The XTEINK X4 Is the Tiny E-Ink Reader That Makes More Sense Than It Should
The XTEINK X4 is a tiny 4.3-inch e-ink reader that leans hard into pocketability, distraction-free reading, and the kind of low-friction carry that makes you more likely to actually read
Quick Take
- The X4 is interesting because it is small enough to carry like a phone but focused enough to keep you off your phone.
- It is not a Kindle replacement for everyone, but it is one of the easiest impulse buys in e-readers if you want something cheap, tiny, and dedicated to reading.
The XTEINK X4 sounds silly until you grasp its appeal: a 4.3-inch pocket e-reader with physical page-turn buttons, a paper-like screen, and none of the distractions of a phone.
This explains the X4's sudden popularity. Tiny e-readers are having a moment in 2026, fitting phone-like carry habits without phone-like behavior. Esquire called pocket-sized e-readers a rising category this spring, and TechRadar reported the X4 broke into Amazon's e-reader charts after going viral.
Why the X4 is getting so much attention
Its appeal is clear. You get a dedicated reading screen that weighs just 77g, slips into a pocket, and lasts far longer than a phone. XTEINK states the X4 has a 4.3-inch 220 PPI e-ink display, 16GB of included storage (expandable up to 256GB via microSD), and battery life rated up to 14 days based on light daily reading.
More importantly, it removes friction. A normal e-reader can still feel like another thing to pack. The X4 feels like an always-with-you gadget, which is why smaller e-readers are catching on.
What makes it appealing
The X4 seems the better pick for most people over the smaller X3. It offers more reading room without losing the pocket-reader concept. That extra screen size matters on a device this small.
Its other appeal: it knows what it is. No touchscreen, no front light, no third-party app support. On paper, that sounds limiting. In practice, it is part of the charm. The X4 appeals for the same reason a cheap Casio does. It does one thing, is hard to overcomplicate, and feels oddly refreshing.
What you give up
This is still a niche device. If you want your main e-reader for long couch sessions, night reading without a lamp, or a polished bookstore ecosystem, a Kindle or Kobo still makes more sense.
That is the tradeoff. The X4 is not a better all-around e-reader than a full-size Kindle Paperwhite. It is a better carry-everywhere reading gadget if your current reader stays home while your phone comes everywhere.
Should you buy it?
If you want a tiny e-reader to read more in short bursts, this is the XTEINK to start with. It is the most approachable version of the idea, and the size-to-usability balance makes more sense than it has any right to.
