Long hours of charging your handsets or cellular phones may soon become a thing of the past.

Eesha Khare, an 18-year-old girl from Saratoga, California, has invented an ultra fast charging gadget that can load power into a phone in just 20 seconds.

Dubbed as "supercapacitor," this power-storage gadget is able to dispense 10,000 recharge cycles, which is practically 10 times the performance of conventional batteries. It also comes in a tiny package that can hold power load for a much longer time, too.

Since Khare is specialising in nanochemistry, it enabled her to create a device that's much smaller than the ones people are accustomed to. 'Really working at the nanoscale to make significant advances in many different fields,' she said.

This potential breakthrough is what gave Khare the Intel Foundation Young Scientist Award during the Intel International Science and Engineering Fair held in Phoenix, Arizona this week.

When asked on what was her inspiration in doing the power storage technology, Khare took to her personal experience as a regular mobile phone user. "My cellphone battery always dies," she told NBC News.

Khare brought home $50,000 cash prize for her "supercapacitor" invention.

Speaking with much optimism as she readies herself for Harvard soon, Khare said she sees her recent recognition as only the start of bigger things to come. Soon, she hopes that her invention will also be employed to power cellphones, cars and just about anything that uses rechargeable batteries. For now, the "supercapacitor" is only used to charge a light-emitting diode or LED.

'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.'

What multinationals and big tech companies have failed to address so far, Khare already has an answer to. No surprise therefore that she has caught the attention of industry experts and is now being besieged by offers including one from tech giant Google.

There are reports that Google is now in exploratory talks with Khare on how she plans to revolutionize the technology of mobile phone battery life.
