A portable reciprocating air compressor unit (32a) is driven by an electric motor (58) that is attached to an electrical circuit having a predeterminable current capacity. A manually controllable valve mechanism (68) mounted to an inlet (71) of the compressor, allows for control of the amount of air that a piston (69) draws and compresses during each reciprocation. The amount of electric current used by the electric motor (32a) to drive the piston (69) depends on the amount of air drawn and compressed. A user can therefore control the amount of electric current that the compressor unit (32a) uses.
