Display Quality and Reading Experience

The Kobo Libra Colour offers a significantly larger 7-inch glare-free color E Ink Kaleido 3 display, delivering vivid visuals for books with illustrations, comics, and graphic novels. This full-color screen brings book covers and annotations to life in ways a monochrome display cannot match. In contrast, the XTEINK X4 features a compact 4.3-inch E-Ink screen that provides a natural paper-like reading experience but only in black and white. While both screens are designed to reduce eye strain, the Libra Colour’s color capability is a major advantage for visual content. The Libra also supports landscape mode and customizable font sizes and margins, enhancing comfort during extended reading sessions. The XTEINK X4, while optimized for distraction-free reading, lacks these advanced formatting options. For readers who value visual richness and flexibility in layout, the Libra Colour clearly outperforms the XTEINK X4.

Portability and Physical Design

The XTEINK X4 wins decisively on portability, weighing just 2.72 oz and measuring 0.23 inch thick—making it truly pocket-sized. Its ultra-thin profile allows it to slip easily into small bags or even a coat pocket, ideal for quick reading breaks or travel. The Kobo Libra Colour, while ergonomically designed, is substantially heavier and bulkier due to its larger screen and waterproof casing. It’s not intended for constant pocket carry. However, the Libra’s design includes physical page-turn buttons and left/right screen rotation, which enhance usability during long reading sessions. The XTEINK X4 also features magnetic-ready design via an included ring, enabling secure attachment to phones or other magnetic surfaces—though this requires external accessories. For users prioritizing minimal weight and size, the XTEINK X4 is unmatched.

Storage Capacity and Media Options

The Kobo Libra Colour comes with 32GB of storage, capable of holding up to 24,000 eBooks or 150 Kobo Audiobooks, offering ample space for extensive digital libraries. It also integrates seamlessly with Kobo Plus (which includes a 30-day trial), OverDrive for library borrowing, and Pocket for saved articles. These features expand access beyond purchased books. The XTEINK X4, by comparison, has only 16GB of storage—half as much—as its primary competitor. While still sufficient for thousands of books, it lacks integration with audiobook services, library apps, or subscription platforms. It operates as a standalone device with no built-in media ecosystem. For users seeking a broad range of content sources and audio support, the Libra Colour’s storage and connectivity advantages are substantial.

Battery Life and Charging

Both devices offer impressive battery longevity, but their usage profiles differ. The XTEINK X4 boasts a claimed 14-day battery life based on typical use of 1–3 hours per day, powered by a 650 mAh battery. This makes it ideal for travelers or those who prefer infrequent charging. The Kobo Libra Colour promises weeks of battery life, though the exact duration isn’t specified. Given its larger screen and additional features like color display and waterproofing, its power consumption is likely higher than the XTEINK X4’s. However, the Libra’s longer battery life suggests efficient power management despite added functionality. For users who prioritize low maintenance and extended use between charges, the XTEINK X4’s 14-day claim gives it a measurable edge in practical terms.

Waterproofing and Durability

The Kobo Libra Colour stands out with IPX8 waterproof certification, meaning it can withstand immersion in up to 2 meters of water for 60 minutes—ideal for beach trips, poolside reading, or accidental spills. This level of protection is rare among e-readers and adds significant peace of mind. The XTEINK X4 does not mention any waterproof rating, relying instead on high-aluminosilicate glass for enhanced durability and clarity. While this improves scratch resistance, it doesn’t protect against liquid exposure. Users must handle the XTEINK X4 with greater care. For anyone who reads near water or in unpredictable environments, the Libra Colour’s IPX8 rating is a critical differentiator.

Price and Value Proposition

The XTEINK X4 is priced at $69.00, making it about 70% cheaper than the Kobo Libra Colour, which costs $229.99. This represents a price difference of $160.99—a significant saving for budget-conscious buyers. At under $70, the XTEINK X4 offers a no-frills, dedicated reading experience with strong portability and decent battery life. The Libra Colour, while more expensive, delivers far more features: color display, audiobook support, waterproofing, and ecosystem integration. For users willing to invest in a premium, multifunctional device, the Libra Colour justifies its higher cost through expanded utility. However, for those seeking a simple, lightweight reader without extras, the XTEINK X4 provides exceptional value at nearly one-third the price.

Which should you buy?

Choose the Kobo Libra Colour if you want a feature-rich, full-color e-reader with waterproofing, audiobook support, and integration with libraries and subscriptions—ideal for readers who value versatility, visual content, and long-term durability. It’s especially suited for graphic novel fans, students, and frequent travelers. Opt for the XTEINK X4 if your priority is extreme portability, minimal weight, and a distraction-free reading experience at a fraction of the cost—perfect for commuters, casual readers, or those who want a backup device that fits in a pocket. With a bestseller rank of 887 compared to the Libra’s 2,628, the XTEINK X4 enjoys stronger current demand, reflecting its appeal as a budget-friendly, niche product. Ultimately, the choice hinges on whether you need advanced features or maximum simplicity.
