^^ Well, it is powered by exhuast and it isn't like I have a wimpy little Jeep motor
I actually took that picture the same day I saw you out there btw!
In all seriousness though it was a quick fill, once the seal was snug on the tail pipe it couldn't have taken more than 30 seconds to get it fully inflated to the underside of the frame; however I had to get somebody to jump into the truck and rev up the motor to get more pressure and to lift up the truck. Once the the revs were up it took like 10 seconds to lift the tire 6" in the air. Setup and breakdown for it is fast too, it is a pretty neat product.
