I keep mine in the storage area underneath the armrest. I also toss a towel in there to cushion the adapter, although I do not expect it would get damaged in that nook.

"Good news, everyone!"* (Who bought a Korea adapter, that is.) It appears that there is no significant weight difference.
A side-by-side weigh-in would still be nice. Maybe also compare Korea vs. NA resistance/ohm readings? And of course charging rates at the same station.
I can bring my Korean adapter and meet someone with a U.S. adapter (at, say, a free EA location) somewhere near Davis, CA, USA. No rush. I expect there to be no difference.

Hmmm…..
I have the korean one, and its 1 lb, 12.9 oz. So yeah, about 1.81 lbs. same weight. I’m wondering about the power rating labels though. Doing the math, 500V x 300A = 150kW. The US model states 250kW right on the adapter. Then again, I’ve pulled a little over 180 for brief periods when charging before. So They’re probably the same. Same country, taiwan, same manufacturer, Pegatron.

Well, my lad, you have come to the right place. (Ha, ha.)
I can supply you with a Harumio, Amazon, Harbor Freight or other type of case.
Coincidentally, just posted this.
Also, see the Original Post from that Thread here.

I doubt you would see any difference. The only way to really check would be to measure voltage loss under load, but that isn't easy, or safe.

I put the 'adapter' in the driver's door cubby in my Model 3 with my J1772 adapter at the back then the CCS (Tesla connector down) and then a thermos of water in the drink holder. Super convenient, just pull it out when I am getting out of the car to charge.

I ordered late in the day on Wednesday and tracking predicts a Tuesday delivery (in MN). So, it looks likely that everyone who ordered on opening day should get theirs by early-mid next week.

You can measure resistance directly with an ohmmeter. Since it's DC, capacitance and inductance do not come into play and can be ignored, and voltage drop increases linearly with current (V=I*R). Power dissipated increases with the square of the current (P=I*V=I*(I*R)=I^2*R).

I also ordered about 7pm Eastern time on Wednesday, got tracking email on Friday, and now the tracking link says the shipment has been picked up from the shipper, and should be delivered to me, in North Carolina on Tuesday, as well.
I think his point is the resistance will be low enough that the meter won’t be able to tell. It’ll just register as 0. The actual probes will have more resistance than the adapter. You’d likely need something that can measure on the order of microohms, which is going to be laboratory grade stuff.
I have an under seat drawer under the driver seat. Both CCS and J1772 adapters lie in there. Just remember to push it back before stepping on them (did a few times at the beginning).

I have both the Korean and North American Tesla adapters. NA one arrived yesterday. They are identical in every way. The box, packaging, labeling, etc. is all identical. Both weigh exactly the same. The only difference is the label on the bottom of the adapter is in part Korean vs English obviously. Both manufactured by Pegatron. Slight difference in wording on the bottom regarding 250 kW on NA one and 300 amps on Korean one. Not sure if that is simply translation/difference between countries and infrastructure.

What some people here are interested in is the weight of each adapter. It's assumed that if a measurable difference is detected, the heavier adapter would have a higher current rating (since there appears to be a difference in specs between the two).

I agree they are almost certainly identical. It is odd that the electrical rating is so different - 250kW at 500V would imply at least a 500A capability, and in reality considering the cars are at more like 350v when pulling 250kW, you’re talking more along the order of 700A.

Apologies to all.. I just loaded up my scale with a set of (supposedly) calibrated weights. The scale is indicating an extra 4 grams at 820 so it looks like my adapter weighs 819 grams.
Good job. Thank you.
Short of side-by-side bench-top dissection, that is a strong indication that the two adapters are equivalent and quite possibly identical. The densest parts of the adapter should, of course, be made of metal--e.g., and fasteners and electrical contacts and transfer pieces. If conductive pieces were larger in the North American version, I'd like to think that it would show up as a noticeable weight difference.
Differences in labeling are puzzling, but not particularly worrisome, at this point. Explanatory speculations are offered here and by others.
