I have a 2HP 8 gallon 120v compressor now, I want to be able to run air tools off of my truck. I'm thinking of just running this off of a 1,500 or 2,500 watt power inverter. I can't find anything that tells me how many watts a 2hp compressor actually draws. And whether the power inverter would be the best option, or if I should consider a gas generator. Or if there is any such thing as a decent 12v air compressor capable of running air tools.
