GMMK Numpad vs Keychron Q0 Max

The Keychron Q0 Max offers more wireless options, including a 2.4 GHz dongle connection with a specified 1000 Hz polling rate and Bluetooth 5.1. The GMMK Numpad offers Bluetooth 5.0 LE and wired connectivity. For low-latency wireless use, the Q0 Max's 2.4 GHz mode is advantageous.

Yes, both the GMMK Numpad and Keychron Q0 Max feature hot-swappable PCBs. The GMMK Numpad's listing states it supports both 3-pin and 5-pin switches. The Keychron Q0 Max is also hot-swappable and compatible with standard MX-style switches.

The Keychron Q0 Max is significantly more customizable, featuring native support for the open-source QMK and VIA firmware. This allows for deep key remapping, macro creation, and layer programming. The GMMK Numpad uses Glorious Core software and, according to its vendor page, also supports QMK.

Yes, both the GMMK Numpad and Keychron Q0 Max are listed as compatible with macOS and Windows operating systems. The Keychron listing also specifically mentions Linux compatibility.

The GMMK Numpad comes with OEM profile double-shot ABS keycaps. The Keychron Q0 Max (fully assembled version) includes KSA profile double-shot PBT keycaps, which are generally more resistant to oil and shine over time compared to ABS.

A gasket mount uses rubber or silicone gaskets to suspend the plate and PCB within the case, aiming to reduce vibration and create a softer, more consistent typing feel. The Keychron Q0 Max features a double-gasket design. The GMMK Numpad vendor description mentions a gasket mount design, but its metadata specifies a plate mount.

The Keychron Q0 Max is likely quieter by design. It includes multiple layers of sound-dampening foam (IXPE, PET, Latex) and a double-gasket design specifically aimed at reducing acoustic resonance and typing noise. The switch choice will also greatly impact sound.

Yes. The Keychron Q0 Max is offered in a Barebone Knob version, which includes the aluminum case, PCB, plate, stabilizers, and foams, but does not include switches or keycaps. This is ideal for users who want to install their own preferred components immediately.

According to its specifications, the Keychron Q0 Max has a 1800mAh rechargeable battery. Keychron states it provides up to 50 hours of wireless working time with RGB lighting at its lowest brightness.

The GMMK Numpad has north-facing RGB LEDs. The Keychron Q0 Max has south-facing RGB LEDs. South-facing LEDs avoid interference with Cherry-profile keycaps but may provide less direct backlighting with its included non-shine-through PBT caps.

Both numpads use screw-in stabilizers. The GMMK Numpad specifies GSV2 screw-in stabilizers, while the Keychron Q0 Max uses PCB-mounted screw-in stabilizers, which are generally preferred for their stability and ease of modification.

The Keychron Q0 Max is notably heavier, with a listed weight of 684 grams for the fully assembled version. The weight of the GMMK Numpad is not specified in the provided information, but its construction with a plastic bottom suggests it is likely lighter.
