We are traveling to a cabin in GA. We know there is a NEMA 14-50 outlet there on the main level, but I don't know the distance. I am pretty sure I am going to need an extension cord. Is that even possible to do with the mobile charger? If so, what type do I buy? I read that extension cords can impede the charging rate. Has anyone else done this successfully? If I can't get to the dryer outlet, it looks like I am just going to have to use the 110 on the porch. I would really like to not have to do that. Thanks!!!
