Dimension comparison
Display Quality
The Bigme B7 Pro Color e-Reader boasts a 7-inch 300PPI E-ink Kaleido 3 display, while the PocketBook Basic Lux 4 features a 6-inch HD E Ink Carta display. The Bigme's larger display provides a true paper reading experience with vivid colors and reduced eye strain, making it ideal for long reading sessions. The PocketBook's glare-free screen is designed for comfort in various lighting conditions, but its smaller size may limit the overall reading experience. Ultimately, if display quality and size are paramount to you, the Bigme B7 Pro stands out with its advanced technology.
Performance
When it comes to performance, the Bigme B7 Pro is powered by an upgraded MediaTek Dimensity 1080 Octa-core processor combined with 8GB of RAM, ensuring smooth operation across tasks. In contrast, the PocketBook Basic Lux 4 does not specify its processor but is designed for basic reading functionalities. The Bigme's advanced specs enable it to handle a wider range of applications and tasks, including video and animation playback. For users looking for more than just reading, the Bigme provides significantly better performance.
Storage Capacity
The Bigme B7 Pro offers an impressive 256GB of internal storage, allowing users to store approximately 160,000 books and even supports microSD expansion up to 2TB. Conversely, the PocketBook Basic Lux 4 comes with 8GB of internal memory and also features microSD support. While the PocketBook offers decent storage for casual readers, the Bigme's massive capacity is advantageous for avid readers or those who prefer to have a vast library on hand. If storage is a critical factor for you, the Bigme B7 Pro is the clear winner.
Battery Life
The Bigme B7 Pro promises long battery life, allowing users to enjoy reading for weeks on a single charge, although specific battery duration is not stated. The PocketBook Basic Lux 4 also claims a long-lasting battery that can last for days with regular reading habits. While both devices emphasize battery longevity, the Bigme's extended use period gives it a slight edge for those who often read on the go or travel frequently.
Connectivity Options
The Bigme B7 Pro is equipped with 4G global connectivity, allowing users to stay connected anywhere with a compatible SIM card. This feature is complemented by Wi-Fi and Bluetooth capabilities. On the other hand, the PocketBook Basic Lux 4 only offers Wi-Fi connectivity. For users who need constant internet access without relying solely on Wi-Fi, the Bigme's 4G capability makes it a more versatile option.
Design and Portability
Weighing in at just 155 grams and measuring 8 mm thin, the PocketBook Basic Lux 4 is extremely lightweight and designed for easy portability. The Bigme B7 Pro, while larger and heavier due to its 7-inch display, still maintains a manageable weight for an e-reader. If you prioritize a compact design for easy transport, the PocketBook would be preferable. However, if you value a larger display for a better reading experience, the Bigme is worth the trade-off.
Price Point
The Bigme B7 Pro is priced at $427.49, making it significantly more expensive than the PocketBook Basic Lux 4, which costs $119.00. This price difference of about 259% reflects the advanced features and capabilities of the Bigme, such as its larger display, superior performance, and extensive storage. For those on a budget or seeking a straightforward e-reader for basic reading needs, the PocketBook offers excellent value. However, if you're looking for a more powerful device that can perform multiple functions, the investment in the Bigme may be justified.
Which should you buy?
Choosing between the Bigme B7 Pro Color e-Reader and the PocketBook Basic Lux 4 ultimately depends on your reading habits and needs. If you seek a high-performance, feature-rich e-reader with superior display quality, extensive storage, and connectivity options, the Bigme B7 Pro is an excellent choice despite its higher price. However, if you prefer a lightweight device for simple reading without breaking the bank, the PocketBook Basic Lux 4 is a solid option that offers essential features at a very attractive price.
