Xteink's Tiny E-Readers Are 20% Off for Prime Day — Are They Worth It?
If you've been on the hunt for a compact, pocketable e-reader that goes beyond what Kindle and Kobo can offer in terms of portability, Amazon's Prime Day 2025 may have just delivered exactly what you didn't know you needed. Xteink, a lesser-known but increasingly popular name in the e-reader space, has slashed prices on two of its most exciting devices: the Xteink X4 and the even smaller Xteink X3. Both are now 20 percent off for a limited time, making this one of the most intriguing e-reader deals of the Prime Day season.
Whether you're a commuter who devours novels on a packed subway, a student looking for a distraction-free reading tool that fits in your shirt pocket, or a book lover curious about alternatives to mainstream devices, this deal deserves a closer look. Let's break down what each model offers, what the trade-offs are, and whether now is the right time to buy.
Prime Day Pricing: How Much Can You Save?
During Amazon's Prime Day promotions, both Xteink e-readers are available at a meaningful discount. The Xteink X4, normally priced at $69, is currently on sale for $55.20. The Xteink X3, which typically retails for $79, is discounted to $63.20. That's a flat 20 percent off both devices — a solid saving given how niche and specialized these products are. You can purchase either directly through Amazon's Prime Day listings or through Xteink's own website, though the Prime Day pricing is exclusive to Amazon.
For context, entry-level Kindle models often start around $100 or more for the basic version with ads, and Kobo devices can run even higher. At these Prime Day prices, the Xteink X4 and X3 represent genuinely competitive value — especially given their unique form factor.
What Makes Xteink E-Readers Different?
The most immediately obvious distinction between Xteink's offerings and the dominant players in the market is size. Both the X4 and the X3 are significantly smaller and more pocketable than any Kindle or Kobo currently available. We're talking about devices that can genuinely slip into the front pocket of a pair of jeans, a jacket breast pocket, or a small purse compartment without any awkward bulk.
But perhaps the most eye-catching feature — literally — is the magnetic mounting system. Both devices are equipped with magnetic mounts that allow them to attach directly to the back of MagSafe-compatible smartphones. This design choice opens up some genuinely novel use cases: imagine having your e-reader snapped to the back of your iPhone while you're on the go, ready to detach and read in seconds. It's a clever, modern approach to portability that no mainstream e-reader manufacturer has yet embraced.
Xteink X4: A Closer Look
The Xteink X4 is the larger of the two models and tends to suit readers who want a balance between compactness and a slightly more traditional reading experience. One of its standout qualities is its physical button layout, which allows users to turn pages without needing to tap a touchscreen. For readers who prefer tactile feedback — or who simply don't want fingerprints smudging an E Ink display — this is a genuine quality-of-life improvement.
Battery life on the X4 is excellent, living up to the reputation E Ink displays have earned for low power consumption. You can expect to go days or even weeks between charges depending on your reading habits. The device also supports several methods for loading books and documents, offering more flexibility than you might expect at this price point.
However, there are genuine caveats to consider. The bundled software that ships with Amazon's version of the X4 has been described as rough around the edges, and navigating it using physical buttons rather than a touchscreen can be frustrating at times. There is also no access to a dedicated online bookstore. Unlike a Kindle, which connects seamlessly to Amazon's vast library, or a Kobo, which ties into its own store, the X4 requires you to source and sideload your own content. For some readers, this is liberating; for others, it may be a dealbreaker.
The good news is that the Amazon version of the X4 is compatible with CrossPoint Reader, a free alternative firmware that provides a significantly more polished user interface. Upgrading to CrossPoint is straightforward and goes a long way toward smoothing out the software experience.
Xteink X3: The Ultraportable Option
The X3 shares much of the same core functionality as the X4 but leans even harder into the ultraportable philosophy. It is smaller than the X4, features a refined button layout that many users will find more intuitive, and is particularly well-suited for pairing with smaller smartphones thanks to its improved magnetic mount compatibility.
If your priority is having the most pocketable e-reader imaginable — something that genuinely disappears into your daily carry — the X3 is the stronger choice. It is even easier to tuck into a small pocket or clip onto a bag without adding noticeable weight or bulk.
That said, the X3 does come with one notable potential frustration: it relies on a proprietary magnetic USB charging cable. Anyone who has lived through the era of proprietary charging systems knows the pain of losing a unique cable and being unable to charge a device until a replacement arrives. If you're prone to misplacing cables or frequently travel without your full kit, this is worth factoring into your decision.
CrossPoint Reader: The Software Fix You'll Want
Both the X4 and the X3 can be upgraded to CrossPoint Reader firmware, and if you buy either device, doing so is strongly recommended. CrossPoint Reader transforms the user interface into something far more polished and intuitive, addressing the most common complaints about the bundled software. The upgrade is free, relatively simple to perform, and makes a meaningful difference in day-to-day usability. Think of it as an essential first step after unboxing rather than an optional modification.
Who Should Buy an Xteink E-Reader?
The Xteink X4 and X3 are not for everyone, and it's important to be clear-eyed about that. If you rely on a robust digital bookstore, seamless cloud syncing, or a polished out-of-the-box software experience, a Kindle or Kobo will likely serve you better. Both of those ecosystems are more mature, more integrated, and more beginner-friendly.
But if you value extreme portability above all else, are comfortable sideloading your own ebooks and documents, and find the MagSafe magnetic mount concept genuinely appealing, Xteink's devices fill a niche that no one else currently occupies. At Prime Day pricing, the barrier to entry is low enough that curious readers can take the plunge without a significant financial risk.
Final Verdict: Should You Buy During Prime Day?
The 20 percent Prime Day discount on the Xteink X4 and X3 makes this a compelling moment to try something genuinely different in the e-reader space. At $55.20 for the X4 and $63.20 for the X3, you're paying below the cost of an entry-level Kindle for devices that offer a truly unique size and form factor. The software limitations are real but addressable with the free CrossPoint Reader upgrade, and the hardware quality — particularly the battery life and physical button controls — is impressive for the price.
If you've ever wished your e-reader could fit in your pocket the way your phone does, or if the idea of snapping a reading device to the back of your iPhone sounds like it was designed specifically for your lifestyle, this Prime Day deal is worth acting on. The window for Prime Day pricing is limited, so if either device sounds like it fits your reading life, now is the time to make the move.
