The L3 EV charging setup dumps 200-900 volt at up to 100 amps into the car. People charge their car in the rain.

I don't want an adapter that makes Big Clive say "oh, that's even better. That's very interesting."

The CCS spec allows for 500A and 1000V, so even more. Tesla gets around their 400V battery by using 620A+

The charging networks are "banning" them:

So if anything goes wrong, you're probably in a worse position from a liability/compensation standpoint.

Not the parent. You could be passing 150kW or more through an adapter. I think it’s a very bad idea to risk your life/car/safety on a non-approved adapter.

Might void your warranty and there’s no guarantee on quality for components. There’s a lot of juice flowing across it.
