What? This conversation is about adapters for a CCS car to charge at a Supercharger, if your car is CCS you don't need a J1772 adapter, it's already what you have on your charge port.
If you mean the adapter locks like a CCS plug I think the problem is that the adapter is unpowered. This is why the MagicDock adapter locks to the Supercharger plug while it's still in the Dock. It needs power to activate the locking mechanism. I know I just said some genius would figure it out, but saying that it locks like a Tesla adapter locks is wrong. Teslas have the locking tab on the car, CCS plugs have them on the plug. So where will an adapter latch between the lockless CCS charge port and the lockless Supercharger plug?
