The Xteink X4 Pro Shrinks the E-Reader to Pocket Size

The X4 Pro retains the portability that earned the X3 and X4 their cult following, but addresses the clunky button-based navigation that previously hampered usability. With the addition of a touchscreen and adjustable warm-light settings, the device effectively bridges the gap between a secondary travel accessory and a primary bedtime reader. While its 4.26-inch display remains less than ideal for complex formatting like poetry, the screen provides a comfortable, low-glare alternative to the blue light of a smartphone.

Battery life remains a standout feature, holding at 60% capacity after three weeks of regular use, though users should note the shift to a proprietary magnetic pogo charger instead of the previous USB-C standard. Software updates have improved file management, yet the device still requires manual loading for most content. Because the system lacks integration with services like Libby or Amazon’s ecosystem, it is best suited for users who manage their own libraries of DRM-free .epub files. Priced at $99, the Xteink X4 Pro offers a specialized experience for those prioritizing extreme portability over the convenience of mainstream e-reader platforms.
