Xteink X3: A Pocket-Sized E-Reader with a Catch

The Xteink X3 has emerged as the smallest e-reader on the market, boasting an incredibly compact design. While it improves upon its predecessor, the X4, with refined software and a better magnetic mount, a critical flaw may deter potential buyers.

Design and Portability

Smaller and Lighter

The X3 is a millimeter thinner, a few millimeters narrower, and over half an inch shorter than the X4. Its size is remarkably close to that of a credit card, easily slipping into a pocket without adding noticeable bulk. This extreme portability is the X3’s primary appeal.

Magnetic Mounting Challenges

Xteink initially marketed the X4 with images of it attaching to smartphones via magnets, similar to MagSafe. However, the X3, despite a better fit on devices like the iPhone 16 Pro, suffers from weak magnets that cause it to detach easily. The connection lacks the secure “thunk” found with accessories like PopSockets.

Display and User Experience

Compact Display

The X3 features a 3.7-inch E Ink display with a 250ppi resolution, slightly higher than the X4. The reading experience is comparable, but the small screen size may require smaller font sizes or more frequent page turns. Users who prefer larger fonts may find a larger Kindle or Kobo more suitable.

Improved, Yet Frustrating Interface

Xteink has improved the X3’s button layout and added contextual labels on the home screen. However, these labels disappear when navigating other areas of the operating system. The user interface remains complex and unintuitive, lacking the polish of competitors like Kindle. Software limitations, such as limited font size options, persist.

The Critical Flaw: Charging

Proprietary Magnetic Connection

Instead of a standard USB-C port, the X3 charges via an uncommon magnetic pogo-pin connection. This is a significant drawback, as it requires keeping track of a proprietary cable. The company doesn’t recommend third-party alternatives and will only begin selling replacement cables later this month.

Real-World Inconvenience

During testing, the charging cable was misplaced for three days, highlighting the potential for inconvenience. While the e-reader’s two-week battery life mitigates the issue, the reliance on a proprietary cable feels outdated in a world increasingly standardized around USB-C.

Software Support and Future Potential

CrossPoint Reader Compatibility

The CrossPoint Reader alternative firmware, a popular enhancement for the X4, does not yet support the X3. However, the developer, Dave Allie, reports that X3 support is “basically complete,” though a release date remains uncertain.

Conclusion

Despite its appealing size and software improvements, the Xteink X3’s reliance on a proprietary charging cable is a major drawback. While its portability is undeniable, the inconvenience of managing a unique cable may outweigh its benefits for many users. The X3 is a compelling device for those prioritizing extreme portability, but the charging issue is a significant compromise.
