At first glance, this might look like a usual piece of pipe that you’ll find in the plumbing section of a hardware store. However, you’ll be surprised to know that it’s an emergency charger for your small electronic gadgets that will keep you safe during a doomsday-like situation. Called “Denqul,” it’s been designed by a Japanese brand called Nendo and uses the kinetic energy created by swinging-motion to charge the internal battery pack. The cylindrical charger has a telescopically extendable design and lengthens to nearly twice its size. It has a hinge in the middle that lets the baton bend into an L shape, which can be swung by one hand to produce electricity. According to Nendo, they tried both solar charging and hand cranking mechanisms for the charger but found that the swivel design to be more efficient.
To make the spinning action easier for the user, Nendo has positioned the lithium battery at the tip, in order to use its own weight to make the spinning motion more efficient. While the Denqul has been designed for emergency use, the charger can also be used as a desktop item as an organizer for your stationery, eyeglasses and also as a charging station for your smartphone. The charger is available in three muted shades of grey with a matte finish.
