Onyx Boox Note Air4

The Kaleido 3 color ePaper display uses E Ink technology, which is reflective rather than backlit like an LCD or OLED screen. This makes it much easier on the eyes for long reading sessions and note-taking, though the colors are more muted and have a lower resolution than a traditional tablet.

The device features a textured screen surface designed to provide tactile feedback and friction, mimicking the feel of writing on paper. Combined with the responsive Pen Plus, it offers a natural, low-latency experience suitable for sketching and long-form writing.

Yes, the Note Air4 C includes a microSD card slot, allowing you to easily expand the 64GB of internal storage to accommodate large libraries or extensive note archives.

Yes, the device is equipped with a fingerprint lock, allowing you to secure your data and prevent unauthorized access to your notes and personal files.
