An $80 mechanical keyboard that travels well—and types better

TL;DR: The Keychron K3 is an ultra-slim, wireless, customizable mechanical keyboard that delivers a premium typing feel for just $79.99 (MSRP $104.99) with free shipping.

If you love mechanical keyboards but hate bulky boards that feel like workout equipment, the Keychron K3 Version 3 hits just right. It’s ultra-slim, wireless, customizable, and surprisingly powerful—especially at $79.99 with free shipping.

The K3 features a compact 75% layout, which keeps all the keys you actually use while saving valuable desk space. It connects via Bluetooth 5.2 (up to three devices) or USB-C, making it perfect for bouncing between a laptop, tablet, and desktop without missing a beat.

Typing is where this keyboard really shines. The new Keychron Milk POM low-profile switches are pre-lubed, smooth, and satisfyingly quiet, delivering a premium feel in a design that’s 33% slimmer than traditional mechanical keyboards. Add in hot-swappable support, and you can fine-tune your typing experience without soldering or stress.

Customization fans will appreciate QMK firmware and the Keychron Launcher web app, which lets you remap keys, create macros, and tailor shortcuts across macOS, Windows, and Linux. The RGB backlighting offers 22+ effects, while redesigned stabilizers and interior acoustic foam keep keystrokes solid and controlled.
