It has a 150 PSI max vs the M12 120 PSI max. I'm not going to run out and buy one but on the off chance one of my m12 inflators takes a dive, I'll replace it with one of these m18 units. I like the fact that it has presets. Nothing else about it is calling to me to upgrade from my m12 inflator. Not that I care but, in before someone else complains it isn't packout compatible lol.
