12 volt compressors

Viair will do it. You get what you pay for. 7 years and still strong. Hooked to my truck train horns with a receptacle on my bumper for air filling of tires etc.

I asked the same question HERE. Perhaps the conversation will help you. I still have not purchased one yet.

I don't know the brand off hand, but I bought one once at a truck stop that works okay. But I have 22 inch tires that need to go up to 100 psi. I paid about $140 for the pump and it works, but it won't win any speed contests. It probably took it 20 minutes to take a tire from 85 psi to 100 psi once.

Viair.

I'm wondering if you could use a 120V unit with an inverter. It gives you the power of the 120V units working off 12V battery power?

Yes I can use our ac air compressor with our 2000 watt inverter and also have the viair 400P but it is slow and needs to be off to cool down. I think I read some now are better for a longer run. the viair was for adding air not from flat to full pressure.

I use a Viair 380C duel compressor systems with a 3.5 gal tank. It runs the air bags, an impact wrench, can air up tires of any size.

I use the MV50 on Amazon for $60. Works great to at least 80psi. I am confident that it will work right to the 150psi rating although I would expect it to slow down some as any compressor will do. Tops off my tires plenty fast. The MV50 clamps direct on the battery. If a compressor has just a cigar plug it is going to be weak. Viair is top line and a little more money.

Harbor Freight has a pretty decent one for about $60 if I remember right. I've had it for about 3 years. It takes my air bags to 100 psi in just seconds, obviously much longer on tire inflation. And it does get hot.

But then, the process of compressing air does create much heat, as releasing compressed air drops air to freezing temperatures. That's the process of refrigeration.
