Using Joy-Con Controllers Wirelessly - Nintendo Switch Manual

Hold
The Joy-Con controllers will remain paired when you detach them from the console, and you'll
be able to use them wirelessly. If they run out of battery, attach them to the console when it's
charging to recharge them.
Can I detach the Joy-Con controllers and use them with another console?
Each Joy-Con can only be paired to one console at a time.
