Keychron J10 Ultra 8K Full Aluminum Wireless Custom Mechanical Keyboard

Features

• 75% Layout Performance Keyboard: The Keychron J10 Ultra 8K features a compact 75% layout that keeps the function row and arrow keys while saving desk space, ideal for users who want a clean, high-performance desktop. The aluminum CNC machined knob offers quick, precise control of volume and backlight, and the hot-swappable design makes it easy to build your own typing experience. Fully supports macOS, Windows and Linux for flexible cross-platform productivity.
• Ultra-Fast 8000 Hz Performance: Built for speed, the J10 Ultra 8K delivers an 8000 Hz polling rate in both 2.4 GHz wireless and wired modes with an ultra-low 0.125 ms latency, for ultra-responsive input in work, creation, and light gaming. The polling rate is adjustable via the Keychron Launcher web app; by default, it is set to 1000 Hz in 2.4 GHz and wired modes.
• Tri-Mode Connection & 645-Hours Battery: Connect the J10 via low-latency 2.4 GHz wireless, Bluetooth 5.3, or USB-C wired mode. Pair with up to 3 devices via Bluetooth and switch easily between your computer, phone, and tablet. The built-in 4000 mAh battery provides up to 645 hours of continuous use with backlight off at an 8000 Hz polling rate, freeing you from frequent charging.
• Open-Source ZMK & Keychron Launcher: Powered by open-source ZMK firmware, the J10 is designed for you to explore, customize, and develop the features you want. Remap every key, create macros, and choose from 22 subtle RGB backlight effects via the Keychron Launcher Web App - no software download required. Please use the latest version of Chrome, Opera, or Edge browser to open the Launcher.
• Hot-Swappable & Refined Typing Feel: Swap any 3-pin and 5-pin MX switches in seconds without soldering. Pre-lubed APXE switches, Cherry-profile double-shot PBT keycaps, premium full aluminum body, and multi-layer sound-dampening foams (ASL, IXPE, PET, EPDM) work together for a deeper, quieter, and more satisfying keystroke. Truly silent switch options are available for shared spaces and late-night sessions.
