FAQ

Nuphy Air75 V2 vs Epomaker TH40: your questions

The Nuphy Air75 V2 is far better for layer-free typing. Its 75% layout includes a dedicated number row, arrow keys, and a navigation cluster. The Epomaker TH40, as a 40% keyboard, requires using the function layer to access numbers, symbols, and arrows.

You can, but with significant compromises. The TH40 supports a 1000Hz polling rate, but its 40% layout means vital gaming keys like arrows and function keys are only accessible through layers, which can be cumbersome during fast-paced gameplay.

Yes. Both the Nuphy Air75 V2 and Epomaker TH40 list compatibility with Windows and Mac operating systems. The Air75 V2's vendor description also specifically mentions Linux and includes Mac-specific shortcut keycaps.

The Nuphy Air75 V2 has a larger 4000mAh battery compared to the Epomaker TH40's 3000mAh battery. While actual runtime depends on usage and RGB settings, the Air75 V2 has a higher capacity for longer wireless operation.

Yes, both use standard keycap mounts. However, the Nuphy Air75 V2 uses low-profile keycaps, which are not interchangeable with the standard Cherry profile keycaps on the Epomaker TH40. You must buy keycaps specifically designed for each keyboard's profile.

A gasket mount uses rubber or silicone gaskets to suspend the plate and PCB inside the case, aiming to reduce vibration and create a softer typing feel. The Epomaker TH40 uses a gasket mount design. The Nuphy Air75 V2 does not specify a gasket mount in its provided details.

Yes. Both the Nuphy Air75 V2 and Epomaker TH40 feature hot-swappable sockets, allowing you to change mechanical switches without soldering. The Air75 V2 is compatible with low-profile Gateron KS-33 switches, while the TH40 uses standard 3-pin or 5-pin switches.

The Nuphy Air75 V2 is significantly more beginner-friendly. Its layout is familiar and requires no special training to use. The Epomaker TH40's 40% layout has a steep learning curve, as you must memorize complex key layers for basic functions.

Both keyboards are programmable using the open-source VIA software, which allows for key remapping and macro creation. The Nuphy Air75 V2 also supports QMK firmware. User reviews for both models note that getting VIA to recognize the keyboard can sometimes require troubleshooting.

The Nuphy Air75 V2 includes a USB-C cable, a 2.4G receiver, extra keycaps and switches, a puller tool, and a sticker set. The Epomaker TH40's listed contents are more basic, including just the keyboard, a USB cable, and a user manual.

The Nuphy vendor description lists extensive laptop compatibility, stating it has been tested with models from Apple, Microsoft, Lenovo, HP, Dell, and Razer. Its low-profile design is specifically marketed as a laptop partner.
