Xteink X4 Pro E-Reader Features Dual-Tone Frontlight

Xteink released the X4 Pro, a $99 pocket-sized e-reader, on an unspecified recent date, introducing an adjustable warm-to-cool frontlight and a touchscreen interface. This 72-gram device features a 4.3-inch E-Ink display with 220 PPI and a 1,100mAh battery, maintaining a slim 5.95mm profile. The frontlight feature aims to provide comfortable reading in low-light conditions without external lamps. The X4 Pro retains physical page-turn buttons while incorporating a capacitive home button and a touchscreen for navigation. The device comes with 16GB of internal storage, expandable up to 256GB via microSD card. A significant design change involves the replacement of the universal USB-C port with a proprietary pogo-pin magnetic connector for charging and data transfer. This allows the e-reader to magnetically attach to compatible smartphones, a feature designed to enhance portability and integration. The 1,100mAh battery is rated to provide approximately 14 days of reading time on a single charge. The X4 Pro's design prioritizes a minimalist form factor and distraction-free reading experience, building upon the success of its predecessor.
