Charging cell phones, laptops, and other gadgets is a necessity. Sometimes this is difficult and needs to be done on the go and occasionally you run out of power just when you can’t afford to or don’t have access to a power plug – such as in an airplane . Datexx has come up with a simple solution to your charging woes with a hand-cranked “Super Battery”.

Weighing a mere 6 ounces the 600 mA battery is said to support over 1200 devices.  When the unit is completely charged it is promised to supply up to four hours of cell phone talk time, 36 hours of standby and five hours of iPod play time. 2 minutes of cranking will give you about six minutes of talk time on your cellphone, the manufacturer says.
