Charging phones in hours will soon be past as an 18 year old high school student of American state of California, Esha Kharay, has presented an important scientific invention in a 2013 international science show and won $50,000 reward.

She has invented an energy saver device that can charge your cell in 20 to 30 seconds. It is named ‘Supercapacitor’. It can store lot of energy in small space and it runs battery of your phone after charging it completely. It can go to 10,000 recharge cycles while the previous batteries are limited to just 1000 cycles.

Esha Kharay has also run one LED with her supercapacitor. In near future, she will install it in a cell phone and other modern electronic devices.
