If you have a 15A standard (not High current) it doesn't have a power port. The High Current versions do use Power Ports. You won't see much if any difference between them and Porter Ports. Both are great. The Porter Port will best the outlet in the 15A standard version easily. I use both the Power Ports and Albert's Porter Ports. I also have both the 15A standard UO and the 20A High Current UO.
