Excessive-end e-ink units are nonetheless a reasonably new idea however the Onyx Boox Tab Extremely makes a compelling case for his or her existence.

Whereas Amazon has led the cost on e-ink know-how with its vary of Kindle e-readers, we’re now beginning to see different corporations throw their hats into the ring by reinventing how e-ink may very well be used past the e book expertise.

I lately reviewed the Outstanding 2 which is a superb digital pocket book that superbly recreates the sensation of pen and paper, and now Onyx is seeking to transfer the ceiling for what’s doable on an e-ink machine.

As its title suggests, the Tab Extremely is choosing a no-holds-barred e-ink expertise, and it’s even marketed as a ‘Pill PC’ on Onyx Boox’s web site. On condition that the machine runs full Android 11, I used to be intrigued to see if Onyx may really ship on the Tab Extremely’s high-end idea, and after spending a number of weeks with it, I can safely say that it’s an expertise like no different.


  • Light-weight sufficient to be held one-handed
  • A texturised strip on the again to assist with grip
  • Very skinny at simply 6.7mm thick

Proper off the bat, the Onyx Boox Tab Extremely feels tremendous glossy within the hand. In comparison with the lofty bezels discovered on the Outstanding 2, the Tab Extremely retains issues loads slimmer with solely a bigger portion on the left-hand facet to your thumb to relaxation in opposition to.

Even with a big 10.3-inch show, the machine is simple to carry one-handed, weighing in at simply shy of 480g. The included stylus can snap magnetically to the right-hand facet of the machine, and with the entire thing solely being 6.7mm thick, it could possibly simply slide in beside a laptop computer in your rucksack.

Very like the Outstanding, there’s just one bodily button and it’s used for waking up the Tab Extremely or for placing it again into standby mode – all different inputs are made through the touchscreen.

On the again of the machine, there’s a small little bit of aptitude with a texturised panel designed to supply some grip for the remainder of your fingers when holding the machine, which is all the time a welcome consideration. What you could discover nonetheless is that the branding on each the back and front is in panorama mode, which simply goes to indicate how assured Onyx is within the Extremely’s PC-style options, very similar to how we’ve seen Apple change to embrace the choice for panorama in its iPad vary over the previous couple of years.


  • 10.3-inch display
  • Chilly and heat backlights included
  • Spectacular refresh charges

Despite the fact that its characteristic set far outweighs that of the Outstanding 2, each units share similar specs with regards to their shows, with the identical 10.3-inch display and a 1872 x 1404 decision.

I’ll say that when utilizing the built-in apps like notebooks, and studying something downloaded through the Onyx Boox retailer, all of it appears very crisp and simple on the eyes however there’s a noticeable softening when utilizing some third-party apps. Textual content is slightly softer on the Kindle app as an illustration, so that you’ll nonetheless discover a higher studying expertise for the Amazon ecosystem on the corporate’s own-brand e-readers.

What completely works within the Tab Extremely’s favour although is the presence of a backlight. The dearth of such a characteristic on the Outstanding 2 finally held it again from greatness, however on the Tab Extremely it’s a Godsend, so you may hold studying and dealing nicely into the night time with out the necessity for an exterior gentle supply.

That is notably helpful for me as I’ve swapped over to utilizing the Tab Extremely for any last-minute bits of labor earlier than retiring for the day, and located the expertise to be much more forgiving on my eyes than a smartphone or conventional pill.

There’s even a warm-light constructed into the system, which is much better fitted to these moments when there’s completely no gentle sources round you and a brilliant blue backlight could be an excessive amount of to take care of.

It’s additionally value mentioning that the Tab Extremely doesn’t use the identical paper-like coating above the show that may be discovered on the Outstanding 2. Whereas this doesn’t smash the note-taking expertise by any means (actually it’s a quicker expertise total on the Tab Extremely), it doesn’t get fairly as near the sensation of pen and paper that the Outstanding is ready to obtain.

Not like its rivals nonetheless, the Tab Extremely does allow you to select between a number of refresh modes, serving to to hurry issues up in the event you’re taking over extra demanding duties and guaranteeing that the display doesn’t get too cluttered with the ghosting impact that you simply often see on an e-ink show.


  • Runs full Android 11
  • Full entry to the Google Play Retailer
  • The accompanying app may use some work

In comparison with most e-ink units, which are inclined to solely be good for a spot of studying and note-taking, the Onyx Boox Tab Extremely exists on a very completely different stage. This is because of the truth that, in contrast to its rivals, the Tab Extremely runs on Android 11, which means that you’ve full entry to the Google Play Retailer and the apps therein.

Not like the Outstanding 2, I’ve been ready to make use of the Tab Extremely to verify my Gmail inbox, my to-do record in Notion and even add to this exact same evaluation through Google Docs. It’s as strong an expertise as I’ve but to seek out on an e-ink machine and when paired with the keyboard case that Onyx sells, you may genuinely use the Tab Extremely as a productiveness machine, very similar to you’d an iPad.

As beforehand talked about, the presence of the Google Play Retailer additionally means you could obtain the Kindle app, providing you with entry to Amazon’s evergrowing treasure trove of ebooks. As if that wasn’t sufficient, the truth that there’s Bluetooth built-in means you could additionally join a pair of headphones and take heed to audiobooks, podcasts, songs and extra through the likes of Spotify, YouTube and Audible. You may even customise your homepage with widgets, very similar to how you’d on a typical Android smartphone.

Simply once you thought the characteristic set was ample sufficient, flip the Tab Ulta over and also you’ll spot a 16MP digital camera – sure, a digital camera. Don’t get too carried away, it’s not the kind of sensor you’d use for taking vacation snaps, however quite for scanning paperwork you could then convert right into a PDF and scribble throughout with the stylus.

Even in darkish environments, the digital camera does an ideal job of analysing textual content and presenting a clear look on the back-end, even when smaller bits of textual content are inclined to get squished collectively. All of that is helped by the Qualcomm octa-core chipset operating the present, which additionally contributes to the Tab Extremely’s spectacular speeds – simply the quickest I’ve ever seen for a tool like this.

To have this a lot performance accessible is slightly surreal, notably after simply having used the Outstanding 2 which prides itself on maintaining issues easy. On the one hand, it’s unbelievable, and I’ve been utilizing the Tab Extremely to dive again into items of labor after my eyes really feel slightly strained from utilizing a blue-light emitting show, however I’ve been much less inclined to make use of the machine for handwritten notes consequently.

This isn’t to say that the writing expertise is unhealthy, removed from it. The response time is tremendous quick and crucially, the Onyx Boox pen is included from the get-go which ought to be commonplace observe throughout the board. It nonetheless boggles my thoughts that the Outstanding Marker is offered individually from the primary pill.

My concern is that the handwriting UI provides you too many choices to the purpose the place it could possibly really feel slightly convoluted. One take a look at how the Tab Extremely’s UI compares to Outstanding’s ought to reveal my level instantly. You’ve bought the flexibility to set a number of forms of pens and pencils you could change between immediately, insert hyperlinks subsequent to your writing and even add recordings to a web page.

This would possibly enchantment to some however when all I wish to do is get away from incoming emails, notifications and Slack messages to jot one thing down, the very last thing I would like is one other cluttered web page to come back after my consideration. The accompanying Boox Assistant app additionally suffers a bit from this design mindset.

For starters, the app merely refused to sync my notes from the Tab Extremely as a result of I had initially logged into the app with one other Onyx Boox pill, and the one repair I may discover was to delete the app completely and restart the login course of. On high of that, the homescreen throughout the app is simply complicated.

As a substitute of the Outstanding app which takes you straight to your most up-to-date notes (which is why I’d wish to dive into the app to start with), you’re introduced with a number of choices with none clear clarification as to what they’re. All of it begins to make sense after spending a protracted period of time diving into the app, however I don’t perceive why it needs to be so obtuse from the get-go.


  • Giant 6300 mAh cell included
  • You will get a number of weeks of use on a single cost
  • Takes roughly two and half hours to totally cost

In a quite unusual break from tech custom, Onyx doesn’t really specify a claimed battery life for the Tab Extremely, aside from to say that there’s a 6300 mAh cell contained in the machine. This has solely made the method of testing the battery life, which often quantities to a number of weeks of use on different e-ink units, even trickier.

What I can say is that I’ve been ready to make use of the Tab Extremely sporadically, utilizing it to edit Google Docs in the future, take some handwritten notes on one other and even pop on a YouTube video, and in roughly every week and a half I’ve solely managed to whittle the battery all the way down to 30%, which is spectacular compared to a standard Android pill.

Charging the machine to 100% from a lifeless battery took roughly two and a half hours which is par for the course with one of these machine and on the very least, it’s one thing you received’t should do typically given how lengthy the battery lasts, so that you’ll have ample time to cost the Tab Extremely when it’s handy for you.

Last Ideas

On a technical stage, the Onyx Boox Tab Extremely is like nothing I’ve ever seen earlier than. I by no means anticipated to have YouTube movies play easily on an e-ink display, nor did I anticipate angling up a shot through a digital camera on that very same sort of show. It’s to this point forward of the competitors in efficiency that it feels nearly comical. Should you spend money on one e-ink machine, you then’ll be exhausting pushed to be disillusioned with what’s on supply right here.

With that mentioned, I nonetheless see myself counting on the Outstanding 2 after this evaluation as its simplicity and easy-to-use ecosystem make it the right antithesis to a fully-featured laptop computer, and ultimate for these moments the place I simply must get away from infinite notifications.
