I don't have access to outside power at my apartment complex //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I'm thinking about getting a solar panel with a small charge controller, though...mount it inside the windshield, at least it'd keep things topped off for when I don't drive for a couple weeks. I have several two-way radios installed that draw a couple mA even when powered off...when I'm smart I just pull the main fuse that they're on if I know I'm going to be parked for a while, but sometimes, I need a low-voltage idiot switch //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
