JBL PartyBox 720 – Loudest Battery-Powered Party Speaker

We bring peak party energy wherever we go with the JBL PartyBox 720. Superior JBL Pro Sound, deep precise bass that hits just right, and a lightshow that goes all in—starry lights, flowing trails, and pulsing strobes. It may be big, but it’s built to roll, with a comfy handle, smooth wide wheels, and a splashproof design that can handle a little poolside action. The swappable batteries (sold separately) gives us up to 15 hours of playtime—perfect for off-the-grid parties. Still going strong? Swap in a fresh battery and keep the music alive. We can stereo pair two 720s or wirelessly link up multiple JBL Auracast™-enabled speakers for even more sound. And whether we’re streaming, singing karaoke, or plugging in mics and gear, the USB port and dual XLR inputs have us covered.
