Nuphy Air75 V2 vs Keychron V5 MaxLow-Profile vs Full-Size Layout

The Nuphy Air75 V2 is specifically marketed as a laptop partner, with a vendor-provided list of compatible laptops including various MacBook models. Its low-profile design is meant to sit neatly over a laptop keyboard. The Keychron V5 Max also supports macOS and includes Mac-specific keycaps, but its large size makes it a desktop peripheral rather than a travel companion.

Yes, both keyboards are hot-swappable. The Keychron V5 Max listing explicitly states compatibility with 3-pin and 5-pin MX switches like Gateron, Cherry MX, and Kailh. The Nuphy Air75 V2 uses low-profile KS-33 sockets, which are incompatible with standard Cherry MX switches and require low-profile switches like Nuphy's own or Gateron's Low-profile series.

Yes. Both the Nuphy Air75 V2 and Keychron V5 Max offer tri-mode connectivity: 2.4GHz wireless, Bluetooth, and wired USB-C. Both achieve a 1000Hz polling rate in their 2.4GHz and wired modes for responsive gaming and typing.

The typing feel differs significantly due to construction. The Keychron V5 Max uses a gasket mount design with a polycarbonate plate and sound dampening foam, aiming for a softer, more cushioned feel.

Both have the same 4000mAh battery capacity. Vendor lab tests show similar ranges: the Air75 V2 claims up to 220 hours with lights off, while the V5 Max claims up to 190 hours. Actual battery life will vary based on usage, backlight brightness, and connection mode.
