Joy-Con AA Battery Pack (R)

Description

The Joy‑Con AA Battery Pack (R) is a battery pack that clip onto the side of a Joy‑Con (R), connecting through the same rail used to attach it to the console or grip. Once attached, the pack trickle‑charge the Joy‑Con’s internal battery while you play, letting you go much longer between dock or grip charges. Nintendo includes alkaline AA batteries in the box, and you can also use rechargeable NiMH AAs. The pack add a bit of bulk and weight, which some players find improves comfort when using the Joy‑Con separately, as they feel more like a traditional controller grip.

The pack is especially handy for long multiplayer sessions or travel, since you can swap in fresh AAs instantly instead of waiting for a recharge. The LED on the pack lights up while charging and turns off when the Joy‑Con is full or the batteries are depleted. Given the sometimes poor state of Joy-Con charging I always found these useful and definitely more comfortable. Try not to use disposable AA batteries though!
