Rare post for us since the car has been quite exceptional. As we're between homes for a few weeks we've had to use other means than our old homes 240V 40A service. But having now tried 4 120v outlets w/o using an extension cord and a Chargepoint station the car gives us a warning triangle and says to "close charge door, step on brake, open door and try again". It tries to charge for about 5 seconds and then the light goes from green to red. Any thoughts on if this is the car or the power we need to pay attention to? Called into Tesla, but been holding for some time. thanks all!
