Display Quality

The Bigme B7 Color eReader features a 7-inch E ink Kaleido 3 display with a resolution of 300 PPI, delivering vibrant colors and clear text. In contrast, the Kobo Clara BW has a 6-inch E Ink Carta 1300 HD display that is glare-free but only supports black and white reading. This difference in display technology means that the Bigme offers a more visually engaging reading experience, especially for content with images or colorful layouts. The Bigme’s advanced display enhances reading comfort, claiming to provide zero blue light and flicker-free viewing, which is essential for long reading sessions.

Storage Capacity

The Bigme B7 Color eReader comes with a substantial storage capacity of 128GB, allowing users to store approximately 70,000 books. This is particularly advantageous for avid readers and those who prefer to carry an extensive library. On the other hand, the Kobo Clara BW has a more limited storage capacity of 16GB, which can hold up to 12,000 eBooks or 75 audiobooks. Therefore, those who prioritize having a larger library readily available may find the Bigme B7 to be a more suitable choice.

Price Comparison

The Bigme B7 Color eReader is priced at $319.97, while the Kobo Clara BW is significantly cheaper at $139.99, making it about 56% less expensive. This price difference could be a decisive factor for budget-conscious consumers or those new to e-readers who may not want to invest heavily at the outset. However, the higher price of the Bigme is reflective of its advanced features and capabilities, which could justify the cost for more serious users.

Battery Life and Usage

The Bigme B7 Color eReader boasts a long battery life that can last for weeks, making it ideal for users who read extensively without frequent charging. The Kobo Clara BW also claims to offer weeks of battery life, but with less demanding usage scenarios. The difference lies in the additional functionalities of the Bigme, such as 4G calling and a more powerful CPU, which may require more frequent charging under heavy use. Thus, for users who engage in intensive activities beyond reading, the Bigme’s battery longevity may be a significant advantage.

Additional Features

The Bigme B7 Color eReader includes features like 4G calling support, a wireless charging stylus, and the ability to record notes, enhancing its versatility as a digital tool beyond just reading. It runs on Android 14, allowing for third-party app support, which can significantly extend its functionality. In contrast, the Kobo Clara BW focuses primarily on reading, with features like ComfortLight PRO for adjustable brightness, but it lacks the multifunctionality of the Bigme. This makes the Bigme a better choice for users looking for an all-in-one device.

Design and Portability

The Bigme B7 Color eReader, with its 7-inch design, is slightly larger than the Kobo Clara BW's 6-inch screen. While both devices are portable, the Kobo’s smaller size may be more convenient for users who prioritize compactness. However, the Bigme’s larger display enhances the reading experience, especially for visual content. Both devices are designed for comfortable reading, but users may prefer the Kobo's lighter, smaller design for portability, especially when traveling.

Waterproofing

The Kobo Clara BW stands out with its IPX8 waterproof rating, meaning it can withstand being submerged in water for up to 60 minutes at a depth of 2 meters. This feature makes the Kobo an excellent choice for readers who enjoy reading by the pool or in the bath. The Bigme B7 does not list any waterproof capabilities, which could be a drawback for users concerned about water exposure. For those who frequently read in wet environments, the Kobo Clara BW offers a significant advantage.

Which should you buy?

Choosing between the Bigme B7 Color eReader and the Kobo Clara BW largely depends on your specific needs and reading habits. If you prefer a multifunctional device with extensive storage, vibrant color displays, and advanced features like note-taking and 4G calling, the Bigme B7 is your best bet despite its higher price. However, if you are looking for a budget-friendly e-reader that excels in portability and waterproofing, the Kobo Clara BW is a fantastic option. Ultimately, consider how you plan to use your e-reader and select the one that best aligns with your lifestyle and preferences.
