Dimension comparison
Overview
When comparing the Bigme B7 Color ePaper Tablet and the PocketBook Era Color Ereader, a significant distinction lies in their functionalities and target audiences. The Bigme B7 is priced at $289.00, while the PocketBook Era is slightly cheaper at $269.00, making it about 7% less expensive. This price difference reflects their unique features and intended uses, catering to different reading preferences and tech needs.
Display Quality
The display quality of these two e-readers is a crucial aspect to consider. The Bigme B7 features a 7-inch color ePaper display, allowing for vibrant visuals and a smooth reading experience. This device is tailored for users who appreciate a more tablet-like experience, enhanced by its Android OS. In contrast, the PocketBook Era also sports a 7-inch display but utilizes the Kaleido 3 screen technology, which excels in delivering sharp black-and-white text alongside vivid colors. This technology is particularly beneficial for reading ebooks, comics, and magazines, emphasizing a paper-like reading experience tailored for book enthusiasts.
Connectivity Options
Connectivity is another area where the Bigme B7 stands out. It offers 4G connectivity and call support, allowing users to browse the web and make voice calls without needing Wi-Fi. This feature makes it an excellent choice for those who want a versatile device that combines the functions of a tablet and a phone. On the other hand, the PocketBook Era focuses on more traditional e-reader connectivity options, featuring Wi-Fi for cloud syncing and USB-C for file transfers. While it lacks cellular capabilities, it still includes Bluetooth, enabling users to connect wireless headphones for audio content.
Storage Capacity
In terms of storage, the Bigme B7 comes equipped with 128GB of internal storage, which is significantly higher than the PocketBook Era's 32GB. This substantial difference makes the Bigme B7 a better option for users who need ample space for apps, documents, and media files. Additionally, the Bigme device allows for further expansion via microSD, accommodating those who often store large files. In contrast, while the PocketBook Era's storage may be adequate for many readers, it may limit users who enjoy a diverse library of ebooks and audiobooks.
Battery Life
Battery life is a vital consideration for e-reader users. The PocketBook Era boasts an impressive battery longevity of up to one month on a single charge, making it a reliable companion for avid readers who may not want to worry about frequent recharging. The Bigme B7’s battery capacity of 3000 mAh is not specified in terms of usage duration, but the dual functionality of being a tablet and phone likely consumes more power. Therefore, the PocketBook Era may have the advantage in this department, providing a longer-lasting reading experience without the need for constant charging.
Additional Features
When it comes to additional features, both devices offer unique functionalities that cater to different user needs. The Bigme B7 is designed with enhanced productivity in mind, featuring a magnetic stylus for note-taking and document annotation, making it suitable for students and professionals alike. It allows for seamless multitasking thanks to its octa-core processor. In contrast, the PocketBook Era emphasizes its audiobook capabilities, featuring built-in speakers and a Text-to-Speech function that transforms text into spoken word, making it an excellent choice for those who enjoy audiobooks alongside traditional reading.
Design and Build Quality
Design and ergonomics play a crucial role in the overall user experience. The Bigme B7's design leans towards a tablet aesthetic, which may appeal to users accustomed to modern tech devices. Its dimensions and weight, however, are not specified, making it difficult to judge its portability. The PocketBook Era, though also undisclosed in weight, is designed with an IPX8 waterproof rating, ensuring it can withstand splashes and immersion in water. This feature adds to its durability, making it a practical choice for reading in various environments, such as by the pool or at the beach.
Which should you buy?
In conclusion, the choice 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 tablet and calling capabilities, along with ample storage, the Bigme B7 is the better option despite its higher price tag. However, if you prioritize a dedicated e-reader with excellent battery life, waterproof features, and a focus on audiobooks, the PocketBook Era presents a compelling alternative at a lower price point.
