The Marinco ParkPower 50 Amp 125/250V RV cordset is a 30-foot, 4-wire extension cord that runs park or campground power to a 50-amp RV inlet. It uses the standard NEMA 14-50-style 4-pin male plug and a locking female connector, and the right-angle ends relieve strain at the pedestal and the RV inlet. It suits owners of 50-amp RVs and travel trailers who need a longer or replacement shore power cord. Against generic 50-amp cordsets, Marinco's molded ends and locking ring are the main selling points; it is a heavy, bulky cord that is harder to coil in cold weather.
