- The Xteink X4 Pro is a pocket-sized e-reader with a 4.26-inch display.
- It features a touchscreen, physical buttons, and a built-in adjustable light.
- Magnets allow it to attach securely to compatible smartphones.

The Xteink X4 Pro is a new, ultra-compact e-reader designed for ultimate portability, measuring just 4.26 inches diagonally. Its E Ink display is significantly smaller than typical six-inch models. This device now includes a touchscreen, complementing its existing physical page-turning buttons for intuitive navigation.
Users can also utilize a new touch-sensitive button for quick returns to the home screen. A built-in light offers adjustable brightness and color temperature, enabling reading in any lighting condition. The X4 Pro comes pre-loaded with CrossPoint Reader software for an improved library management experience.
A notable feature is its magnetic backing, allowing it to attach to compatible smartphones, a stronger connection than previous iterations. Despite a proprietary charging port replacing USB-C, many consider the X4 Pro the best small e-reader available, priced at $84.15, marking its best price to date.
