Xteink X4 Pro is a pocket-sized e-reader that upgrades the original model with an adjustable warm-to-cool frontlight and a touchscreen interface. Weighing 72 grams, the device features a 4.3-inch 220 PPI E-Ink display, physical page-turn buttons, a capacitive home button, and a 1,100mAh battery that delivers up to 14 days of reading on a single charge. Users can store books on the included 16GB microSD card with support for expansion up to 256GB, while the slim 5.95mm profile maintains the device's compact form factor.
The redesigned e-reader replaces USB-C with a proprietary magnetic pogo-pin connector for charging and data transfer while enabling the device to attach magnetically to compatible smartphones. Running an unlocked operating system, the X4 Pro supports wireless file transfers through the Vision companion app alongside weather updates and reading schedule synchronization.
