Keep the music going longer with the JBL Battery 400—an official spare battery designed exclusively for the JBL PartyBox Stage 320 and JBL Xtreme 4 Bluetooth speakers. When your speaker’s battery runs low, simply pop in a fresh Battery 400 in seconds and enjoy up to 18 hours of extended playtime. With a second battery on hand, you can double that time to an incredible 36 hours of non-stop audio entertainment.
This high-capacity lithium-ion battery supports fast charging—just 10 minutes gives you an extra 2 hours of power, so your party never has to hit pause. Trusted JBL quality ensures compatibility and performance that matches your speaker’s original power source. Use the JBL PartyBox app to monitor the State of Charge (SOC) and know exactly when it’s time to swap out your battery.
Perfect for parties, road trips, or everyday use, the JBL Battery 400 is the reliable backup power you need to stay unplugged longer. Packaged in eco-conscious FSC-certified materials and printed with soy ink, it’s a smarter choice for the environment too. Only compatible with the JBL PartyBox Stage 320 and JBL Xtreme 4.
