Review: Xteink X3 is the little e-reader the world’s not quite ready for

An e-reader magneted to the back of a smartphone, just as the prophecy foretold.<br>The market for small e-readers has been booming lately. Earlier this year, Jason took a look at the Xteink X4, a pint-sized reading device that was about as light and small as they come. But those maniacs at Xteink weren’t done yet: they followed it up with the $79 X3, which is unbelievably even lighter and smaller.

I wouldn’t blame you for wondering if there’s such a thing as too small and light—at 3.84 inches by 2.51 inches (and just 0.2 inches thick) the X3 is still larger than, say, a credit card, but not by much. The screen itself measures just 3.7 inches, more than half an inch smaller than the X4’s 4.3 inch, but its 259 ppi resolution still makes it plenty easy to read on.1 At that size it’s little imposition to take it with you wherever you go. Easy to lose? Maybe. Easy to love? Yes.

For one thing, this small size unlocks at least one capability that the X4 couldn’t fully deliver upon—the ability to stick to the back of your phone. Like the X4, the X3 has a MagSafe-compatible magnet in its rear case and it fits just about perfectly on the back of my iPhone 17 Pro, nestled below the camera plateau.

However, the magnet is not particularly strong, and it lacks the secondary stabilizing magnet that you see on official MagSafe accessories, meaning it wobbles around a bit. I wouldn’t call it a super secure connection, but it’s pretty good if you’re just slipping it in and out of a pocket. Just be aware that it probably will come loose.

Like the X4 before it, the X3 features a pair of rocker switches on the front for a total of four possible buttons. But they’ve opted to skip the X4’s side mounted rocker switch in favor of a single buttons on each side. There’s also an on/off switch at the top (plus a recessed button used for resetting the device). And with all of that, they somehow managed to continue to fit a microSD slot in the top. The bottom left corner also has a little set of holes for a lanyard or wrist strap.

The X3 is about the size of just the display on the X4.<br>The one casualty of the smaller X3, however, is the port. The X4 was big enough to accommodate a USB-C connector, but the X3’s thin profile makes that impossible. Instead, there’s a pogo-pin USB cable that connects to four magnetic contacts on the reader. Is this a step back? Strictly speaking, yes. Using a proprietary connector is a bummer in the year 2026, especially because it means having to keep track of a single-use cable. That said, once you get the X3 up and running, the only real need for the connector is charging, and the battery on this thing lasts a very long time. (I’ve yet to run it down in several weeks of usage.) Just remember to make a note of where you stow that cable for the point months down the road when you do need to charge it and find yourself wondering whatever happened to it.

As with the X4, the X3 lacks any sort of screen lighting, meaning that it’s strictly a “read in bright light” device. But don’t worry, because Xteink has already unveiled a new X4 Pro with the company’s first lit screen.2

All in all, I found the X3 very comfortable to read on, whether attached to my iPhone or not. The side buttons work great as page-turners, and the screen is high-contrast and sharp enough to make text render very clearly. All in all, it’s a great reading experience—if you take into account one major caveat.

Soft where?

The elephant in the room for the Xteink X3 is the software. Xteink ships the X3 with its own built-in firmware which, by all accounts, has improved since the first version. But I can’t really tell you, because upon opening the box and powering up the device, the first thing I did was install Crosspoint, the open-source community-built firmware that has turned this device from a curiosity into a real contender.3

Unlike a lot of other firmware replacements, Crosspoint is super easy to install; you can do it right from a web browser. While it’s not fully free of technological hurdles, I’d say that most people comfortable using an e-reader or updating their iPhones will be able to handle the process with few problems. And the benefits are manifold.

Crosspoint is extremely configurable for all your reading needs.<br>Crosspoint goes beyond simply turning this into a functional device and into one that is actually fun to use. It’s got a straightforward, easy to navigate interface that makes it simple to do everything from reading to loading books (accomplished via a web-based interface). For those who like to tweak their reading setup, there are plenty of configuration...
