Xteink launched the X4 Pro e-reader at 7 AM PST on July 21, 2026, adding a touchscreen and front lighting to its compact E Ink lineup at a $99 price point through its online store (The Verge). The device carries a 4.26-inch, 800 x 480 E Ink display and sits above the $69 X4 and the $79 X3 in Xteink's current range as the premium model.

E Ink is the display technology used in most dedicated e-readers. It reflects ambient light like paper rather than emitting it, which makes it easy on the eyes and very power-efficient. Front lighting, the other new addition here, uses a thin light layer above the screen so you can read in the dark without a separate clip-on light.

The touchscreen and front lighting are the headline additions over earlier Xteink models, which lacked both. The X4 Pro is also slightly smaller and thinner than the original X4. Physical controls consist of four buttons: two for page turning, a reset, and a power/sleep toggle. A microSD card slot on the top edge handles storage expansion.

One design choice stands out for a device at this price. The X4 Pro uses a magnetic pogo-pin connector on its back rather than a built-in USB-C port. Pogo pins are small spring-loaded metal contacts that align via magnets; they carry both power and data when two devices are held together. A USB-C adapter ships in the box. Embedded magnets on the rear are designed to attach the e-reader to compatible smartphones, which is where the pogo-pin connector earns its keep: the physical and electrical pairing suggests Xteink is thinking of the X4 Pro as a phone companion screen, not just a standalone reader.

For context, Amazon's entry-level Kindle currently sits at $110, putting the X4 Pro within $11 of a device with far more brand recognition and a mature content ecosystem. What the $99 gets you instead is the phone-mounting form factor, open expandability via microSD, and the prospect of third-party firmware. The team behind CrossPoint Reader software plans to have alternative firmware ready for the X4 Pro at launch, which matters for the enthusiast audience Xteink appears to be targeting.

Xteink built anticipation with a marketing email containing a countdown timer ahead of the July 21 launch (Yahoo Tech). The company's online store also carries an accessories collection that includes a filter category for the X4 Pro, currently listing one product (Xteink).

The broader context here is the niche this device occupies. For roughly two decades, the e-reader market has been dominated by Amazon's Kindle line, with Kobo holding a meaningful secondary position. Dedicated E Ink devices outside those ecosystems have persisted at the margins, typically competing on openness, price, or form-factor novelty rather than content libraries. The X4 Pro fits that pattern: it is not trying to out-Kindle the Kindle. The phone-mounting magnet array and the pogo-pin connector point toward a use case where the e-reader functions as a secondary, low-power display attached to a phone you already carry. Whether that is a compelling enough proposition at $99 depends on how well the phone integration actually works in practice, and the verified details available so far do not cover the companion app experience or supported phone models.

The CrossPoint Reader firmware availability is a meaningful signal for the enthusiast segment. Alternative firmware on E Ink devices has historically extended functionality well beyond what manufacturers ship, and having it ready at launch rather than months later suggests coordination between Xteink and the CrossPoint team. That said, the plan is stated as an intention, and launch-day availability of third-party firmware is the kind of thing that can slip.

At $99 with a 4.26-inch screen, the X4 Pro is not competing for the reader who wants a large-format E Ink display for novels or PDFs. It is competing for the reader who wants a small, light, open secondary screen that attaches to a phone. The touchscreen and front light address the two most obvious gaps in earlier Xteink models. The pogo-pin-only charging approach is a trade-off that will frustrate some users and barely register for others. The phone-mounting magnets are the differentiator that gives the device its reason to exist beyond Xteink's own cheaper models. Whether that differentiator is enough to sustain a product at this price is a question the market will answer over the coming months.
