If you are able to get a charge by holding the plug to the outlet, I would say that the issue is how your plug is sitting in the outlet. I find that many times my charger does not sit in the outlet well, it kind of hangs/leans down. Its as if the holes in the outlet are oversized. By holding the charger into the outlet, it begins to charge. Poor design of the outlet, but not a function of a Type-C charger. This happens to me on a non-Type-C android charger.
