About the Keychron K3 Max

The K3 Max is a thin mechanical keyboard for people who type all day. Low-profile Gateron switches keep it at 17 mm at the front (22 mm at the back, keycaps included), so most people can skip a wrist rest, and the 75% layout keeps the arrows and a function row in a 306 mm wide body with an aluminium frame.

It connects over 2.4 GHz (1,000 Hz), Bluetooth 5.1 or a USB-C cable, works with macOS, Windows and Linux, and every key can be remapped in Keychron's web Launcher (QMK/VIA). The 1,550 mAh battery lasts around 73 hours with the backlight off and about 42 hours with RGB at its lowest level. This RGB version has hot-swappable sockets, but they only take low-profile Gateron or Keychron mechanical switches. The price shown is for the black RGB model with Gateron Red linear switches.
