Display Quality and Reading Experience

The Kobo Libra Colour offers a significantly larger 7-inch glare-free color E Ink Kaleido™ 3 display, while the XTEINK X4 features a compact 4.3-inch monochrome E-Ink screen. The Libra Colour’s full-color capability brings book covers, comics, and illustrations to life with vibrant detail—ideal for visual content—whereas the X4 delivers a traditional paper-like reading experience focused on text clarity. The Libra Colour’s anti-glare surface ensures visibility in sunlight, but it lacks mention of refresh rate or color accuracy specs. In contrast, the X4’s smaller size enhances portability but limits immersion for longer texts. For readers prioritizing visual richness and screen real estate, the Libra Colour is unmatched; however, those seeking distraction-free simplicity may prefer the X4’s minimalist design.

Portability and Design

The XTEINK X4 wins decisively in portability: at just 2.72 oz and 0.23 inch thick, it fits easily into pockets or small bags. The Kobo Libra Colour, though ergonomically designed, is not described with exact dimensions or weight, but its larger 7-inch screen suggests a bulkier profile. The X4’s magnetic-ready design allows attachment to phones or surfaces via an included ring, enabling quick access during commutes or travel. The Libra Colour includes physical page-turn buttons and supports left/right screen rotation, enhancing usability during extended reading sessions. While both devices prioritize user comfort, the X4’s ultra-thin build makes it ideal for on-the-go use, whereas the Libra Colour suits home or desk-based reading.

Storage and Media Capacity

The Kobo Libra Colour offers 32GB of storage, capable of holding up to 24,000 eBooks or 150 Kobo audiobooks. This substantial capacity supports extensive digital libraries and multimedia integration. The XTEINK X4 provides only 16GB of storage, sufficient for thousands of books but less than half the Libra Colour’s capacity. Neither device mentions cloud sync or expandable memory, so users must rely solely on internal storage. For avid readers with large collections or those who frequently listen to audiobooks, the Libra Colour’s 32GB is a clear advantage. The X4 remains adequate for casual readers with modest library sizes.

Battery Life and Charging

The XTEINK X4 boasts a 14-day battery life based on typical usage (1–3 hours per day), powered by a 650 mAh battery. This long endurance means fewer charging interruptions, ideal for travelers or users who read infrequently. The Kobo Libra Colour promises “weeks of battery life,” though no specific duration is provided. Given its larger screen and advanced features like color display and waterproofing, its battery performance is likely robust but unspecified. The X4’s defined 14-day estimate offers more predictable planning, while the Libra Colour’s vague claim leaves users uncertain about actual longevity under heavy use.

Price and Value for Money

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 savings of $160.99—nearly 70% off the Libra Colour’s price. With a bestseller rank of 887 compared to the Libra Colour’s 4,885, the X4 enjoys stronger market traction despite its lower price point. The Libra Colour’s premium cost reflects its advanced features: full-color display, waterproof IPX8 rating, and 32GB storage. However, for budget-conscious buyers or those seeking a simple reading device, the X4 delivers exceptional value at nearly one-third the price.

Special Features and Functionality

The Kobo Libra Colour stands out with IPX8 waterproofing, allowing submersion up to 2 meters for 60 minutes—ideal for beach reading or accidental spills. It also supports Kobo Stylus 2 compatibility for colored annotations and note-taking, a unique feature absent in the XTEINK X4. Additionally, it integrates with Kobo Plus (30-day trial), OverDrive for library borrowing, and Pocket for saved articles. The XTEINK X4 focuses purely on reading: no subscriptions, no notifications, and no external integrations. Its magnetic ring enables quick access, but it lacks any support for styluses or multimedia playback. The Libra Colour excels in ecosystem depth and durability; the X4 shines in minimalism and distraction-free focus.

Which should you buy?

Choose the Kobo Libra Colour if you want a full-color e-reader with waterproof protection, 32GB storage, and advanced features like stylus-compatible note-taking, audiobook support, and seamless integration with Kobo Plus and OverDrive. Despite costing $229.99—over three times the price of the XTEINK X4—it offers a richer, more versatile reading experience tailored for visual content and long-term use. Opt for the XTEINK X4 if portability, affordability, and distraction-free reading are your top priorities. At $69.00, it’s about 70% cheaper and designed for pocket-sized convenience with a 14-day battery life and magnetic attachment. For most readers, the X4 delivers excellent value; but for those who demand color, durability, and ecosystem depth, the Libra Colour is worth the investment.
