Compare Keychron K15 Max vs Q0 Max Differences Side by Side

This comparison is for users deciding between a unique low-profile ergonomic keyboard and a high-end standalone numpad. The choice is difficult because both are wireless, support QMK/VIA, and share Keychron's premium build, but they serve fundamentally different purposes. The K15 Max is a complete 75% Alice layout keyboard, while the Q0 Max is a dedicated number pad with a macro column and knob. Your decision hinges entirely on whether you need a primary input device or a specialized accessory.
