Xteink has unveiled its latest e-reader, the X4, featuring a built-in magnetic system that securely attaches to the back of an Apple iPhone. This makes the device highly portable and convenient for use anywhere. The X4 is priced at $69.
Technical specifications highlight its compact design: it weighs just 77 grams and has a slim profile of 5.9 mm. The front panel houses a 4.3-inch black-and-white screen with a resolution of 220 dpi. Two buttons at the bottom provide simple, clutter-free operation.
Inside, the Xteink X4 packs an ESP32 chip, 16 GB of internal storage, and a 650 mAh battery that delivers up to two weeks of battery life under normal use. This combination makes it well-suited for reading, note-taking, and other text-based tasks on the go.
With its magnetic attachment and compact size, the X4 is easy to carry alongside an iPhone, effectively turning the smartphone into a dedicated reading companion. The e-ink technology reduces eye strain and ensures readability even in bright daylight.
