Dimension comparison
Design and Display Quality
The Bigme B7 Color eReader features a 7-inch E-ink Kaleido 3 display, while the PocketBook Era also boasts a 7-inch screen with E-ink technology. The Bigme's display offers a resolution of 300PPI, ensuring vivid images and clear text, which is particularly beneficial for long reading sessions. In contrast, the PocketBook Era employs the E Ink Carta 1200 screen, which provides a 15% increase in image contrast and a 20% boost in touch response time. Both devices are designed to be glare-free, allowing users to read comfortably in various lighting conditions, although the PocketBook's screen is specifically noted for its performance in bright sunlight.
User Interface and Navigation
The Bigme B7 Color eReader runs on Android 14, enabling the installation of third-party apps and providing a more versatile user experience. It also supports both 2.4G and 5G WiFi connections and includes Bluetooth capabilities. On the other hand, the PocketBook Era is more focused on simplicity, allowing users to read any file without conversion and supports 23 popular formats, including 17 book formats. The added side control buttons and G-sensor make it user-friendly for both right and left-handed readers, enhancing the overall navigation experience.
Storage and Performance
In terms of storage, the Bigme B7 Color eReader comes with a substantial 128GB of internal storage, allowing for approximately 70,000 books. It is powered by an advanced Octa-Core processor, ensuring smooth performance. Conversely, the PocketBook Era provides 16GB of storage, which is sufficient for many users but may require more frequent management of content for avid readers. While the Bigme offers expandable storage options up to 1TB via microSD, the PocketBook's storage is not expandable, making it less versatile in this regard.
Connectivity Features
The Bigme B7 Color eReader stands out with its 4G calling support, which allows users to stay connected even when away from WiFi. This feature is complemented by a stylus that supports note-taking and document annotation, enhancing its functionality beyond standard reading. The PocketBook Era, while lacking 4G support, includes Bluetooth for audio connectivity, enabling users to listen to audiobooks through headphones or the built-in speaker. It also features Text-to-Speech capabilities, allowing the device to read aloud any text file in 26 languages, which can be particularly appealing for users who enjoy auditory learning.
Battery Life and Usage
Both devices are designed for long-lasting use, but they approach battery life differently. The Bigme B7 Color eReader's battery life is designed to last for weeks, depending on usage, thanks to its efficient power management. The PocketBook Era also boasts a long battery life, with claims that it only requires charging once a month under typical usage conditions. This makes both devices suitable for users who prefer not to charge their e-readers frequently, especially during travel or commuting.
Price and Value
The Bigme B7 Color eReader is priced at $319.97, making it about 28% more expensive than the PocketBook Era, which retails for $249.00. While the Bigme offers advanced features such as 4G connectivity and larger storage, the PocketBook provides a solid reading experience with its waterproof design and enhanced screen technology at a more budget-friendly price. Considering the bestseller rankings, the PocketBook Era holds a better position at 30,379, compared to the Bigme's rank of 66,991, suggesting a stronger market appeal.
Which should you buy?
Choosing between the Bigme B7 Color eReader and the PocketBook Era ultimately depends on individual preferences and reading habits. If you value a larger storage capacity, advanced features like 4G calling, and a more versatile Android interface, the Bigme B7 is an excellent choice despite its higher price point. However, if you prefer a budget-friendly option with great display quality, waterproof capabilities, and user-friendly features, the PocketBook Era is a compelling alternative. Both devices offer unique advantages that cater to different types of readers.
