Are you still worried about how to get your phone charged (充电) ? Now, a 19-year-old teenager can help you to solve this problem. He has invented a phone charger which uses energy from your own body to charge your phone.
Hand Energy, the wonderful invention of the inventor Miehael Vaga, allows you to charge your phone simply by shaking your hand, which starts the charger's gyroscope(陀螺仪) to produce electricity. And the electricity can then either be stored or used to charge a mobile immediately (立即).
He said, " With each rotation (旋转) of your hand, the gyroscope's speed increases quickly and produces more power. The average (平均的) speed of the gyroscope is about 5, 000 rounds per minute. With this small charger, your physical energy can be turned into electrical energy and this means you can charge your phone. "
Hand Energy can help you produce endless electricity. You can use it everywhere you want. It is especially useful for people who have to spend a long time in the wild. What's more, it's friendly to the environment and helps you to exercise your wrists. It takes between 40 minutes and one hour to fully charge the batteries(电池) in Hand Energy.
The invention took Vaga a year to develop. Now, the inventor from Minsk, Belarus, is ready to put it into production and send out the creative convenient chargers.
