Screen
The 10.3" color E Ink panel sits around 300 PPI, includes a front light, and adds warm light. In practice, that makes it lean toward manga, illustrations, and interface layers.

Reading Experience
Battery
The quoted battery life is around 9 weeks, which usually means you can treat charging as a weekly or biweekly habit rather than a daily chore. The battery pack is about 3700 mAh.
Page-Turn Speed
Page turns feel more like a productivity device: good enough, but not tuned for absolute speed.
Who Should Buy It
- People who want manga, diagrams, or textbook illustrations without going back to an LCD tablet.
- People who need direct markup for PDFs, classes, or meeting notes.
- Buyers who are willing to spend more for a more specific reading or note-taking workflow.

Verdict
If you only read one conclusion: BOOX Note Air4 C is not trying to be everything, but it is coherent inside its core job: note-taking and heavier document work. If that job matches the way you actually read, it is easy to justify; if you need a larger canvas, a richer app ecosystem, or a more aggressive value play, the alternatives and comparison links below are the right next step.
