Nintendo Joy-Con AA Battery Pack Pair

The Joy-Con battery life will already see each controller last you for 20 hours, but for those worried about them running out midway through a play session Nintendo has looked to help you keep them charged for even longer.

The Joy-Con AA Battery Pack is their answer, which, as with the Joy-Con Strap, slides down the rail on a Joy-Con controller, and will extend the battery life by supplementing it with extra juice from AA batteries that have been inserted.
