Third-party reviews

What we like about Onyx Boox Volta 3

  • Android-based OS allows for high flexibility and the installation of third-party apps
  • Equipped with a self-lit e-paper display featuring anti-reflection coating for comfortable reading in various lighting conditions
  • Features a 3000 mAh rechargeable battery, which is substantial for a 6-inch e-reader
  • Includes modern USB Type-C connectivity for charging and data transfer
  • Highly portable 6-inch form factor that is easy to hold for extended periods

What we don't like about Onyx Boox Volta 3

  • Lower screen resolution of 212 PPI (758 x 1024) compared to the 300 PPI standard found in higher-end models like the Onyx Boox Page
  • Lacks damage-resistant glass (such as Gorilla Glass), making the E Ink screen more vulnerable to physical damage
  • Android OS can lead to significant battery drain if Wi-Fi or high-refresh modes are used constantly
  • The out-of-the-box user experience may be complex or 'un-streamlined' for users accustomed to simpler devices like Kindles
  • No built-in wireless charging support

Verdict

The Onyx Boox Volta 3 is a compact 6-inch e-reader featuring an E Ink Carta display with a resolution of 758 x 1024 (212 ppi) and a flicker-free Moon Light 2 system with adjustable color temperature. Powered by a 1.2 GHz quad-core processor, 512 MB of RAM, and 8 GB of internal storage expandable via microSD, it runs on Android 4.4, providing flexibility for third-party apps and supporting over 20 file formats. Its main advantages include a lightweight 160g ergonomic design, a high-capacity 3000 mAh battery for extended use, and a specialized protective cover with physical side-scrolling buttons. However, its downsides include an outdated Android version, limited RAM that may cause lag during multitasking, and a relatively low pixel density compared to higher-end 300 ppi models.
