TLDR
The Xteink X3 is a compact, button-operated E-Ink reader designed to make short reading sessions practical while commuting or carrying a phone. At 58g and 5.1mm thick, it offers a 3.7-inch 259 PPI display, 16GB microSD storage expandable to 256GB, magnetic phone attachment, shake-to-turn navigation, and unencrypted NFC-card simulation for legal personal use. Its trade-offs are explicit: no touchscreen, no front light, official-app-only compatibility, and warranty exclusions for unofficial firmware or SDK modifications.
Key Takeaways
- Pocket-focused hardware: The X3 measures 97.6 × 63.7 × 5.1 mm, weighs 58g, and uses a 3.7-inch, 259 PPI glare-free E-Ink display.
- Controls and attachment: Page turning is handled through dedicated physical buttons or a gyroscope-based shake gesture; a magnetic backplate enables attachment to a phone.
- Storage and formats: It includes a 16GB microSD card and supports storage expansion up to 256GB. Supported document formats are EPUB and TXT; images include JPG and BMP.
- Battery and connectivity: The 650mAh battery is rated for up to 10–14 days based on 1–3 hours of reading daily; connectivity includes 2.4GHz Wi‑Fi and Bluetooth.
- Constraints and support: X3 has no touchscreen or front light, works only with the Xteink official app rather than third-party apps, and carries a 30-day return policy plus one-year warranty. Unofficial firmware and SDK modifications are not warranty-covered.
