What we like about Onyx Boox Nova Air C

  • Versatile Android 11 system with full access to the [Google Play Store](Use code with caution.Copied to clipboardjsonhttps://www.androidcentral.com/tablets/onyx-boox-nova-air-c-reviewUse code with caution.Copied to clipboardjson) for apps like Kindle, Outlook, and Chrome.
  • Premium, slim, and lightweight build quality (235g) that is highly portable for one-handed use.
  • Excellent writing and note-taking experience with the included Wacom stylus, featuring 4,096 levels of pressure sensitivity and low latency.
  • Innovative color E Ink (Kaleido Plus) screen that is great for viewing book covers, charts, and manga compared to monochromatic displays.
  • Comprehensive reading software (Neo Reader) with advanced features like split-screen, text-to-speech, and extensive image controls.
  • Includes both warm and cold front lights (Moon Light 2) for comfortable reading in various lighting conditions.

What we don't like about Onyx Boox Nova Air C

  • Significantly shorter battery life (approx. 2000mAh) compared to dedicated e-readers like Kindles, often requiring charging every 1-2 days with heavy use.
  • Muted and 'washed out' color quality that can appear grainy or dark without the front light turned on.
  • Noticeable ghosting and poor refresh rates for video playback or fast-scrolling third-party apps.
  • Limited 32GB internal storage with no MicroSD slot for expansion, which may be insufficient for large color media libraries.
  • Small 7.8-inch screen size is not ideal for reading or annotating large A4-sized PDF documents.
  • High price point ($420) puts it in competition with more powerful traditional tablets like the iPad Mini.

Verdict

The Onyx Boox Nova Air C is a versatile 7.8-inch color e-reader featuring an E Ink Kaleido Plus On-Cell Touch display that delivers 300 ppi for black-and-white text and 100 ppi for 4,096 colors. It is powered by a Qualcomm Snapdragon 662 octa-core processor, 3GB of LPDDR4X RAM, and 32GB of internal storage, all running on the Android 11 operating system with full Google Play Store access. Main pros include its slim 6.3mm metal body, a lightweight 235g design, and an included Wacom-layer stylus with 4,096 levels of pressure sensitivity for responsive note-taking, alongside a dual-tone Moon Light 2 front-lit system. However, notable cons include a relatively small 2,000mAh battery that can drain quickly with heavy use, the lack of a microSD card slot for storage expansion, and muted color vibrancy compared to standard LCD or OLED tablets.
