Review on Dual Cylinder Air Compressor Pump by FORUP - High-powered Portable Air Pump, 150 PSI, LCD Backlit Digital Display, Automatic 12 V Tire Inflator for Car, Truck, RV, Bicycle and More Inflatables by Dan Buycks

I have an F250 and was looking for a powerful little emergency lung pump. It is great. Although the cigarette lighter fuse may have blown. That's because it's powerful. I usually connect it to the trigger with alligator clips. I like that you can adjust the pressure and go. Some guy is talking about trouble starting 33s. Well, it's a huge hoop. If you have a regular tire you need to hit 60psi, that will get the job done in a surprisingly short amount of time. It's very accurate. I checked with a digital tire gauge after inflation and it was accurate. I paid $39 and see it's now $46. I recommend it anyway.
