This worked perfectly for needing a bit of extra length to be able to plug into my family cabin's dryer outlet. The price is right and cord is not too bulky for 50ft. I just cut the neutral prong (not needed for car charging) to fit into the 4-prong 30amp dryer outlet and connected my Tesla nema 10-50 adapter to the female end, you have to dial down the amp draw in the car to 22 amps (80%) before charging as that's the max a 30 amp dryer outlet and this cord can or should provide for more than a few hours. Very happy with this purchase!
