When my grandson visits next month, he's planning on bringing his Nintendo Switch with him but didn't want to bring the dock for charging it. Looking on Amazon, I think I only need to buy a Type C to Type A cable with a plug-in wall charger, but they have both a 45W and a 65W. Assuming this is all I need for him to charge his Switch and controllers, should I go for the 45W or the 65W (and I'm assuming both the Switch and the controllers would charge together)? I don't own any consoles myself so just want to be sure I'm buying the right thing.
