Keychron B40 Wireless Keyboard

The Keychron B40 is a 75% Alice-layout wireless keyboard built for office days. It pairs quiet scissor keys with tri-mode connectivity and long battery life to keep your desk simple.

  • Alice Ergonomic Layout: The curved layout keeps your hands in a natural position and frees up room for your mouse.
  • Quiet Scissor Keys: Keycaps sit 59% taller than standard scissor switches, so each press feels deep and stable without extra noise.
  • Tri-Mode Connectivity: Switch between 2.4 GHz, Bluetooth 5.2, and USB-C, and pair up to three Bluetooth devices at once.
  • 330-Hour Battery Life: The 800 mAh battery runs for weeks in 2.4 GHz mode, then recharges over USB-C.
  • M1-M5 Macro Keys and AI Launcher: Five macro keys handle shortcuts and text snippets, and the browser-based Launcher lets you remap keys with AI help.

The Keychron B40 fits any desk that needs comfortable typing, solid connectivity, and a battery that lasts for weeks.
