I'm hoping to get some validation for the scenario I'll be in over the next couple of weeks. I'm visiting my parents house and they have a 10-30 outlet for their dryer I intend to use. I purchased the 10-30 official Tesla adapter from shop.tesla.com. My concern is that 20' may not be enough to reach, so I was thinking about buying a 20' extension cord. I realize 10-30 isn't very common compared to 14-30 or 14-50, so I'd like to buy one of those 14-x cords and use a 10-30 adapter for this one-off. Would I be able to purchase one like this (Amazon product) and simply buy a couple of 10-30 to 14-50 adapters like this (Amazon product) to stay "compliant" ? Thank you!

No real reason that it wouldn’t work. If you can minimize adapters, that could be beneficial, though 14-30 is probably a lot more common. Ultimately, any of those extension cords are just passing the two hots and ground wires. They shouldn’t be altering the current going across at all.

You are the "poster child" use case for this extension cord:

https://www.evseadapters.com/products/heavy-duty-nema-14-50-extension-cord-for-tesla-20-ft

It has no neutral conductor (makes it lighter and the UMC does not use it) and it has the neutral pin omitted from the male end. This allows it to be plugged into a 14-30 or a 14-50. Very handy!

Then also get this:

https://www.evseadapters.com/collections/adapters-for-tesla/products/nema-10-30p-to-14-50r-adapter

That will let you plug into your parents 10-30 with that extension cord (or direct from your UMC if you don't need the cord).

I also bought this so I could use that extension cord on a NEMA 5-15 and 5-20 as well. Kills many birds with one stone. I somewhat regret buying *all* the UMC adapters since this solution is more versatile (though not as many safety features with this setup as with just using the Tesla factory adapters).
