Has anyone tried this 14-50 extension cord?

Little resistors, eh? This is sort of like USB charging hell. And other cute remedies to half-baked designs. Or plugs that you can force in upside down (goodbye phone USB port, Firewire PC ports, etc). Or the classic $0.89 "ground lifter" technology. It seems that it took more time for mankind to invent the reversible USB C plug than it took dinosaurs to go extinct.
It's hard to follow the narrative format. Please, please, is there a chart showing how all these adapters and sockets are wired, little resistors and all ? We should be able to create, at low cost, some universal adapters.
They really take Tessler owners to the cleaners on all the Tesla-oriented EV cords and plugs. As far as the OP's cord is concerned, a #6 cable is pretty massive, it looks good.
In the meantime, most, no strike that, many, no strike that too, some Tesla owners probably take enough interest in the details that they can be counted on to set their charging current correctly, even if it has to be done manually. But of course perfect interlock is ideal, especially if - against all advice and common sense - you loan your Tesla to foolish friends, or housemates.

LOL. Actually the Tesla UMC is pretty well designed and far more flexible than what other EV vendors are providing. As long as you use the Tesla UMC adapters plugged into their intended receptacles, you (or your friends or housemates) are ok.
Here in North America, Tesla offers eight UMC adapters - two at each current (amperage) level. They are:
15 amp (12 continuous) - 5-15 (120V) and 6-15 (240V)
20 amp (16 continuous) - 5-20 (120V) and 6-20 (240V)
30 amp (24 continuous) - 10-30 and 14-30 (both are 120/240V, but only the 240V portion is used)
50 amp (32 continuous) - 6-50 (240V) and 14-50 (again 120/240V, but only the 240V portion is used)
Each of the UMC adapters has a little resistor built into the portion that plugs into the UMC that indicates one of those four current levels. The plugs on the adapters also have thermal sensors to detect an overheat condition - so the UMC can tell the in-car charger to back down the current a bit to cool things down. The nice thing about the evseadapters UMC adapters is that they plug into the UMC exactly as the Tesla UMC adapters do, set the max current level correctly, and have the thermal sensors.
Beyond that, the UMC simply can't figure out what the user might be doing with things like extension cords, home made 'cheater' adapters for other receptacle types, and so on.
I bought this one, just in case. Conntek 15306 50 Amp RV Extension... https://www.amazon.com/dp/B00F17QD9O

Here's the TT-30P to 14-30R adapter:
This should work correctly with my mobile connector and 14-30 plug; 24A charge rate. I'll know as soon as I stop in an RV park and try to charge....
