I was wondering if someone more electrically inclined could figure out some type of device that would combine two 120V outlets and turn it into a 240V so that you could charge faster. What I'm imagining is if I went to a friends house or somewhere that didn't have a high power charger. I could use 2 extension cords and plug in two 120V plugs into a small device that would combine it to make a 240V. The extension cords would have to be plugged into different breakers since most house breakers have a 15 amp capacity. Is this possible?
