NuPhy Air75 V3 Review: Is This NuPhy’s Best Low-Profile Keyboard Yet?
If you’ve been eyeing a low-profile mechanical keyboard and keep landing on NuPhy‘s Air lineup, the newest Air75 V3 is worth a proper look before you commit. It’s priced at $139.95, currently holds a 4.7-star rating across 333 reviews on NuPhy’s own site, and — according to NuPhy’s published lab testing — battery life jumped from roughly 220 hours on the Air75 V2 to as much as 1,200 hours on this V3 model with the lighting off. Here’s what’s actually different, what’s in the box, and who this keyboard makes sense for.
What Is the NuPhy Air75 V3?
The Air75 V3 is a 75% layout wireless mechanical keyboard from NuPhy’s Air series, built around low-profile switches and an aluminum top case. It’s part of the newer “V3” generation NuPhy is currently promoting alongside the Air65 V3 and Air100 V3, and it’s designed to work across macOS, Windows, Android, and iOS. The keyboard measures 318.9 x 128.9 x 13.2 mm and weighs about 724 grams (1.6 lb), with 84 keys in an ANSI layout (JIS and ISO-DE/UK/FR layouts are also offered).
Key Features and What’s New in the V3
A Dramatically Longer Battery
This is the headline change. NuPhy’s own lab comparison shows the Air75 V3’s 4,000 mAh battery lasting up to 1,200 hours with the RGB lighting off, compared with roughly 220 hours on the Air75 V2 and 100 hours on the original Air75. With backlighting on, NuPhy lists working time at 60–100 hours. It charges over USB-C.

Deeper Switch Travel, Same Slim Profile
NuPhy states the low-profile switches on the V3 now travel as deep as high-profile switches, while the case itself stays thin — listed at 13.2 mm tall. The keyboard ships hot-swappable, so you can pull the pre-installed switches and try others without soldering.
A Functional Rotary Knob
The Air75 V3 includes a rotary knob that can be mapped to volume, scrolling, or other functions, and the box includes both a high-profile and a low-profile knob module so you can choose whichever sits better with your typing height.
Gasket-Mounted for a Softer Feel
The keyboard uses a gasket-mounted plate with plate-mounted stabilizers, a PC plate, and double-shot PBT keycaps — build details more commonly found on enthusiast custom keyboards than off-the-shelf ones.
Adjustable Typing Angle
A 3-stage kickstand lets you set the typing angle at 4°, 8°, or 10°, and North-facing RGB LEDs run underneath with 20 backlight modes.

Three Ways to Connect
The Air75 V3 connects over 2.4GHz wireless, Bluetooth 5.0, or wired via USB-C, with a 1,000Hz polling rate on both the 2.4GHz and wired connections (Bluetooth polls at 125Hz).
Switch and Layout Options
At checkout, NuPhy offers three low-profile switch options — Blush nano (currently marked as the best seller), Red nano, and Brown nano — plus five layout options: ANSI US English, JIS Japanese, and ISO German, British, or French. The unit referenced in this review is finished in Nova White.
Who Is the Air75 V3 Built For?
Based on how NuPhy positions the Air75 V3, it fits:
- People who want a slim, portable mechanical keyboard for a Mac or Windows desk setup
- Typists who want to try hot-swappable switches without buying a full custom keyboard kit
- Anyone tired of charging their keyboard every week — the extended battery life is the headline upgrade of this generation
- Buyers who want extras like a working knob, adjustable kickstand, and RGB lighting on top of a compact 75% layout
Pros and Cons
Pros:
- Battery life rated up to 1,200 hours with RGB off — a major jump over the previous generation
- Hot-swappable low-profile switches with a choice of three factory options
- Gasket-mounted build with an aluminum top case and PBT keycaps at this price point
- Works across macOS, Windows, Android, and iOS with three connection modes
- 4.7-star average from 333 reviews on NuPhy’s site
Cons:
- At $139.95, it costs more than many mainstream low-profile keyboards without mechanical switches
- Bluetooth polling rate (125Hz) is noticeably lower than the 2.4GHz/wired modes (1,000Hz)
What’s in the Box
Every Air75 V3 ships with: the keyboard, a USB-C to USB-C cable, a high-profile knob module, a low-profile knob module, a 2.4GHz USB dongle, a screwdriver, a keycap/switch puller, a user manual/FAQ download link, and a small set of extra keycaps (the exact count varies by layout).
Pricing and Current Offer
The NuPhy Air75 V3 is listed at $139.95 USD. At the time of writing, NuPhy is also including a free Summer Keycaps set with purchase as a limited-time offer — worth confirming on the product page since bundled gifts like this typically rotate or expire. NuPhy also sells optional add-ons for the Air75 V3, including the NuFolio case ($29.95), a wrist rest, and desk mats. Every purchase is backed by a 1-year warranty.
Air75 V3 vs. Air75 V2: What Actually Changed
Based on NuPhy’s published specs, the clearest difference between generations is battery life — up to 1,200 hours on the V3 versus roughly 220 hours on the V2, both measured with RGB off under lab conditions. NuPhy also states switch travel is deeper on the V3 while the case keeps the same slim height, and the V3 adds the swappable knob module system. NuPhy has not published a full spec-by-spec V2-vs-V3 comparison beyond these highlighted differences, so shoppers comparing finer details should check both product pages directly before deciding.
