For people who want excellent quality

Heavy duty. Hooks up to the battery and the vehicle should be running as this draws some amps. I use mine to de air and re air my truck tires when driving in sand and anytime we need air in any of our tires. It's the best portable air compressor that I've ever owned.

i had a viair that worked off of the cigarette lighter-and it was junk.but this 440P is a whole different animal. It can blow up a big tire in no time at all, with PLENTY of capacity before it blows its thermal trip.downside is you have to clamp directly onto the battery.Also, for small tires, you have to be ready to turn it OFF before the tire blows up, it moves that much CFM.Clearly well made.I guess you could get a ARB that is even better, but you are spending a lot more money for it.

I have two small air compressors hooked in the back of my jeep that would take about 12.5 minutes to fill to 120 psi. This compressor does it in 4 minutes. I hooked it up so I can run them all and it keeps me in air for airing up tires and it works well.

I use this for offroading, and it works fine for filling my 33 inch tires.

Pumped up all 4 tires, 245/75R16 (30.5"") from 25 to 60 in a few minutes each. Compressor was still cool enough to touch. Easily reached all 4 tires on my 20 ft long campervan.Again pumped up 2 tires on a freind's van and 4 tires on mine. Just had it off a couple minutes between vans. Got slightly hot this time but still able to put it away. I don't use the bulky case.

This is a great little air compressor. Fills up my 37"" tires quickly, and setting it up takes a few min. It's a real life saver.

We had a lower model by this brand it would get hot when tryping to inflate our 35"" Nittos to 35 PSI. This one is seriously FAST and never heats up by the 4th tire. We are amazing each time we use it offroading! Highly recommend!
