摘要: A case for an electronic device includes a front member having aperture interacting with touchscreen of the and back that rechargeable power cell, switched electrical interface, electromechanical switch, current monitoring circuitry. The interface has enabled mode in which is permitted to flow from cell installed disabled not device. switch transitions mode. circuitry automatically toggles when magnitude flowing decreases predetermined value.
