A:Answer No, you don't. The Switch comes with two (2) Joy Con controllers that charge when attached to the Switch console, while the console is in the charging dock. The Switch also comes with a non-powered grip you can attach the Joy Cons to - looks just like this one, except it doesn't have power. It just lets you use the two Joy Cons as a single controller. The charging grip just lets you charge the Joy Cons without having them be attached to the Switch console, and you can even have them charging with the cord while you're using them as a single controller. Also handy to charge additional Joy Cons simultaneously (if you have more than two).
