VEVOR 10.6 CFM Heavy Duty Air Compressor, 30s Fast Inflation | Dual-Cylinder Portable Tire Inflator, 12V 150PSI Offroad Air Pump with Adapters for Trucks Car SUV 4 x 4 Vehicle RV

So far so good. The unit doesn't have a pressure switch so you have to modulate tire pressure by turning the unit on/off. Fills up little tires FAST. Fills up larger tires at a very reasonable speed. Draws a lot of power so connect direct to battery. Loud enough to notice but not enough for hearing protection if you have a little space.

This is truly an air compressor to always have with you. No it's not the cheap little one you plug into your cigarette lighter and wait 30 minutes to air up your tire. This is a high quality professional type double headed monster. It connects directly to the car battery, it's a beast that needs to be fed to do the work. And it works hard and fast. It has no issues inflating the 33 inch tires on my truck. There would be no issues inflating a semi truck tire if that's what you have.I carry a plug kit for tires to go along with this air pump. Once you've had a nail in your tire in the middle of nowhere (no cell service) this bad boy pays for itself. Just something to think about. Spend a little more for knowing you'll have the right tool for the job. Have you checked your spare tire lately???

This thing is a beast. It inflated my truck tire from 40psi to 70psi in two (2) minutes and barely got warm. I purchased a different one as well because it was advertised to perform well. That one took eight minutes to do the exact same thing and was pretty hot. If you want one on the chance of having a low tire get the little one. But if you regularly increase/decrease tire pressure get this one. Beware it is not tiny like the other ones and weighs 24 lbs! See my photo.

Fills my 35” tires from 20psi to 40psi in about 1 minute per tire. Pulls a lot of current, estimated to be 60 Amps. Be sure to have your engine running while using. Good idea to start the compressor before connecting its hose to your tire. The power cord runs hot, I’ll probably replace it with a more capable cord, that heat represents lost voltage at the pump motor-electric motors hate low supply voltage. I don’t like running that kind of amperage through the included battery clips—have replaced them with an Anderson PowerPole type connector pair; a significant improvement. Made a converter that adapts it back to battery clamps for emergencies. The brass hose connector bits are [very] hot after airing up 4 tires-be careful. It’s physics, the manufacturer can’t do much about it. You will have to let things cool off before putting it back into its case. Have only used it 3 times since purchase so can’t speak to its durability but so far so good. Hard to justify paying $1k for other compressors.

Used it the first time after coming off the beach. Worked beautifully. Filled 4 tires from 16lbs to 36lbs in less than 10 minutes total time (uncapping, filling, moving to next tire). Plenty of pressure. As others have mentioned, the metal connectors get hot, as do the pistons. I attached my own filler nozzle and gauge after reading the inaccuracies from other reviews. Very happy so far. No more searching for air stations that never work anyway!

Great quality

Perfect for off roading use. So far about 20-30 uses at about 5 minutes each time. Fills 33in tire from 20psi to 40 in about 30 seconds. I think the gauge is off though. Faster than any of the other similarly priced air compressors

This pump is POWERFUL. I use this pump for the on-board air system for my Suburban to air up and down tires for offroad in conjunction with a 4 way splitter to do all the tires simultaneously. It inflated all 4 33" tires from 10psi to 40psi in just under 5 minutes. This makes my oil Viar pump look like a toy.
