Xteink - S4 Black Pocket eReader

The unisex Xteink S4 pocket eReader in Black is an ultra-compact reading device designed to offer the flexibility of Android in a genuinely pocketable format.

As the successor to the ultra-thin XTEINK X4, the S4 moves from a proprietary Linux-based operating system to an open 32-bit Android 11 platform, allowing users to sideload reading apps such as Kindle, Kobo and KOReader. Its 4.3-inch E Ink touchscreen has a 220 PPI resolution, while the compact frame weighs just 95 grams and measures 6.98 mm thick.

Physical side page-turn buttons and a dedicated front home button preserve the tactile convenience of a traditional eReader, while built-in magnets on the backplate allow the S4 to attach to MagSafe-compatible phone cases. The Space Black finish gives the device a discreet, understated character suited to everyday carry.

Slip the Xteink S4 into a pocket or small bag for commuting, travel and quick reading sessions, or attach it to a MagSafe-compatible phone case for convenient access throughout the day. Its compact size is ideal for portability, while Android support gives readers more freedom to choose their preferred reading platform.
