Hi, I have a 240v outlet in my basement but my car is more than 20 feet away so I need to use an extension to make this work. Not an expert on this but Tesla says not to use an extension cord with the mobile connector. I wonder if something like this is safe to use since it seems like it's designed for use with EVs. I found this NEMA 14-30 Extension Cord for Level 2 EV Charging (30A, 250V)

The warning is because the extension cords most people have laying around uses 16 gauge wire.
A 50 amp cord would need to use 6 gauge wire. A 30 amp cord would work with 10 gauge wire although I would use 8 gauge wire for a lower voltage drop. Energy used to heat the cord is not going to go into the battery.
