Abstract: A portable, cordless, battery powered microwave food warmer is sized and powered to be portable. The food warmer has feet on the bottom and the back to accommodate both upright and laid-back orientations.

Abstract: A combined flashlight and lantern can have a light powered by a metal-air fuel cell that runs, or is activated, by water or an electrolyte such as salt water. The combined flashlight and lantern has both flashlight and lantern configurations. In the flashlight configuration, a head with a distal concave reflector is disposed towards a handle with the light in an aperture of the distal concave reflector to direct light axially. The distal concave reflector is opaque to resist light from emitting laterally therefrom. In the lantern configuration, the head with a distal convex reflector is disposed away from the handle and opposing a proximal convex reflector to direct light radially.
