Orange Dance Charge!
Orange has come out with a charger that will provide that extra juice for your portable electronics. It has been released in accordance with the music festival which will keep your feet moving and your hands swinging. The Dance Charger is a prototype kinetic charger. With assist by GotWind, the 4.25 x 2.5-inch / 180-gram velcro and elastic band converts your chemically-fueled, backbeat twitches into electrical current with the help of a system of weights and magnets. This in turn charges an embedded battery for topping off your portable electronics throughout the multi-day music festival.
Now this music festival isn’t happening in India but one can be sure to use this come December at Goa’s Sunburn trance festival.
