I just installed a wall mount charger along our driveway outside. I know it is supposed to be waterproof, and It's semi-protected by an overhang, but I have a hard time believing water won't get into the slot that holds the handle, then into the charge port... I'm considering putting a circular piece of neoprene rubber with a slit in it over the opening the handle goes in. Any thoughts? Is there anything like this in the after market?
