What makes this product unique is that it can be used for many purposes. In addition, it can be connected to a DC 12V car cigarette or at home with a regular wall charger to inflate most things. Both cables are present. There is a bright LED light that can be aimed precisely at the tire valve when inflating. This is very useful, especially when it's dark. The LED light is perfectly positioned. The DC cable is long enough for a sedan and you can easily go around 4 corners. It took about 50 seconds to inflate one from 28psi to 33psi. It turns off automatically when the required level is reached. There are 2 buttons (-) and (+) to set the desired pressure. It is a necessary product in every car. Like most other tire inflators, it's a bit noisy, but that's to be expected given its heavy use.
