    Picked one of these up from Amazon today, noticed that it has a red light on it even when the car is off. Is anyone using one of these? Do you leave it plugged in all the time? Didn't troubleshoot further but I'm afraid it's going to drain the battery, and I don't care to unplug the thing every time I want to use it. Thanks!
