How To Fix: JBL Charge 4 Not Charging

Dealing with a JBL charge 4 speaker that won’t charge or turn on can be quite frustrating, especially if it’s new.

Fortunately, you don’t have to worry too much. There are some proven fixes that can help restore your device to its normal charge cycle.

Damaged or Incompatible Charger

When your JBL Charge 4 is not charging, it’s crucial to first consider if the issue is due to a damaged or incompatible charger.

A simple way to check is by using the charger with another device to see if it functions correctly.

This will help confirm if the charger has the appropriate power rating and supplies the necessary current to your speaker.

If you detect a burning smell or an acrid smell, it’s a clear sign that the charger is damaged and won’t transmit current to connected devices.

In such cases, promptly replace the defective charger to safely charge your speaker again.

Incorrect Or Defective Charging Cable

A common reason your JBL Charge 4 speaker won’t charge could be due to an incorrect or defective charging cord. When you plug in the USB Type-C cable and find no charging happening,

It’s crucial to check if the cable is the correct one for connecting to your speaker’s charging port.

Inspect the cable for any bends, cuts, or visible damage. If found, swap it immediately with the best option – the supplied accessories that came with your speaker to ensure proper charging.

Loose Connection

Sometimes, the issue with your JBL Charge 4 speaker not charging could stem from a loose connection.

Take a moment to inspect the connections at the speaker’s charging port and the AC adapter.

  • Confirm that everything is firmly in place. If not, disconnect and reconnect afresh to ensure a secure connection. Then, try again to charge.

If it doesn’t work, it’s time to move to the next step.

Malfunctioning Wall Socket

A malfunctioning wall socket is often an overlooked cause when your JBL Charge 4 is not charging.

You might not notice initially, but the incoming power supply from wall sockets that have lasted over 15 years are not exempt from damage.

A wall outlet could be faulty and not transfer enough power to charge your device. Look for sparks, cracks, discoloration, or burning odors as signs of a malfunctioning socket.

  • Test it by plugging in a different device. If it works, try another socket and check if your speaker starts charging.

If only one outlet is available, it might need to be replaced to ensure it’s functioning properly.

Dirty Charging Port

Your JBL Charge 4 is a portable waterproof speaker ideal for picnics, outdoor parties, and backyard barbecues.

  • However, the downside of being outdoors is being vulnerable to dirt, dust, grass, and debris that can clog the charging port, preventing connections between the charger and the speaker.

  • Inspect for sediment buildup and remove any elements blocking the charger from making contact with the connector pins.

  • Use a toothpick, needle, or blower to dispel tiny particles. Also, check the charging port pins for bends and straighten them with a tweezer.

Be careful, as any impairments can cause irreversible damage. If you can’t fix it, it’s best to visit a service center to have it replaced.

Wet Charging Port

The JBL Charge 4’s renowned waterproof design makes it great for the pool, beach, and accidental spills.

To dry, place your speaker facing down to drain excess water and let it dry naturally for 24 hours.

Also, wipe the charging cable with a soft, absorbent fabric and let it dry for an hour before using again.

Faulty Battery

A faulty battery can be one of the main culprits when your JBL Charge 4 refuses to charge.

Over time, this Lithium-ion battery, renowned for its high-capacity and power retention, may no longer hold a charge, especially if your speaker is a few years old and has gone through over 500 charge cycles.

When you notice that it can no longer recharge, it’s a cause for concern.

The best part is that the battery in the JBL Charge 4 is replaceable, making it a do-it-yourself solution.

You don’t have to rush to a service center unless you encounter issues while replacing it.

By taking matters into your own hands and replacing the defective or dead battery, you can revive your speaker and enjoy its impressive sound quality once again.

When your JBL Charge 4 encounters charging problems, it might not always be a faulty battery; sometimes, the issue can be traced back to software bugs within the speaker’s operating system (OS).

These bugs can cause the smart speaker to freeze or develop other unusual behaviors.
