Introduction
Compact e-readers are becoming increasingly popular, especially for users who want a lightweight device they can carry anywhere. The Xteink X3 takes portability to the next level with its ultra-small, credit card-like design.
While it brings several improvements over its predecessor, one critical flaw holds it back from being the perfect pocket-sized reading companion. Let’s take a closer look at what this device does well—and where it falls short.
A Smaller and More Portable Design
The Xteink X3 is even slimmer and more compact than the earlier Xteink X4. It’s thinner, narrower, and shorter, making it one of the smallest e-readers currently available.
Key Design Highlights
Nearly the size of a credit card
Extremely lightweight and easy to carry
Fits comfortably in your pocket without adding bulk
Although it doesn’t quite fit inside a wallet slot, its compact form makes it highly convenient for reading on the go.
Improved Magnetic Mount (But Still Imperfect)
One of the standout features is its magnetic backing, designed to attach the e-reader to the back of a smartphone like the iPhone 16 Pro.
What’s Better
Improved magnet positioning for better alignment
More practical attachment compared to the previous model
What’s Still Lacking
Weak magnetic strength
Device can easily slip or fall off during movement
While the idea is great, the execution still needs refinement to make it truly reliable.
Display Quality and Reading Experience
The X3 features a 3.7-inch E Ink display, slightly smaller than its predecessor but with a sharper resolution.
Display Features
Crisp text with around 250ppi
Comfortable for reading small fonts
Ideal for quick reading sessions
However, the small screen size may not suit everyone. Users who prefer larger text will need to turn pages more frequently, which can disrupt the reading flow.
Simplified Controls for Better Usability
The X3 introduces a cleaner button layout, making navigation easier than before.
Improvements Include
Single buttons on each side for page turning
Dual-function buttons below the screen for menu navigation
Reduced complexity compared to earlier versions
Despite these changes, the interface still requires some time to get used to.
Software Experience Better, But Not Perfect
The software on the X3 has seen some upgrades, but it still feels unpolished compared to mainstream e-readers.
What’s Improved
On-screen labels for buttons (on the home screen)
Additional text spacing options
Wireless file transfer support
Ongoing Issues
Labels disappear outside the home screen
Overall interface feels clunky
For users accustomed to smoother systems like Amazon Kindle, the X3 may feel less intuitive.
Unique Features Worth Mentioning
The X3 includes a few interesting additions that enhance its functionality:
Shake-to-turn pages: A fun but slightly unnecessary feature
microSD card support: Makes file transfer easier and more flexible
Wireless syncing: Works, but can feel complicated
In most cases, directly transferring files via microSD remains the simplest method.
Battery Life and Charging
The device offers a respectable battery life of up to two weeks, which is impressive for its size.
However, this is where the biggest issue appears.
The Biggest Flaw No USB-C Port
Instead of using a standard USB-C connection, the X3 relies on a magnetic pogo-pin charging cable.
Why This Is a Problem:
Proprietary cable is easy to lose
No widely available replacements (yet)
Inconvenient compared to universal USB-C
In today’s world, where USB-C has become the standard across devices, this decision feels outdated and frustrating. Even a slightly thicker design with USB-C support would have been a better trade-off.
Who Should Consider the Xteink X3?
This device is best suited for:
Readers who prioritize extreme portability
Users who want a distraction-free reading experience
People who prefer a dedicated e-reader over smartphones
However, it may not be ideal for:
Users who want a polished software experience
Readers who prefer larger screens
Anyone who dislikes proprietary charging solutions
Final Verdict
The Xteink X3 is a fascinating device that pushes the limits of portability in the e-reader market. Its compact design, improved controls, and decent display make it a strong option for casual reading on the go.
However, the lack of a USB-C port is a significant drawback that can’t be ignored. In a time when convenience and standardization matter more than ever, relying on a proprietary charging cable feels like a step backward.
Bottom Line
If portability is your top priority, the X3 is worth considering. But if you value convenience and ease of use, you may want to explore other options.
