Manufacturer description

The RedThunder K84 answers a narrow question well: can one rechargeable 2.4G kit cover both spreadsheet work and evening matches without swallowing your desk? The 84-key 75% layout keeps dedicated arrow and media keys that 60% boards drop, so you keep Home, End and volume control while reclaiming the numpad's footprint. Keyboard and mouse pair to a single USB receiver stored in the chassis, and the code is set at the factory - plug it in, flip both power switches, and you are typing. Power comes from a 1850 mAh keyboard battery and a 500 mAh mouse battery, rated for roughly 8 hours of use…

SpecPicks Verdict

SpecPicks scored RedThunder K84 Wireless Keyboard and Mouse Combo using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. RedThunder's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for gaming peripherals of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

How long does the RedThunder K84 battery last on a charge?

RedThunder rates both devices for about 8 hours of continuous use with the lighting on. The keyboard holds a 1850 mAh cell and the mouse a 500 mAh cell, and both sleep after 2 minutes of inactivity to conserve charge. Turning backlighting off extends runtime.

Do the keyboard and mouse use separate USB receivers?

No. Both share a single 2.4G USB receiver, stored in a bay on the underside of the keyboard or mouse. They ship already paired, so you plug in the one dongle, switch both on, and they work. If they drop the connection, you can redo the code pairing.

Does the K84 have a number pad?

No. It is an 84-key 75% tenkeyless layout, so the numpad is gone to save desk space. RedThunder kept the dedicated arrow cluster and media keys, which most 60% boards drop, so you still get directional and volume control without a function-layer combo.

Can I control the mouse RGB lighting?

Not manually. The mouse light cycles through 7 colors automatically with no adjustment option, and the scroll wheel light illuminates only while the mouse is charging. The keyboard is the adjustable half: 4 dynamic backlight modes, 7 solid colors and RGB rainbow.

Is the RedThunder K84 good for gaming as well as office work?

That is the pitch. The 3200 DPI optical sensor and 65-gram honeycomb mouse suit fast aiming, while the 2.4G link and 10-million-keystroke switch rating cover daily typing. Expect budget-tier rather than enthusiast performance.
