An e-book reader as light as a set of keys and thinner than a pencil: With the XTEINK X3, the XTEINK brand aims to take reading to places where bulky tablets and heavy e-readers have long since given up. It fits in a shirt pocket, a pencil case, and attaches magnetically to the back of an iPhone. We took a closer look at this compact E Ink reader when it launched in August.
There’s that moment almost everyone knows: a five-minute wait at the bus stop, ten minutes in line, half an hour on the train. Almost automatically, your hand reaches for your smartphone—and “just a quick look” turns into thirty minutes of endless scrolling. This is exactly where the XTEINK X3 comes in. Instead of yet another screen full of notifications, you get a device that can do just one thing—but does it really well: reading.
Why get a dedicated e-reader at all—instead of just using your cell phone?
It’s a valid question. After all, smartphones and tablets can display books too. The difference lies in the details. An E-Ink display uses electronic ink instead of a backlit LCD. The image looks like printed paper, doesn’t flicker, and remains easy to read even in the blazing summer sun. This is much easier on the eyes than a traditional cell phone screen, and because E-Ink only uses power when you turn the page, the battery lasts for days instead of just hours.
The second, often underestimated advantage is psychological: A dedicated e-reader has no push notifications, no short videos, and no red notification counters. What may sound like a sacrifice is actually a relief to many readers. The X3 is therefore less of a gadget and more of a deliberate alternative to constant swiping.
Ultra-light: 58 grams you won’t even notice
The first thing you notice about the XTEINK X3 is what’s missing: weight. Weighing just 58 grams and measuring only 5.1 millimeters thick (dimensions: 97.6 × 63.7 × 5.1 mm), the e-reader is one of the most compact devices of its kind. The 3.7-inch display makes it barely larger than a check card. It slips into a shirt pocket, a pencil case, or the side pocket of a backpack without you even noticing it.
For students who are already lugging around laptops, chargers, and notebooks at the start of the semester, this is a real selling point. The “mobile library” weighs less than a paperback but can hold thousands of e-books, manga, and documents. For anyone who hasn’t been reading simply out of laziness, the X3 takes away that last excuse.
At a glance:
- 3.7-inch E-Ink display with 259 PPI—crisp, paper-like display
- Weighs 58 g, 5.1 mm thin – comfortable one-handed use
- 16 GB of internal storage, expandable up to 256 GB via microSD
- Battery life of up to 10–14 days with 1–3 hours of reading per day (650 mAh)
- Supported formats: EPUB, TXT, JPG, BMP
- Magnetically attaches to the iPhone: Two screens, one simple step
Perhaps the cleverest detail is on the back. The X3 features a built-in magnetic ring that’s compatible with Apple MagSafe. No additional adhesive ring is needed for compatible iPhones. The e-reader snaps securely onto the back of the smartphone, effectively turning it into a dual-screen device: the phone on the front for messages and everyday use, and the quiet E Ink screen on the back for reading.
The switch happens in a single motion: “Snap. Attach. Read.” If you want, you can also attach one of the included magnetic rings to other devices, such as a small notebook or a power bank. In the English-speaking tech community, this very magnetic approach became a cult favorite with the previous model; sites like Boing Boing and The Verge have reported on it extensively. The X3 refines the concept with an optimized magnet design for broader smartphone compatibility.
Digital Detox: A Closed System to Combat Distractions
The third major pillar is conscious reduction. The XTEINK X3 relies on a closed reading system with no app store, no browser, and no social media pop-ups. “No Ads. No Pop-ups. Just Focus.”—this motto describes the experience quite aptly.
Anyone who’s ever tried to study for an exam while a notification flashes up every few minutes knows the problem. The X3 consistently blocks out these distractions. Books are transferred to the device via the proprietary app from your smartphone or directly from your PC, and after that, it’s quiet. The anti-glare E-Ink display remains clear even outdoors—on the grass in the park or in a café in the sun.
The fact that it operates without a touchscreen is intentional: You turn pages using the gyroscope (a light shake) or the physical buttons on the side. That might sound unconventional, but it works surprisingly intuitively with one hand—whether you’re standing on the subway or relaxing on the sofa.
Who will benefit from the XTEINK X3?
Commuters can turn their bus and train rides into real reading time instead of scrolling through their phones. Students and learners can carry lecture notes and academic texts without the added weight and read with focus, free from digital distractions. Frequent travelers benefit from the minimal weight and long battery life—an entire library in their carry-on, without any extra weight. And bookworms seeking a pure, uninterrupted reading experience get exactly that: a device that wants nothing more than to let them read.
The X3 is thus clearly aimed at people between the ages of 18 and 45 who value a minimalist lifestyle, efficient learning, and intentional screen breaks—and who aren’t looking for yet another multifunctional device, but rather a specialized one.

Small Extras with a Big Impact
Beyond just reading, the home screen can be customized with photos, a clock, and widgets—turning the reader into a personalized display.

And for those who value privacy: According to the manufacturer, all data is processed locally on the device and is not uploaded to the cloud.
A detail for tech enthusiasts: Devices purchased directly from the official XTEINK store come with open, unrestricted firmware—free from third-party restrictions. For tinkerers and “tech geeks,” the X3 is therefore also a playground.
