A great host always has a spare battery
Keep the party going twice as long by having a spare JBL Battery 400 on hand. Just insert it into the battery slot in the back of your JBL PartyBox Stage 320 when the first one loses its charge — each battery has enough power for up to 18 hours of playtime, so you could keep the party going for up to 36 hours. It can also replace the rechargeable battery inside a JBL Xtreme 4 when it starts to degrade.
Doubles as a powerbank
The charging case's USB-C port lets you top up your phone or tablet on the go, so the Battery 400 keeps more than just your speaker running.
