    The Onyx Boox Kon-Tiki 3 is a versatile 7.8-inch e-reader featuring a high-resolution E Ink Carta Plus display (300 ppi, 1872 x 1404) and a flicker-free Moon Light 2 frontlit system with adjustable color temperature. Powered by an 8-core 2 GHz processor, 3GB of RAM, and 32GB of internal storage, it runs on Android 11, allowing for extensive third-party app support and a smooth reading experience for over 20 file formats.
