An auxiliary male twist-lock plug-adapter for converting a female twist-lock plug-adapter to male. The male adapter is a disc defining an upper and a lower face. Three twist-lock electrode-prongs project from the upper surface, and three conventional electrode-prongs project from the lower surface. Either of the two sets of three prongs may be coupled to the female twist-lock plug adapter so that the other, uncoupled set may be connected to a conventional female plug or to another female twist-lock plug adapter.
