Rolling bag / Suitcase

Rolling bag
Rolling bag

People go abroad for pleasure, for business or for school. Everyday we do so, we bring our travel bags. This travel bag comes with a charger. The mechanism is very simple. As we move, we pull our travel bag. As the wheels rotate, mechanical energy is converted to eletrical energy. This eletrical energy is then used to charge eletronic device such as phones, cameras, etc. This travel bag is very practical since we produce eletrical energy naturally just by using our effort. Roll the wheels, get "happy energy!".
