The Note Air5 C offers one of the best writing experiences I've had.
using the physical keyboard is slow and makes touch typing difficult
the 3,700mAh battery doesn't last very long as Android is a power-hungry OS
the visual transitions are the best I've ever seen on a Boox device.
you get one of the most refined note-taking experiences on a digital notebook.
The pressure detection isn't quite in the same league as those you get with Wacom or the Apple Pencil Pro

Schema note: the named e-ink-tablets.json does not exist in the repo; specKeys and methodology were taken from data/products/e-readers.json, which already holds the sibling Boox Note Air4 C. The official BOOX store product page (shop.boox.com/products/noteair5c) confirmed verbatim the 10.3" Kaleido 3 (4,096-color) screen at B/W 2480 x 1860 (300 ppi), 6 GB RAM / 64 GB ROM, Android 15, a "Front Light with CTM (Warm and Cold)" (warm_light=true), a 3,700 mAh Li-ion Polymer battery, and the BOOX Pen3 stylus listed in "Included In The Box (standard only)" (stylus_included=true); the only button in the hardware spec is the "Power Button with Fingerprint Recognition" and no IP water rating is listed anywhere, so page_turn_buttons=false and waterproof=false. That page's comparison table lists the Note Air5 C at "$499.99 Order Now" (vs. Note Air4 C $469.99 and Tab X C $759.99), giving the price. The Wikipedia Onyx Boox device table corroborates the exact Note Air5 C row — October 2025 launch, Android 15, Snapdragon 690, 6 GB RAM, 64 GB storage, 10.3" (2480×1860) Kaleido 3, predecessor Note Air4 C — confirming model identity as the Note Air5 C (not the Note Air4 C or Tab X C). No battery life in weeks appears on either page, so battery_weeks is null.
