Charger Powerbank Tenaga Kaki

Developers: Orange and Gotwind.
The device harnesses kinetic energy from an airbed foot pump that drives an embedded turbine. This energy is then converted into an electrical current that recharges your mobile phone. The company claims that about 1 minute of pumping or 60 pumps can give the user enough charge to use the phone for a 5-minute call. Though the charging system won’t completely charge a dead battery, it could still be a part of your camping emergency kit.
