Charger cables for cell phones usually last only a few years before the insulation starts fraying on the ends. Replacement cables cost $8 to $30, but there’s a cheaper solution. If the insulation is cracked but the copper wire inside is still intact, try covering the crack with a couple of layers of liquid electrical tape ($5 to $10 per bottle). Performix and Gardner Bender are two brands that get lots of positive reviews online. Just be sure not to let the cable touch anything until the liquid tape dries completely.
