Compact 75% Layout

The RedThunder K75 is an 80-key wireless keyboard and mouse combo built for gaming and everyday use. Its 75% form factor saves 25% desktop space compared with a full-size board, and side-engraved keycaps resist wear while staying legible in low light. A CNC metal knob handles volume, mute and RGB brightness through simple press-and-rotate actions. The membrane switches deliver quiet, comfortable keystrokes suitable for long sessions.

Three Connection Modes

Connect via Bluetooth, 2.4 GHz wireless using the shared USB receiver stored in the keyboard or mouse, or wired USB-C when you need to charge and type simultaneously. One-key switching toggles between Windows and macOS layouts with a coloured backlight flash for confirmation. The mouse pairs through the same receiver or Bluetooth using a dedicated button combination. Note that the set is not compatible with PlayStation consoles.

Optical Mouse Precision

The included gaming mouse uses an optical sensor rated at 4800 DPI, providing adjustable sensitivity for fast-paced play or precise work. Both peripherals run on rechargeable batteries, eliminating disposable cells. The combo suits users who want a tidy, portable desktop kit with flexible connectivity, while buyers needing mechanical switches, dedicated macro keys or console support should look elsewhere.

Questions about this item

How long does the rechargeable battery last before I need to plug in the USB-C cable?

The keyboard and mouse run on built-in rechargeable batteries; use the original USB-C cable to charge and continue typing in wired mode.

How loud are the membrane keys and does the combo get warm during all-day sessions?

Membrane switches keep keystrokes quiet and comfortable, and the low-power wireless design produces minimal heat during extended use.

What do I need on my computer to use the 2.4 GHz wireless link?

A free USB-A port for the single shared receiver stored under the keyboard or mouse; the combo works with Windows and macOS via Fn+A/S switching.
