Xteink Launches $99 X4 Pro E-Reader with Phone-Mounting Magnets and Touchscreen

Xteink launched the X4 Pro e-reader on July 21, 2026, priced at $99. The 4.26-inch E Ink device adds a touchscreen and front lighting absent from earlier models. Embedded rear magnets and a pogo-pin connector pair it with compatible smartphones as a companion screen. A microSD slot and planned third-party CrossPoint firmware round out the open-hardware pitch.
