Full-Size Rainbow Backlit Combo

The BFKK gaming keyboard and mouse set delivers a full-size layout with black keycaps, rainbow backlighting at three brightness levels, and light-up letters for low-light use. The mouse offers fifteen switchable lighting effects. Both peripherals are rechargeable via the supplied USB-C cable and include an auto-sleep function that activates the keyboard after thirty minutes and the mouse after ninety seconds of inactivity.

Plug-and-Play 2.4 GHz Wireless

A single USB receiver connects both devices up to ten metres or thirty-three feet without requiring any driver installation. Dedicated on/off switches provide additional power control. The combo includes a USB-A to Type-C adapter for broader port compatibility, and a single touch toggles the keyboard between Mac and Windows layouts.

Check OS Multimedia Key Support

The hardware works with Windows, Linux, Chrome OS, and Mac, but the manufacturer notes that multimedia keys may not be fully compatible with Mac OS systems. Verify whether your workflow depends on those keys before ordering. Ensure a free USB-A port is available for the unified receiver.

Questions about this item

How can I confirm the keyboard and mouse are paired and functioning after plugging in the USB receiver?

The devices connect via the single 2.4GHz USB receiver up to 10 meters (33 ft). If the rainbow backlight illuminates on the keyboard and the mouse cycles through its 15 lighting effects, the link is active.

What comes in the box and is any extra cable or adapter needed for charging or Mac use?

The package includes the full-size keyboard, mouse, one USB receiver and a USB-C charging cable. A USB-A to Type-C adapter is also supplied for systems that only have USB-A ports.

Which version should I choose if I need both Windows and Mac layout switching with backlit keys?

This single model provides dual-system layout switching with a single touch and features light-up keycaps with 3 brightness levels, so no separate version selection is required.
