75% Tri-mode wireless mechanical keyboard

The Redragon K757-00 is a compact 75% layout keyboard with Bluetooth 5.0, 2.4GHz wireless and USB-C wired connectivity. It supports simultaneous pairing with up to five devices and switches between them via shortcut keys. Pre-lubed linear switches, gasket structure and PBT keycaps deliver a creamy sound and smooth typing feel.

Verify USB-C port and hot-swap switch preference

Ensure your system has an available USB port for the wired or 2.4GHz dongle connection. The hot-swappable PCB accepts both 3-pin and 5-pin switches so you can change them without soldering. A 4000mAh rechargeable battery powers the board for extended wireless use.

Replaces full-size wired boards for multi-device

This keyboard upgrades from a standard wired model by adding tri-mode wireless freedom and a multi-function knob for volume or media control. The jump is worth it if you need a smaller footprint, per-key RGB with 15 lighting modes and the ability to customise switches and macros via software.

Questions about this item

Does the box include everything needed to start using the Redragon K757-00 or must I buy a cable or switches separately?

The keyboard ships with a USB cable for wired use and charging, pre-lubed linear switches already installed, and PBT keycaps fitted, so no extra purchase is required to begin typing or gaming.

Should I choose the 75% layout with knob or a different version for maximum desk space and media control?

This single 75% model includes a multi-function knob and 75 keys, giving a compact footprint while keeping dedicated media control and arrow keys in one unit.

What does the 4000mAh battery actually deliver during daily wireless use with RGB active?

The 4000mAh cell provides long-lasting wireless operation; visible battery level indicators let you monitor charge, and the tri-mode design allows instant wired fallback when the battery runs low.
