A phone already takes up a valuable pocket. XTEINK’s answer to carrying an e-reader is to put one on the back of it. The XTEINK X3 is a 58-gram E Ink reader that attaches to compatible magnetic phone setups, giving an ebook a place alongside something most people carry anyway. It is a slightly odd idea until you picture the alternatives: another device loose in a bag, or a book left at home because there wasn’t room. The X3 will be offered for $55 during its November 13–15 Black Friday Early Access period, bringing this unusual little reader into the holiday shopping conversation.
The XTEINK X3 measures 97.6 × 63.7 × 5.1 mm, with a 3.7-inch screen and a body small enough to sit across the palm of a hand. Its magnetic backplate works with compatible accessories, and two adhesive metal rings come in the box for additional mounting arrangements. You can detach the reader whenever you want to use it; the magnetic system is primarily a way to bring it along. That’s an important distinction. No one needs to read a novel while holding a phone and a second screen together. The appeal is being able to leave home with a book without having to remember to pack one separately.
Once the X3 is in hand, its controls make more sense than they might in a product photo. Physical buttons turn the pages, and a built-in motion sensor lets readers advance with a gentle movement of the device. With so little body to grip, not having to reach across the display is useful. Someone standing on a bus could hold a handrail with one hand and keep reading with the other. At a café, a reader could set a drink down and pick up a story without unlocking a phone or sorting through apps. These aren’t dramatic new uses for technology. They’re ordinary moments in which a simple control matters.
The tiny screen is also the X3’s biggest compromise. Its 259 PPI E Ink panel keeps letters detailed within a limited display area and has the low-glare appearance of electronic paper. But a 3.7-inch screen means more frequent page turns, particularly at larger font sizes. There is no touchscreen or built-in front light, either, so menus are handled with buttons and reading in a dark room calls for an external light. Those details make the X3 a more natural fit for novels, short stories and essays than for comics, technical PDFs or heavily illustrated books. Its portability is easy to appreciate; whether its screen feels comfortable depends on what you read.
Getting books onto the device requires a little involvement. The X3 supports EPUB and TXT files and can receive content through XTEINK’s companion app or a microSD card. A 16GB card comes included, with expansion supported up to 256GB. Readers with a collection of DRM-free ebooks can choose what to keep on the device and organize it themselves. Those who buy books from a store that locks files to its own reading system should check compatibility first. Once compatible titles are stored locally, they remain available without a constant internet connection. For some people, that small amount of file management will be second nature; others may prefer a more integrated bookstore experience.
A 650mAh battery powers the reader, which charges through a magnetic pogo-pin connection. XTEINK’s specifications describe multi-day use under light reading conditions, although battery life will vary. The device can also show a clock or a personal image when a book isn’t open, and it includes NFC support for certain compatible unencrypted access cards. Those extras are curious additions to something designed mainly for reading. They give the hardware a little character, but they aren’t the reason to buy it. What matters is whether a pocket e-reader this small makes you more likely to carry your current book through a normal day.
For Black Friday, the details are straightforward. The XTEINK X3 will be priced at $55 on the brand’s US website during Black Friday Early Access from November 13 through November 15. XTEINK’s broader Black Friday campaign is scheduled for November 19–30, with other devices and accessories also featured. Shoppers should check the official product page for stock and shipping information before ordering. You can also check out the Black Friday deals on Amazon.
A $55 mini reader that can ride on the back of a phone is a distinctive gift idea, but it won’t suit every reader. If you need a large display, built-in lighting or effortless access to a locked ebook library, the X3’s smallness may feel restrictive. If you already own compatible books and like the thought of having one with you during the short gaps in a day, its magnetic design starts to look genuinely useful. The next time you’re packing light, there might be room for one more book after all.
