Tri-Mode Wireless Keyboard for Gamers

The Redragon K521KS connects via Bluetooth, 2.4 GHz wireless or USB-C wired modes. It pairs with up to five devices and switches between them within a 10 metre range. A built-in 4000 mAh lithium-ion battery removes the need for disposable cells. Twenty-five anti-ghosting keys register simultaneous presses accurately during play.

Battery Life and Quiet Operation

The 4000 mAh rechargeable battery powers extended sessions without frequent top-ups. USB-C wired use charges the pack while you work or game. Mechanical-feeling tactile switches deliver responsive feedback without the loud click of traditional clicky mechanisms. Plastic construction keeps the deck light and cool during normal use.

Compact Build for Flexible Setups

Tri-mode connectivity lets the keyboard serve a desktop, laptop and tablet without extra dongles. Wireless freedom clears desk space for mouse movement. Programmable software customises RGB lighting, key assignments and macros to match personal workflow. The board suits players who want cable-free flexibility and users who switch between multiple machines daily.

Questions about this item

How do I switch between Bluetooth, 2.4 GHz wireless and USB-C wired modes on the Redragon K521KS?

Use the mode selector on the keyboard to cycle through Bluetooth, 2.4 GHz wireless and USB-C wired connections; pair up to five devices and switch between them within a 10 metre range.

What part of the Redragon K521KS will need replacement first and how is it serviced?

The built-in 4000 mAh lithium-ion rechargeable battery is the only user-serviceable component; when it no longer holds a charge the entire keyboard must be replaced because the battery is not user-replaceable.

How many simultaneous key presses does the 25-key anti-ghosting on the Redragon K521KS actually guarantee?

The anti-ghosting implementation ensures every one of the 25 designated keys registers correctly even when pressed together, so complex combinations in games are recognised without conflict.
