Introduction

The e-reader landscape is often dominated by larger devices, but Xteink is challenging that norm with a pocket-sized alternative that proves great reading doesn't require a bulky screen. The Xteink X4 Pro combines a credit-card form factor with features usually found on larger models, offering a truly portable way to enjoy books anywhere.

What Happened

Right now, the Xteink X4 Pro is available at a 15% discount ahead of October Prime Day 2026. The device normally retails for $99 but drops to $85 during the early sale event. This latest version upgrades the original X4 by adding a temperature-adjustable front light, a responsive touchscreen, a faster processor, and extra memory—all while keeping the same ultra-compact size.

Why This Matters

For readers who prefer e-ink over smartphone screens, the X4 Pro offers a truly portable way to enjoy books anywhere. Its pocketable design means you can slip it into any bag or jacket pocket and never be without a book. The front light enables comfortable reading in low light, and the touchscreen adds a level of convenience that earlier button-only models lacked. However, the device isn't for everyone: it doesn't support DRM-protected Kindle libraries, and the small screen takes some getting used to.

Key Takeaways

  • Credit-card-sized e-reader with front light and touchscreen
  • 15% off during early October Prime Day, bringing price to $85
  • Upgrades over the original X4 include adjustable lighting and touch input
  • Ideal for readers who value portability and distraction-free focus
  • Cannot access DRM-protected Kindle or Amazon libraries

Conclusion

If you've been curious about tiny e-readers but hesitated at the lack of features, the Xteink X4 Pro delivers a compelling balance of size, functionality, and price. The front light and touchscreen upgrade make it worth considering over the original model, especially at a discounted rate. Just be sure your e-book collection is DRM-free, and you'll have a uniquely convenient reading companion that goes wherever you do.
