The best e-ink tablet I’ve tested was not made by Amazon or ReMarkable

My lifestyle requires constant travel — from visiting family to catching flights to the Southern hemisphere, I’m never in one place for long. So when I heard about the Onyx Boox Tab Ultra, the company’s latest e-ink tablet that featured a portable digital scanner, I immediately jumped at the chance to take it with me on the go. I’ve had it for a month now, and while it’s the best e-ink tablet to date that I’ve tested thanks to major upgrades in some specs, it’s not without its flaws. Let me break it down.

Specifications

Design

If you’re looking for a light tablet to take on the go, heads up: the Tab Ultra is one hefty beast. It’s much heavier than its sibling, the Onyx Boox Tablet Note Air 2 Plus — I attribute that to the 16MP camera built into the frame. It’s also thicker to carry, but unless your carry-on is notoriously short on space, no need to sweat these larger dimensions.

The screen’s glass also received a much-needed upgrade from its sibling, offering a smoother writing experience that’s noticeably more akin to writing on paper. Onyx also kept the best parts of the predecessor, still offering an 1872 x 1404 Carta (227 dpi) resolution, a practical and adjustable warm light, and a 10.3-inch touch screen. All of that contributes to what I consider to be the smoothest writing experience on an e-ink tablet to date. 

A fresh approach to software

I’ve tested a number of tablets from Onyx, so it was easy for me to notice the rather jarring change to the Ultra’s new home hub interface. The new layout removed the side tabs and added my notes to an easy-access section on the home page. When I turn it on, with one tap, I can go back to my most recent notes — a feature that proved itself useful very quickly. The apps also lost their own tabbed section, but display prominently on the home screen too, and I could adjust their location with ease.

One of the coolest features, however, is the new ability to adjust the screen’s refresh rate modes. The tablet offers four: HD, balanced, fast, and ultrafast. A faster refresh rate yields smoother animations at the expense of shorter battery life. A slower refresh rate, which would be ‘HD’, lends to more static visuals and longer endurance. Still, it’s wonderful to be able to adjust the refresh rate based on the task at hand.

Performance

As I said before, Onyx enhanced the protective glass, but it also upgraded the processor, opting for a Qualcomm Octa-core model this time around. This results in faster and more accurate inputs with the stylus, and little to no lag experienced throughout the apps and services. I even found myself — dare I say it — enjoying my Danish Duolingo practice on this tablet due to the enhanced performance.

I also enjoyed using the Pen 2 Pro that came bundled with the tablet, a smart pen that has a handy, built-in eraser function. (You’d be surprised how many manufacturers typically don’t include a stylus with their e-ink tablets, let alone one with a digital eraser.) For the price of it all ($599), having the pen included made the Onyx Boox Tab Ultra worth the upgrade from the Note Air 2 Plus.

The implementation of a new 16MP camera for scanning notes was also a welcome sight — but with depressing results (see comparison photos below). I tested it on Tolkein’s The Children of Hurin. In theory, it’s a wonderful addition to an already great tablet. However, in practice, it couldn’t produce any legible text conversions. In fact, the digital version misplaced a lot of the elements, rendering the import useless. If text scanning is important to you, I wouldn’t rely on the Tab Ultra to get the job done.

Bottom Line

If you need a handy tablet that combines your e-reader, work notes, and the ability to at least capture images with a camera, the Onyx Boox Tab Ultra is one of the best options available. You’d be hard-pressed to find another e-ink tablet that comes with this much onboard storage (128GB) and processing power. As for those that need a scanner that can convert texts into digital files, I’d advise you to wait for future models of the tablet or opt for a scanner on a phone. 

At $599, the price for the Tab Ultra seems a little steep. However, keep in mind that you’re not solely getting a tablet. You’re also getting the Boox Pen 2 Pro, a stylus case, a tablet case, a tote bag, and replacement pen nibs for the long run.

Alternatives to consider

We get it, sometimes you don’t want to spend $600+ on a top-of-the-line (and top-of-the-budget) e-ink tablet. So, here are some worthy alternatives for you to consider below.

Looking for just an e-reader and a note-taker for school? The Kindle Scribe offers both of these features. Amazon’s latest e-reader also comes with a similar warm reading light as the Onyx Boox for those late study nights on its 10.2-inch, 300ppi screen. Read the full review here.

Unsurprisingly, the ReMarkable 2 tablet is often mentioned when talking about what the best e-ink tablet is. While the device doesn’t offer the most comprehensive reading platform, especially when compared to the Kindle Scribe above, it dials into a remote cloud system for storage and features a robust note-taking experience thanks to the bundled pen. Read the full review here.

The older sibling to the Tab Ultra still offers a bunch of great specs for the price, including a 10.3-inch screen for taking notes, reading, and more. It was designed with artists in mind, offering layering functions, zooming in and out of notes, and multiple digital pen tips for digital creations. Read the full review here.
