Launched September 6, 2026
Xteink X4 Classic
The X4, refined. Also called the X4 V2. 68 g, no USB-C.
The button-only successor to the discontinued X4: same 4.3-inch panel, but 68 g (down from 77 g), 4.9 mm thick, and a 920 mAh battery on a new ESP32-S3 chip. Charges over pogo-pin with an included adapter, not USB-C. Adds a customizable e-ink back screen and a shake-to-flip page-turn gesture. Officially also called the X4 V2 — not to be confused with this site's X4 Pro, which used that name earlier. Launched September 6, 2026; CrossPoint and other third-party firmware do not run on it yet.
