Product Overview
75% Compact Design
The K84 features a 75% layout with 84 keys, removing the numeric keypad while retaining dedicated media keys and arrow keys. This makes it more practical than 60% keyboards while still saving significant desk space compared to full-size layouts. Perfect for small desks, gaming setups, or users who need portability without sacrificing essential keys.
Wireless Performance
Utilizing 2.4GHz wireless technology, the K84 delivers a stable, lag-free connection for both gaming and productivity. Both the keyboard and mouse share a single USB receiver (stored in the keyboard or mouse bottom compartment), eliminating clutter and conserving USB ports. The wireless range extends up to 10 meters, providing flexibility in your workspace setup.
Ultra-Lightweight Mouse
The included mouse features a honeycomb shell design that reduces weight to just 65 grams (±5g) while maintaining structural integrity. The perforated design enhances airflow, keeping your palm cool during extended gaming sessions. The ergonomic shape with anti-sweat texturing provides comfortable grip and precise control.
Rainbow LED Backlighting
The K84 keyboard includes rainbow LED backlighting with customizable modes to suit your preference. Note that this is rainbow LED (not RGB), meaning colors cycle through a preset rainbow pattern rather than individual color customization.
Lighting Modes
- 3 static rainbow modes
- 1 dynamic breathing mode
- 3 brightness levels for day or night use
- 4 breathing speed adjustments
- 7-color cyclic gradient effect on mouse
Battery-Saving Options
Disable the backlight completely to significantly extend battery life. The keyboard and mouse feature smart energy-saving functions, automatically entering sleep mode after 2 minutes of inactivity. Press any key or button to instantly wake the devices.
Battery Life & Power Management
The K84 combo is equipped with rechargeable lithium batteries: 1850mAh for the keyboard and 500mAh for the mouse. With backlighting enabled, expect approximately 8 hours of continuous use. Turn off the lighting for extended battery life lasting several weeks depending on usage patterns.
