Two criticisms though, it only works on 12V, so no possibility of it plugged into a 220v.
I knew it by buying it, but the use is mandatory when you want something other than inflate his car (a bike or balloon for example) having to go next to his car to open it ..
Also the cable is not very long, enough for all the cars I think, but 2-3 meters more would have been more comfortable.
