JBL eXtreme 4 All lights blinking issue

Hey guys, I have a JBL eXtreme 4 with an issue.

All lights are blinking when I connect power.

Its at 50%, pairs normally, sound great. But cant charge.

I did a factory reset ( + and Play) didnt change anything.

Am usin official charger. Also does the same with other 60w chargers

Any clue ?!
