Hi all, I've always wondered, I've bought an adaptor so I can charge my phone whilst driving. Am I able to leave this plugged into the outlet when the car is not running on locked. For example, when I arrive home and disconnect my phone from the charger do I also need to unplug the cable from the outlet to make sure it doesn't flatten my battery. It's always something I was never sure about but I've never asked. See attachment, Thanks in advance.
