A wheeled, manually movable, internal combustion engine powered electric generator mounts in a rigid frame formed of tubular steel elements. A pair of aligned wheels is pivotally mounted to each opposite side of the frame. One pair of aligned wheels is provided with a locking mechanism that enables both the front and rear wheels to be locked against rotation. The electricity generating components mount to the bottom of the frame. The internal combustion engine mounts toward the rear end of the frame. A propane fuel tank is carried above the engine by the upper rear portion of the frame. A battery and a trickle charger are carried above the engine and secured in a compartment with a locked hinged cover. 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.
