Does the cord draw power when phone is not plugged in? My car battery was drained and the only thing I could figure out was that this cord was plugged in for a couple of nights while the car sat unused. Does it continue to draw power even when a phone or other device is attached? Obviously it does draw power when it is first plugged in, because the lights run for a while, then it appears to go to sleep. So, in that sleep mode, does it still draw power? How much?

I have not had that issue. I can't see how the diode lights drained a battery, but maybe the car battery was weak.

I have left two of them plugged in for a week in my truck and no problem. The amp draw is so low that it would take awhile (30 days) to even show any draw.

No it should not ! I have used many chargers in my car in power points it never drained the battery

Some car manufactuers allow the charging port to stay on even after the car is turned off - others power down when the car is off. You should do a test run once your car battery is charged again. Easiest way to find out.

Not unless your phone is still plugged into it. If it is then it can if your car plug still charges when the car is off. If not then no it doesn't. Even if it did it does not pull enough power (even for a few days) to kill a car battery.

No. It shuts itself off when the phone is fully charged.

The cord does not draw power unless it is plugged into something like your phone or tablet. Even if your tablet or phone is in sleep mode and is plugged into a power outlet it will draw power to charge the battery. The phone or tablet may also draw power during sleep mode to do updates, but I'm not sure about that. SO if you don't want it to draw power don't plug your device in.
