6 Common Causes Why a JBL Speaker Won’t Charge and How to Troubleshoot Them

Here are some common issues that you may encounter when charging your JBL speaker and how to troubleshoot them:

1. Faulty Wall Power Outlet

Before you start troubleshooting the hardware and software components of your speaker, you should first confirm if your wall outlets are working fine. Sometimes the voltage from your wall outlets may be low or dangerously high, which may cause your JBL speaker to fail to charge.

The first thing you should try is plugging your JBL speaker into another wall outlet and see if the problem persists. If the speaker charges successfully, then the issue is with the other wall outlet.

A more lasting solution is using a surge protector. Such a device can help protect your JBL speaker from voltage spikes that may damage the battery or charging components.

2. Faulty Charging Cable

A faulty micro-USB charging cable is another prime suspect why your JBL speaker won’t charge all of a sudden. Here are some of the things you can do in such a case:

  1. Check the Cable for Damage

Examine the charging cable for any signs of physical damage, such as frayed wires or a bent connector. You may need to replace your USB cable if you see obvious signs of damage. 

  1. Test with a Different Cable

If you have access to another micro-USB charging cable, try using it to charge your JBL speaker. If the speaker charges successfully, then the original cable is likely faulty.

3. Broken Charging Port

If there is debris or dust in the charging port of your JBL speaker, it may prevent the cable from adequately fitting into the USB port. Forcing it in may result in the bending of the connector pins. In the event of water damage, a hairdryer may be used to dry the excessive moisture.

To further examine your charging port for any signs of damage:

  1. Inspect the charging port for any visible damage or debris. If there are, gently clean the charging port using a soft-bristled brush or a can of compressed air. Avoid using sharp objects that may scratch or damage the charging port.

  1. Follow the instructions provided in the repair kit carefully. Depending on your JBL speaker model, you may need to remove the back cover, the battery, and other components to access the charging port.

4. Circuitry Issues

If the speaker still won’t charge after replacing the charging cable and checking for a broken charging port, it is likely that the circuit is damaged and needs to be checked by a professional.

  1. Check for Warranty

Before taking your speaker to a service center, checking if it’s still under warranty is a good idea. If it is, contact JBL customer support to initiate a warranty claim. They will advise you on how to proceed with the repair process, which may involve sending the speaker in for repairs or exchanging it for a new one.

  1. See a Certified Repair Technician

If your speaker is no longer under warranty, you can take it to a certified repair technician. Look for a reputable repair shop that specializes in repairing JBL speakers and has experience working with the model of your speaker. The technician will assess the circuitry issue and provide you with a quote for the repairs needed.

5. Outdated JBL software

If all the aforementioned possible causes check out or all troubleshooting methods didn’t work, then you should consider software issues. Bugs in the code can interfere with the charging capabilities of your JBL speaker. Ensure that you are using the latest software on your speaker, and reset it if necessary.

If you suspect that outdated JBL software is causing your speaker to not charge, you can take the following steps:

  1. Check for Updates

Check the JBL website to see if there are any available software updates for your specific model. Download and install the latest software to your JBL speaker.

  1. Reset the Speaker

To reset your JBL speaker, hold down the Bluetooth and volume buttons for about 5 seconds. This will work on JBL Go and JBL Flip 5. To reset your JBL Charge, press and hold the play, pause, and volume up buttons together until the power button glows.

  1. Contact Customer Support

If the above steps do not work, you can reach out to JBL customer support for further assistance. They may provide additional troubleshooting steps or recommend sending the speaker for repair.

6. Damaged Battery

One of the most likely reasons why your JBL speaker won’t charge is a damaged battery. While lithium-ion batteries are designed to undergo hundreds of charges, their recharging capacity diminishes with time.

Confirm if the battery is in fact the issue. If it is, here are steps you can take to replace it:

  1. Find and buy the battery replacement kit that matches your JBL speaker’s model. Popular varieties like JBL GO2, JBL Flip5, and JBL Boombox 2 come with battery replacement kits that contain everything you need. They may also come with a video tutorial on how to service the speaker.

  1. After replacing the battery, connect the charging cable and confirm if the JBL speaker is charging.

Note: Remember to dispose of the old battery in accordance with the guidelines in your local area.

If you are not confident in replacing the battery yourself, you can always seek assistance from a certified repair technician or JBL customer support. They can guide you through the process or perform the replacement for you.
