Care for Your Charger
One of the worst things you can do to a charger is to bend the cord in a way it isn’t meant to move. Bending your charger can have ill effects on the wires within the cable, possibly loosening them from their connections or even causing them to break.

Loose and broken wires can be a fire hazard. To avoid this danger, never force your charger cord into a position that it doesn’t naturally go. For example, gently wind the cord into your bag if you are traveling. This will help keep your charger working at maximum capacity for a long time.
