Not related to your point at all, but: The switch uses USB-C. Pretty much any USB-C charger will work. For the dock you do want to make sure it can push enough power, but it’s a rather low requirement. I use the same charger for my SteamDeck dock and the Switch dock. It’s the great thing about USB-C. But of course gamestop would try to sell you their generic crap instead of an official one.
