JBL partybox 100, it fully charges so the battery is working but the speaker is temperamental when turning on, sometimes it wont turn on, But when it does decide to turn on the bass is heavy and the volume is loud so once you get it on it works as expected grab a bargain if you have the know how to change the control module which will completely fix the issue, I have been using it for the past 4 weeks since it started playing up and its the odd time it wont turn on from the first press but takes multiple presses to turn it on,
