Before I replaced my iPhone battery, I was pretty much always connected to a phone charger. It seems to be a fact of life these days for anyone using a smartphone. The problem with constantly needing to charge your phone is that your charging cord can take a beating. I've definitely used a few of my chargers to the point of frayed wires. To help protect yourself from any possible harm and to (hopefully) extend the life of your phone charger, here are five phone charger accessories that will help protect your cord.
The trouble with chargers comes when your charging cord is bent in all different directions to the point of breaking open and exposing the wires. According to ZD Net, an iPhone charger puts out 5 volts, which is reportedly enough power to lead to overheating and possibly a fire (when the frayed wires are exposed). The website also reported charging cables with frayed wires may short circuit while charging the phone and "cook the battery," which can lead to a fire.
Basically, it sounds like you want to stay away from using a phone charger that has been compromised beyond repair. Of course, you don't want to wind up constantly buying new chargers, and thanks to some helpful gadgets, you won't have to.
