Features

Ultra-Slim Full-Sized Design

The K5 Max combines a complete 100% layout with an ultra-slim profile, providing dedicated function keys, navigation controls and a numeric keypad without sacrificing desk-friendly proportions. Its ABS and aluminium frame provides additional rigidity while keeping the keyboard lightweight.

Gateron Low Profile Red Switches

Pre-lubed Gateron Low Profile Red switches provide a smooth linear keypress with low sound levels, making them suitable for office work and gaming. The switches feature approximately 50 ± 15gf operating force, 1.7 ± 0.4mm pre-travel and 3.0 ± 0.2mm total travel.

Triple-Mode Connectivity

Connect using low-latency 2.4GHz wireless, Bluetooth 5.1 or a USB Type-C wired connection. The 2.4GHz and wired modes provide a fast 1000Hz polling rate, while Bluetooth supports convenient wireless use across compatible devices.

QMK/VIA Customisation

QMK firmware and Keychron Launcher compatibility allow individual keys to be remapped, macros to be created and shortcuts to be customised for different workflows. Separate macOS and Windows keymaps provide additional flexibility across operating systems.

Hot-Swappable Low-Profile Switches

The hot-swappable PCB allows compatible Gateron or Keychron low-profile mechanical switches to be replaced without soldering, making it easy to customise the typing feel or replace individual switches when required.

RGB Backlighting & Acoustic Foam

Choose from 22 RGB lighting effects and adjust brightness, hue and effect speed to suit your setup. Internal acoustic foam helps reduce unwanted typing noise, while redesigned stabilisers improve consistency on larger keys such as Spacebar, Shift and Enter.

Long-Lasting Wireless Battery

The built-in 2000mAh rechargeable battery provides approximately 90 hours of wireless operation with the backlight switched off and around 50 hours with RGB lighting at its lowest brightness under laboratory test conditions.

• Battery life varies according to connection mode, RGB brightness and usage.
• Hot-swap compatibility is limited to supported Gateron and Keychron low-profile mechanical switches.
• Keychron Launcher requires a supported browser and wired connection for configuration.
