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!
