JBL’s new PartyBox 720 doesn’t need to be plugged in to keep the party going

September 4, 2025

JBL has just launched PartyBox 720 to make your parties even more worthwhile. And unlike its 4-year-old predecessor, JBL PartyBox 710, this guy can even run on battery power alone! So in this article, we will explore everything the JBL PartyBox 720 brings, alongside its expected price in Nepal.

JBL PartyBox 720 Overview

Design

JBL hasn’t made many changes to the PartyBox 720. This thing is slightly larger than its predecessor, and also a bit heavier (31 kg > 27.8 kg). But of course, JBL has fitted in a handle and wheels for easy carry.

And it’s got that signature JBL lightshow up front that can sync to whatever you’re listening to as well. Whereas the PartyBox 720 is also IPX4 splash-resistant like before.

Sound

For the PartyBox 720, JBL went with slightly bigger bass drivers. So there are two 9-inch woofers here (compared to 8-inch woofers on the PartyBox 710) for better bass response. But at the same time, the PartyBox 720 has smaller tweeters (2x 1.25-inch < 2x 2.75-inch). With this setup, JBL says this speaker can deliver 800W of total power and cover 32 Hz – 20 kHz of frequency response.

Built-in battery!

Like I mentioned before, the PartyBox 720 has built-in batteries now. Making it the biggest battery-powered speaker JBL has ever made. And the company says the PartyBox 720’s massive 99.02 Wh battery can deliver up to 15 hours of playtime on a single charge.

A quick 10-minute top-up should be good enough for 2 more hours, while you’ll need to wait 3 hours for a complete refill for the PartyBox 720. But the good news is that JBL will also be selling backup batteries, so you can just swap out the dead one.

In terms of connectivity, it supports Bluetooth 5.4 with Auracast to connect to multiple PartyBox 720s at once. Other than this, it has USB-C, line-in, aux-in, and a couple of XLR inputs for microphones, guitars, or any other related setups.
