JBL Charge 4 Not Charging Try These Fixes

Why is JBL Charge 4 Not Charging and How Do I Fix It?

JBL is a popular brand known for its high-quality Bluetooth speakers. The JBL Charge 4 is one of their most popular portable speakers, loved for its powerful sound, rugged design, and long 20-hour battery life. However, many JBL Charge 4 owners encounter problems with charging their speakers. If your JBL Charge 4 is not charging, don’t worry – this guide will walk you through several troubleshooting tips to fix the issue.

The most common reasons for JBL Charge 4 not charging are an incompatible or faulty charger/cable, a dirty charging port, a drained battery, software bugs, and hardware issues. By methodically trying different chargers, cleaning the ports, resetting the speaker, and checking the battery’s health, you can isolate and fix the underlying problem. Replacing defective parts may be necessary if the issue persists.

Key Takeaways

  • Use the original JBL USB-C cable and compatible 5V/2.3A USB charger to charge your JBL Charge 4. Incompatible third-party accessories can prevent charging.
  • Clean any debris in the charging port with compressed air. Pocket lint and dirt can block proper electrical contacts.
  • Try resetting the speaker to factory settings. This clears any software bugs that may disrupt charging.
  • If the battery no longer holds charge, replace it following the step-by-step battery replacement guide.

Incompatible or Faulty Charger/Cable

The most common reason a JBL Charge 4 won’t charge is because of an incompatible or faulty charger or USB cable.

The JBL Charge 4 requires a 5V/2.3A USB charger to function properly. Lower-powered chargers may not provide sufficient electrical current to charge the battery. High-powered chargers like laptops or Quick Charge bricks can also damage the charging circuit.

Be sure to use the original JBL USB-C cable as well. Third-party cables often have poor electrical contacts, preventing effective power transfer.

If you don’t have the JBL accessories, try using a compatible 5V/2A USB charger from another device like a tablet. Also, test different USB-C cables to isolate the fault.

Dirty Charging Port

Charging issues can also occur if the JBL Charge 4’s charging port contains debris or pocket lint buildup.

Carefully inspect the USB-C port for any visible debris. Use compressed air to spray out any dirt or lint trapped inside.

You can also gently clean with a toothpick or soft-bristle brush if compressed air doesn’t fully clear the port. Just be very careful not to damage the delicate pins inside the port.

Cleaning the charging port will allow for proper electrical contact so your speaker can charge correctly.

Software Bugs and Frozen Devices

The JBL Charge 4 contains an integrated software system that controls all its functions. Sometimes, software bugs and crashes can prevent the speaker from charging properly.

If you’ve ruled out hardware issues, try resetting the JBL Charge 4 speaker to factory default settings. Press and hold the Bluetooth and Volume Up buttons simultaneously until the speaker turns off. This resets the software, clearing any bugs.

Resetting can also “unfreeze” the system if the speaker is unresponsive when connecting the charger.

Faulty or Depleted Battery

As the JBL Charge 4 battery ages after years of use, it slowly loses the capacity to hold a full charge. An old battery that no longer retains charge is the most common hardware reason a JBL Charge 4 won’t charge.

Check the battery health by playing music – a faulty battery will only last for 1-2 minutes before automatically powering off even when fully charged.

If the battery is depleted, replace it by following iFixit’s JBL Charge 4 battery replacement guide. This involves opening up the speaker and swapping in a new battery.
