Turn the motion of walking into usable power. The Go Kin Pack is “powered by you,” generating electricity through the motion of walking. It’s compact and lightweight, so it fits in the bottom of a specially designed day pack or fanny pack. (Or, Go Kin Packs can supply an adaptor kit for your existing pack.) Two retractable cords extend from the bottom of the pack to hook on the tabs at the back of your running shoes or hiking books. Each time you take a step, the cords engage gears, electronics and motors in the Go Kin, creating electricity.
