Pocket-sized e-readers often struggle to balance portability with practical functionality. Xteink is addressing this ongoing challenge with the launch of the X4 Pro. The updated device builds on the cult success of its predecessor by adding an adjustable warm-to-cool frontlight. This highly requested feature eliminates the need for external clip-on lamps and allows users to read comfortably in low-light environments. The $99 USD gadget maintains a strict focus on distraction-free reading while introducing modern updates to a minimalist form factor.
A new touchscreen layer provides a modernized navigation experience for those who prefer tapping and swiping. Purists do not need to worry about losing tactile feedback because the brand kept the physical page-turn buttons along the sides. The front navigation keys from the previous model have been swapped out for a sleek capacitive home button located below the screen. Powering the system is a massively upgraded 1,100mAh battery that delivers roughly 14 days of reading time per charge. Users can store their libraries on the included 16GB microSD card or expand capacity up to 256GB.
The hardware redesign brings notable trade-offs alongside its enhancements. The universal USB-C port is gone entirely. Xteink replaced it with a proprietary pogo-pin magnetic connector to achieve the ultra-thin 5.95mm profile. This change requires carrying a specific charging cable but allows the 72-gram reader to snap securely to the back of compatible smartphones. On the software side the device runs an unlocked developer operating system free of third-party restrictions. The interface supports direct wireless file transfers via the Vision companion app where users can also sync weather updates and daily reading schedules.
The new release refuses to compete with full-featured Android tablets or oversized Kindles. It remains a dedicated tool for consuming DRM-free text in a remarkably compact package. Current owners who rarely read in the dark might stick with the older model. Those who have been holding out for built-in illumination finally have a compelling reason to upgrade to the latest iteration of this niche reading companion.
