  • Take wires’ ruined areas away and adjust the length for a seamless connection.
  • Delete nearly a 0.2-centimeter layer of insulating material on the cord is all sides.

It would be better to be on the safe side and use tape to enhance insulation and secure the cord. When everything is done, try to connect the wires using a crimper. Is it okay? You have coped with a broken charger!

What if the Charger Adapter is Damaged

How to Fix Your Cable with Sugru

How to fix a broken charger to make it serve as long as possible? Surgu is the modern material for a reliable sticking to many materials like plastic, metal, ceramics, and others. Initially soft and malleable, Sugry becomes a heavy-duty silicone rubber in 12-24 hours. Moldable glue is the most advanced tool to fix things when the charger is broken.

Sugru makes safe bonds without damaging surfaces, resistant to water and temperatures from 0 to 350 degrees Fahrenheit. And no mess around! Although this glue is the material for many applications, it is perfect for strengthening power cords and fixing electronics.

Is it easy to use? It is so simple that it can be comparable with Play-Doh. Let us see how to make a charger work again using Sugru.

Step 1: Open your Sugru

It would be best to prepare the cord first to make your charger work, meaning cleaning up the surface to ensure the adhesive compound will hold onto it. To that end, one can use a rag dipped in rubbing alcohol. Once the cable is free of debris, dry it by ridding off any alcohol residue.

Opening your Sugru is the next step. Unpack the sticker, take the glue, and thoroughly knead it up for about half a minute until it feels consistent.

Step 2: Stick It to the Surface

When your Surgu is mixed up well, roll it into a long sausage and flatten it a little to cover the necessary area on your cable. Thus, the material is ready to adhere and help you get your charger to work. So, stick the prep circuit to your cleaned cord. While proceeding, bear in mind molding the glue as quickly as possible before it starts drying up.

Step 3: Give It the Desired Shape

Do you want to get a charger to work and brag about the quality job? First, make sure you have tightly wrapped Surgu around the cable’s surface. Then, when you are done shaping it, try to rub it to make the glue’s surface even and smooth.

Step 4: See How it Becomes the Rubber

Since the material takes up to 24 hours to turn into silicone, leave your upgraded cable untouched to let it dry completely. As soon as Surgu dries, you get a sturdy and reinforced cord to feed your mobile device hassle-free. Now, you can call your friend, brag about your success, and advise how to fix a broken charger.
