19-Year-Old Teen Invents Phone Charger That Uses Power From Your Body

A new gadget means smartphones can now be charged using the power of the human body.
HandEnergy allows users to charge the battery on their phone simply by rotating their hand.
This motion activates the device’s gyroscope to produce energy that can then either be stored or used to immediately charge a mobile.
The innovative gadget, which received more than Euro £50,872 in Kickstarter funding, is the brainchild of 19-year-old inventor Michael Vaga.
Mr Vaga, who lives in Minsk, Belarus, said: ‘With each rotation of your hand, the rotor speed increases significantly and generates more power. The average speed of the rotor is 5,000rpm.

‘We translate the mechanical energy you put in into electrical energy and this means you can charge your device.’
He said that the product, which took more than a year to develop is ideal for people who travel frequently or are often away from power sockets.
It takes between 40 minutes and one hour to fully charge the batteries of the HandEnergy device and this speed is reduced by 30 per cent if a phone is being simultaneously charged.
Mr Vaga and his team believe the HandEnergy device, as well as providing emergency energy on the move, is especially useful as it produces clean energy without the need to burn fuels.
Frequent users of HandEnergy can monitor how much energy they have produced using the gadget’s accompanying mobile app.
Mr Vaga said: ‘It’s a superb feeling when a project you have developed for many years not only keeps moving, but actually picks up the pace.
‘All of our reviews have been great. People admired the project and were happy someone came up with a device that will save them from power shortages.’
HandEnergy is currently scheduled to roll out in March 2017 with an expected retail price of Euro 99 (£84).
