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

Dealing with a JBL Charge 4 speaker that won’t charge or turn on can be frustrating, especially if it is still new. Fortunately, you don’t have to worry. These proven fixes can restore your speaker’s normal charge cycle.

Damaged or Incompatible Charger

If your JBL Charge 4 is not charging, start with the basics. Your charger could be the problem. This speaker uses an AC adapter with a power rating of 5V/2.3A. Anything less than that won’t recharge your speaker.

First, check if the charger works by trying it on another device. If the charger functions, confirm the power rating to ensure it supplies enough current to your speaker. A damaged charger typically has a burning or acrid smell and won’t transmit current to connected devices. Replace the defective charger and try to charge your speaker again.

Incorrect or Defective Charging Cable

The JBL Charge 4 speaker uses a USB Type-C cable for charging. Your speaker won’t charge if you plug in an incorrect charging cord. Then again, doing so might damage the charging port since they are incompatible. Check the cable to confirm that it is the correct one before connecting it to your speaker’s charging port. 

Also, inspect the charging cable for bends and cuts. If you notice visible damage, swap it immediately. The best option is to use the supplied accessories to charge your speaker.

Loose Connection

Sometimes your JBL Charge 4 speaker might not charge because of a loose connection. 

Inspect your connections on the speaker’s charging port and the AC adapter to confirm they are firmly in place. Disconnect and reconnect the speaker afresh to ensure they are secure, then try again to charge the speaker. If this doesn’t work, move to the next step.

Malfunctioning Wall Socket

You might not notice it initially, but the incoming power supply could be the issue. Even though most wall sockets last for over 15 years, they are not exempt from damage. Your wall outlet could be faulty and not transfer enough power to charge your JBL Charge 4.

Sparks, cracks, discoloration, and burning odors are all signs of a malfunctioning wall socket. You can test the wall outlet by plugging in a different device to see if it works. If not, try another socket and check if your speaker is charging. If you only have one outlet available, you may have to replace it with a functioning one.

Dirty Charging Port

Since the JBL Charge 4 is a portable waterproof speaker, you can go with it anywhere. You can use it for picnics, outdoor parties, and backyard barbecues. 

The downside of using your JBL speaker outdoors is that it will be vulnerable to dirt, dust, grass, and debris. These elements can clog the charging port, preventing connections between the charger and speaker.

Inspect the charging port for sediment buildup and remove any elements blocking the charger from coming into contact with the connector pins. You can remove the dirt buildup using a sharp object such as a toothpick or needle. Alternatively, a blower can help dispel dust and other tiny particles from the charging port.

Check the charging port pins for bends and straighten them using a tweezer if you find any impairments. If the port has irreversible damage, visit a service center to have it replaced.

Wet Charging Port

The JBL Charge 4 is renowned for its waterproof design. You can take it to the pool or the beach without getting anxious over spills. You can submerge your speaker in water, but it won’t get damaged.

Even though the JBL Charge 4 is waterproof, you cannot charge it when wet. JBL recommends drying the charging port first before plugging in power for charging. The chemicals in water can corrode the charging port causing irreversible damage.

Place the speaker with the charging port facing down to drain excess water and leave it to dry naturally for 24 hours. Also, wipe the charging cable with a soft, absorbent fabric and leave it to dry for about an hour before using it again.

Faulty Battery

One of the main culprits of JBL Charge 4 not charging is a faulty battery. A defective or dead battery can cause your JBL Charge 4 not to recharge. If your speaker is a few years old and you notice that the battery can no longer hold a charge, it is high time you replaced it.

Like most JBL speakers, the JBL Charge 4 uses a high-capacity Lithium-ion battery. Even though these batteries are renowned for their power retention, they cannot survive over 500 charge cycles without requiring a replacement.

If the battery is faulty, the only solution is to replace it. Fortunately, the battery in your JBL Charge 4 is replaceable. The best part is that you can do it yourself without taking it to a service center. But if you have issues replacing the battery, seek professional assistance.

Warning: Since you can’t buy the original battery from JBL, you can only get a third-party battery, which is a risky move. They don’t always work as they should.
