The Keychron K2 Max updates the familiar 75% K2 formula with tri-mode connectivity and QMK customization. Its 84-key ANSI layout keeps function and arrow keys in a compact frame, while 2.4 GHz, Bluetooth for up to three devices, and wired USB-C cover work across macOS, Windows, and Linux. Keychron lists hot-swappable versions with its Super Red, Brown, or Banana switches, double-shot PBT keycaps, and a 4,000 mAh battery rated for up to 190 hours. Included Mac and Windows keycaps and the Keychron Launcher web app round out a desk-friendly, configurable package.
