How To Fix A Broken Charger Cord In 4 Simple Ways

The first few tips help you determine if your cable is the problem.

Check if your charger is compatible

How do you know if your charger is compatible? The first thing is to check the voltage of your charger. The voltage of chargers can vary from country to country, so you must check the label on the back of your charger and ensure it matches the power supply in your country.

You should also check if your phone supports fast charging and whether or not it has a USB-C port. These are becoming more popular these days.

Check the battery’s age

If the battery is old, you might need to replace it. But if it’s in good condition, there could be a problem with the charger cord.

Clean the USB port

The USB port is the most vulnerable part of your device. It’s prone to damage because you constantly plug in and out of the device. It can cause dirt, dust, and debris to get into the port, resulting in a short circuit or data loss.

Use a dry toothbrush or compressed air duster to remove debris clogging up the ports. Then use a cotton swab with rubbing alcohol or water to create a damp environment for any leftover dirt particles hiding inside the port. But be gentle to avoid damaging the USB port.

Check if your charger is damaged

Knowing if your charger is damaged before you plug it in is critical. If the charger is damaged, it can lead to electrical problems or even a house fire.

There are many ways to check if your charger is damaged.

  • The first way is to look at the cable and see if there are any cuts or exposed wires.
  • Another way to check for charger damage is to look for discoloration of the plastic near the area where you would plug in your phone.
  • You can also smell your charger and see if it has a burning smell.

Use a different outlet to see if your device can still charge

Try plugging it into another outlet to test your device’s ability to charge. It’s a good test to see if your device can still charge.

If you have an iPhone, plug it into the charger and see if it starts charging. And if you have a Samsung, plug in the charger and see if the battery icon starts to fill up.

If your device doesn’t charge or starts charging, there could be a problem with the battery or power cord.

Restart your phone to see if it can still charge

Restarting your phone can fix a variety of problems. For example, if you reboot your phone and it starts to charge again, you may have a faulty charger or cable that you need to replace. If this doesn’t work, it could be a hardware issue with the battery or power source.

Ensure the cords are correctly connected to see if your device can still receive power

The phone should display a lightning bolt on the battery icon when you plug your charger in. If it doesn’t, your cable is not connected properly.

To charge your device, plug the charger into an electrical socket and then connect the other end of the charger cable to your device.

Before connecting the charger cable to your device, check that it is not damaged or frayed. Check that it has not been pulled out of its socket. Do not use the cable if either end has a problem. Buy a new one instead.

Try a different adapter or cable

If your device is not charging when you plug it in, try a different adapter or a charger cord to see if it can receive power. If you’re using a USB cable, try another one to see if the problem is with the cable.

If your device still does not charge when plugged in, it might be the best time to replace the battery.

Now let’s dive into detailed methods to fix a broken charger cord.

Method 1: Use a hairdryer or light bulb

You need the following materials:

  • A hairdryer or light bulb
  • Alcohol
  • Pliers or tweezers
  • A small piece of electrical tape

To fix a broken charger cord, you need to clean both ends with rubbing alcohol and then use a light bulb or hairdryer to heat one end of the cord. Then, while it’s still hot, use pliers or tweezers to grab onto one end of the wire and pull it through until you see an inch or so of exposed wire at each end.

Next, twist together both exposed wires attached to both ends of the broken charger cord and then wrap them around about three times before turning them together again at the ends.

Use your scissors to cut a small piece of electrical tape and wrap it around one of the wires you have just created. Wrap the wire not covered in tape around one hand tightly to form a loop like an opening.

Use your other hand to do the same thing with a wire from the other side of the power cord. Wrap your charger cable several times.

Method 2: Heat shrink tubing

You need the materials below:

  • Heat shrink tubing
  • Heat gun or hairdryer

You can buy the heat shrink tubing at the Amazon store. It comes in many sizes, so ensure you get the right size for your charger cable.

Heat shrink tubing is a type of polymer that shrinks when you heat it. It provides protection and insulation for your cables and wires. The heat shrink tubing will cover the exposed wires to protect them from damage.

Cover the broken area of your cord with heat shrink. Use the heat gun to heat the tubing so it can form around your damaged cable in a tight fit. The tube will then shrink to its original size as soon as it cools down again.

Method 3: Use Sugru


  • Sugru

Sugru is a putty-like substance that you can use to fix a broken charger cable. It’s moldable, so you can make it into any shape you want. It’s also waterproof and heat resistant, so it’ll not melt when a charger cable touches it.

Mold Sugru around the damaged cable part and let it stay for a day. You’ll have a robust charger cord.

Method 4: Use a Soldering Iron


  • Soldering iron
  • Soldering wire
  • Cutting tool
  • Glue gun

Soldering is joining two or more pieces of metal together by melting and flowing a filler metal (solder) into the joint.

Step 1: Cut off the damaged cable in a straight line with your cutting tool, then remove all the insulation.

Step 2: Remove any solder that has leaked during use.

Step 3: Make a mental note of the wire colors, which are red, white, green, and black.

Step 4: Solder one end of the new cable to one end of the old cable using a soldering iron and solder wire.

Step 5: Solder the two ends of the new cable together.

Insulate the wires with a glue gun, so they don’t touch each other.

Step 6: Then, wrap them with electrical tape or heat shrink to keep them in place.
