Why Is My JBL Charge 4 Not Charging ? 5 Easy Troubleshoot

Sometimes you may ask yourself why is my JBL Charge 4 not charging. As you probably already know, nothing occurs when you plug it in. Even worse, the battery indicator light is flashing red, yet the device still won’t charge. Also, it ruins your mood when you want to jam into your top pick music—even if it’s only for a minute.

Many people who have the JBL Charge 4 have had the same problem. As a result, I figured I’d pass along some wisdom and advice that have served me well.

If your JBL Charge 4 is having charging problems Audiosk will explain why and offer some simple options to fix the problem.

Why is my JBL Charge 4 Not Charging ? (Common Reasons)

Your JBL Charge 4 needs an AC adapter with a power rating of 5V/2.3A. If you use a charger with a lower rating, it won’t recharge your speaker. Also, check for a defective AC or car circuit, a tripped breaker, a blown fuse, faulty wiring, or even a general power failure.

I learned this the hard way when I tried using a phone charger, and it just didn’t work.

Sometimes the problem is as simple as a loose connection. Make sure the charger is firmly plugged into your speaker and the power outlet. A slight wiggle to ensure a snug fit can sometimes make all the difference.

Check if the wall socket you’re using is working. Plug in another device to see if it gets power. I once spent hours troubleshooting my speaker, only to find out the socket was the issue!

Dirt and debris in the charging port can prevent your speaker from charging. Use a small, soft brush to gently clean out any dirt. Remember, be gentle to avoid any damage.

Batteries change over time, and the charging current they draw changes too. An aging battery might not charge efficiently or at all. If your speaker is old, this could be the issue.

The operating system on your speaker might freeze or develop bugs, leading to charging problems. Sometimes, a simple reset can fix these issues.

In the realm of portable speakers, understanding battery life is crucial, particularly when addressing issues like “JBL Charge 4 keep turning off.” If your JBL Charge 4 keeps turning off, it might indicate a battery-related issue. It’s essential to ensure the Charge 4 is fully charged and the battery is in good health.

Battery issues can lead to unexpected shutdowns, and while the Go 3’s battery life is robust for its class, the Charge 4 should also provide several hours of playtime when properly charged and maintained. Regular charging and careful usage can help prevent power issues and prolong the life of your speaker’s battery.

How to fix my JBL Charge 4 Not Charging ? ( 5 Quick Fixes)

It’s helpful for you to know how to fix your JBL Charge 4 when it’s not charging. Here are 5 quick guides we’ll suggest for you:

1. Replace the defective charger

Initially, I was clueless about what was wrong. Then, it hit me – maybe the problem was with the charger. I needed to know if my suspicion was right. So, I took the charger and tried it on another device with the same port. To my dismay, that device didn’t charge either. That’s when I knew for sure – the charger was the issue.

Knowing that the JBL Charge 4 needs a specific type of charger (an AC adapter with a power rating of 5V/2.3A), I went on a hunt for the right replacement. Having a charger that met these specific demands was essential in order to keep away from any more troubles.

I plugged the new charger to my JBL Charge 4 after receiving it. It began charging, which was such a relief! It was such a quick fix, and the problem was gone.

2. Reset the speaker 

I must admit that I had my doubts when I first attempted this with my JBL Charge 4. My speaker began charging once again, much to my surprise, after the reset: 

The first thing you need to do is power on your JBL Charge 4. This may seem to be obvious, but it’s very crucial for the reset to function well.

The real magic takes place here. Hold down the Volume Up (+) button along with to the Bluetooth button together. For a few seconds, you must hold the pressure on these buttons.

Press and hold the buttons until the speaker powers off by itself. When this happens, it means the hard reset is about to begin. Please be patient, as it may take a little bit.

Pressing the power button will turn the speaker back on after it has switched off. The reset process is finished with this step.

Now, try charging your speaker again. Plug in the charger and see if it’s working.

3. Keep Firmware Updated

Another key step is ensuring your speaker’s firmware is up to date. The JBL Portable app, available for both iOS and Android, is your go-to resource for this. It’s easy to use:

  • Download and install the JBL Portable app on your smartphone.
  • Connect your JBL Charge 4 to the app.
  • The app will automatically inform you if there are any firmware updates available.

If an update is available, follow the app’s instructions to download and install it.

4. Try a Different Wall & USB Charger

As I found out, the problem with your JBL Charge 4 not charging might be the wall and USB charger. Let me show you how I figured it out:

  • Checking the Wall Charger’s Power: Your JBL Charge 4 needs a 5V/1.0A charger. I used a weaker one at first and it barely charged. Too strong a charger, over 5V/1.0A, can harm your speaker. Stick to the right power output to keep your speaker safe and charging well.
  • Testing the USB Cable It could be the USB cable too. Try charging another device with it. If it works, your cable’s fine. I used my speaker’s cable for my phone and saw it didn’t charge. That’s how I knew the cable was bad.

I learned it’s all about using the right charger and cable. If your JBL Charge 4 isn’t charging, check these first. It worked for me and it’s a simple fix!

5. Clean the Charging Port

Even though the JBL Charge 4 is water-resistant, I found out that dust and dirt could still sneak into the charging port. This gunk can stop the charger from connecting properly.

Even though the JBL Charge 4 is water-resistant

I used a small, soft brush – something like a paintbrush works great. A toothpick can help too, but you have to be extra careful not to poke too hard.

After a gentle clean, I shone a flashlight into the port. This helped me spot a stubborn piece of lint that was hiding in there.

Once the port looked clean, I plugged in my charger. To my relief, my JBL Charge 4 started charging right away!
