Device of a great brand but ineffective. 2 small engines, one operating on AC 12V and the other on. Well suited for inflating small objects, but when it comes to inflate a car tire (which is why I bought it), it heats very quickly and hardly get to the end, so that one has the impression that he will give up the ghost. It must be stopped, let it cool and repeat. In addition, the manual advises to make it work on 12V engine running.
