Xteink X4 Pro e-reader adds a built-in front light; tiny pocket-sized device could almost replace your Kindle

The new Xteink X4 Pro e-reader, priced at $99, features a built-in front light, touchscreen, and compact design, making it a potential alternative to Kindle. Weighing just 72 grams and measuring 5.95mm thick, it offers 16GB storage, expandable to 256GB, and a 1,100mAh battery.

CuriousCats Full Story

The Xteink X4 Pro, an innovative e-reader, combines portability with functionality, featuring a 4.3-inch touchscreen and an adjustable built-in front light for nighttime reading. Weighing just 72 grams and measuring 5.95mm thick, it is designed for on-the-go users.12

Priced at $99, the X4 Pro is a strong competitor to basic Kindle models. It offers 16GB of built-in storage, expandable to 256GB via microSD, and a 1,100mAh battery that outperforms its predecessors. However, it lacks a USB-C port, using a magnetic pogo charger instead.46

The device supports DRM-free ebooks and allows users to read epub and mobi files. Despite its compact size, the screen resolution maxes out at 219 ppi, lower than the 300 ppi of basic Kindles, which may affect reading quality. “The addition of the touchscreen and front light makes the Xteink X4 Pro more viable as a device that you can use as your main e-reader,” noted a reviewer.78

While the X4 Pro has improved software, it still may not match the user-friendliness of Kindle or Kobo devices. “Xteink's software has been finicky at best in the past,” a source commented. Nonetheless, its pocketable design and magnetic attachment feature make it a unique offering in the e-reader market, appealing to those seeking a lightweight reading solution.

Key Insight
“The X4 Pro weighs only 72 grams and is 5.95mm thick, making it extremely portable, but it lacks a USB-C port and relies on a magnetic pogo charger. It also features a 1,100mAh battery and 16GB of storage expandable via microSD, though it does not support library e-books like those from Libby.”
