You spoke. We listened. THE BATTERY's improved performance and new features have been designed from community feedback. We've dropped the recharge time to 2 hours using a 65W charger such as THE CHARGER, made it possible to charge whilst playing your SOUNDBOKS at 11, and designed it to double up as a powerbank.

View full details

    You better believe it. You can now charge your SOUNDBOKS while turning up your tunes to 11. All you need is THE CHARGER or a 65W+ USB-C PD power supply.


    This ain't no one trick pony. Not only does it power your SOUNDBOKS, but it can charge your tech too. Just plug your USB-C cable in and get some much needed juice.


    2 hours is all it takes to recharge this back up to full battery. You could also watch The Ridiculous 6 (0% on Rotten Tomatoes) or clean your apartment in that time, but neither of those are that great.

Can I play my SOUNDBOKS while charging with THE BATTERY? You bet you can. This requires the official SOUNDBOKS charger or a 65W USB-C PD compliant power supply.

Can I charge my phone or other USB-C compatible devices while playing music? Yes, of course you can.

How does battery swapping work?With an ingenious clip system developed with our original design. THE BATTERY fits snuggly in the port, cable out and the barrel-style battery jack slides into the battery for a connection that can take some heavy stress.

Is the old charger compatible with THE BATTERY? No, the old charger is not compatible with THE BATTERY.

Does THE BATTERY work with all existing SOUNDBOKS speakers? All of 'em except the SOUNDBOKS 1.

How long does it take to fully charge THE BATTERY? It takes 2 hours to fully charge THE BATTERY using THE CHARGER (our official charger).

Can I use any charger that fits to charge THE BATTERY? For sure, but it might take a bit longer. Depending on the wattage, it can take up to 18 hours to fully charge THE BATTERY. Ours only takes 2 hours.

Why doesn't THE BATTERY come with a charger? In short, this will help reduce electronic waste and encourage people to use their existing USB-C chargers. That's definitely a good thing, if you ask us.

How much of THE BATTERY is used to fully charge a phone? About 20% of its capacity.

How long does THE BATTERY last?This hasn't changed from previous designs. It'll last 40 hours at mid-volume with any SOUNDBOKS. When you turn up to 11, it gives you 6 hours for the SOUNDBOKS 4 and 10 hours for the SOUNDBOKS Go.

Which speakers will be shipped with THE BATTERY? From June 19th, all new SOUNDBOKS speakers will be shipped with THE BATTERY.
