How to troubleshoot a PD USB charger that is not working?

Hey there! As a PD USB charger supplier, I've seen my fair share of chargers acting up. It's seriously annoying when your charger decides to take a break, right? But don't worry, I'm here to walk you through how to troubleshoot a PD USB charger that's not working.

Check the Basics First

Let's start with the simplest stuff. Sometimes, the problem is super easy to fix. First, take a look at the power source. Is the outlet you're plugging the charger into working? You can test it by plugging in another device, like a lamp or something. If that device doesn't work either, it's probably the outlet. Try plugging the charger into a different outlet to see if that solves the problem.

Next, check the cable. The cable can be a real troublemaker. Look for any visible damage, like frayed wires or bent connectors. If you spot any damage, it's time to replace the cable. You can find a good replacement cable on our website. We have high - quality cables that are compatible with our chargers. For example, our chargers work great with cables designed for Type C PD 35w Fast Charging.

Also, make sure the cable is properly plugged into both the charger and your device. Sometimes, it might seem plugged in, but it's not fully connected. Give it a gentle push to ensure a snug fit.

Look at the Charger Itself

If the power source and cable seem fine, it's time to focus on the charger. First, check for any signs of physical damage on the charger. Is there any cracking, burning smell, or visible marks? If so, it's likely that the charger is damaged and needs to be replaced.

Another thing you can do is try cleaning the charger. Over time, dust and debris can build up in the charger's ports, which can cause charging issues. You can use a can of compressed air to blow out any dust from the ports. Just be careful not to get too close or use too much force, as you don't want to damage the charger.

Test with Different Devices

If the charger still isn't working, try using it with a different device. This can help you figure out if the problem is with the charger or the device you're trying to charge. If the charger works with another device, then the issue is probably with the original device. Maybe there's something wrong with its charging port or battery.

On the other hand, if the charger doesn't work with any device, then it's definitely a problem with the charger itself. In this case, you might need to dig a little deeper.

Check the Charger's Settings

Some PD USB chargers have adjustable settings. If your charger has settings, make sure they are configured correctly. Check the output voltage and current settings to ensure they match the requirements of your device. If you're not sure what settings to use, refer to the user manual that came with your charger or device.

Firmware Updates

Believe it or not, some chargers might need a firmware update to work properly. Check our website to see if there are any available firmware updates for your charger model. Updating the firmware can sometimes fix bugs and improve the charger's performance. We always recommend keeping your charger's firmware up - to - date to ensure the best charging experience.

Try a Reset

If all else fails, you can try resetting the charger. The method for resetting can vary depending on the charger model. Usually, it involves unplugging the charger from the power source, waiting for a few minutes, and then plugging it back in. This can sometimes clear any temporary glitches in the charger's system.

When to Replace the Charger

If you've tried all the troubleshooting steps above and the charger still isn't working, it's probably time to replace it. We have a great selection of PD USB chargers on our website. For example, our 100W GaN Super Fast Charging and 48W GaN Fast Charger are top - of - the - line products that offer fast and reliable charging.
