Dimension comparison
Display Quality
The Bigme B7 Color eReader features a superior 300PPI E-ink Kaleido 3 display, which offers clear text and vivid images. In comparison, the Kobo Clara BW has a 1300 HD E Ink Carta display that measures 6 inches. While both devices provide glare-free reading suitable for bright sunlight, the Bigme’s advanced display technology allows for a more colorful and visually rich reading experience. The difference in display quality is particularly significant for users who appreciate vibrant images and the comfort of reading in various lighting conditions.
Storage and Performance
The Bigme B7 Color eReader has a robust 128GB of storage, allowing users to accommodate approximately 70,000 books. It is powered by an Octa-Core processor with 8GB RAM, ensuring smooth performance and multitasking capabilities. In contrast, the Kobo Clara BW offers 16GB of storage, sufficient for about 12,000 eBooks. This means the Bigme provides more than five times the storage capacity, making it ideal for avid readers who require extensive libraries. The performance gap is noticeable for those who seek a device capable of handling multiple applications or heavy usage.
Connectivity Features
A notable distinction in connectivity is that the Bigme B7 supports 4G calling, allowing users to stay connected without relying solely on Wi-Fi. It features both 2.4G and 5G Wi-Fi connections, alongside Bluetooth capability. Conversely, the Kobo Clara BW does not offer cellular connectivity but does support Bluetooth for audiobooks. This makes the Bigme a more versatile option for users who want constant connectivity, especially in areas without Wi-Fi.
Usability and Ergonomics
The Bigme B7 Color eReader is equipped with customizable keys, enhancing user efficiency significantly. It also includes a stylus for note-taking and document annotation, making it a practical choice for students and professionals. The Kobo Clara BW, while simpler, prioritizes ease of use with built-in ComfortLight PRO for adjustable brightness and color temperature. However, it lacks the advanced usability features present in the Bigme, which may appeal more to users looking for a multifunctional device.
Battery Life
The Bigme B7 touts long battery life that can last for weeks, which is crucial for readers who want to avoid frequent recharging. The Kobo Clara BW also offers weeks of battery life, but the exact duration is not specified. While both devices excel in this area, the Bigme's advanced features suggest that it maintains its battery life even with more demanding tasks, such as using apps and making calls, which is an important consideration for heavy users.
Water Resistance
For users concerned about durability, the Kobo Clara BW is rated IPX8 waterproof, making it suitable for reading by the pool or at the beach. It can withstand immersion in water for up to 60 minutes in depths of up to 2 meters. The Bigme B7 does not mention any water resistance features, which could be a downside for those who enjoy reading in wet or humid environments. If you frequently read in such conditions, the Kobo may provide added peace of mind.
Price Comparison
The Bigme B7 Color eReader is priced at $319.97, while the Kobo Clara BW is significantly cheaper at $168.99, making it about 47% less expensive. This substantial price difference may make the Kobo more appealing to budget-conscious readers or those new to eBooks. However, the Bigme’s higher price reflects its advanced features, such as a larger storage capacity and enhanced functionality, potentially justifying the investment for serious readers.
Which should you buy?
Choosing between the Bigme B7 Color eReader and the Kobo Clara BW ultimately depends on your specific reading needs and preferences. If you prioritize advanced features such as a superior display, extensive storage, and multifunctionality, the Bigme B7 is worth the higher price. However, if you are looking for a reliable, budget-friendly eReader with great waterproof capabilities and simplicity, the Kobo Clara BW may be the better choice. Each device has its strengths, catering to different types of users in the ever-growing eReader market.
