12v AIR Compressor -What is good
I need a new one I am looking for a 12 volt air compressor that has clamp on terminals to a battery that is good for 100 PSI. I don't want one that plugs into a 12 volt receptacle. I also don't...

I just retested mine as I had it, and my dc clamp on Meter out anyway.
When first turning and little resistance, 15 psi, it draws 19.27amps when battery voltage was 12.35.
By the time it got my suspension airbag to 100 psi,about 25 seconds later, it was drawing 15.47 amps.

0.18 amps of that is the additional 80MM fan I attached to blow over the head
I expected the opposite. Higher amp draw at higher psi. Motor actually speeds up at higher PSI as amps drop.
My wiring run is a bit longer with about 10 more feet of 10 awg added where I snipped off the alligator clamps.
2nd test,
I just pushed the other airbag to 100 psi from 15psi. It briefly read 37 amps right after flipping the switch, but then then settled to 19.27a. It then slowly rose to 19.8a, and about the 45PSI level, amps began dropping, at 100PSI, 15.27 amps.
