What is the difference between the 1K, 4K, and 8K versions?

They differ in maximum polling rate: 1,000 Hz, 4,000 Hz, or 8,000 Hz over 2.4 GHz. Higher polling sends position updates more often, which suits competitive gaming but uses more battery.

Does it work with Mac and Windows?

Yes. It connects over 2.4 GHz with the receiver, over Bluetooth, or by USB-C cable, so it works with Windows, macOS, and other Bluetooth hosts. Settings are changed in the Keychron Launcher web app.

How long does the battery last?

Keychron rates it at up to 140 hours. Expect less at 4K or 8K polling, and more at 1K or in Bluetooth mode.

Can I use it for office work as well as gaming?

Yes. Bluetooth lets you pair it with a laptop or tablet, and the Launcher app handles button remapping and macros for work shortcuts.

Is the 8K polling rate worth it over 1K?

Only if you play fast competitive games and have a display and USB setup that can use the extra updates. For everyday use and most work, 1K is enough and saves battery.
