Branding is minimal and unobtrusive, with solely the “BOOX” title on the “backbone” and the again of the system. There’s an uncommon strip of matte plastic with decals on that very same facet, giving the pill a little bit of persona whereas additionally offering a greater grip. In any other case, a lot of the Boox Tab Extremely C’s physique is produced from sturdy and aesthetic aluminum, one other level of departure from common eReaders.

Onyx ships the system with a Pen 2 Professional that matches its coloration and construct high quality. This aluminum stylus magnetically latches onto one fringe of the Boox Tab Extremely C, so that you gained’t must fumble with a separate holder or sheath. The barrel is generally spherical, save for the flat edge that sticks to the pill and likewise prevents the pen from rolling off a flat desk. The ridged cap of the pen is, sadly, just for present. It capabilities as an eraser within the built-in Notes app, however you’ll be able to’t twist or flip this half, regardless of what its design suggests.

Onyx sells an non-obligatory magnetic keyboard case that basically drives dwelling the truth that the Boox Tab Extremely C leans extra towards the pill facet of the fence. The keyboard connects to the pill by way of Pogo pins, so that you gained’t have to fret about flaky Bluetooth or lifeless batteries. The quilt is supposedly made with synthetic leather-based, nevertheless it feels extra like rubbery silicone than any premium materials. It doesn’t entice fingerprints as marketed, nevertheless it’s a mud and mud magnet as an alternative, making that “function” moot.


The very first thing you’ll discover once you elevate the Boox Tab Extremely C from its field is that it’s considerably heavy. At 480g (1.06 lbs), it’s in all probability one among if not the heaviest E Ink studying gadgets you may get your fingers on, no less than inside the identical 10-inch measurement class. A part of that is because of the usage of extra sturdy but in addition heavier aluminum, and a part of it’s merely as a result of quantity of {hardware} inside. Extra on that in a bit.

What this implies, nonetheless, is that the Boox Tab Extremely C is uncomfortable to carry unsupported with one hand for a protracted time frame. Some may even already really feel some pressure for just some minutes, not to mention half an hour of steady studying. Admittedly, leisurely studying books isn’t the core function of this system anyway. As a substitute, it’s a tool that brings collectively the ability and adaptability of an Android pill with the consolation and longevity of an E Ink display, making it extra of a productiveness instrument than a mere eBook reader. It’s, in a means, nearer to an iPad Professional or a Galaxy Tab S8 in operate and nearer in weight class as effectively.

The Pen 2 Professional that Onyx ships within the field is mild and well-balanced, making it an incredible instrument for writing and sketching. The flat fringe of the barrel is a pure resting spot for the fingers, including to the pen’s grip. There aren’t any buttons to be cautious of, although that additionally means there isn’t a extra performance out there. The highest of the pen solely works as an eraser, no less than in apps that may acknowledge it as such.

The Boox Magnetic Keyboard Cowl provides safety to the pill, however at 408g (0.9 lbs), it additionally doubles the pill’s general weight. It’s positively one thing you’ll need to take off in case you’re not utilizing the keyboard or carrying the Boox Tab Extremely C round. Fortunately, the magnets align the pill and the quilt completely, so that you gained’t lose an excessive amount of time placing it on once more. Like nearly all keyboard covers of its sort, there’s just one viewing angle, which isn’t precisely the perfect ergonomic place. For typing on the go and away out of your desk, it’s virtually the one possible place anyway.


It might have an E Ink display on prime, however the Onyx Boox Tab Extremely C is an Android pill at its very coronary heart. Powered by a Qualcomm Snapdragon 662 with 4GB of RAM and a beneficiant 128GB of expandable inside storage, it’s the equal of a mid-range Android pill, no less than from two or so years in the past. It’s no racehorse, in fact, nevertheless it’s positively probably the most {powerful} chipset to grace an E Ink system. That is particularly vital because the Boox Tab Extremely C comes with Google Play Retailer pre-installed, which implies you’ve got entry to all of the Android apps you’ll be able to ever need.

Because of this potent mixture, the Boox Tab Extremely C is presumably probably the most succesful E Ink pill available in the market so far. Onyx’s customized UI is snappy and responsive, and apps launch rapidly and carry out fairly decently. These coming from common tablets may level out the small pauses when utilizing apps, however that is extra as a result of ePaper panel refreshing its contents somewhat than sluggishness on the pill’s half. These used to common eReaders will certainly come off impressed by the system’s clean efficiency.

The pill comes with a 6,300 mAh battery, which is unquestionably a lot for an E Ink system. That mentioned, the pill’s precise uptime goes to be shorter than your typical eReader in case you have a tendency to make use of extra apps outdoors of fundamental studying and note-taking. With entry to so many apps, you may be tempted to run wild, particularly because the system is greater than able to supporting these. The stereo audio system are a lot loud, for instance, and the Ultrafast refresh mode even makes YouTube usable. You possibly can even play some video games in case you’re as much as some grainy graphics and loads of ghosting.

The Boox Tab Extremely C’s killer function is, in fact, its 10.3-inch Kaleido 3 E Ink display, the present king in the case of coloured ePaper shows within the shopper market.

With coloration, the density dips to 150dpi, which is definitely nonetheless increased than earlier coloured E Ink applied sciences.

After all, not all content material is identical, so Onyx gives controls that allow you to combine settings to your tastes. With heat and funky brightness settings, you can too tweak the show to your consolation, guaranteeing that you just don’t lose the eye-friendly advantages of E Ink even with all the colour and energy the system provides.


Onyx deserves props for selecting aluminum over plastic for the Boox Tab Extremely C’s physique, even when its different fashions haven’t made the change but. Its packaging can be easy and compact, although it nonetheless has the customary plastic wrappings and sections. Onyx doesn’t ship a charger with the system, although it comes with a USB-A to USB-C cable for charging and information switch functions. Sadly, that is the naked minimal effort that shopper electronics firms are speculated to make, and we’re hoping that Onyx will differentiate itself additional with a stronger sustainability dedication quickly.

The slight upside is that Onyx’s gadgets are made to final, each in {hardware} and particularly in software program. Individuals don’t change eBook readers as typically as, say, telephones and tablets, and the Boox Tab Extremely C is not any completely different. This explicit pill has simply sufficient energy to hold it for years, which can be how lengthy Onyx normally pushes out software program updates. For its function and design, you gained’t be going after probably the most resource-intensive apps anyway, so that you’re unlikely to chase after new specs and options for a protracted whereas.


As {powerful} and as spectacular because the Onyx Boox Tab Extremely C is, it’s in all probability not going to be everybody’s cup of tea, simply as not everybody may be available in the market for an everyday pill. Even those that have been dreaming of studying colourful comics and magazines ever because the earliest days of eBook readers may be on the fence about whether or not to seize this explicit system or not.

Whereas its A5-sized display is nice for studying magazines, PDFs, comics, and paperwork, it isn’t probably the most handy factor to learn on, particularly in case you think about its heft. The largest deal breaker, nonetheless, is the $600 price ticket hooked up to the system, making it one of the vital costly eReaders on the market. And that’s not but contemplating the $110 magnetic keyboard cowl that turns the system right into a handy and eye-friendly productiveness instrument.

That’s to not say that there’s no marketplace for the Onyx Boox Tab Extremely C as a result of it occurs to be one of many firm’s latest successes. You simply must method it with the correct way of thinking, not as a big coloured eReader however as an Android pill with a coloured E Ink show.
