I live in New England, and we don't have a garage. I got tired of my e-Golf's charging port getting filled with ice and snow every time we have a winter storm, and I happen to be plugged in in our driveway. So I ordered one of these from a place up in Quebec. Uses magnets to attach to the car and a velcro flap to seal the cord entry. Looks a little clunky, but it works like a charm.
