Our Verdict
Keychron K4
ROYAL KLUDGE RK61
The Keychron K4 and the ROYAL KLUDGE RK61 are different types of wireless mechanical keyboards. The Keychron is a 96% keyboard, so it has most keys compared to a full-size one, including a numpad and dedicated arrow keys, which the 60% RK61 doesn't have. The Keychron is better for office use because typing feels better with the LK Optical Brown switches, but the RK61 is better for mobile use because it's smaller. The Keychron is available in a variety of switches, but the RK61 is hot-swappable, so you can use whichever switches you prefer.
