How to Charge a Cell Phone without Power

In a bind, this YouTube video shows how to charge a cell phone without power. Using a phone charger, key and 9-volt battery, it is possible to draw current from the battery to induce a charge. The video does not discuss whether a full charge is possible but it does show an easy method that will hopefully produce enough of a charge to make an emergency phone call. Note that I did not actually run the test myself so proceed with caution if your phone costs more than your car.
