Hello, I am eagerly awaiting my new e-tron! It should be arriving mid-week. I am also new to the EV scene. I know I need to have a 240V plug in installed in my garage. Also working on figuring out which home charger to get. I am considering the ChargePoint home flex charger. Can anyone tell me what is better to get, the NEMA 6-50 or NEMA 14-50?
