Onyx electronic book reader with color display

Onyx has opened pre-orders for the BOOX Tab Ultra C Pro in the US, less than two weeks after the official launch of this 10.3-inch e-reader, which is actually a tablet with e-ink technology. BOOX Tab Ultra C Pro upgrades BOOX Tab Ultra C. However, for some unknown reason, Onyx preinstalled Android 12 on BOOX Tab Ultra C Pro and not the newer Android 13 and 14 systems.

In addition, the BOOX Tab Ultra C Pro features the newer UFS 3.1 flash memory, which should provide significantly higher read and write speeds than the UFS 2.1 found in its predecessor. The Onyx continues to include 128GB of storage, but now offers 6GB of LPDDR4X RAM instead of 4GB. In addition, the BOOX Tab Ultra C Pro has a more powerful octa-core processor with a 40 percent higher maximum clock speed, which, along with the additional RAM, should provide a faster user experience.

Surprisingly, Onyx has installed a 4600 mAh battery in the BOOX Tab Ultra C Pro, which is 27 percent lower capacity compared to the 6300 mAh cell in the BOOX Tab Ultra C. The BOOX Tab Ultra C Pro sells for around $650 – with a free magnetic protective case, stylus, and replacement stylus tips. The reader also has the option to attach a magnetic keyboard, which is sold separately. You have to pay an additional $150 for it. The keyboard is 5-row and has a built-in touchpad.
