I bought this quite a while back, and used it several times with great success. I've since changed vehicles and this device simply doesn't work with my new one. We connect the hose, plug it in, set the psi, turn on the pump, and it blows the outlet fuse after maybe 1 second of the pump initiating. The new car has 3 different outlets, all with amperage rated at or above what this pump states it requires (and at or above what the inline fuse on the power cord is rated for), and each one blows out almost immediately when the inflator pump is turned on. Inline fuse on the device hasn't blown yet, probably because it killed the fuse in the car first. If you purchase this I would test it with your car before simply putting it in there as your "in case of emergency" unit, because it may not help you in an emergency if you have the same issue.
