Dimension comparison
Design and Display
The Bigme B7 Pro Color e-Reader features a 7-inch E-Ink Kaleido 3 display with a resolution of 300PPI, ensuring a vivid reading experience. In comparison, the Kobo Libra Colour also boasts a 7-inch E Ink Kaleido 3 display, offering a glare-free reading environment. While both devices are designed for comfortable reading, the Bigme's advanced display technology allows for a true paper-like experience, making it ideal for long reading sessions. Additionally, the Bigme's display supports smoother video and animation playback, enhancing its versatility beyond traditional reading.
Performance and Storage
When it comes to performance, the Bigme B7 Pro Color is equipped with an upgraded MediaTek Dimensity 1080 Octa-core processor and has a substantial 8GB of RAM, paired with 256GB of internal storage. This allows it to accommodate approximately 160,000 books and supports microSD expansion up to 2TB. On the other hand, the Kobo Libra Colour offers 32GB of storage, sufficient for about 24,000 eBooks or 150 audiobooks. The Bigme's superior processing power and storage capacity provide a significant advantage for users who require multitasking and extensive media storage, highlighting its versatility as an e-reader.
Connectivity
The Bigme B7 Pro Color offers 4G global connectivity, allowing users to stay connected anywhere with a compatible Nano SIM. This feature is particularly useful for those who enjoy downloading books or accessing online content on-the-go. In contrast, the Kobo Libra Colour primarily relies on Wi-Fi connectivity for internet access, which may limit its functionality for users who frequently travel or are in areas with poor Wi-Fi signal. The inclusion of 4G in the Bigme makes it a more flexible option for those who prioritize constant connectivity.
Note-Taking and Annotation Features
The Bigme B7 Pro Color includes a wireless charging stylus, enabling users to take notes, annotate documents, and perform creative tasks directly on the screen. This capability is enhanced by its borderless handwriting feature, allowing for a fluid writing experience without being restricted by screen boundaries. While the Kobo Libra Colour supports stylus compatibility for annotations and highlights, the stylus is sold separately and lacks the same level of integration as found in the Bigme. Consequently, the Bigme is better suited for users who prioritize note-taking and annotation capabilities.
Battery Life
Both devices are designed to provide long battery life, but the exact durations are not specified in the available data. However, the Bigme B7 Pro Color’s capabilities, including its large storage and advanced processing power, suggest that it is built for extended use, potentially lasting weeks between charges. The Kobo Libra Colour also emphasizes weeks of battery life, making it a reliable choice for avid readers. Users looking for an e-reader that can last through long trips without frequent charging may find both options appealing, but the Bigme's advanced features imply it may require more frequent charging under heavy use.
Waterproofing
The Kobo Libra Colour stands out with its IPX8 waterproof rating, which means it can withstand immersion in water for up to 60 minutes at a depth of 2 meters. This feature is particularly advantageous for readers who enjoy relaxing by the pool or at the beach. In contrast, the Bigme B7 Pro Color does not mention any waterproofing features, which could be a drawback for users who want to read in more adventurous or humid environments. Therefore, if waterproofing is a priority, the Kobo Libra Colour is the superior choice.
Price Comparison
The Bigme B7 Pro Color is priced at $427.49, while the Kobo Libra Colour is significantly more affordable at $229.99, making it about 46% cheaper. This price difference reflects the additional features and capabilities of the Bigme, such as its advanced processing power and storage options. However, for users primarily interested in a straightforward e-reading experience without the extra features, the Kobo Libra Colour provides excellent value for money. The choice ultimately depends on the user’s budget and feature requirements.
Which should you buy?
Choosing between the Bigme B7 Pro Color and the Kobo Libra Colour largely depends on your specific needs as a reader. If you seek a versatile device with extensive storage, note-taking capabilities, and 4G connectivity, the Bigme B7 Pro Color is worth the investment. However, if you prefer a more straightforward, cost-effective option with waterproofing and sufficient storage for casual reading, the Kobo Libra Colour is a strong contender. Ultimately, consider your reading habits and preferences to make the best choice for your e-reading experience.
