Xteink X4 E-Reader: A Pocket-Sized Device With Big Potential and Frustrations

Daily Technology

02/02/2026

The Xteink X4 e-reader aims to be the ultimate pocket-friendly device for book lovers, boasting an incredibly small form factor. However, its diminutive size comes with a steep learning curve and a host of limitations that may deter some users. Despite its initial drawbacks, a burgeoning community is working to unlock its full potential.

Key Takeaways

The Xteink X4 is exceptionally small, even smaller than previous compact e-readers.
Its MagSafe integration with smartphones is problematic due to magnet placement.
The device lacks a touchscreen, has unlabeled buttons, and a confusing UI.
Limited file support and difficult file transfer methods add to the frustration.
An active community is developing alternative firmware to improve usability.

Unmatched Portability, Unsettling Design

The Xteink X4 stands out for its remarkable size, measuring even smaller than the once-lauded Kobo Mini. Its 4.3-inch E Ink screen is encased in slim bezels, making it a truly pocketable device. However, the initial excitement over its size quickly fades when encountering its design flaws. The advertised MagSafe feature, intended to attach the e-reader to the back of a smartphone, proves difficult to align correctly on newer iPhone models, often leaving the device unusable or awkwardly positioned.

Navigating the Frustrations

At $69, the X4 is one of the most affordable e-readers available, but this price point necessitates compromises. The 4.3-inch E Ink screen, while adequate for reading, has a lower resolution (220ppi) compared to modern Kindle and Kobo devices, resulting in slightly jagged text. Crucially, there is no built-in screen lighting, requiring an external light source for reading in dim conditions. The absence of a touchscreen is perhaps the most significant hurdle. Instead, users must rely on a series of unlabeled buttons on the device's edge and below the screen. The functionality of these buttons changes depending on the context within the user interface, leading to frequent incorrect presses and a steep learning curve.

Limited Functionality and File Transfer Woes

Unlike more advanced E Ink devices that run Android, the X4 is strictly for reading, supporting only TXT and EPUB files, along with basic image formats. There is no integrated bookstore, meaning users must source their own DRM-free ebooks. Transferring these files to the X4 is also a cumbersome process. The device does not mount as a storage device when connected to a computer, and the Wi-Fi file transfer feature is either still in development or barely functional. The primary method involves using a microSD card, but the card slot is recessed, making insertion and removal difficult without tools.

Community-Driven Improvements

While Xteink has released some software updates, the pace of improvement has been slow. However, the company's decision not to lock down the device has fostered a dedicated community. Users are developing and sharing alternative firmware, such as CrossPoint Reader, which significantly enhances the X4's usability. This open-source firmware simplifies the UI, adds on-screen labels for buttons, and expands customization options for ebook display. The ease with which this alternative firmware can be installed and uninstalled makes it a compelling reason to consider the X4.

A Niche Device for the Tinkerer

The Xteink X4 is unlikely to replace a feature-rich e-reader like a Kobo Libra 2 for most users. The lack of a touchscreen, backlighting, and a robust user interface are significant drawbacks. However, for those who prioritize extreme portability and are willing to engage with community-developed solutions, the X4 offers a unique and surprisingly compelling experience. It serves as a welcome distraction from smartphones, providing a dedicated reading device that, with a little tinkering, can become a truly enjoyable companion.
