Thank you for bringing this to our attention. We suggest charging the device for at least 8 hrs. If the issue still persists, We'd like to work with you directly to address the power issues you're experiencing with your JBL Partybox 310. If needed, we'd also like to get more information so we can check your options. Please contact our customer support via our official website or toll free number.
Sorry, there was a problem. Please try again later.It is most likely something inside of the speaker. If you got the protection plan take it to best buy and work though them, if not try to take it to a repair shop and see if its cheaper to get a new one or have them do work with either the wiring or replace the battery.
