The Apple iPhone 3G Retractable Wall / Travel Charger is an improvement over standard wall chargers included with most cell phones. This Apple iPhone 3G Wall / Travel Charger features a rapid retract wire that coils up inside the charger and out of your way. Retract the cable with the easy to use button located on the top of the home charger. Just press down to retract the full length of the cable. This cell phone charger keeps your cell phone powered up and eliminates wire tangles and mess. An IC chip allows it to remain plugged into an outlet indefinitely without damaging the battery.
