Nuphy Air75 V2 vs Keychron Q1 MaxLow-Profile vs Premium Build

The Nuphy Air75 V2 is specifically marketed as a laptop partner. Its vendor page lists compatibility with MacBook models from 2015-2023 and includes dedicated keycaps and QMK-based shortcuts for MacOS functions like Spotlight and Dictation. Its low-profile design also fits over the laptop's own keyboard.

Yes, both keyboards are hot-swappable. The Keychron Q1 Max vendor description explicitly states compatibility with Cherry, Gateron, Kailh, and other MX-style switches. The Nuphy Air75 V2 uses low-profile Gateron KS-33 sockets, which are only compatible with low-profile switches, not standard Cherry MX switches.

Both have a 4000mAh battery. The Nuphy Air75 V2 vendor claims up to 220 hours with lights off. The Keychron Q1 Max vendor claims up to 180 hours with backlight off. Real-world results will vary with usage, but both offer strong battery performance for a wireless mechanical keyboard.

The Keychron Q1 Max weighs 1724g (over 3.7 lbs), which is very substantial. This weight contributes to its premium, stable feel on a desk but makes it impractical for regular travel. The Nuphy Air75 V2, at 598g, is less than a third of the weight and is designed for portability.

Yes. Both the Nuphy Air75 V2 and Keychron Q1 Max support QMK and VIA firmware for extensive key remapping, macro creation, and lighting customization. The Keychron also offers its own Launcher web app for configuration.

The typing feel is fundamentally different. The Air75 V2 uses low-profile switches with 3.0-3.2mm total travel for a short, snappy feel. The Q1 Max uses standard-profile switches in a gasket-mounted, foam-filled aluminum case, aimed at providing a deeper, more cushioned, and acoustically dampened typing experience.

Based on construction, the Keychron Q1 Max likely has a deeper, more muted sound profile due to its multiple acoustic foam layers (IXPE, PET, Latex), gasket mount, and polycarbonate plate. The Nuphy Air75 V2 also includes plate poron and IXPE foam but in a thinner, more open low-profile case, which may result in a higher-pitched sound.

Yes. The Keychron Q1 Max is offered in a Barebone Knob version, which includes the aluminum case, PCB, plate, and stabilizers, but does not include keycaps or switches, allowing for complete personalization from the start.

No. The Nuphy Air75 V2 does not have a knob. The Keychron Q1 Max includes a knob, which can be used for volume control, scrolling, or assigned to other functions via QMK/VIA.

Yes, both keyboards come with PBT keycaps. The Nuphy Air75 V2 uses its nSA profile double-shot PBT keycaps. The Keychron Q1 Max offers a choice between KSA double-shot PBT or OSA side-printed double-shot PBT keycaps.

The Nuphy Air75 V2 vendor lists 40 backlight modes and includes side light bars. The Keychron Q1 Max vendor lists 22 RGB backlight settings with a static white option and features south-facing LEDs for better compatibility with sculpted keycaps.
