    This snip is from Plugshare:

    Is this compatible with my Tesla Model S?
    Does the 30A refer to that other protocol?
    Thank you.

    It will work on your Model S using the J1772 adapter (that comes with the car). 30 Amp means it is the charger's maximum output in Ampere. 200 Volt at 30 Ampere means you will get roughly 18 miles per hour of charging.

    This is a standard J1772 plug (compatible with your car using the provided adapter). 200V 30A refers to the power (~6kW) provided via the unit. So giving you ~15 milesofcharge per hour.

    Hi

    The key word you are looking at is "J1772" that mean that you just need to use you adapter that came with the car
    Other Important information is the 200v 30a you just multiply them 200*30=6000 with result in 6Kw
    Meaning that a single charger will be fine as it is less than 10Kw

    Thanks, this is a useful thread. What is the math that gets you from 6000 to 15 miles of charge per hour?

    electrical Power is measured in Watt. Volt * Ampere = Watt. 200 Volt * 30 Ampere = 6000 Watt = 6 kW.
    electrical energy is measured in kWh (kilo Watt hours). energy = power * time. 6kw * 1 hour = 6 kWh

    The Model S needs about 300 Watt-hours for each mile driven. 6 kWh divided by 0.3 kWh/mile = 20 miles. Since charging isn't 100% efficient you have to subtract about 20%. 20 miles less 20% is approx 18 miles.

    The car will do the math for you :) If you plug in wait a few minutes for the charge to ramp up to it's max and then you will see the charge power either in kW or in miles/h depending on what setting you picked in the settings for 'Units"

    This website gives you information about charging at different rates:
    Tesla Charging | Tesla Motors
    The main thing you need to know is charging plugged into a NEMA 14-50 at 240V, 40A (9.6kW) gives about 28 miles of range per hour of charging. For lower voltages and/or amps you can set up a ratio to find what range you should expect per hour of charging. As a rule of thumb, public 30A J1772 charging stations give about 18 miles range per hour. The one you cited is only 200V which is unusually low voltage so it would be a little less than 18 (someone did the calculation and got 15).

    "Quick Charge" and "30 Amp" fooled me.
    Most listings are "6.6KW" which I realize now is the same thing.
    (I am going to be on the road without a SuperCharger. Ugh!)
    Thanks again.

    The information in the listing: "Ports: EV Plug (J1772), Quick Charge" means that there are two different connections. One is J1772 (that you can use with Model S) and the other is "Quick Charge" which in current PlugShare vernacular means CHAdeMO Quick Charge, which you cannot yet use with Model S. Tesla should be releasing the CHAdeMO adapter soon. It has been in testing for some time, but it costs $1,000 and you must have SuperCharging enabled on your car. Here's a crop of a PlugShare picture with the two charging stations labeled.
