I've gotten two of the devices connected in the same car. My main point was at the beginning of the small dimensions, since in my car is not really a lot of space. The good experience and performance (I load including two iPhone at the same time without any problems) have now led me to the second, which must as a power source installed behind the panel for a mobile wireless router serve. I would take the adapter again and wonder why other devices on the market can still exist with the dimensions of a small beverage can ....
