    I will be stopping at the La Posada hotel in Winslow, AZ. They have a HPWC, and the notes say...

    "The Tesla HPWC charges at 16.8kW per hour."

    I think in miles of range added per charging hour. What is this charge rate in miles per hour?

    Very roughly, full 20 kW is 60 mi/hr of charge, so that would be 50 miles/hr of charge.

    I hope you have a dual charger, or you'll be limited to 10kW/hr.

    The equation would be at his location 59/20*16.8 = 49.5

    Few people have true 20 kW. I get 60 mi/hr at a true 20 kW (250V service * 80A, although some is lost to the cable dissipation). Most people have 19.2 kW (240V * 80A). So 59/19.2*16.8 = 51.625.

    But either way, it's close enough to estimate it at 3 * kW.
