Overview
- Xteink put the X4 Pro on sale through its online store for $99, which launched Tuesday and keeps the company’s tiny, pocketable 4.26‑inch form factor.
- The Pro adds an adjustable warm‑to‑cool frontlight and a touchscreen while retaining side physical page‑turn buttons to address complaints about dim‑light reading and clumsy button navigation.
- Xteink removed a native USB‑C port in favor of a magnetic pogo‑pin charging connector and includes an adapter, a change reviewers say trades universal charging convenience for a slimmer design.
- Out of the box the device accepts only DRM‑free text‑only PDF and MOBI files plus JPG/BMP images, which prevents direct use of most library loans and Amazon‑protected ebooks.
- Reviewers report strong battery life of multiple weeks with light use but note uneven lighting, occasional software glitches, some weak phone magnet attachments, and that CrossPoint Reader alternative firmware will be available at launch to improve the UI and reading experience.
