NuPhy Air75 V3 Officially Revealed: Thin, Light, Long-Travel Switches, and Surprisingly Long Battery Life

The wireless mechanical keyboard market is witnessing a fierce race, where companies are constantly improving both design and features to win the love of users. And in that game, NuPhy - a name that is already familiar to the technology and creative community continues to affirm its position with the all-new Air75 V3 model.

This is not just a simple upgrade. The Air75 V3 is NuPhy's strong response to formidable competitors like the Iqunix Magi65 Pro or Lofree Flow Lite, names that have gradually surpassed the previous Air line thanks to modern gasket mount technology and smooth, thin, light switches.

With an improved design, long-travel switches, standard gasket mount structure, a massive battery life of up to 1,200 hours, and easy-to-use browser-based customization software, the Air75 V3 promises to be an “all-in-one” choice for those looking for a thin and light mechanical keyboard that doesn’t compromise on experience.

1. From design icon to NuPhy Air75 V3 comeback

NuPhy Air Series was once a symbol of thin and light design combined with top-notch typing quality. This product line created a wave of low-profile mechanical keyboards when it was the first to bring high-end configurations such as mechanical switches, quality keycaps, and diverse connectivity into an ultra-thin design.

However, in the last 1-2 years, the Air line has started to face fierce competition. Competitors like the Iqunix Magi65 Pro or Lofree Flow Lite have not only learned, but have gone one step ahead by integrating technologies like gasket mounts, lighter Kailh switches, and more modern custom software.

Unable to stay out of the fray, NuPhy has quietly prepared for its return with the Air75 V3 – a comprehensive upgrade in both technology and user experience.

2. Outstanding improvements from design to typing experience

2.1. Gateron LP 3.0

The Air75 V3 is the first product in the Air Series to use Gateron Low-Profile 3.0 switches, a switch with a travel distance of up to 3.5 mm, an impressive number for a thin and light mechanical keyboard.

Previously, the Air75 V2 used LP 2.0 switches, which were limited to a travel of only about 2.5 mm, making the typing experience not really "satisfying" for those who are used to using full-size mechanical keyboards. With LP 3.0, things are different. The typing experience on the Air75 V3 feels more solid, deep, and responsive, thanks to the longer key travel while still maintaining the thinness and lightness of the design.

2.2. Gasket mount

Another extremely important improvement is the gasket mount structure, something users have long been waiting for. Previously, NuPhy only equipped the tray-mount for the Air line, which was quite stiff and not elastic when typing.

With gasket mount, Air75 V3 creates a slight bounce when pressing the keys, providing a smooth, comfortable typing feel and a more "clear" sound. This helps reduce hand fatigue when typing for a long time and makes the typing process more enjoyable.

2.3. New frame design

NuPhy has reworked the Air75 V3's chassis. The CNC aluminum upper section gives it a sleek, sturdy look, while the ABS plastic lower section reduces overall weight. The inner plate is made of transparent PC, optimizing light transmission for RGB lighting and helping to soften typing sounds.

In addition, the base and tilt angle have also been redesigned to optimize the long-term typing experience, while maintaining the mobility factor - one of the highlights of the Air series.

3. Outstanding technical specifications

Despite aiming for thinness and lightness, the Air75 V3 still possesses technical specifications that make even the most meticulous people nod in agreement:

4. NuPhy IO 2.0 Software

Along with the powerful hardware upgrade, NuPhy Air75 V3 also has a notable highlight in software: NuPhy IO 2.0 - a keyboard configuration tool directly on the browser.

Unlike traditional software that requires downloading and installation, NuPhy IO 2.0 operates entirely on the web, making it easy for users to access anywhere, on any operating system from Windows, macOS to Linux or ChromeOS.

4.1. Friendly interface, easy to get used to

Right from opening the configuration page, users will see that the IO 2.0 interface is very intuitive, with clear keyboard illustrations that help identify each key, each layer and each function area easily.

This is especially useful for:

New to custom mechanical keyboards
Users without deep technical knowledge
Those who switch between multiple devices and don't want to install cumbersome software

4.2. What you can do with NuPhy IO 2.0

Key Remapping

You can change the function of each key, for example, turn Caps Lock into Ctrl, or swap the position between Esc and ~ if you are used to the classic layout. The actions are updated in real time, no need to flash from scratch each time.

Set up macros

The macro feature allows you to create a sequence of key actions (paragraph typing, shortcut commands…) with just one press. This is an extremely useful tool for:

Programmer (run sample code)
Designer (run Adobe key combination)
Gamer (assign combo command)
Customize the knob

With the Air75 V3, the dial isn't just for decoration – it can be customized:

Volume up/down
Zoom in/out
Scroll vertically/page
Transfer songs/media
Or assign any macro you want
This is done easily in IO 2.0, no coding, no firmware searching, just select the function from the drop-down menu.

4.4. Flash firmware directly

This is a rare feature in keyboards that do not use official VIA/QMK: you can upgrade the firmware directly in the browser, without installing a tool like QMK Toolbox.

This is especially convenient when:

NuPhy releases new patches (e.g. LED fix, improved polling speed)
You need to restore the original firmware after deep customization

4.5. Advantages and disadvantages of IO 2.0

Advantage

Disadvantages

Easy to use interface, no installation required

Customization is not as deep as QMK

Cross-platform (browser) operation

Does not support complex layers

Easy firmware flash support

Lacks "live testing" feature like VIA

Macro & rotation support

Not open-source

In conclusion, NuPhy IO 2.0 is not the most powerful software, but it is one of the most accessible and user-friendly platforms today, especially for ordinary users or those who value convenience and speed when customizing the keyboard.

5. Outstanding features

Not only stopping at the structure and software, NuPhy Air75 V3 also brings subtle but extremely practical details. Among them, the knob and smart battery indicator are two notable highlights.

5.1. Removable knob

In the upper right corner of the keyboard, you'll find a multi-function rotary dial, an increasingly popular feature on high-end keyboards thanks to its convenience and intuitive "mechanical" control feel.

However, NuPhy does something more interesting: you can remove this dial and replace it with a standard key switch that turns that area into a function key, macro, or shortcut of your choice.

Not only that, the knob also comes in two height versions:

Low-profile (short): ideal for people who travel frequently, helps buttons not get in the way when putting the keyboard in a backpack or laptop bag

Tall-profile: suitable for fixed setup at the desk, providing a more “hands-on” adjustment feel

This versatility makes the Air75 V3 transcend the form factor into a deeply personalized tool for both work and play.

5.2. Smart battery indicator

One of the downsides of previous Air models is the vague battery indicator light system that only flashes a few times and then turns off, making it difficult for users to know when to charge.

Air75 V3 completely overcomes this point with a smart battery indicator that clearly displays the percentage. You can easily check the remaining battery capacity right on the keyboard, without having to connect to software or wait for a low battery warning.

Combined with the super-large 4,000 mAh battery, this feature becomes extremely useful:

No more worries about the keyboard "suddenly dying" while working
Easily plan for charging when you're going on a business trip or taking your keyboard out
Especially useful for people working in environments without regular power outlets
After a period of being “overtaken” by emerging competitors, the NuPhy Air75 V3 is a timely and appropriate response. With significant improvements in switches, gasket structure, design, software, along with great battery life and customizable knobs. This is definitely the most anticipated thin and light mechanical keyboard of 2025. If you are looking for a compact, flexible mechanical keyboard, but not lacking in depth in the typing experience, the Air75 V3 is a name worth pre-ordering today.
