This battery fits my PartyBox Stage 320 perfectly, keeping the music going all day without issues. Performance is on par with the OEM model.The built-in USB port is a smart addition—I can charge it separately or on the go without needing to plug in the entire speaker. It snaps in securely, and on a full charge, it lasted over 15 hours of continuous play.My only gripe is the product listing, which shows two batteries in the first photo without clearly stating that it’s a 1-pack, not a 2-pack. I initially expected two and was surprised to find only one, but later realized the image was just showing the front and back of the battery.Even as a single unit, it’s a cost-effective and solid replacement to keep the speaker powered and the music flowing.

The Partybox 320 and Xtreme 4 can both use this battery and it is very handy to have if you are needing more battery life. The Runoower battery is nearly identical to the JBL brand, but the Runoower also has a USB port to allow it to be charged externally. Slipped it right into my Partybox 320! and it worked perfectly b

Tried this extra battery pack for my JBL stage 320. I simply replaced the factory battery with this one in the back of the unit and let it charge to full. I had it playing for 4+ hours at 50% volumne and still had reserve capacity. It has a usb-c port for external charging, which is very convenient!

I got this (and another) as back ups for my Xtreme 4 Speaker when camping and just for general use. I love having a extra battery and the investment was worth it. My battery that came with it died so I grabbed these. It works as well as OEM and I love the fact I can charge it while the other one is in my speaker! 5 Stars!

I’m very happy with how well this battery works. It has allowed my JBL 320 to play throughout the day. If I do need a battery, it has a quick charger feature which is great. Definitely a quality battery.

A replacement battery for the jbl party box. Never thought I would have to replace it but here we are. Works like the original but not sure about longevity.

The standby battery provides a stable operational state for my speaker. No interruptions in my music party!
