Your bid is fora new, in the box, portable air compressor. I asked for one for Christmas, but I got 2. It’s great to keep in your car in case of a low tire. It can be charged up with its USB cord, or plugged into the “cigarette lighter” in your car. The unit itself is 5x 3 X 2 inches. It’s small but mighty, and has a digital read out. ( fits in my glove compartment). It comes with instructions, USB cord, card to plug into your car, a drawstring case, and adaptors to blow up balls, air mattresses, etc
