This portable air compressor is very powerful, I have a Sienna minivan so we'll take it with something in case happened at the puncture, the recommended pressure for my van's tires is 36psi, so I drained 10psi from the rear tire to try it, it worked fine in less than a minute, the tire is 10psi from this portable Compressor returned, LOWER SIDE - The length of the power cord is too short for a minivan, the battery is in the front on the driver's side on this Sienna. So if your flat ends up on the rear passenger side you won't have enough cable to use the compressor, it's very short, it needs at least 2 meters more, I'd pay a little more for an extra cable, so on my I have to have one buy new cable and REPLACE it. But overall a great power supply. PLEASE SOLVE THE PROBLEM. THE POWER CORD IS NEEDED AT LEAST 60 cm MORE
