The Xteink X3 is the ultimate pocket e-reader with one fatal flaw

While the X3 is not quite small enough to fit into a credit card slot, it is impressively compact, slipping into a pocket without adding noticeable bulk. The hardware refinements are evident: the button layout is more intuitive, and the magnetic mount on the back is better positioned. However, the magnets themselves lack the strength required for a secure connection to an iPhone 16 Pro. While the X4 felt like a missed opportunity for a MagSafe-style accessory, the X3 performs like a weak handshake, frequently detaching when pulled from a pocket.

The 3.7-inch E Ink display offers a crisp 250ppi, but the software remains a hurdle for anyone accustomed to the polished experience of a Kindle or Kobo. Navigation is often frustrating, and while the addition of contextual labels on the homescreen is a welcome change, they disappear in other menus. For power users, the saving grace is the now-compatible CrossPoint Reader firmware, which can be installed via a computer to bypass some of the stock OS limitations.

Ultimately, the X3 is a device that demands compromise. It is a joy to carry and read, yet the reliance on a proprietary charging cable in an era of USB-C standardization is a difficult pill to swallow. Replacement cables are not yet widely available, and the risk of losing the unique charger makes this otherwise charming, ultra-portable reader a difficult recommendation for the average user.
