i would never just leave the phone on the charger all the time ??? But the holder does draw power while it is plugged in and has an LED on it. As I don't drive it for months i don't want any parasitic draw. I thought this was a simple yes/no question as to if the power outlet could be set to ignition only and not on all the time, But I guess it got side tracked. I have my answer, Thank you all, and I have my solution.
