Compare Keychron K1 Pro vs K2 Pro Differences Side by Side

This comparison is for buyers deciding between a slim low-profile keyboard and a feature-packed traditional 75% layout. The decision is difficult because both keyboards share the same brand, QMK/VIA support, and Bluetooth 5.1 connectivity, but their ergonomics and physical designs are very different. The K1 Pro is an ultra-slim 80% board with a 3 degree typing angle and a lightweight 580g aluminum and plastic frame. The K2 Pro is a heavier 1070g 75% board with a steel plate, sound dampening foam, a 5 degree typing angle, and a 4000mAh battery that more than doubles the K1 Pro's capacity.
