China-based Xteink is entering the competitive e-reader market with the X4, a new device focusing on extreme portability and unique connectivity features. Priced at $69, the 4.3-inch e-reader aims to challenge established brands like amazon and kobo with its compact size and magnetic attachment capabilities for compatible smartphones.While offering a lower price point, the X4 presents tradeoffs in screen resolution and access to major ebook ecosystems, requiring users to sideload content or rely on DRM-free formats [[1]].
Chinese company Xteink has launched the X4, a remarkably compact e-reader designed for ultimate portability. The device features a 4.3-inch electronic ink display, making it even easier to carry than smaller Kindle or Kobo models. A unique feature allows the e-reader to magnetically attach to the back of an iPhone, Pixel 10, or any device supporting Qi2 or Apple MagSafe wireless charging, mirroring the convenience of a wireless charging power bank. For users without compatible phones, Xteink also offers a magnetic adhesive ring.
Available starting at $69 through Xteink’s online store, the X4 undercuts the pricing of Kindle and Kobo devices, though with some trade-offs in features and functionality. The X4’s e-ink screen has a resolution of 220ppi, lower than the 300ppi found in most modern e-readers, which means text may appear less crisp. Because the screen lacks a built-in backlight, a nearby light source is necessary for comfortable nighttime reading. However, the X4 boasts a 650mAh battery capable of lasting up to 14 days with 1-3 hours of daily use.
One of the primary limitations of purchasing e-readers from smaller brands like Xteink is the lack of access to established ebook stores like Amazon and Kobo, unless the device runs Android with Google Play Store access. The X4 supports only DRM-free EPUB and TXT format ebooks and documents. Users must sideload ebooks onto the device via a microSD card (supporting up to 512GB) or wirelessly transfer them over Wi-Fi.
The X4 does not feature a touchscreen, instead relying on dedicated page-turn buttons – a feature many e-reader enthusiasts appreciate. Users also have the option to install custom fonts if they prefer alternatives to the pre-installed options.
