The eReader that goes wherever your phone goes. The Xteink X4 solves the reason most people buy a Kindle and stop using it: the device stays home. At 74 grams and 4.9mm thin — smaller than a deck of cards — the X4 magnetically snaps to the back of your iPhone or Android phone via MagSafe, Qi2, or the included adhesive magnetic rings, turning your phone into a dual-screen reading machine. When the phone comes out of your pocket, the X4 comes with it.

The magnetic back is the X4's defining innovation. Unlike a Kindle that lives in a bag or on a bedside table, the X4 lives on your phone — snapped flat against the back, adding barely any thickness and negligible weight. When you have a moment — a commute, a waiting room, a lunch break, a few minutes before sleep — you flip the X4 open and start reading in one second, not the thirty-second ritual of unlocking a separate device and re-engaging with a screen competing for your attention.

The 4.3-inch E Ink display at 220 PPI delivers sharp, paper-like text that is genuinely comfortable for extended reading sessions — no backlight glare, no blue light, and fully readable in the UAE's bright outdoor sunlight where phone screens reflect and wash out. Note: the X4 has no built-in front light and is best used in natural light or with an external reading light. Battery life reaches up to 14 days on a single charge based on 1–3 hours of reading per day, charged via USB-C.

Physical page-turn buttons are the correct input for dedicated reading. Unlike a touchscreen that invites accidental taps and the temptation of a full interface, the X4's physical buttons keep interaction to a single purpose: forward, back, confirm. No distractions, no mode-switching — just text advancing at the press of a button.

16GB internal storage holds thousands of EPUB and TXT books. The included microSD slot expands storage further for larger libraries. Books transfer via microSD card, Wi-Fi hotspot, or the Xteink app. Supports EPUB, TXT, BMP, and JPG, with automatic conversion of MOBI and PDF via the app.

The X4 is not trying to be a Kindle Paperwhite — it is something different. It is the eReader for people who know they should read more, own a Kindle gathering dust, and need the device to be in the same place they already are: in their pocket, on their phone, always within reach. For UAE commuters on the Metro, readers in coffee shops, travellers at airport gates, and anyone who wants to replace a scrolling habit with a reading habit, the X4 is the most practical eReader format ever produced.
