I added an extra question to the OP to comply with the "portability" issue.
As like any other electronics, leaving it overnight via car battery will drain it. As for it being a chore, you simply drag the pad to the other side of the windshield to the hook and then plug it in. I'd assume that's considerably less effort than going out to scrape off the ice in the cold.
