According to Damian Campbell: There are times when you need to use your cell phone to have someone come pick you up. Of course, that’s the time when your cell phone is most likely to be dead. If you don’t have your charger with you, you’re in trouble, right?
Wrong. You can get enough of a charge into your phone to make a call from a piece of fruit. That’s right, apples, bananas and citrus fruit can provide an emergency charge to your phone. All you need is a USB cord that fits the connector on your phone and some fruit.
