This battery fits my PartyBox Stage 320 like the original, swaps in fast, keeps the music thumping all night. USB-C charging means I can power it up while the others running, and the LED lights (green charging, red full) cut out the guesswork other spares leave.It matches the OEMs runtime, handles outdoor gigs with no problem. For the price, it's a good value. Comes with just a USB cable, so grab a beefy USB charger or it will crawl to full.

If you need a spare battery for your Partybox 320 or Xtreme 4 and want to save some $$, this is a solid option. I like the original battery, this aftermarket battery also has a usb-c charging port on it, so you can charge it externally without having it in the speaker. A great way to keep the party going when your battery runs out.

Snagged this extra battery pack for my JBL stage 320, wasn't sure what to expect since it's a smaller capacity than OEM, but I popped it in and let it charge using the factory cirtcuitry and tried it after full charge. I had ot going for 4+ hours at 50% volumne and still had reserve capacity, so for me, this is a win. I love the fact that you can charge it via USB and that it fast charges using usb-c.

Great spare for jbl partybox 320 ran it at 50 with deep bass for 4 hours and still had plenty of battery life left, while it may be short of oem battery life at this price point it's great to have if your out with out a ac outlet to plug in your 320 would recommend it. Easy pull out table makes swapping a breeze.

FINAL UPDATE: company contacted their manufacturers and found out that the battery indicator will be green when charging and red when fully charged. So now I will change my review to 5 stars. Great customer service!UPDATE: So the company reached out and sent me a replacement battery. This company is cery responsive and was quick to send me a new one. Unfortunately the new battery does the same thing where I can never get a red charging light. Maybe just a design flaw. Aside from only having a green full light at all times, the batteries work fine. Just strange that they advertise a "red" light when charging via Type C and a "green" light when full. Maybe they should check their inventory and have a faulty batch. I will still give 4 Stars for superior customer service.Update: seems my battery is defective. When I try charging with with a usb c cable, the charging light is always green even when the battery is dead. So it is very inaccurate and also quite concerning that it is even charging safely. I've never got it to show the red light for charging. I've tried many different cables and charging blocks always getting the same result.This battery option fixes what the original is lacking. You can now charge this battery from the speaker or outside of the speak using USB C. This only makes total sense and not sure why the original battery didn't have this option. I bought a second original back up battery before they made these with the USB C charging. Wish I could return that one, but it's too late. Guess I have 3 batteries now. Lol.This one is a must have!

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