A wheeled, manually movable, internal combustion engine powered electric generator is mounted in a rigid frame formed of tubular steel elements. A pair of aligned wheels is pivotally mounted to each opposite side of the frame, and one pair has a locking mechanism. The electricity generating components are mounted to the bottom of the frame. The battery and trickle charger are carried above the engine in a locked compartment. The engine's muffler is disposed beneath the upper outline of the engine to free space for accommodating the battery and the fuel tank, which is completely within the outline of the frame and holds more than 12 gallons of diesel fuel. The frame also supports and contains a locked compartment that houses the electric connector that is used to connect the electric output of the generator to the load.
