Tiny e-reader snaps to phone with new upgrades
22 Jul
Summary
- Xteink X4 Pro adds adjustable-warmth backlight.
- New model features a larger 1,100mAh battery.
- Device uses pogo-pin charging, not USB-C.
Xteink has released the X4 Pro, an enhanced iteration of its viral, ultra-portable e-reader designed to magnetically attach to smartphones. Priced at $109, this upgraded device addresses key limitations of its predecessor. A significant addition is the adjustable-warmth backlight, making it usable in any lighting condition, a feature notably absent in the earlier X4 model.
The X4 Pro also incorporates a substantial battery upgrade, increasing capacity from 650mAh to 1,100mAh for extended reading sessions. While maintaining its compact 4.3-inch screen size and 72g weight, the new model now includes a touchscreen interface. However, Xteink has opted for a pogo-pin charging port instead of the industry-standard USB-C, which may inconvenience users seeking universal charging solutions.
Furthermore, the X4 Pro's e-reading capabilities fall short of current standards, with a screen resolution of 219 ppi compared to competitors' 300 ppi. While Xteink claims software improvements, its user experience may still lag behind more established e-readers. Despite these drawbacks, the X4 Pro occupies a unique niche with its extremely small form factor and sub-$100 price point, offering a distinct alternative in the e-reader market.
