I couldn't find this info already posted when I searched for it. So forgive me if it has already been mentioned. I recently got back from a road trip out of Supercharger range which was kind of painful. At the condo I stayed at I considered it would be possible to have charged via the dryer outlet if i had the adapter and an extension chord. I wanted to order both the Tesla Chademo adapter, an 14-50 extension chord and a 14-30 adapter for dryers. Well lo and behold EVSE Adapters.com has a universal extension chord that was designed for EV use that will fit both the 14-50 or 14-30 plugs, so need to carry multiple adapters. Heavy-duty NEMA 14-50 extension cord for Tesla, 20 ft.
