We’ve seen concept chargers that are designed to convert solar or wind energy into electricity to help recharge portable electronic devices. The Yoyo Mobile Phone charger concept has also been designed for the same cause, but here it harvests a completely different form of renewable energy – kinetic energy.
The charger features a built-in dynamo that converts energy from motion into usable electricity. All the user has to do is to keep spinning the device until the onboard battery is charged. Once it has accumulated sufficient charge it can be connected to a range of portable electronic devices to recharge them.
