It is not really waterproof but you do not care about it. I forgot it in car before a ford forcing a many time. Just dried and cleaned from swamp slime and no problem. One moment what no voltage supply to it in this cases because all auto electrical circuits below roof certainly was disconnected.
P.S. Car adapter is not sealed and you can see yourself that is inside.
