Xteink’s X4 Pro is an updated, pocket-sized e-reader focused on reading DRM-free books, building on the company’s earlier X4 line. Multiple outlets report that the main hardware upgrades include a touchscreen and a front light, which add usability features compared with the previous model. Several reviews also describe redesigned controls, including updated buttons, and emphasize that the device is meant to stay compact and portable.
Tech reporting also highlights software and user experience differences versus major e-readers such as Kindle and Kobo. The Verge notes that, despite the hardware improvements, software can be frustrating, implying that the upgrade is not fully frictionless. Other outlets characterize the X4 Pro as a more capable alternative, while still cautioning it may not suit every reader depending on expectations and software performance.
Digital Trends adds that the X4 Pro comes with an unlocked firmware option and an approximately 1,100mAh battery, while How-To Geek notes an accessory-style capability that allows the e-reader to adhere to the back of a phone. Overall coverage frames the X4 Pro as a feature-richer pocket e-reader that improves practical reading, but whose software experience may determine whether it’s a true everyday replacement.
