Verdict
The Onyx Boox M92 suits comics, reports and annotated documents on its big 9.7-inch screen, but its browser is weak and it ships without a cover.

Third-party reviews

What we like about Onyx Boox M92

  • Excellent PDF handling with advanced features like 'hide margins' and selection zoom
  • Large 9.7-inch E Ink display ideal for technical, academic, and A4/Letter sized documents
  • Versatile physical controls including a navigation wheel, page-turn buttons, and a joystick for font sizing
  • Extensive hardware connectivity with a full-size SD card slot and 3.5mm headphone jack
  • Open-source friendly, allowing for community-driven firmware and software fixes
  • Includes Wacom touchscreen support with a stylus for on-screen notes

What we don't like about Onyx Boox M92

  • Outdated hardware design with a plastic back that easily shows fingerprints
  • Lack of a built-in storage slot for the stylus on the device itself
  • Inconsistent software experience with bugs like overlapping page numbers and limited margin settings in some apps
  • Limited multitasking capabilities, requiring users to close one application before opening another
  • Relatively low pixel density (150 ppi) compared to modern e-readers
  • Frequent Wi-Fi connectivity issues and slow web browsing performance

Verdict

The Onyx Boox M92 is a large-format 9.7-inch e-reader featuring an E Ink Pearl display with a 1200 x 825 resolution (150 ppi) and 16 levels of grayscale. Powered by an 800MHz Freescale i.MX 508 processor and 256MB of RAM, it includes 4GB of internal storage expandable via a full-size SDHC slot (up to 32GB) and a 1600mAh battery capable of up to 8,000 page turns per charge. Main characteristics include a Wacom electromagnetic touchscreen for stylus-based navigation and note-taking, alongside physical controls like a 5-way joystick and dedicated page-turn buttons. Its primary pros are the spacious screen ideal for A4 PDF reading, extensive support for over 28 file formats (including ePub, DjVu, and MOBI), and built-in audio features like a 3.5mm jack and speaker for MP3s or text-to-speech. However, notable cons include its relatively heavy 520g weight, a dated plastic design prone to fingerprints, and occasional Wi-Fi connectivity issues.
