Depending on What you are trying to drive and how clean the output is results may vary, I would not try to flat out test our drive line this year as wheels up with 4 motors and the drive line friction, we pull 20 amps a side, total over 40. (yes I know it should be lower) If your just running the air pump and motors one or two at a time with no real loading, 30 with regulation to a real 12 or 12.5 not the normal 14 that comes out of some 12 v supplies. Life will be good. Btw Sony makes a Camera power supply AC-500. It's a switch mode that is very costly new But can be found on E-Bay, I had one, I fixed years ago, and it would Supply over 30 amps (tested) even though they are "rated at about 7" It would not start up with that kind of load on it but took it over night on a resistor load. Reason I mention this is Switch mode will be lighter and portable camera power supplies like this are clean and built to take the beating video crews put on them.
