Our Verdict

Keychron C2

Keychron K12

The Keychron C2 is a wired full-size board, while the Keychron K12 is a wireless 60% compact board. Both units we tested have tactile Gateron Brown switches, which provide feedback and don't require much force to actuate. If you need a dedicated Numpad and navigation keys, the C2 is a better choice. However, if you want something as compact as possible and want to pair with multiple devices, including mobile operating systems, the K12 is a better option.
