It’s not just an e-reader; it’s the "Quiet Space" on the back of your phone.
The Xteink X3 is designed with the philosophy of "Invisibility." It strips away the bulk of traditional e-readers, offering a seamless attachment to your smartphone.
Featherweight Build: Weighing only 58g (approx. 2.0 oz), it’s lighter than most phone cases. You won't feel any extra strain on your wrist during long reading sessions.
Blade-Thin Profile: At just 4.98mm thick, it maintains the sleek silhouette of your phone, fitting easily into tight pockets.
Golden Ratio Layout: The 3.7-inch screen is meticulously sized (98×64mm) to ensure it never blocks your camera lenses or charging ports, regardless of your phone brand.
Minimalist Aesthetics: Available in "Starry Black" and "Mist Grey," featuring a premium matte finish that is both fingerprint-resistant and anti-slip.
Utilizing E-Ink technology, the X3 brings the tactile comfort of physical books into the digital age.
High-Definition Texture: With a 250+ PPI resolution, text remains sharp and crisp, eliminating the "pixelated" look of lower-end devices.
Optimized Refresh Rate: Our self-developed algorithm allows for a full refresh only every 10-20 pages, significantly reducing ghosting while keeping page turns snappy.
Zero Blue Light: As a reflective display, it uses ambient light rather than a backlight. The brighter the sun, the clearer the screen—making it the ultimate tool for outdoor reading.
The X3 isn't just a standalone device; it's a versatile mobile accessory.
Strong Magnetic Grip: Fully compatible with iPhone MagSafe. For Android users, the included "Magnetic Rings" provide the same secure, snap-on experience.
Magnetic Charging: Features an innovative 4-pin Magnetic Pogo Pin port. No more fumbling with USB cables—just snap it on to charge or sync data.
Smart Interactions: Equipped with an NFC chip and a built-in Gyroscope. Shake the device to turn pages, or use it as an elegant E-Ink desk clock/calendar when not in use.
The X3 cuts through the digital noise, creating a sanctuary for your focus.
Distraction-Free OS: A closed, proprietary system with No Ads, No Notifications, and No Pop-ups.
Exceptional Battery Life: A 650mAh battery paired with an ultra-low-power ESP32 chip. One charge can last for weeks of casual reading.
Flexible Storage: Comes with a 16GB TF Card (pre-installed) and supports expansion up to 512GB—enough for a massive personal library.
