Dimension comparison
Display Quality
When it comes to display quality, the PocketBook Era Color Ereader features a 7-inch Kaleido 3 screen that delivers sharp black-and-white text alongside vivid colors. This makes it ideal for reading ebooks, comics, and magazines, providing a paper-like experience. In contrast, the Bigme B7 Color ePaper Tablet also sports a 7-inch display, but its focus is more on functionality with its tablet capabilities, including 4G calling and app usage. The Kaleido 3 technology in the PocketBook is specifically designed to enhance color visibility and text clarity, making it a more specialized choice for readers who prioritize visual quality.
Functionality and Versatility
The Bigme B7 Color ePaper Tablet excels in versatility, functioning not just as an e-reader but also as a tablet with 4G calling capabilities. This allows users to browse the web, install apps, and make voice calls without relying on Wi-Fi. On the other hand, the PocketBook Era is primarily an e-reader with a focus on providing a seamless reading experience, including features like text-to-speech and audiobooks. While the Bigme offers a broader range of functionalities, the PocketBook remains a dedicated option for those who primarily want an e-reader experience.
Battery Life
In terms of battery life, the PocketBook Era boasts an impressive battery that can last up to one month on a single charge, making it a strong contender for avid readers who don't want to frequently recharge. The Bigme B7, while not explicitly stated, features a 3000 mAh battery, which may not provide the same longevity given its additional functionalities that likely consume more power. For users who prioritize long reading sessions and minimal interruptions, the PocketBook's battery performance is a crucial advantage.
Storage Capacity
Storage capacity is another area where these two devices differ significantly. The Bigme B7 offers a generous 128GB of internal storage alongside expandable options via microSD, catering to users who need ample space for documents, apps, and media. Meanwhile, the PocketBook Era provides 32GB of internal memory, which is still substantial for ebooks and audiobooks but doesn't match the extensive storage of the Bigme. For those who plan to store a large library of content, the Bigme clearly has the upper hand.
Audio Features
Audio features play a significant role in the overall user experience of these devices. The PocketBook Era is equipped with built-in speakers and Bluetooth capabilities, allowing users to listen to audiobooks and music, as well as utilize the text-to-speech function that transforms ebooks into spoken word. In contrast, the Bigme B7 does not highlight any audio capabilities in its features, making the PocketBook a better choice for those who enjoy listening to content. The audio functionalities of the PocketBook enhance its appeal as a multi-purpose device.
Connectivity Options
Connectivity is a strong suit for both devices, yet they cater to different needs. The Bigme B7 excels with its built-in 4G connectivity, allowing for web browsing and app usage without Wi-Fi, making it ideal for users on the go. In comparison, the PocketBook Era offers Wi-Fi connectivity along with various syncing options like PocketBook Cloud and Dropbox, facilitating easy content management. While the Bigme enables more extensive connectivity, the PocketBook's options are more tailored for users focused solely on their reading experience.
Price Comparison
The pricing of these devices reflects their respective features and functionalities. The Bigme B7 Color ePaper Tablet is currently priced at $289.00, while the PocketBook Era Color Ereader comes in at $269.00, making it about 7% cheaper. The difference in price can be attributed to the additional functionalities offered by the Bigme, such as 4G calling and a more extensive storage capacity. For budget-conscious consumers, the PocketBook presents a more economical choice, especially for those who are primarily interested in reading.
Which should you buy?
Deciding between the Bigme B7 Color ePaper Tablet and the PocketBook Era Color Ereader ultimately depends on your specific needs. If you're looking for a versatile device that combines the features of a tablet and an e-reader, the Bigme B7 is a compelling option with its extensive storage and 4G capabilities. However, if you prioritize a dedicated reading experience with excellent display quality and long battery life, the PocketBook Era is the better choice. It provides a more focused approach to reading with added audio features, making it ideal for those who enjoy audiobooks. Consider your primary use case to make the best decision tailored to your reading habits.
