I was in the backseat of my EV6 while my wife was driving us to our in-laws, and I wanted to plug the laptop into the outlet below the rear bench, but I didn't get any power out of it. I went looking for info in the manual and on this site and I'm only able to sort of deduce that maybe this outlet only works when the car is not running, unless I'm misinterpreting. Which, if true, is not helpful. I can't power a laptop off the USB-C charging ports, and I'd really like to be able to at least hold my charge steady on a long drive when I'm using my Mac, but it looks like I can't do this via the indoor V2L outlet. Am I wrong?
