please forgive me, i know nothing about inverters/electricity/voltage etc... i usually charge at my home with a NEMA 14-50, and all is good and fine. i will be traveling to visit a friend with no public chargers nearby and will charge at him his home. he has had other friends with teslas charge at his house and claims that with a NEMA 14-30 adapter plugged into the dryer they gets max 6 miles per hour. he wasnt 100% sure, and im hoping he has that stat wrong. i have another friend with the same setup and claims that he gets 20-25 miles per hour....he states that at a minimum he house should be pulling 40Amp, and give anywhere from 20-30 miles per hour charge. why the difference? does it depend on what kind of tesla you have? or does it depend on the house? im including photos of the adapter and dryer connection for my friend who claims 6 miles an hour...anyone have an idea what i should be getting per hour charge?
