Xteink<\/a><\/p>\n<\/p>\nThe 220 ppi e\u2011ink display is not as sharp as a Paperwhite, but it is perfectly fine for text at this size. There is no touchscreen and no frontlight, just physical page turn buttons and a power key, so it behaves more like a tiny paperback than a gadget. You need ambient light to read, but in return, you get a very focused, distraction-free surface that does not glow or buzz at you.<\/p>\n<\/p>\n
The internals are minimal: an ESP32 processor, 128 megabytes of RAM, and a bundled 32GB microSD card with support up to 512GB. The 650mAh battery lasts up to fourteen days with one to three hours of reading per day. It charges over USB-C and connects via 2.4GHz Wi\u2011Fi and Bluetooth for file transfers, so you can grab books wirelessly or just swap the microSD card.<\/p>\n<\/p>\n
The X4 only supports EPUB and TXT for documents, plus JPG and BMP for images, and does not run third-party apps or connect to any bookstore. You sideload everything, either over Wi\u2011Fi or by copying files to the card. For people tied to Kindle or Google Play, this is a hurdle, but for readers with DRM-free libraries, it feels refreshingly simple and vendor-neutral, just you and your files.<\/p>\n<\/p>\n
Xteink markets it as \u201cMore Than a Reader,\u201d suggesting you use the X4 as a digital business card, a tiny calendar, a film production workflow board, or a reference screen for notes and checklists. Because it displays static images and text, it doubles as a little always-on panel you can stick to a monitor, fridge, or phone, not just a book page. The magnetic back makes those experiments feel natural and reversible.<\/p>\n<\/p>\n
The X4 is really for minimalists, tinkerers, and people who like the idea of a dedicated reading screen that goes everywhere their phone does. It is quirky, with no light, no touch, and no store, but those constraints are the point. It is a tiny reminder to read instead of scroll, thin enough to forget until you need a page instead of a feed, and cheap enough at $69 that the experiment feels worth trying even if you already own a proper eReader gathering dust at home.<\/p>\n<\/p>\n
