Our take on the SPEEDWOW 20 FT 50 Amp RV Extension Cord, 125/250V Heavy Duty Extension Cord with Generator Inlet Box, 6/3+8/1 Gauge STW ETL Listed, NEMA 14-50P to SS2-50R, Waterproof Power Cord for RV Outdoor Home

This is a 20 ft, 50 amp RV power cord built from 6/3 + 8/1 AWG copper wire, rated for 125/250V and up to 12,500W. It runs from a NEMA 14-50P male plug to a NEMA SS2-50R female connector and ships with a matching NEMA 3R inlet box, cable winder and mounting hardware. The heavy 6-gauge copper and ETL listing put it in the same class as premium RV cords, while the included inlet box makes it a fuller kit than a bare cord. It suits RV owners, generator users and anyone running high-draw power outdoors.
