We've all had one or two charging cables fray over the years. It can be annoying -- not to mention a fire hazard. DIY enthusiast Angelica discovered a quick and easy way to protect them with an old clickable pen.
You don't actually need the whole pen for this, you just need the spring inside. After wrapping the spring around the cable and sliding it to the end, your cable should stay straight in situations where gravity might bend it so that over time it won't start to detach and fray (Apple cables are definitely the worst offenders).
