What will you mostly use it for?
The K3 Pro is the more practical choice for office work and programming because it is a complete 75% keyboard, while the K0 Max is an auxiliary numpad. For travel, the K0 Max's smaller dimensions and lower weight favor carrying it as a separate keypad. Modding is evenly matched on the listed QMK, VIA, and hot-swap features. The K0 Max's macro column and knob give it an edge for configurable control tasks, and its 2.4 GHz connection sets it apart for wireless gaming.
Pick the Keychron K0 Max
- The K0 Max supports 2.4 GHz wireless with a stated 1000 Hz polling rate.
- Both models list 1000 Hz polling, and the K3 Pro vendor specifies that rate for wired mode.

“Perfect addition to my Nuphy Air75 v2. The keys line up well, and this gives me a knob and 10-key when I’m at my desk!”
“The K0 MAX is just right with its red Gateron switches! Typing on it feels really natural. 2 Stars less because the battery needs to be loaded again after 3 or four days of occasional usage.”
Keychron K3 Pro

“For anyone buying this, remember to toggle the switch to the correct operating system. Other than that, the feel is good and it comes with a good feature set for a low price”
“I was happy at the beginning but after few months of use I'm getting more and more frustrated. Keyboard just hangs sometimes and I'm not able to connect with BT. I use it to operate two laptops and using Fn+1 anf Fn+2 combination is great... when it works…”
