So, when not in use is the protocol to leave the adapter and cable plugged into the outlet or unplug it? When mine is plugged in the Tesla letters display a green color which, I’m guessing, is still drawing power even though it’s not plugged into the car. If it’s ok to leave plugged in, then also I am taking a wag at it that it’s barely moving the electric meter needle. See attached image. Thanks for the assist.
