Adopting a fairly modern look, the bag in question is equipped with two wheels rather broad. A detail that was not chosen by chance as these wheels are actually used to generate green energy. The bag is equipped with a generator, it converts the kinetic energy that the rotation of the wheels produced and transforms it into electrical energy. It will be stored in the removable battery of the bag. It only remains to connect portable devices to charge port of the bag. Smartphones, tablets, game consoles, cameras or laptops can be charged for those who prefer their high-tech devices in the beautiful scenery on the trip.
