I have 2 pairs of JoyCon and Pro controllers that charge with it. Works like a charm and has no issues. I would probably prefer the green light not to be active unless a fully charged device is connected. It glows red when connected to a charged device, green when the device is charging, and green when nothing is connected. The last change is the only change I would make (no light when nothing is plugged in). This is a minor element, however, but important if you don't want the room to glow green when nothing's charging. I've also plugged it into the Switch Dock, so no additional power adapters are needed as there's enough power going through it. Good price and quite durable
