Japanese studio Nendo has developed a manually powered battery that is designed to be used in emergency situations.
Called dequl, the portable battery is able to charge devices such as smartphones via micro USB cable.
“When in disaster, securing power supply for smartphone means having access to basics such communication and lighting,” said Nendo in a statement. “A mobile battery could be an effective source of power and this one was developed to be charged at home and grabbed in case of an emergency, rather than to be carried all the time.”
Using a charging dock to power the battery while at home, the portable battery can be manually charged by hand in the case of an electrical blackout.
Designed to generate power via centrifugal force with only one hand, a stick is extended and twisted horizontally in order to be swung around.
Taking advantage of the velocity used to swing the stick, a lithium battery is positioned on the tip of the stick to utilize the weight and maximize energy.
