I may rent a place in South Florida, and since it may be in a highrise condo that may not have charging, would have to rely on Superchargers. The nearest (probably in Aventura) will only charge at up to 72kW vs the 120kW I have used in CT. How does that impact charging speed...will it take 120/72 (or 1.67) times as long, or is it some other number?
