It charges via pogo pins rather than USB-C and weighs just 72 grams. Notably, all units sold through the official website ship with unlocked firmware, allowing third-party firmware installation. Xteink has become an official partner of the CrossPoint Reader open-source firmware project, which already supports previous Xteink models and other ESP32-based e-readers. The X4 Pro will be officially supported by CrossPoint Reader once it begins shipping, currently scheduled for August 2, 2026. ## Full article daily.dev links to this article rather than hosting it.
