The Boox Tab Ultra is much more than just an e-ink reader that also has the ability to scribble on documents. Android is used on the Tab Ultra, which differentiates it from other tablets that use e-ink displays. You read that right—the Android you already know and love is now available on devices with e-ink displays. As a consequence of this, you can use Chrome to run the complete suite of Google apps, view videos on YouTube, and navigate the internet.
It does not compete with anything else on the market due to the fact that it is packed to the gills with features. However, with a price tag of $600, it comes at a premium. Should you put that much money toward purchasing the most powerful e-ink tablet currently available on the market? After using the apparatus for more than a month, we are able to provide you with a definitive response.

Onyx Boox Tab Ultra: Design

If you like black slabs, the Onyx Boox Tab Ultra doesn’t change much from this style. The back of the Tab Ultra has a nice strip of icons that looks a bit like a computer geek’s take on Louis Vuitton’s signature pattern. Other than that, the tablet looks very sleek and professional.
Because E Ink displays don’t allow real backlighting, these ereader tablets usually have a big side-light bezel, but Onyx did a great job of making the Tab Ultra look more like a tablet than a book. It has a bigger edge than an iPad, but I like that because it makes it easier to read. You can buy this tablet from its official website
Onyx Boox Tab Ultra: Camera
The 16MP camera on the back of the Onyx Boox Tab Ultra is what makes it stand out. No other E Ink tablet has a camera on the back. Even though an E Ink display isn’t the best choice for a viewfinder, the Tab Ultra can still take pictures and even use the display to focus and frame documents. Most of the time, it works, but not often enough to be worth the price. I thought this camera would scan papers much better than the camera on my phone.
Software and Performance

The Qualcomm Snapdragon 662 chip runs the Boox Tab Ultra, which also has 4GB of RAM and 128GB of storage. Even though it doesn’t look like enough on paper to be an Android tablet, the Boox Tab Ultra is the most powerful e-ink tablet because of its specs. It runs Android 11, which is two versions behind, but it’s not a big deal because it’s heavily covered with Boox’s software. We quickly learned how to use the motions and move around.

Pricing and availability
Amazon and many other stores are now carrying the Boox Tab Ultra in their inventory. The tablet and the stylus are included in the package, which can be purchased for the official price of $599. The keyboard case can be purchased separately for $109.
Final Words
At $600, the Boox Tab Ultra is expensive, and when you add the $110 keyboard case, it costs $710. We are interested in a very particular use case. The Boox Tab Ultra is the right device for you if you want an e-ink screen that is more than just an e-reader and can also be used to browse the web, read online articles, and write blogs. With extra features like reading and drawing, it could replace your Kindle and tablet if you don’t use the latter to watch videos or read books.
