I am looking to figure out the charging solution at my son's house. They will be renting for another year. When they buy a house I will ensure they have a conveniently located 14-50, but till then I must choose between an easily available 110v or a 10-30 dryer plug which will require a 50 ft extension to get to their front door which the Tesla mobile cable can also reach. Try as I might I have not been able to find a 10-30 extension cord that will work for an outlet that looks like this: What I can find is an adapter from this page http://www.evseadapters.com/adapters-for-tesla-model-s.php that will bridge from a 10-30 outlet to a 14-50 extension cord, which are readily available and which can hook up to the Tesla mobile cable. Does anyone have any experience with this? Disclosure: I am aware that the Tesla manual advises against using extension cords. I am also aware that according to the forums, it has been successfully done a number of times.
