Yoyo Battery charger

The design is a self-generating battery recharger using YO-YO torque.
Smartphone users normally carry a recharger when they go out for a case
when the battery is dead but it is inconvenient to find a socket.
The product is a battery recharger that can recharge by self-generation
without a socket, and YO-YO is an additional fun to the design.
