have covers on the ports.
Overall the River 2 is a very competent little power station that is well suited to a variety of uses. It focuses on portability over maximizing features and spec – leaving that for the larger River 2 Max and Pro. The River 2 is powerful enough to be a worthy addition to your next camping trip, and combined with a solar panel, makes it possible to keep devices charged indefinitely. Other options like the UPS functionality mean the River 2 is also useful at home between adventures.
The 256Wh capacity is well suited to daily use, and the fast charge ability makes it very easy to top up any time. The ability to silently charge from USB-C is great for nighttime use, or just for avoiding needing too many cables. The long 5-year warranty and 3000 cycle battery longevity mean the River 2 can be pushed hard without worrying about a shortened lifespan. The EcoFlow app is quite slick, but a little lacking when it comes to deeper levels of control and data logging.
While the power station isn’t perfect, and larger Max and Pro models might suit some users better, the River 2 is a great option.

Google’s NotebookLM first debuted its AI-powered research tool with Audio Overviews capable of making AI-produced 'podcasts' with digital hosts. The logical extension into Video Overviews followed, with a synthetic voice accompanied by a series of slides that include text and illustrations. However, that capability was only available in English until now.
NotebookLM Video Overviews are now available in more than 80 languages. For most people, that translates to translatable versions of video walkthroughs based on your uploaded notes and linked source materials. The AI professor is already there and is now a multilingual expert as they present your own content in everything from Tamil to Polish and beyond.
These aren’t AI summaries scraped from the web or hallucinated based on a vague prompt. NotebookLM is grounded in the actual material you upload. Everything the AI says, in video or audio, is pulled directly from your documents, not from generic training data.
Of course, the video in this context isn't a cinematic masterpiece. The slides are not fully animated explainers. This isn’t TikTok for term papers; it’s more like PowerPoint for people who don’t want to make PowerPoints. The goal is clarity, not spectacle.
Global AI videoThat's not the only global upgrade to NotebookLM, though. While Audio Overviews had been available in many languages recently, they were limited to brief highlights. Now, everyone gets the complete audio AI experience as an alternative to the video option.
For those who might want to read a white paper while driving or cooking, this is enormously practical. It won’t win a Grammy, but it might just help you understand a textbook or complex report. Professionals working internationally could use it to summarize a week’s worth of meeting transcripts as shareable videos or audio recaps from Catalan to Portuguese. No need to rely on a colleague’s English comprehension.
If you want to see how AI can digest and explain your collection of academic papers, blog posts, and YouTube videos, you can produce a narrated video by uploading your sources as usual, then clicking on the Video Overview button. Shortly, a video of approximately seven minutes will be ready for you to share, download, or use as you wish.
That’s not to say this solves everything. The AI can still struggle with nuance, for instance. But the reliability of the presentations is valuable on its own. Now, they just look good too.

The most recent high-profile incident occurred when English folk singer Emily Portman heard from a fan who liked her new release, except the album, Orca, though released under her name, was entirely fake. The whole thing had been pushed live on Spotify, iTunes, YouTube, and other major platforms without her knowledge or consent.
A post shared by Emily Portman (@emilyportman)

Portman took to social media to warn her fans about what was happening. The fact that the AI could mimic her artistic style well enough to trick some fans just added to the creep factor. It took weeks for Spotify to address the problem, and you can still see the album on Spotify even if the music is gone.
Portman joins a litany of acts, from pop artist Josh Kaufman to country artists Blaze Foley, who passed away in 1989, and Guy Clark, who died in 2016, in having her work mimicked by AI without her approval.
It seems we’ve moved past the novelty of AI remixes and deepfake duets into digital identity theft with a beat. The thieves are often good at being quiet in their releases, able to score whatever royalties might trickle in.
Further, even getting the music taken down might not be enough. A few days after the initial incident, Portman found another album had popped up on her streaming page. Except this time, it was just nonsense instrumentals, with no effort to sound like the musician.
AI's future soundsHaving scammers use AI to steal from actual artists is obviously a travesty. There are some blurry middle grounds, of course, like never-real musicians pretending to be humans. That's where AI-generated “band” Velvet Sundown stands.
The creators later admitted the origin of the AI band, but only after millions of plays from a Spotify profile showing slightly uncanny images of bandmates that didn’t exist. As the music was original and not directly ripped from other songs, it wasn’t a technical violation of any copyright laws. The band didn’t exist, but the royalties sure did.
I think AI has a place in music. I really like how it can help the average person, regardless of technical or musical skills, produce a song. And AI tools are making it easier than ever to generate music in the style of someone else. But, with streaming platforms facing 99,000 uploads a day, most of which are pushed through third-party distributors that rely on user-submitted metadata, it’s not hard to slip something fake into a real artist’s profile. Unless someone notices and complains, it just sits there, posing as the real thing.
Many fans are tricked, with some believing Orca was really Emily Portman’s new album. Others streamed Velvet Sundown, thinking they’d stumbled onto the next Fleetwood Mac. And while there's nothing wrong with liking an AI song per se, there's everything wrong with not knowing it is an AI song. Consent and context are missing, and that fundamentally changes the listening experience.
Now, some people argue this is just the new normal. And sure, AI can help struggling artists find new inspiration, fill in missing instrumentation, suggest chord progressions, and provide other aid. But that’s not what’s happening here. These are not tools being used by artists. These are thieves.
Worse still, this undermines the entire concept of artistic ownership. If you can make a fake Emily Portman album, any artist is at risk. The only thing keeping these scammers from doing the same to the likes of Taylor Swift right now is the threat of getting caught by high-profile legal teams. So instead, they aim lower. Lesser-known artists don’t have the same protections, which makes them easier targets. And more profitable, in the long run, because there’s less scrutiny.
And there's the issue of how we as music fans are complicit. If we start valuing convenience and novelty over authenticity, we’ll get more AI sludge and fewer real albums. The danger isn’t just that AI can mimic artists. We also have to worry that people will stop noticing, or caring, when it does.
