Any idea if this could cause battery issues? I usually drive my car every day but I've never had anything like this stupid charger with a light that is PERMANENTLY on. My cigarette lighter port is powered 100% of the time, even when the car is turned off, locked, etc. This also seems like a theft issue to me... it's just a stupid charger but that won't stop them from thinking "OMG SHINY BLUE LIGHT, MUST BE FANCY STUFF INSIDE!!!" Any way to turn it off other than breaking it?
