How to repair a charger cord?

My charger wire seems to have gotten weaker to the point it only works when i bend it side to side. And the power gets on and off when it’s bend. Each time i charged it has gotten worse and now it almost doesn’t work. Should i buy a new one? or can i fix it on my own?

If you are going to repair it, you may be able to splice the cord back together. This won’t work if the connector is broken but it will fix a damaged area of cord. In terms of doing the repair, refer to this guide if you are unsure of how to solder wires together. You will need a good wire stripper as well. The cheap ones without a spring aren’t worth using since the ones with it aren’t much more and nicer to use.

What you need to do is find the broken part(s), cut them off (add +~1/2” additional cord for insurance) and then solder and heatshrink the repaired wire. NOTE: You may need to use Liquid electrical tape as heatshrink has a bad habit of shrinking too early.

It’s up to you what to do this, but if you want a nicer look layer that sort of passes, layer matching length heatshrink that covers the area with a little overhang (and add a longer piece to cover the layered heatshrink to be sure). It won’t be perfect, but it'll help visually.

How I seal heatshrink is I use a butane torch using the least fuel possible - depending on the torch. I need to keep my small one (lighter nozzle) cranked up because of a permanent butane clog since it had garbage butane. That said, it works much better now with black can Zippo butane. These are generally safer then the big ones that burn hotter and wider, with less error room to worry about - if this isn’t something you’ve done before you may want to use one of the smaller torches to get a better feel for how to do it properly. You can use a larger torch like the Dremel 2200-01 if you’re comfortable with such a thing since it will burn significantly hotter. NOTE: Previous torch is subject to a CPSC recall Ronson Tech Torch

This is the butane I use since I can get it locally and it’s good quality. I have the Ronson equivalent (bought to preserve the Tech Torch warranty) isn’t as good with the same CAS#. I gave it a second chance with that Tech Torch and I didn’t like it even with a fresh can.

@tinsae this sounds like you have a broken wire. You did not tell us which end of the charger but I suppose you are talking about the one with the adapter that connects to your computer. What you can do is to cut the cable past where you bend it, strip the insulation and connect a new barrel adapter to it. You would need a 4mm x1.35mm barrel adapter to solder the stripped cable to. It is not a very complicated repair and would keep your AC adapter around instead of going to eWaste. Of course you can always replace the complete AC adapter but that somehow defeats the DYI purpose :-)

There’s a loose or intermittent connection somewhere. Since most of these devices use molded plugs, repair isn’t that easy unless you’re already handy with such things. Are you sure it’s the charger cord, and not the connection? Wiggling the cord side to side is probably wearing on the charger connector. The connector can be replaced, and the charger cord also.
