Manufacturer description

The 84-key tenkeyless layout keeps dedicated media keys and a real arrow cluster, so you skip the FN-gymnastics that make 60% boards frustrating for spreadsheets and everyday typing. Both halves run on 2.4G wireless through a single shared USB receiver, pre-paired out of the box, which means one dongle and one free USB port instead of two. Battery is the practical story here: a 1850 mAh cell in the keyboard and 500 mAh in the mouse, rated around 8 hours with lighting on, plus a 2-minute auto-sleep that wakes on any keypress.

RedThunder's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

How long does the RedThunder K84 battery last?

RedThunder rates about 8 hours of continuous use with the lighting on, from a 1850 mAh keyboard battery and a 500 mAh mouse battery. A 2-minute idle auto-sleep extends that between charges; pressing any key wakes them.

Do the keyboard and mouse need two USB receivers?

No. Both share a single 2.4G USB receiver, stored at the bottom of the keyboard or mouse. It ships pre-paired, so you plug in the dongle, switch both on, and type.

Is the K84 a full tenkeyless keyboard with arrow keys?

Yes. It is an 84-key 75% layout that keeps dedicated arrow keys and media keys, which is the main practical advantage over a 60% board that buries both behind FN combos.

How much does the K84 mouse weigh and what DPI does it run?

The honeycomb-shell optical mouse weighs 65 grams plus or minus 5, and tops out at 3200 DPI. The perforated shell and light weight are aimed at long sessions without wrist fatigue.

Can I control the mouse RGB lighting?

No. The mouse light cycles through 7 colors automatically with no manual adjustment, and the scroll wheel light only illuminates while charging. The keyboard is the configurable half, with 4 dynamic modes, 7 solid colors, and rainbow RGB.
