Using this cable is super easy. First, plug one end of the cable into the Lightning connector of your iPhone, iPad, or iPod. Then, connect the other end to your computer's USB port if you want to sync data or charge your device. If you prefer to charge from a wall outlet, plug the cable into the Apple USB Power Adapter and then into the outlet. When using, make sure your device and the connection ports are clean. Avoid bending the cable too sharply as it may damage the internal wires. To keep it in good condition, store it in a cool and dry place when not in use.
