A portable generator system includes an interface mounting element for supporting a selected engine, from a plurality of engines, with a vertically oriented output shaft when the generator system is positioned on a substantially horizontal surface. A generator is directly coupled to the output shaft of the engine and rotates therewith about a common axis. The generator is selectable from a plurality of generators having different output power characteristics. A movable support cart supports interface, engine and generator and is formed of a single piece of tubular stock. The tubular stock is bent to form two substantially parallel, displaced, U-shaped regions bounded by a third U-shaped region substantially perpendicular thereto wherein the interface element, the selected engine and the selected generator are supported and protected. The cart supports first and second displaced wheels which rotate about a common axis which extends between the first and second regions, parallel to the third region. A fuel tank is carried on the cart and extends from the first side of the axis while the interface extends from the second side enabling the fuel tank to counterbalance the weight of the selected engine, the selected generator and the interface about the axis of rotation of the wheels.
