Going far past what’s normally anticipated from an e-ink machine, the Onyx Boox Tab Extremely is a full-on Android pill that mixes the advantages of e-ink expertise with the wealth of apps on the Google Play Retailer.


  • Full entry to the Google Play Retailer
  • Quick efficiency regardless of its e-ink expertise
  • Writing is clean and fluid
  • The keyboard accent is sensible right here


  • The UI lacks the simplicity of the Exceptional 2
  • Accompanying app wants some work

  • Heat and chilly backlights included:Designed for night-time and low-light studying

  • 16MP rear-facing digicam:Scan and share paperwork rapidly


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 expertise with its vary of Kindle e-readers, we’re now beginning to see different firms throw their hats into the ring by reinventing how e-ink might be used past the e-book expertise.

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

As its identify 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. Provided that the machine runs full Android 11, I used to be intrigued to see if Onyx might 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 modern within the hand. In comparison with the lofty bezels discovered on the Exceptional 2, the Tab Extremely retains issues quite a bit slimmer with solely a bigger portion on the left-hand aspect on your thumb to relaxation towards.

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

Very similar to the Exceptional, 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 chances are you’ll discover nevertheless 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 like how we’ve seen Apple swap to embrace the desire for panorama in its iPad vary over the previous couple of years.


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

Though its characteristic set far outweighs that of the Exceptional 2, each units share similar specs in relation 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 seems very crisp and straightforward on the eyes however there’s a noticeable softening when utilizing some third-party apps. Textual content is just a little softer on the Kindle app as an example, 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 shortage of such a characteristic on the Exceptional 2 finally held it again from greatness, however on the Tab Extremely it’s a Godsend, so you possibly can preserve studying and dealing properly into the night time with out the necessity for an exterior mild supply.

That is significantly 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 suited to these moments when there’s completely no mild sources round you and a brilliant blue backlight is likely to be an excessive amount of to cope with.

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 Exceptional 2. Whereas this doesn’t damage the note-taking expertise by any means (in truth it’s a quicker expertise general on the Tab Extremely), it doesn’t get fairly as near the sensation of pen and paper that the Exceptional is ready to obtain.

In contrast to its opponents nevertheless, 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 up 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 might use some work

In comparison with most e-ink units, which are likely to solely be good for a spot of studying and note-taking, the Onyx Boox Tab Extremely exists on a totally totally different stage. This is because of the truth that, not like its opponents, the Tab Extremely runs on Android 11, that means that you’ve got full entry to the Google Play Retailer and the apps therein.

In contrast to the Exceptional 2, I’ve been in a position to make use of the Tab Extremely to verify my Gmail inbox, my to-do listing in Notion and even add to this exact same evaluation through Google Docs. It’s as sturdy 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 possibly can genuinely use the Tab Extremely as a productiveness machine, very like you’d an iPad.

As beforehand talked about, the presence of the Google Play Retailer additionally means which 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 which 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’ll be able to even customise your homepage with widgets, very like how you’d on a typical Android smartphone.

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

Even in darkish environments, the digicam does an awesome job of analysing textual content and presenting a clear look on the back-end, even when smaller bits of textual content are likely 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 obtainable is just a little surreal, significantly after simply having used the Exceptional 2 which prides itself on conserving 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 just a little strained from utilizing a blue-light emitting show, however I’ve been much less inclined to make use of the machine for handwritten notes in consequence.

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

My situation is that the handwriting UI provides you too many choices to the purpose the place it may really feel just a little convoluted. One have a look at how the Tab Extremely’s UI compares to Exceptional’s ought to show my level instantly. You’ve bought the power to set a number of forms of pens and pencils which you could swap between immediately, insert hyperlinks subsequent to your writing and even add recordings to a web page.

This may 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 want is one other cluttered web page to return 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 might 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 an alternative of the Exceptional 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 offered with a number of choices with none clear clarification as to what they’re. All of it begins to make sense after spending a chronic period of time diving into the app, however I don’t perceive why it must be so obtuse from the get-go.


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

In a moderately 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 normally quantities to a number of weeks of use on different e-ink units, even trickier.

What I can say is that I’ve been in a position to make use of the Tab Extremely sporadically, utilizing it to edit Google Docs sooner or later, 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 conventional 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 the sort of machine and on the very least, it’s one thing you gained’t must do usually 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 digicam on that very same sort of show. It’s to this point forward of the competitors in efficiency that it feels virtually comical. In the event you spend money on one e-ink machine, then you definately’ll be onerous pushed to be upset with what’s on provide right here.

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