Just received it! I’m in Chicago and it looks like they have a distribution center in IL they are shipping from.

The problem is they are either Tesla or Clipper Creek in which case the property owner must pay for the power which adds up over time, or they are ChargePoint or Blink and cost an arm and a leg upfront, and always break and no one feels the compunction to fix it.
If we could find a cheap way to blanket parking lots with chargers that could bill the person plugging in, that would be genius. {maybe check out the link}

The Korean web page does not say 150kw, in fact it doesn't mention any KW that I can see.
The selling page (translated) and the support page (translated) only show
Rated:
500 Vd.c, 300 Ad.c.
Spec's are the same
Voltage 500V DC
Enclosure Rating IP44
Operating Temperature -22°F to +122°F (-30°C to +50°C)
Storage Temperature -40°F to +185°F (-40°C to +85°C)
What is the North American version part number?
The Korean one from the order page is 1656565-10-A

My order just shipped, looks like it's coming from Lathrop CA. Should receive it early next week.
Yes, 500v and 300 amp DC is 150kw which is why I find it interesting that they say 250kw for NA.
Someone that has received North American version can post a picture of the specs?

Maybe, but 250kW is possible today with 650A when the battery is at lower SoC and around 380V
Also, I’ve never gotten more than around 70kW regardless of what they are rated with the SK adapter. I’ve tried ChargePoint rated up to 125 and EA both 150 and 350. I doubt the US version is different but l will check.
An online volts to watts calculator confirms that 500 volts at 300 amps (DC) is 150 kW, whereas, for example, 500 volts at 500 amps (DC) is 250 kW.
So, this is intriguing.
Are there true, substantive (internal) differences between the South Korean (PN 1656565-10-A) and North American (PN 1656565-00-A) Tesla CCS1 adapters?
Or, are they basically the same product, but in the years since the original Korean introduction additional testing has adequately demonstrated (to Tesla and/or NA regulators) that the the adapter can (and has always been able to) safely handle higher power levels in Canada and the U.S.? Or perhaps Korean electrical reporting requirements are more stringent and electrical ratings have to be more conservatively reported there? Or something about the North American electrical grids differs from that in Korea, necessitating the different ratings? (Just speculating, here.)

Can't prove this, but I suspect the 300A is a continuous rating rather than peak. The cars typically don't sustain 250kW for very long. The adapter does have a thermal breaker built in, so theoretically it shouldn't be possible to get to dangerously hot temps regardless.
Would be curious if the weight between the US and Korean versions is any different

I've used the "Korean" adapter on two road trips since early June. 150kW EA sites gave our MY around 135kW of juice, 350kW units gave us over 180kW. Too lazy to look up my notes sitting in my MY.

Good point--i.e., potential difference between "continuous" versus "maximum" ratings. Anything available to confirm that hypothesis?
Yes, me too. Does the size of the (copper, I assume) internal connectors vary between the two (Korean and NA) versions?
BTW--and this is total speculation on my part, without any evidence--but I wonder if all aftermarket adapters use equally heavy internal connectors as the Tesla OEM adapter? Am I right in thinking I've read reports of warming (to the touch) during charging with some aftermarket adapters. Whereas the Tesla adapter stays neutral to the touch? (Granted, if true there could be more than one reason for that--e.g., size of contacts or clever use of internal thermal insulation.)
Not only would comparative bench-top dissection of Tesla and third-party adapters prove interesting (but expensive), but a much less destructive competitive "weigh-in" (in this case, the "winner" would probably be the heaviest adapter), might be very illuminating. (Any volunteers? To implement such a contest, I recommend taking a portable small-item scale to your local CCS1 charge station.)
