Keychron K4 Ultra 8K Wireless Mechanical Keyboard, Keychron Apex Brown, Black

The Keychron K4 Ultra 8K is a work-and-gaming keyboard with tactile Keychron Apex Brown mechanical switches. Its 96% layout retains a dedicated number pad while using less desk space than a full-size keyboard. Connection options include 2.4 GHz wireless, Bluetooth 5.2, and wired USB-C. The 8000 Hz polling rate is supported in wired and 2.4 GHz modes, giving faster input reporting for gaming. Its Nordic ISO layout is intended for users who need that regional key arrangement.

The frame combines ABS, steel, and PBT, while double-shot PBT keycaps use an OSA profile. Adjustable per-key RGB lighting allows individual key illumination settings. N-key rollover and anti-ghosting support simultaneous key presses during fast input. Programmable hotkeys and multimedia keys provide additional controls, and the keyboard is compatible with macOS, Windows, and Linux. A rechargeable 4000 mAh battery is rated for up to 600 hours, depending on use and lighting settings, and charges via USB-C.
