mine is about 1.5yrs old. Battery died and now wot charge. I plug it in and a single white light flashes but won't charge. Won't stay on long enough to rest.
No, I would not recommend this to a friend.

Please try to use a different cable or power adapter to charge your JBL Charge 4. We would also recommend trying to charge the unit overnight. If you need more help, please reach out to our Customer Support via chat or email. We're here to help. http://bit.ly/30JI2G4
