NuPhy Air75 V3: Specs, Features, Pros & Cons
The Air75 V3 is the flat member of NuPhy's range, the low-profile counterpart to the taller Halo75 V2 in the same compact layout. It keeps the function row and a proper arrow cluster, drops the number pad, and puts low-profile mechanical switches under keycaps so low that the board rests at about the height of a laptop deck.
Low-profile mechanical boards usually give up the enthusiast details, and this one keeps most of them. The case is gasket-mounted, the keycaps are PBT, the switches sit in hot-swap sockets, and every key registers when several are held. Programmable keys and media shortcuts come as standard, and the lighting is RGB. A rotary knob comes as two swappable modules, one tall and one low, for volume, zoom or any other two-way control. The name marks the third generation of the design.
Its build is also meant to travel. An aluminum top over a plastic base keeps it light, and the low profile lets it share a bag with a laptop. NuPhy rates the battery with all lighting off, and its own lights-on figure is a small fraction of that, so the RGB decides whether charging is an occasional chore or a regular one. The gaming side is ordinary. Polling runs at the usual rate, and there is no magnetic sensing, no rapid trigger and no adjustable actuation, so it plays games competently without chasing the players who buy on those features.
Everything turns on the low profile: flat keys suit people who type on a laptop all day and want the same hand position at a desk, and they can frustrate typists raised on tall keyboards. The ideal buyer writes for a living, works from more than one place, and has already found that low-profile keys agree with their hands.

How this VS Score was computed
Score 64: each known spec is measured against the median of all keyboards (101 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 46% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
The Air75 V3 solves a problem most mechanical keyboards ignore: they are too tall to type on comfortably without a wrist rest.
At a rated 13.2 mm thick this one sits close to the height of a laptop keyboard, yet NuPhy rates its nano switches at 3.5 mm of travel and says they go as deep as full-height switches. Your wrists stay flat, which over a working day matters more than any switch specification. At 724 g with an aluminum top and ABS bottom it is also portable.
The rest of the build is more serious than the profile suggests: a gasket mount with a polycarbonate plate, hot-swappable switches (rare on low-profile boards, where the sockets are harder to fit) and PBT keycaps in a 75% layout with a function row and arrow keys.
The 4,000 mAh battery carries the big number, rated for up to 1,200 hours with all lights off and 60 to 100 hours with all lights on, both lab results, and Bluetooth pairs with three devices. The lighting decides how often it goes on the cable.
There is no Hall-effect sensing, no rapid trigger and no analog input, and polling is 1,000 Hz over the cable and the 2.4 GHz dongle. This is a typing keyboard that games adequately, not the reverse.
Buy it if you want a slim, portable, long-lasting mechanical keyboard and low-profile switches suit you. Try them first if you have not, because the low, flat keys divide people sharply. Buy a full-height board if you already know you prefer taller keys.

The bottom line
The NuPhy Air75 V3 earns a VS Score of 64, above the median of the 101 keyboards it is measured against (a score of 50 is level with that median).
- Who it’s for
- Someone who types most of the day, dislikes wrist rests, and wants a mechanical board thin and light enough to carry with a laptop.
- Who should look elsewhere
- If you already know you prefer a full-height board, or you are shopping for rapid trigger and magnetic sensing, buy a different board.
- The trade-off that matters
- The low profile keeps wrists flat and the board slim, but typists used to full-height boards may need time to adjust to the flat keycaps, so try one before committing.
- The main alternative
- NuPhy Halo75 V2: NuPhy's standard-height board in the same layout, for typists who want full-height switches and keycaps.
