Power is generally supplied "by" a plug "to" a receptacle. Cables are available with one in-line receptacle fanning out to a number of plugs, so that many devices may be supplied by one supply. As the use of a plug implies a cable, even a short stub, some power supplies carry panel-mounted receptacles instead to avoid this cable, "i.e.", the normal convention of power from plug to receptacle is reversed. Cables for such cases are available with a plug at each end, although cables or adapters with two "receptacles" are not widely available.
