pumps are 2-3 times faster than conventional mini pumps of this type. However, it draws a lot of current, I measured about 12A. I find it best to use clips and attach them directly to the car battery. It also worked well on my 18ft caravan with its 12v supply. These tires are 50psi but are pretty small. As others have said, the cable is too short. Even on my tiny Chevy Bolt. I couldn't reach all the tires when I buckled up the battery. I was about 2 feet short. So I modified the cable to use 12 AWG wire and doubled the length.
