Abstract
A multi-power source is described that provides power through a single source—e.g. rechargeable batteries—whose charge is maintained through four or more different power sources. Examples of such power sources are taken from a group consisting of disposable batteries, mechanical energy as developed through a crank, solar power, an external DC source such as provided through a car battery connection, and an external AC input as from an in-wall outlet. The power source is used to power an emergency multifunction tool, such as a modular light source having a flashlight, lantern, siren, flasher, and radio functions powered from the multi-power source.
