Onyx Boox tablets are what Amazon's Kindle e-readers could only dream of being. Equipped with the Google Play Store, native OCR, stylus support, and a wide range of features found in full-fledged Android tablets, Boox's E Ink devices are spectacular. The Boox Note Air 4 C used to be the best E Ink tablet from Onyx Boox, and the best all-around e-paper tablet period. It was succeeded by the Note Air 5 C in October 2025, and I have been testing it for about a month now.
The Onyx Boox Note Air 5 C adds iterative upgrades to the Onyx Boox Note Air 4 C. However, the result is a polished product that performs smoother than ever before, is just as light as ever, and retains all the features that I love about Onyx Boox's Android e-paper tablets.
