Redragon RK400-US Gaming Keyboard 104 Keys RGB Wired with Mouse

Full-size 104-key USB gaming combo

The Redragon RK400-US bundles a standard-layout keyboard and an adjustable-DPI mouse into one wired USB package. Both peripherals connect through a single port each and require no driver installation on supported systems. The keyboard includes a detachable wrist rest and a braided cable for desk durability. It targets entry-level PC and Mac users who want a complete RGB set without extra software.

RGB lighting and DPI switching on hardware

The keyboard offers three lighting modes, seven colour effects, multiple brightness levels and adjustable animation speeds controlled by FN key combinations. Twenty-six anti-ghosting keys and twelve multimedia shortcuts work without software. The mouse provides four hardware DPI steps at 1200, 1600, 2400 and 3200, changed via a dedicated button. LED breathing effects on the mouse cycle automatically.

Single USB port per device requirement

Each peripheral needs its own USB Type-A port, so the combo occupies two ports on the host. The keyboard draws up to 400 mA at 4.5–5.5 V, while the mouse runs from an internal rechargeable lithium-ion cell. Builders with only one free USB port or laptops lacking Type-A sockets cannot use both devices simultaneously without a hub.
