Water-Powered Phone Chargers

For consumers who are looking for a greener way to charger their phone, there is now a pocket-sized fuel cell charger that runs on water.

Dubbed "the world's smallest pocket sized fuel cell charger," 'JAQ' is a portable device that uses water, salt and fuel cells to charge your phone. The device itself resembles a small pouch that connects to your phone via a USB charging cable. To juice up your phone, simply pop in a small fuel cell. According to JAQ, this cell "fuels electricity-producing chemical reactions when you slip the card into the port," allowing it to charge up your phone without electricity. The device can even be used to charge tablets and other small appliances, provided you have more than one fuel cell card on hand.
