What do people recommend for adaptors to remotely charge your Roadster at a public remote charging station at 220v or more? Are there options to charge at a Tesla Charging Station? I see there was a Tesla UMC at one time. And a Henry Sharpe makes a CAN adaptor. What are most people using? Are there any available or do I need to to try and find a used one. I have a 3.0 battery.
