Keep an eye on the indicator light at the front lower portion of your speaker. A blinking red light signals a low battery. So, promptly plug it into a power source. When charging, this light should turn white. If it stays red, your speaker isn’t charging.

Why is your JBL Charge 4 not Charging, and how to fix it?

Faulty Power Source:

Surprisingly, the real culprit might be right under your nose – the power outlet. Yes, it’s not always the speaker at fault. If your JBL Charge 4 isn’t charging, consider a damaged, faulty, or dead power outlet as a potential reason.

Faulty Power Source

Fix: Resolving this issue is a breeze – no toolkit required! Simply switch to a different power source and see if your speaker begins to charge. You can also test the original outlet with other devices or use a voltmeter or voltage tester to check its status. If the problem persists, it’s time to consider other possibilities.

Charging Cable to Blame:

Got a working power outlet? Great! Next suspect: the charging cable or adapter. Tangled wires can lead to wear and tear, possibly damaging them and affecting the charge. Give your charging cable and adapter a thorough check for any damage.

Fix: Rest assured, this is a fixable issue! Simply replace the charging cable and reconnect it to the power source to test. If that doesn’t work, try swapping out the adapter with a similar one. This should likely solve the problem, but if not, there’s another step to try

Depleted or Damaged Battery:

If the first two solutions didn’t do the trick, let’s consider another angle. Have you been using your Charge 4 for extended periods, or while it’s charging? This could be the root of the problem. Continuous use, especially during charging, may deplete the battery, leading to charging issues.

Depleted or Damaged Battery

Fix: While not as straightforward as changing power outlets or cables, replacing the battery isn’t too complex. Swap out the old battery for a new one and then try charging your speaker. If this doesn’t fix the issue, it’s time to move on to the next troubleshooting step.

Dirt and Debris can obstruct charging:

Living in a construction or industrial area means your speaker might get exposed to dust and debris. This can clog the charging port, potentially disrupting the charging process.

Sneaky Software Bug:

Software bugs and viruses can be really sneaky damaging everything that comes in its way. So, if your speaker isn’t charging it might be because of some problem in the settings or a software bug
