REDTHUNDER K20 TKL WIRELESS
KEYBOARD & MOUSE COMBO

The RedThunder K20 TKL wireless gaming keyboard and mouse combo combines space-saving tenkeyless design with full RGB customization and dedicated multimedia controls. Featuring an 85% compact layout, adjustable RGB backlighting, and a lightweight 85g mouse, the K20 delivers premium wireless performance for gaming and productivity.

Key Features

Product Overview

TKL Design Philosophy

The K20 adopts a tenkeyless (TKL) layout that balances functionality with compact size. By removing the numeric keypad, the keyboard reduces its footprint by approximately 30% compared to full-size models. This creates valuable desk space for wider mouse movements – essential for low-sensitivity gaming and detailed creative work.

Multimedia Integration

Unlike many TKL keyboards that require function key combinations for media control, the K20 features 6 dedicated multimedia keys. These provide instant access to volume adjustment, playback controls, and other media functions without interrupting your workflow or gameplay. The intuitive placement ensures these controls are always within easy reach.

Wireless Performance

Utilizing 2.4GHz wireless technology, both the keyboard and mouse share a single USB receiver (located in the mouse bottom compartment). The stable connection minimizes input lag, making it suitable for competitive gaming and productivity tasks. Smart energy-saving functions automatically put devices to sleep after 1-3 minutes of inactivity, extending battery life significantly.

RGB Lighting System

The K20 features comprehensive RGB backlighting with extensive customization options. Unlike rainbow LED systems, true RGB allows for individual color selection and advanced lighting effects.

Keyboard RGB Modes

• 4 dynamic backlight effects with customizable speed
• 7 RGB monochrome lighting modes (single color selection)
• 1 RGB rainbow effect (full spectrum cycle)
• 4 brightness levels for ambient lighting control
• 4 breathing speed adjustments for dynamic effects

Mouse Lighting

The mouse includes 10 adjustable RGB backlight effects that can be controlled independently. An LED button on the mouse allows quick cycling through lighting modes to match your setup or preference.

Battery & Charging

Both the keyboard and mouse feature rechargeable batteries designed for extended wireless use. With RGB lighting enabled, expect approximately 8 hours of continuous operation. Disable lighting for significantly extended battery life lasting days or weeks depending on usage intensity.

Type-C Charging

• Type-C USB charging port on both devices
• Same charging cable works for both keyboard and mouse
• Mouse wheel illuminates during charging to indicate status
• Mouse automatically switches to wired mode when charging
• Can be used while charging for uninterrupted operation

Smart Power Management

Automatic sleep mode activates after 1-3 minutes of inactivity (configurable). Press any key or move the mouse to instantly wake the devices. When battery runs low, key response may slow or lights may flash – charge promptly to maintain optimal performance.
