I was offered a free nacs to CCS adapter to review on my youtube channel from an unknown company. While I love free stuff I could not in good faith accept it. I did not want to open the potential can of worms that would come with it.
Also the big 3 adapters are not that expensive in the grand scheme of things. Go back and look at the Chademo to CCS/Tesla adapters if you want to see how a real expensive adapter looks.
I would think the wires would immediately melt on the version in the right picture. I see some positive feedback after actual use on some of these economy adapters being sold on Amazon.
