Is anyone familiar with an AC to 12 volt DC power supply that is sufficient to power a heavy duty portable air compressor? I'm familiar with bench top style AC to DC power supplies intended for electronic projects, but nothing that would be sufficient for a portable air compressor. The specs for my air compressor (ExtremeAire High Output) is 3/4 HP, continuous duty cycle, max 49 amp draw. The compressor normally connects to a vehicle with alligator clips, but it would be easy to do a DIY solution to be compatible with an AC-DC power supply since my compressor has an Anderson connection. Thanks in advance for any suggestions.
