A Chimpy Powerbank is an external rechargeable battery including a charging cable by the company Chimpy. In this sense, it is a power bank which you don't buy, but rent. Chimpy Powerbanks are green, they have a monkey logo on them and they always come with the required cable. Furthermore, Chimpy Powerbanks are exclusively charged with solar electricity. Thus, a Chimpy Powerbank always comes from Chimpy, makes sense, right?
