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.

Questions about this item
How long will the keyboard switches last before they need replacing?
The keys are rated for 5 million clicks, so heavy daily use will reach that limit after several years.
What limits performance first during long gaming sessions?
The keyboard draws 400 mA at 4.5–5.5 V, so the USB port’s current ceiling is the practical bottleneck.
How much heat or noise does the combo produce when left on all day?
The keyboard runs on 400 mA from USB with no fan, and the mouse uses a rechargeable lithium-ion cell, so both stay silent and barely warm.
