Product information

Description

The Keychron K3 Max is a low-profile 75% mechanical keyboard with 84 keys, designed for home and office use. It combines a compact straight-form aluminium body with low-profile Gateron mechanical switches, offering tactile typing and a reduced desk footprint. The keyboard supports triple connectivity — wired USB, 2.4 GHz RF wireless with a 1000 Hz polling rate, and Bluetooth 5.1 — and includes full RGB backlighting with multiple effects. QMK firmware support and Keychron Launcher compatibility enable flexible key remapping, macros and multiple keymaps for macOS and Windows.

Advantages

The K3 Max delivers a slim mechanical typing experience through Gateron low-profile switches and double-shot PBT keycaps that resist oil and wear. Its aluminium build and interior IXPE and latex acoustic foams reduce noise while improving key response and durability. Triple connectivity and a 1000 Hz polling rate on 2.4 GHz provide low-latency performance for demanding tasks. QMK programmability and the Keychron Launcher web app allow users to customize layouts and shortcuts without advanced technical steps. Adjustable typing angles and redesigned stabilizers improve ergonomics and large-key stability.

Suitable for

  • Typing and office productivity on desktop and laptop
  • Multitasking across computer, tablet and phone via Bluetooth and 2.4 GHz
  • Competitive and casual gaming requiring low-latency wireless or wired input
  • Developers and power users who remap keys or create macros with QMK

Key specifications

  • Layout: 75% compact form with 84 keys
  • Switches: Low-profile Gateron mechanical switches (available linear, tactile, or clicky types)
  • Keycaps: Low-profile double-shot PBT keycaps
  • Connectivity: USB wired, 2.4 GHz RF wireless (1000 Hz polling), Bluetooth 5.1 (multi-device)
  • Backlight: RGB backlighting with multiple effects (and a white-backlight variant)
  • Body: Slim aluminium chassis
  • Firmware: QMK-compatible with Keychron Launcher web app support
  • Acoustic treatment: IXPE acoustic foam and latex support foam inside
  • Adjustability: Three typing angle positions

How to use

Connect the keyboard to a device using the provided USB cable for wired mode, pair via the 2.4 GHz USB dongle for low-latency wireless, or enable Bluetooth and pair up to three devices. Use the Keychron Launcher web app to load or create custom keymaps, macros and profiles; QMK support allows deeper remapping and firmware-level customization for advanced users. Switch between Mac and Windows keycaps and keymaps as needed; the keyboard ships with both macOS and Windows keycaps and alternative Esc/Enter keys for straightforward OS switching.

Usage recommendations

For lowest latency in gaming, use the 2.4 GHz connection or wired USB mode. To extend battery life in everyday use, use Bluetooth for multi-device convenience and reduce RGB brightness or choose the white-backlight variant. If you prefer a different typing feel, choose the hot-swappable version to replace low-profile Gateron switches without soldering; ensure replacement switches are compatible low-profile mechanical switches.
