Product Overview
NuPhy Air75 V2 is a low-profile wireless mechanical keyboard built around an ANSI 75% layout, 84 keys, Gateron low-profile mechanical switches, hot-swappable sockets, QMK/VIA support, and three connection modes: 2.4GHz, Bluetooth 5.1, and USB-C wired.
What Stands Out
Open this if you want mechanical-keyboard feel in a laptop-friendly form. Air75 V2 keeps hot-swap switches, QMK/VIA customization, and multi-device wireless while staying thin enough for compact desks and bags.
Why It Matters
Air75 V2 shows a different path from heavy custom keyboards: it keeps mechanical switches and firmware customization while making the keyboard thin, light, and easier to move between a laptop, desk, and travel setup.
Best For
Laptop users, compact desks, and travelers who want real mechanical switches without a tall custom-keyboard body.
Not For
Not the best fit for users who want a full-height custom keyboard feel, a number pad, an all-metal case, or a keyboard focused only on silent office typing.
Things to Know
Official specs list an aluminum frame with an ABS bottom case, not a full aluminum body.
Air75 V2 supports 2.4GHz, Bluetooth 5.1, and USB-C wired modes; official specs list 1000Hz polling in 2.4GHz and wired modes.
Battery life depends heavily on lighting. Official lab results list 35-57 hours with all lights on and up to 220 hours with lights off.
