Compare Keychron K3 V2 vs Q3 Differences Side by Side

This comparison is for buyers deciding between a travel-friendly wireless keyboard and a premium wired workhorse. The K3 V2 is an ultra-slim low-profile board with Bluetooth and a 1550mAh battery, while the Q3 is a heavy full aluminum TKL with QMK/VIA support and a gasket mount. The decision is hard because both are hot-swappable from Keychron but target completely different priorities: mobility versus typing feel and modding potential.
