How to Fix IPhone Chargers with Heat Shrink Tubing
With so much technology lying around, you're bound to wind up with a few split and damaged wires over the years. Your cables get tugged, bent, and pulled on a day-to-day basis. It won’t be long before your cables start to wear down. Chargers tend to tear––usually at the worst possible moments–– and then you’re stressed and left at 4% battery life.

You might think you’ll save yourself a few bucks by keeping a damaged wire, but these can quickly become dangerous, especially around liquid or pets. Trying a quick solution such as electrical tape might also seem like an easy fix. But with use, it will wear down and need to be replaced eventually anyway. Instead, there is a more permanent and painless solution to restoring your cables: heat shrink. Using heat shrink tubing to fix iPhone chargers wires can renew them so that you’re not forced to buy a new one, but are also not at the risk of shock or injury from exposed electrical.
How to Fix iPhone Chargers with Heat Shrink
Heat shrink will give you equal amounts of protection and durability, and provide just as much coverage as the original jacket of the cable did. It’s a much more secure solution than any other temporary fix for your wires and will last much longer as well. In just a few simple steps, you can get your cables back to working good as new.
The first thing you’re going to need to do is get the correct measurement of heat shrink to fit your charger. For these projects, we recommend the ⅜” 3:1 Polyolefin single wall heat shrink. You can also use an adhesive lined heat shrink (otherwise known as dual-wall heat shrink), but it will be very thick. In short, the 3:1 or 2:1 Polyolefin heat shrink will provide more than enough protection. Then, you’re going to want to ensure that the heat shrink is cut to fit around the charger securely, with room for overlap.
Now you can slide the heat shrink over the charger. Make sure that the heat shrink completely covers the damaged portion of the wire. The heat shrink should overlap with the plastic part of the plug slightly, so that it can stay secure and cover all necessary areas of the charger.
Once you’ve covered the damaged area of the charger, use a VT-1000 heat gun to melt and mold the heat shrink to the charger. Be extra careful during this step, and take precaution so as to not burn yourself or further damage the plug.
After you have finished heating the heat shrink to the charger, allow the final product to cool down completely before use. Now your charger is secured and good as new!
With just a few simple steps and some heat shrink, you’re able to fix any broken electrical wiring. This method is extremely effective and functional, will last a long time, and will save you unnecessary spending on new wires in the future.
