Battery box

Abstract

This item comprises a case body and a lid. The lid is detachable from the case body. Four D-size batteries are stored inside the case body, and the case is used as a mobile charger for smartphones by connecting it to a mobile phone such as a smartphone via a cable. The center portions of the right and left sides of the case body are recessed inward from the edges, so that when holding the case body in one's hand to carry it, the fingertips of the hand are positioned in the recessed portion of the center of the case body, making it easy to hold the heavy item containing four D-size batteries without slipping or dropping it.
