A teenager in California created a 20-second cell phone charger, winning a $50,000 prize on Friday, it was reported.

Eesha Khare, 18, of Saratoga, got the Intel Foundation Young Scientist Award for creating a storage device that can be charged in between 20 and 30 seconds.

“My cellphone battery always dies,” Khare told NBC News as to why she chose to work on the project.

The super-capacitor that she came up with can fit inside a cell phone.

“The best part of my project was seeing its practical application. After charging my super capacitor for 20 seconds, I was able to light a LED device and that’s an amazing accomplishment,” Khare told DNAIndia.

She added that the device can last for 10,000 charge-recharge cycles, more than 10 times more than normal rechargeable batteries.

The device has only been tested on LEDs but NBC reported that the device might be able to work on other devices.

“It is also flexible, so it can be used in rollup displays and clothing and fabric,” Khare said. “It has a lot of different applications and advantages over batteries in that sense.”
