BOOX Tablet Note Air 4 C E Ink Tablet Color ePaper Notebook - Color

Our review of the BOOX Tablet Note Air 4 C finds it aimed at people who want a paperlike writing experience with color ePaper for notes and light media. The single biggest reason to consider it is the 10.3' Kaleido 3 color Carta 1200 screen paired with a pressure sensitive stylus, which together make handwriting and sketching feel precise and natural while still supporting readable black and white text at 300 ppi. It is not a cheap device, so buyers should expect premium hardware and Android flexibility in exchange for a higher price.

Key Features

• 10.3' Kaleido 3 color display: Offers a color ePaper layer over Carta 1200 glass so drawings and annotations render in up to 4,096 colors while preserving the low-glare, paperlike look.
• High-resolution text: The Carta 1200 layer delivers 2480 x 1860 at 300 ppi in black and white for crisp PDFs, ebooks and documents.
• Responsive stylus input: The BOOX stylus with 4,096 levels of pressure sensitivity makes handwriting and shading feel accurate for note taking and sketches.
• Android 13 and app support: Runs Android 13 so third-party apps can be installed for reading, productivity and audio without being locked to a single ecosystem.
• Solid hardware package: Octa-core CPU, 6 GB RAM and 64 GB storage give enough performance and space for large document libraries and multiple apps.
• Convenience features: Fingerprint power button, USB-C with OTG, microSD slot, dual speakers and front light with warm and cold CTM improve daily use.

Who It's For

The BOOX Note Air 4 C is best for students, professionals and creatives who prioritize handwriting quality and need a device that handles PDFs, ebooks and annotations reliably; the combination of a high-resolution B/W layer and a Kaleido color layer is especially useful for annotating diagrams and drafting colored sketches. It also suits users who want Android flexibility to run third-party reading and note apps rather than a closed reader ecosystem.

Those who should look elsewhere include buyers on a tight budget or heavy media consumers who expect fast full-color video playback; the color ePaper excels for static images and notes but does not replace an LCD or OLED tablet for high-frame-rate multimedia or the lowest cost per feature.

Pros & Cons

Pros

• Natural, paperlike writing thanks to the stylus with 4,096 pressure levels and a flat cover-lens.
• Strong document readability with 300 ppi B/W resolution and broad format support including PDF and EPUB.
• Flexible Android 13 platform with Wi-Fi, Bluetooth 5.1 and expandable storage for apps and files.
• Convenience extras such as fingerprint power, USB-C OTG and built-in speakers add practical value.

Cons

• Some users find the device expensive relative to simpler eReaders and single-purpose note devices.
• Color performance is useful for static content but has lower color resolution (150 ppi) than the B/W layer.

Our Verdict

Is the color screen good for photos?
