Dimension comparison
Design and Display Quality
Both the Bigme B7 Color ePaper Tablet and the PocketBook Era E-Reader feature 7-inch displays, but their technologies cater to different preferences. The Bigme B7 utilizes a color ePaper screen, which allows for vibrant images and a more versatile use case as a tablet, while the PocketBook Era boasts a glare-free E-Ink Carta 1200 screen that significantly enhances contrast and touch responsiveness. With a 15% increase in image contrast and a 20% boost in touch response time, readers can easily enjoy their favorite books even in bright sunlight.
Features and Functionality
The Bigme B7 Color stands out with its 4G connectivity and calling support, allowing users to browse the web, use apps, and make voice calls without needing a Wi-Fi connection. This feature transforms the device into a multifunctional tool, combining the capabilities of a tablet and a phone. Meanwhile, the PocketBook Era focuses on reading, offering waterproof capabilities with an IPX8 rating, which allows it to be submerged in water up to 2 meters. Both devices cater to different user needs, with the Bigme B7 prioritizing versatility and the PocketBook Era emphasizing enhanced reading experiences.
Storage and Memory
In terms of storage, the Bigme B7 Color offers a significant advantage with 128GB of internal storage, expandable via microSD, making it ideal for users who need ample space for documents, apps, and media. In contrast, the PocketBook Era provides 16GB of storage, enough for a substantial number of eBooks but likely inadequate for those who wish to store other types of content. This difference highlights the Bigme B7's capability to support more extensive multimedia use, while the PocketBook Era is more focused on eBook reading.
Audio and Multimedia Features
The audio capabilities of these devices differ significantly. The PocketBook Era includes a built-in speaker and a Text-to-Speech function that can read aloud text files in 26 languages, making it a great choice for users who enjoy audiobooks or need accessibility features. On the other hand, the Bigme B7, while it supports multimedia, does not emphasize audio features to the same extent. Therefore, users who value audio functionality may find the PocketBook Era to be the better option.
Battery Life
Battery life is crucial for e-readers, and both devices promise longevity, albeit under different usage scenarios. The PocketBook Era boasts a long-lasting battery that can last up to a month on a single charge, which is particularly beneficial for avid readers who may not want to charge their device frequently. The Bigme B7 has a 3000 mAh battery, but specific longevity details are not provided. If battery endurance is a primary concern, the PocketBook Era's performance in this area may be more appealing to potential buyers.
Price Comparison
When considering price, the Bigme B7 Color is available for $289.00, while the PocketBook Era is priced at $249.00, making the PocketBook Era about 17% cheaper. This price difference may influence budget-conscious consumers, particularly those who primarily seek an e-reading experience without the additional functionalities offered by the Bigme B7. The Bigme B7's price reflects its multifunctionality, but for those focused solely on reading, the PocketBook Era offers a more economical choice.
Bestseller Ranking
Both devices have established themselves in the market, with the Bigme B7 Color holding a sales rank of 37,595 and the PocketBook Era slightly ahead at 30,379. While neither is a top seller, the PocketBook Era's higher rank indicates a stronger preference among users, possibly due to its dedicated features for reading and audiobook support. This ranking can serve as a guide for consumers looking for popular options within the e-reader category.
Which should you buy?
Choosing between the Bigme B7 Color ePaper Tablet and the PocketBook Era E-Reader ultimately depends on your specific needs. If you seek a versatile device that functions as both a tablet and an e-reader with extensive storage, the Bigme B7 would be the right choice for you. However, if you prioritize a dedicated reading experience with excellent audio features, a glare-free display, and waterproof capabilities at a lower price point, the PocketBook Era is likely the better option.
