The Xteink X4 Pro could be the tiny e-reader of your dreams

The Xteink X4 Pro, a compact e-reader designed for portability and convenience, has emerged as a compelling option for avid readers seeking a lightweight alternative to traditional e-readers. The device, developed by the Chinese hardware manufacturer Xteink, features a touchscreen interface and a front light, two upgrades that address common criticisms of earlier models such as the X3 and X4. These improvements position the X4 Pro as a more practical choice for daily use, particularly for those who prefer reading in low-light conditions or desire a more intuitive navigation experience. The X4 Pro maintains the ultra-portable design that made Xteink's previous e-readers popular among tech-savvy book lovers. Weighing just 72 grams and measuring 5.95 millimeters in thickness, the device is roughly the same size as its predecessor, the X4. Its diminutive form factor allows users to carry it easily in a pocket or attach it magnetically to the back of a smartphone, making it ideal for on-the-go reading. However, unlike the earlier models, the X4 Pro introduces a touchscreen display and a front light, significantly enhancing usability and comfort for extended reading sessions. Users who have tested the X4 Pro report that the new features make the device more versatile. The touchscreen enables smoother page turning through taps on the side of the screen or the use of physical buttons, offering greater control over how the device is held and operated. The inclusion of a front light adds value for nighttime reading, allowing users to enjoy books without relying on ambient lighting. Despite these enhancements, some users noted that the smaller screen size—4.26 inches, can pose challenges when reading texts with complex formatting, such as poetry with line breaks. As a result, some have opted to return to more conventional e-readers for certain types of content. Battery performance remains a notable strength of the X4 Pro. Users have reported that the device retains a substantial amount of power over extended periods, with one reviewer noting that after three weeks of regular use, the battery level remained around 60%. While the front light does consume additional power compared to earlier models, the overall efficiency of the e-ink display ensures that the device remains functional for long stretches without frequent charging. Charging is facilitated through a magnetic pogo connector, a departure from the USB-C port found in the X4 model. Although this change may inconvenience some users accustomed to universal charging standards, others appreciate the streamlined approach for a device that rarely requires frequent top-ups. In terms of connectivity and file management, the X4 Pro supports both Wi-Fi and Bluetooth for transferring content, although the process is described as somewhat cumbersome. Many users find it more efficient to insert a micro SD card and utilize a provided adapter to transfer files from a computer. Additionally, the device runs updated software that offers improved functionality compared to older versions, though it continues to support open-source code modifications, a feature that appeals to technically inclined users. Despite its advantages, the X4 Pro lacks compatibility with major library e-book platforms such as Libby, limiting its appeal to those who rely on public library resources. This omission highlights a gap in the device’s ecosystem, potentially affecting its market reach. Nonetheless, for readers prioritizing portability and enhanced usability, the X4 Pro represents a significant step forward in the evolution of compact e-readers.
