The Chargpoint I used yesterday said it was "6.6 KW per port " and had two ports. So that means that J-station  can do 13.2 KW (or up to 55 amps). I am glad to see that the newer charge stations don't drop the power when two vehicles are charging from the same two-port station. This means I can charge from this station at all the power I want as I can use both ports from the same station. This new J-1772  stuff getting as good as most Tesla destination chargers at least when I can hog them both.

You will never get 13.2kW from a single port on those type of stations.

Also I can't help but notice you stopped reading the wiki page at, literally, the first paragraph. The next paragraph reads:

Quote
The CARB regulation of 2001 mandated the usage of SAE J1772-2001 beginning with the 2006 model year. Later requirements asked for higher currents to be used than the Avcon connector could provide. This process led to the proposal of a new round connector design by Yazaki which allows for an increased power delivery of up to 19.2 kW delivered via single phase 120–240 V AC at up to 80 amperes.

The round connector that nearly all use now, Vetter?

As long as I bring two J-adapters I can use almost 8 KW from both on the same pole (newer stns) , which is all I care about.

I read it, but I don't care about "proposals".

That somehow reminds me of Lightning motorcycles  . . .

Just looked it up.  Yes, that is EXACTLY the connector.  The original J1772 standard called for a rectangular connector.

I was pretty sure we used the round connector that's beefier than we needed ^-^

EVSE circuits are not rated in kilowatts in N. America where the AC voltage for L2 varies and can be anything from 208Vac to 277Vac. What some of us are confused by is a reduction of information when the correct data is input into EVSE-finding apps and website services so that you can easily sort through to find the most capable EVSE.

For example, Plugshare entries largely come from Tesla owners as they are the hot flavor of mass-production EV; the car doesn't tell you anything about kW (at least not in my Model 3 and I don't recall anything like that in the Model X or S), instead you get amps and volts as it should be, and when input into Plugshare it does the math and reduces the information to kilowatts. Further complicating things is that Chargepoint does this same reduction of data on their graphs and billing reports.

Lemons make lemonade. Apples make apple juice. Fruit makes fruit juice. What fruit is in fruit juice? Nobody knows!

**correction** the Tesla UI on Model 3 and Android app does list kW/V/A all three. Powered from JuiceBox40 J1772 on home inverter. Screenshots:

Also my apologies I don't have compatibility with CCS on this vehicle so I don't have value to add to this discussion about CCS and EV motorcycles.

I don't see why the average driver cares about anything but the watts.

Sure, the EVSE really only cares about the melty melty amps, but...
