Chinese hardware manufacturer Xteink has officially launched the Xteink X4 Pro, a refined, ultra-portable e-reader designed to address the most requested features from its community: a responsive touchscreen and a built-in front light. Available now for $99 exclusively on the company’s website, the device aims to bridge the gap between niche novelty hardware and a daily-driver reading companion.
The Evolution of Pocket-Sized Reading
Xteink’s tiny e-readers have gone viral on social media by offering a distraction-free alternative to smartphone scrolling. While previous models like the X3 (currently discounted at Amazon) and the slightly larger X4 carved out a cult following, they were hampered by clunky, button-only navigation. The X4 Pro maintains the impressive form factor—weighing just 72 grams and measuring 5.95 mm thin—while finally adding the modern interface components users demanded.
Nighttime Reading and Ergonomics
The addition of the front light makes the X4 Pro a legitimate contender for bedtime reading. During testing, the device performed well with the light set to a warm, dim setting. However, due to its compact 4.26-inch display, it remains better suited for prose than complex formatting like poetry, where line breaks can become problematic. Its small size mimics the feel of a smartphone, offering an experience that is both convenient and surprisingly immersive, allowing for page turns via both touch and physical side buttons.
Battery Life and Connectivity
The X4 Pro maintains the stellar battery efficiency typical of e-ink devices, lasting weeks on a single charge despite the power demands of the new front light. A notable hardware shift is the move from USB-C to a magnetic pogo charger. While this may frustrate those who prefer universal charging cables, the infrequent need to charge the device mitigates the inconvenience. File management remains a bit manual; while Wi-Fi and Bluetooth transfers are supported, many users will likely find it faster to simply use the included micro SD to USB adapter to side-load files.
Compatibility Limitations
Prospective buyers should be aware that the Xteink ecosystem is not as open as mainstream tablets. The device does not support library integration apps like Libby due to DRM-protected files. Furthermore, it remains walled off from Amazon’s ecosystem; despite purchasing books from Amazon, you cannot read them on the X4 Pro. However, for those who own their own .epub files, the device offers a seamless and highly portable reading experience.
