Design and Build Quality

Both the Bigme B7 Color ePaper Tablet and the Kobo Libra Colour showcase attractive designs, but they cater to different user preferences. The Bigme B7 features a sleek green finish, while the Kobo Libra is available in a classic white. The B7's 7-inch display emphasizes portability, making it easy to carry. In contrast, the Kobo Libra boasts an ergonomic design with page-turn buttons, enhancing user experience during long reading sessions. Additionally, the Libra's IPX8 waterproof rating ensures that it can withstand being submerged in water for 60 minutes at a depth of up to 2 meters, a feature not mentioned for the Bigme B7.

Display and Reading Experience

When it comes to display technology, both devices offer unique advantages. The Bigme B7 utilizes a color ePaper screen, allowing for vibrant visuals, while the Kobo Libra presents a full-color display that brings book covers, comics, and illustrations to life. Users can read comfortably in various lighting conditions with the glare-free screens of both devices. However, the Kobo Libra's compatibility with the Kobo Stylus 2 adds a layer of functionality, enabling users to annotate and highlight directly on the screen, enhancing the reading experience further.

Storage and Performance

In terms of performance, the Bigme B7 has a significant edge with its octa-core 2.4GHz processor, which ensures smooth multitasking and app performance. It also comes with 8GB of RAM and 128GB of internal storage, which is expandable via microSD, making it ideal for users who require ample space for documents and media. On the other hand, the Kobo Libra offers 32GB of storage, sufficient for carrying up to 24,000 eBooks, but lacks the high-performance capabilities of the B7. Overall, those seeking robust performance and storage flexibility may prefer the Bigme B7.

Connectivity and Features

Connectivity options differ significantly between the two devices. The Bigme B7 includes built-in 4G capabilities, allowing for web browsing and voice calls without relying on Wi-Fi. This feature makes it a versatile all-in-one device, merging the functionalities of a tablet and a phone. Conversely, the Kobo Libra focuses on the reading experience, providing features like customizable font sizes and page layouts, but lacks mobile connectivity. Therefore, if staying connected on the go is a priority, the Bigme B7 is the better choice.

Battery Life

Battery life is a critical consideration for e-readers, and both devices excel in this area. The Bigme B7 is equipped with a 3000 mAh battery, while specific battery life details for the Kobo Libra are not provided. However, the Kobo Libra claims to offer weeks of battery life, which is a standard expectation for e-readers. Given the B7's multifunctional nature with 4G connectivity, it's reasonable to assume that battery consumption might be higher during extensive use. Users who prioritize longevity in battery performance may lean towards the Kobo Libra.

Price Comparison

Price is an essential factor when choosing between the two devices. The Bigme B7 is priced at $289.00, while the Kobo Libra comes in slightly lower at $285.99, making it about 1% cheaper. Although the price difference is minimal, the Bigme B7 offers more features, including 4G connectivity and superior performance specifications, which could justify its higher price tag for users looking for a versatile device. Ultimately, the choice may hinge on the specific features users value most.

Bestseller Ranking

In terms of market performance, the Kobo Libra ranks slightly higher as a bestseller, holding the 51,032 position, compared to the Bigme B7's 53,605 rank. This indicates a slight preference among consumers for the Kobo Libra, likely due to its focus on reading features and user-friendly design tailored for avid readers. However, the Bigme B7's unique capabilities in multitasking and connectivity could appeal to a different segment of users who require more than just an e-reader.

Which should you buy?

Choosing between the Bigme B7 Color ePaper Tablet and the Kobo Libra Colour ultimately depends on your specific needs. If you seek a multifunctional device with robust performance, extensive storage, and connectivity features, the Bigme B7 is a compelling choice. However, if your primary focus is on a dedicated reading experience with enhanced features for annotation and a slightly lower price point, the Kobo Libra Colour is an excellent option. Consider how you plan to use your device to make the best decision for your reading and productivity needs.
