If you, like me, are tired of scrolling through social media to decompress and have a New Year’s resolution to read more, this new gadget might be just the thing for you. The XTEINK X4 Pro is a tiny, 4.3-inch e-reader available for $99 as a launch price (some listings note a $109 MSRP before discounts) that’s far more portable than a Kindle.
Its built-in magnetic backplate snaps to most phones that support MagSafe/Qi2‑style magnetic attachment, though actual fit and hold depend on the phone model and any case you use. So instead of getting lost in notifications, you can just flip your phone and dive into a book. No more excuses not to read more; I know your phone is already in your hand!
Why the X4 Pro beats the Kindle on pure portability
It’s a novelty, but a fun one.
A standard Amazon Kindle is great for reading in bed or sitting on the couch, but newer models are basically small tablets. You might have a dedicated bag and a protective sleeve, all of which take up space in your bag. You definitely need two hands to manage it properly during a commute.
The X4 Pro takes the exact opposite approach to mobile reading. Weighing a mere 72 grams and measuring an ultra-slim 5.95 millimetres, it’s roughly the size of a stack of credit cards and slips effortlessly into any pocket. Because it mounts directly to the back of your smartphone, your reading material travels with you wherever you go without taking up extra space.
Compared to earlier minimalist devices, this Pro version brings major quality-of-life upgrades. It has a sharp 220 PPI E-Ink touchscreen paired with a built-in front-lighting system, meaning you can read in total darkness without needing a clip-on reading lamp. Despite adding touch capabilities and lighting layers, it still keeps dedicated physical page-turn buttons on the side for easy single-handed navigation. Under the hood, you get 16GB of storage powered by a swappable microSD card that supports up to 256 gigabytes, giving you plenty of room for all your sideloaded text and EPUB files. Xteink rates the 1,100 mAh battery as lasting up to a month in light use; real‑world runtime will be shorter with the front light on, Wi‑Fi use, or heavy daily reading on a single charge under normal reading conditions, though it does drop the standard USB-C port in favor of a magnetic pogo-pin charging cable.
Since this isn’t locked to Amazon, you’ll need to load your own DRM-free books (think EPUB, MOBI, or TXT). If you’re on a computer, just plug in the X4 Pro, tap the menu on the top right, pick USB Mode, and drag your files over. Easy.
Want to go wireless? Use the app. Pair your X4 Pro by tapping the top right, showing a QR code, and scanning it with the Xteink app on your phone. Once they’re on the same Wi-Fi network, just import your book into the app and tap Cloud Sync on the reader. Done in under a minute!
Of course, you’re not just limited to using this for books. Imagine having your boarding passes, tickets, a calendar, or even important documents, right on the back of your phone. The possibilities are nearly endless! You can pick one up from the official website now.
