This portable air compressor has proven very effective for us as both a sedan and SUV. The compressor quickly restores a falling tire pressure. For example, on my car, the air pressure light came on and the device was able to read the current pressure (25.5 pounds) and fill the tire (36 pounds) in less than 45 seconds. The cable is long enough to reach each of the four audio/video connector bars and the cable is included. The display is bright and shows the progress as you use it. It also remembers the pressure reading of your first tire and all you have to do is plug it into all your tires and everything will be in perfect condition again. Ideal for autumn as the cold usually affects tire pressure. Finally, it features an automatic shut-off that takes the guesswork out of it. In view of the low price, we can definitely recommend this compressor.
