    Product works as described, and I personally think it’s better than the one Tesla offers on their website. Gives an additional length of wire to play with in your set up as well as a sturdy plug so you know it’s firmly inserted into the receptacle.

    I lost my original Gen 1 adapter for my 2017 Tesla Model X and tried to order another but they were out of stock. So I found this NEMA 14-50 adapter and its worked great so far!
