The Xteink X4 Pro is an ultra-portable ereader designed for distraction-free reading of DRM-free ebooks. Measuring only 5.95mm thick and weighing 72 grams, it's significantly smaller than devices like the Boox Palma 2 Pro and can even attach magnetically to a phone.

Despite its size, the X4 Pro includes page-turn buttons, a circular home button, a touchscreen, and an adjustable front light. Its 4.3-inch display is ideal for text-based reading, offering a focused alternative to smartphones. The device supports importing DRM-free epub and mobi files wirelessly via the Xteink app or USB.

The X4 Pro features a 1,100mAh battery, 16GB of internal storage expandable to 256GB, and a novel magnetic charging adapter due to the lack of a built-in USB-C port. Priced at $99, it competes with basic Kindles but offers superior portability.
