Tried different charges, but my JBL Charger 5 is not taking any charge! It’s only three months old!

Hi, The speaker has a 12 month manufacturer’s warranty. Given that it is only 3 months old and that you have tried different compatible chargers and the speaker is still not charging, contact the JBL customer service centre in your location and make a claim for a manufacturer’s warranty repair, replacement or refund. (see the documentation that came with the speaker to find details about a warranty repair). Here’s the JBL warranty statement that may help if you can’t find the information Do not attempt to open the speaker to find out what is wrong as doing this will void the warranty.

Had same problem and changing the charging Ic solved it

but that was after diagnosis and finding it was the cause for it not charging
