Xteink's Tiny E-Readers Drop 20% in Price for Amazon Prime Day 2025
If you've ever wished your e-reader could slip into a shirt pocket or stick to the back of your phone like a second skin, Amazon Prime Day 2025 has brought you an offer worth taking seriously. The Xteink X4 and Xteink X3 — two of the most compact e-readers on the market today — are both discounted by 20 percent for a limited time as part of Amazon's Prime Day promotions. Whether you're a dedicated bookworm looking to downsize your carry or a casual reader curious about alternatives to Kindle and Kobo, these tiny devices deserve a close look.
Prime Day Pricing: What You'll Pay
For Prime Day, Amazon has knocked a meaningful chunk off the regular retail price of both Xteink models. The Xteink X4 is available for $55.20, down from its standard price of $69 — a savings of nearly $14. The Xteink X3 comes in at $63.20, reduced from the regular $79 price tag. Both deals are live through Amazon's Prime Day event window, so if you've been on the fence about picking one up, now is the most affordable time to make the jump.
It's worth noting that you can also purchase both models directly from Xteink's own website, though at the time of writing those prices remain at the standard $69 and $79 respectively. Amazon is clearly the place to shop during this promotional period.
Why Xteink E-Readers Are Different From Kindle and Kobo
The Xteink X4 and X3 occupy a genuinely unusual niche in the e-reader market. While Amazon's Kindle lineup and Kobo's various models are excellent devices, they all share one common trait: they're relatively large slabs of glass and plastic that require a bag or a large pocket to carry comfortably. Xteink has taken a completely different approach, engineering e-readers that are significantly smaller and more pocketable than anything currently offered by either of those brands.
Perhaps the most eye-catching feature of both Xteink models is their built-in magnetic mount. Both the X4 and X3 are designed to attach directly to the back of a MagSafe-compatible smartphone, essentially turning your phone into a host device for your e-reader. This is a genuinely clever solution for readers who want their book within arm's reach at all times without carrying a separate bag or dedicated case.
A Closer Look at the Xteink X4
The X4 is Xteink's slightly larger offering, and in hands-on testing it has shown a number of strengths that make it appealing to serious readers. The device features dedicated physical buttons for turning pages — a feature that many longtime e-reader fans strongly prefer over touchscreen-only navigation. The buttons provide satisfying tactile feedback and allow for one-handed reading without needing to adjust your grip or tap the screen.
Battery life is another standout quality of the X4. Like most e-ink displays, it stretches impressively long between charges, making it well-suited for travel, commuting, or situations where access to a power source is limited. Loading content onto the device is also flexible, with several supported methods for sideloading books and documents — a welcome feature for readers who manage their own digital libraries.
The main area where the X4 falls short is its bundled software. Navigation can be cumbersome, particularly because the interface was not originally designed with button-only control in mind. However, this is a problem with a readily available solution. Both the X4 and X3 can be upgraded to the free CrossPoint Reader firmware, which delivers a significantly more polished and user-friendly experience. The upgrade is straightforward and transforms the day-to-day usability of the device considerably.
One important trade-off to keep in mind: unlike Kindle or Kobo devices, the Xteink X4 does not give you access to a dedicated online bookstore. You won't be browsing and purchasing titles directly from the device. If your reading library lives in the Kindle or Kobo ecosystems, that's something to consider before buying.
A Closer Look at the Xteink X3
The X3 shares the same core functionality as the X4 but comes packaged in an even smaller form factor. It features an improved button layout compared to the X4, making physical navigation a bit more intuitive right out of the box. Its smaller size also means it's compatible with a broader range of smartphones when used in magnetic mount mode — particularly useful for owners of more compact handsets.
If ultra-portability is your top priority, the X3 wins out. It can slip into the smallest of pockets and barely registers as extra weight in a jacket or bag. For readers who are always on the move and want the absolute minimum footprint, it's a compelling pick at the Prime Day price of $63.20.
The one genuine drawback specific to the X3 is its reliance on a proprietary magnetic USB charging cable. In an era when USB-C has become the universal standard, being locked into a bespoke charging solution is a real inconvenience. Lose the cable while traveling and you won't be able to charge the device until a replacement arrives. For readers prone to misplacing cables, this is a factor worth weighing carefully.
Should You Buy an Xteink E-Reader on Prime Day?
If you're looking for a conventional Kindle replacement with a full-featured bookstore and a polished out-of-the-box experience, the Xteink devices are probably not the right fit. But if you want something genuinely pocket-sized, MagSafe-compatible, and adaptable through third-party firmware, both the X4 and X3 offer a compelling and distinctive experience at a price that's hard to argue with during Prime Day.
At 20 percent off, the X4 at $55.20 is the easier recommendation for most readers thanks to its slightly larger display and more flexible charging. The X3 at $63.20 makes sense for those who prioritize the smallest possible form factor and are comfortable managing a proprietary cable. Either way, the CrossPoint Reader firmware upgrade goes a long way toward making whichever model you choose feel like a complete, polished product.
Prime Day deals move fast, so if either of these compact e-readers sounds like the right tool for your reading life, it's worth acting sooner rather than later.
