In an ever-evolving world of technology, USB chargers are becoming increasingly common. They are small and portable and can easily be used to charge your phone, tablet, laptop, and more. While they are designed to be plug-and-play, there may be times where you need to know how to wire a USB charger. Here we’ll discuss the basics of wiring a USB charger and what you need to know to get the job done right.

Gather the Necessary Materials

Before you get started, you’ll need to gather the necessary materials. You’ll need a USB cable, a USB wall charger, and a few tools, such as a screwdriver, wire stripper, and electrical tape. Once you have these items, you’re ready to get started.

Strip the USB Cable

The first step is to strip the USB cable. Use your wire stripper to remove the outer sheath of the cable. This will expose the four wires inside the cable. Once you’ve stripped the cable, use your electrical tape to secure the ends of the cable so they don’t fray. Now you’re ready to connect the wires.

Connect the Wires

Now it’s time to connect the wires. Using the diagram in your USB charger, connect the wires to the corresponding colors. It’s important to be sure to connect the correct wires as improper wiring can lead to damage to your device. Once you’ve connected all the wires, use your electrical tape to secure them in place.

Test the Connection

Once you’ve connected the wires, it’s time to test the connection. Plug in the USB wall charger and plug it into a power source. If the connection is good, you’ll see a light on the wall charger indicating that it is working properly. If the connection doesn’t work, check to make sure all the wires are securely connected and try again.


Wiring a USB charger is not a difficult task, but it’s important to make sure that all the connections are secure and correct. By understanding how to wire a USB charger, you can ensure that your device is properly charged and ready to go when you need it. With the right tools and a little bit of patience, you can easily wire a USB charger.
