A few months after launching a 10.3 inch E Ink color tablet with pen support, the folks at Onyx have introduced a smaller, cheaper model sporting a 7.8 inch display. Like the Onyx BOOX Tab Ultra C, the new Onyx BOOX Tab Mini C features an E Ink Kaleido  3 display with support for 4,096 colors, a pressure-sensitive pen for writing or drawing on the screen, a Qualcomm octa-core processor, and 4GB of LPDDR4x memory.

But with a smaller screen the new model is a little more portable. And with a $450 price tag, it’s also a little more affordable.

The larger model sells for $600 and in addition to a bigger, higher-resolution display (that’s a bit closer to the size of an A4 sheet of paper), that model has twice as much built-in storage plus a 16MP rear camera.

But otherwise, the two eReaders/eNotes are pretty similar. Both can display 300 pixels per inch of black and white content or 150 pixels per inch of color content. Both use E Ink’s Kaleido 3 display technology, which puts a color filter on top of a greyscale display to add support for some color… but expect colors to look a bit dull compared with a typical LCD or OLED display. And because E Ink screens typically have slow refresh rates, these device are really designed for reading static content rather than for watching videos or playing high-motion games.

Other features include a front-light with support for adjustable color temperature, support for WiFi and Bluetooth, stereo speakers, a built-in microphone, a 5,000 mAh battery, a G-sensor for automatic screen rotation, and a USB Type-C OTG port for power and/or data.

The Onyx BOOX Tab Mini C runs an Android 11-based operating system that’s optimized for E Ink displays. There’s native support for documents in a wide range of formats document, ebook, image, and audio formats.

  1. After viewing promotional video it seems Internet light is on all time. What is the point of an e-ink display if you need internal light all time on?

    On a black & white e-ink display you need internal light onlybwhen ambiental lightvis low, but not when on other cases.
