Introduction

E-reader enthusiasts tracking Amazon's October 2026 Prime Day won't want to miss this standout offer. The Xteink X4 Classic, a credit card-sized device built for readers who value portability and crisp text, is available at its lowest price yet.

What Happened

Xteink, a Chinese startup that disrupted the e-reading market with the original X4, has dedicated the last year to refining its lineup. The X4 Classic, launched earlier this month, builds on that foundation with a larger battery, relocated page-turn buttons, a real-time clock, USB drive support, and a tilt-to-turn-page feature. It's also 6 grams lighter and 1 millimeter thinner than its predecessor, though the shift from USB-C to magnetic pogo pins means users need a separate cable or adapter.

  • Larger battery for extended reading sessions
  • Relocated page-turn buttons for easier access
  • Real-time clock and USB drive support
  • Tilt-to-turn-page functionality
  • 6g lighter and 1mm thinner than the X4

Why This Matters

At $75.99, the X4 Classic hits a sweet spot for readers who prioritize text clarity over built-in lights or touchscreens. Unlike Kindle devices, this e-reader supports only DRM-free e-books, so it won't integrate with existing Amazon libraries. The 15% discount makes it one of the most affordable entry points into dedicated, pocket-sized e-ink reading.

Key Takeaways

  • The Xteink X4 Classic is 15% off, dropping to $75.99—its all-time low price
  • It trades built-in lighting and touch input for a thinner, lighter design and cleaner text display
  • Best suited for readers with DRM-free e-book collections who want maximum portability
  • Early Prime Day deal makes it an ideal time to purchase before the October 6-7 sale event

Conclusion

If you've been curious about stepping into the world of ultra-compact e-readers, this is the moment. The Xteink X4 Classic combines a sub-$80 price point with genuine portability, making it a compelling choice for casual and avid readers alike—provided your e-book library is DRM-free. With the Prime Big Deal Days just days away, grabbing it at this price could mean securing a unique reading tool at its cheapest point of the year.
