I've had this device for a few months now and use it once every two weeks. This beautiful and compact device fits in the corner of the trunk. The power cord that plugs into the cigarette lighter is long and plentiful, if I had an SUV with a tire on the trunk I would reach that too and with plenty of room. It only takes a few seconds to increase a psi by, say, 5 pounds; I think it takes about 3 minutes to inflate from nothing to full. There are also no leaks from the flow during operation.
