The Xteink X3 is a compact e-reader that launched in 2026 and was built by Chinese startup Xteink, featuring a magnetic design that snaps to an iPhone’s MagSafe ring and a choice of 3.7-inch or 4.3-inch E Ink displays. The device weighed 58 grams and focused on hardware navigation, with physical page-turn buttons and no touchscreen. It shipped with a 16GB microSD card preinstalled.
Design emphasized minimalism with frosted white and black finishes, rounded bezels and a row of navigation keys for one-handed use. Battery life was rated at 10–14 days with moderate daily reading, and accessories included magnetic stick-on rings for non‑MagSafe phones and a $9.99 clip-on reading light. Charging used a proprietary Pogo Pin cable.
For readers, the X3 turned wasted phone backspace into a dedicated reading surface that prioritized portability over resolution and front light. Priced at $79, it reframed MagSafe as a platform for focused, low‑distraction content consumption and signaled new directions for snap-on phone peripherals.
