Xteink X4 Pro Brings a Touchscreen and Front Light to Its Tiny E-Reader

Xteink has unveiled the X4 Pro, the latest version of its ultra-compact e-reader that has gained a loyal following among readers looking for a truly portable alternative to traditional e-book devices. The new model addresses two of the most common requests from users by introducing a touchscreen and an integrated front light, making the device more practical for everyday reading while preserving its wallet-sized design.

The Chinese hardware maker’s earlier X3 and X4 models attracted attention for their remarkably small size. Compact enough to fit in a pocket or wallet, or attach magnetically to the back of a smartphone, the devices were designed to encourage users to read a few pages of a book instead of endlessly scrolling through social media while commuting or waiting in line. However, their button-only navigation made everyday use less intuitive, limiting their appeal despite their innovative form factor.

Touchscreen makes everyday reading much easier.

The addition of a responsive touchscreen significantly improves the X4Pro’s usability. Users can now navigate menus, select books and turn pages with simple taps, while the existing physical side buttons remain available for those who prefer tactile controls. The flexibility allows readers to hold the device comfortably in different positions without sacrificing ease of use.

At just 72 grams and measuring only 5.95 mm thick, the X4 Pro remains almost identical in size to its predecessor. Despite the compact 4.26-inch display, the new model can serve as a primary e-reader for many users rather than simply acting as a secondary companion to larger devices such as the Kindle.

Front light improves night-time reading.

One of the most noticeable upgrades is the built-in front light, allowing the X4 Pro to be used comfortably in low-light environments. The lighting system includes adjustable brightness and colour temperature, making it suitable for evening reading sessions. Although the lowest brightness setting may still feel slightly bright for some readers, the warm lighting option provides a more comfortable experience than reading on a smartphone or tablet before bedtime.

Its compact size also changes the reading experience. Because the display is considerably smaller than conventional e-readers, users naturally hold it closer to their face, creating a feeling that is more similar to using a smartphone. While some readers may worry about this habit before sleep, the e-ink display remains significantly easier on the eyes than a traditional backlit phone screen.

Battery life remains impressive.e

Despite adding a front light, battery performance remains one of the device’s strengths. After several weeks of regular daily use, the battery still retained around 60% charge, highlighting the efficiency of e-ink technology. Although the lighting system consumes additional power compared with previous models, the difference appears minimal during normal use.

One hardware change that may divide users is the charging method. Instead of using a USB-C connector like the earlier X4, the X4 Pro now relies on a magnetic pogo-pin charger. Since the device only requires charging occasionally, the change may not affect many owners. Still, users who prefer carrying a single USB-C cable for all of their devices may find the decision less convenient.

Software improvements and file support

Xteink has also refreshed the software experience, making navigation smoother while continuing to support open-source development for enthusiasts who want to customise the device. Books can be transferred over Wi-Fi or Bluetooth, although the process still requires several steps. For many users, copying files directly to the included microSD card using the bundled USB adapter remains the quickest and simplest option.

Compatibility with digital bookstores is one of the X4 Pro’s main limitations. Unlike mainstream e-readers, the device does not integrate directly with library lending services such as Libby, meaning users cannot easily transfer protected library e-books. However, standard EPUB files purchased directly from publishers can be loaded without difficulty, making the device suitable for readers who maintain their own digital book collections.

A unique e-reader for readers who value portability

Priced at $99, the Xteink X4 Pro offers a distinctive alternative to larger e-readers by combining exceptional portability with meaningful hardware improvements. While the small screen may not suit every type of book, particularly works with complex layouts or poetry, the addition of a touchscreen, front light, improved software and long battery life makes the X4 Pro a much more polished device than its predecessors. For readers who prioritise convenience and want an e-reader they can carry virtually anywhere, Xteink’s latest model delivers a compelling option in a category with very little direct competition.
