It's a good thing we don't need adapters to put energy in our gas or diesel tanks. Nothing worse than having proprietary plugs and receptacles to achieve the goal of charging batteries. Similar to all the different versions of plugs for electronic gadgets.

Good morning Fisherman. You may have misunderstood. These are all standard AC receptacles in a campground. It just allows the vehicle owner to plug into various common outlets on the AC side. None of those receptacles are proprietary.

Hope that helps.
