Bigme B7 Color ePaper TabletKobo Libra Colour | eReader | 7” Glare-Free Colour

Design and Display

The Bigme B7 Color features a 7-inch color ePaper display, while the Kobo Libra Colour also sports a 7-inch screen but utilizes E Ink Kaleido™ 3 technology. The Bigme B7's display offers versatility for both reading and multimedia use, while the Kobo Libra Colour focuses on providing a glare-free experience in full color, making it ideal for outdoor reading. Both devices are designed for easy portability, but the Kobo Libra’s ergonomic design includes page-turn buttons and customizable settings that enhance user comfort.

Features and Functionality

While the Bigme B7 Color integrates 4G connectivity allowing for web browsing and app usage, the Kobo Libra Colour focuses primarily on e-reading and offers features like audiobook support and compatibility with stylus annotation. The Bigme B7 also runs on Android 14, providing users with the flexibility to install various applications. On the other hand, the Kobo Libra offers seamless access to the Kobo Store and OverDrive for borrowing eBooks, positioning it as a specialized eReading device.

Storage Capacity

The Bigme B7 Color comes with 128GB of internal storage, expandable via microSD, catering to users who require extensive space for documents, apps, and media. In contrast, the Kobo Libra Colour has 32GB of storage, which can hold around 24,000 eBooks or 150 audiobooks. While the Kobo's storage is sufficient for most users, the Bigme’s significantly larger capacity is a major advantage for those who prefer to have a vast library available offline.

Battery Life

Battery life is an essential consideration for eReaders. The Bigme B7 Color is powered by a 3000 mAh battery, which supports its various functionalities including 4G calling and app usage. The Kobo Libra Colour, while having a lower power requirement due to its focused functionality, boasts weeks of battery life, an impressive feat for avid readers. The choice here depends on whether you value multifunctionality with a larger battery or a dedicated eReader experience with extended usage between charges.

Water Resistance

The Kobo Libra Colour is IPX8 rated, making it waterproof for up to 60 minutes in water depths of up to 2 meters. This feature is particularly appealing for users who enjoy reading near water or in the bath. In contrast, the Bigme B7 Color does not advertise any water resistance rating, making the Kobo Libra a more suitable option for those prioritizing durability in wet conditions.

Price Comparison

The Bigme B7 Color is priced at $289.00, while the Kobo Libra Colour is more budget-friendly at $229.99. This results in a price difference of about 17% in favor of the Kobo Libra. For users who are looking for a dedicated eReader without additional tablet features, the Kobo Libra Colour offers excellent value, while the Bigme B7 may justify its higher price through its multifunctional capabilities.

Bestsellers and Market Position

In terms of market performance, the Bigme B7 Color ranks 37,595 in sales, which indicates a niche appeal likely driven by its unique features. Conversely, the Kobo Libra Colour ranks significantly higher at 4,885, reflecting its popularity among eReaders. This suggests that many users prefer the simplicity and functionality of the Kobo, which may influence your decision if you value established market preference.

Which should you buy?

Deciding between the Bigme B7 Color and the Kobo Libra Colour ultimately depends on your specific needs. If you seek a multifunctional device that combines the features of a tablet and an eReader, the Bigme B7 Color is a solid choice, albeit at a higher price. However, if you prioritize a dedicated eReading experience with robust waterproofing and a lower price point, the Kobo Libra Colour is the better option. Each device has its strengths, making your personal reading habits and preferences the key factors in your decision.
