Don't go onto Amazon and order a random cheap ac adapter for any console that you have. They create a bunch of noise on the screen and it leaves a trail of flickering pixels going up the screen.
The catch here is that not all USB-C bricks actually support all the potential voltages. And the Standard allows for supporting a subset of the standard voltages. Usually they downgrade, so asking for say 9v could give you 5v, which at least helps keep the magic smoke in.
