Our take on the 25FT 50 Amp RV Extension Cord with Adapter 15Amp to 50Amp 250V Heavy Duty 6/3+8/1 Gauge Pure Copper STW Wire UL ETL Listed 4 Prong 14-50P 14-50R Weatherproof Suit for Generators Camper

A 25-foot 50 amp RV extension cord built from 6/3+8/1 gauge pure copper wire, rated 250 volts and 12,500 watts, with NEMA 14-50 plugs at both ends. It ships with a 15A-to-50A adapter (NEMA 5-15P to 14-50R) so a 50 amp rig can draw from a standard campground receptacle, plus a cord organizer. The heavy-duty flame-retardant PVC jacket is made for rain, snow and dirt at the campsite. It suits RV owners who need extra reach to a pedestal or generator; the adapter is a convenience, not a way to run a full 50 amp load from a 15 amp outlet.

About the 25FT 50 Amp RV Extension Cord with Adapter 15Amp to 50Amp 250V Heavy Duty 6/3+8/1 Gauge Pure Copper STW Wire UL ETL Listed 4 Prong 14-50P 14-50R Weatherproof Suit for Generators Camper

This 25-foot, 50 Amp extension cord extends the distance between an electrical outlet and an RV, camper or electric vehicle. It can also be used to plug in larger outdoor items such as generators. It works indoors, in the garage, at the campsite and in the backyard.

The cord uses 100% pure copper 6/3+8/1 gauge wire. A heavy-duty PVC jacket that is flame-retardant and heat-resistant protects the wire from wind, rain, snow, soil and rocks. The cord is fluorescent green, which makes it easy to find in dark or low-light conditions. It has NEMA 14-50P and NEMA 14-50R connections and is rated for 250 volts and 12,500 watts.

An included adapter (NEMA 5-15P to NEMA 14-50R) connects a 15 Amp campground receptacle to a 50 Amp RV service. The cord is UL and ETL certified for use in the U.S. and Canada.

Questions and answers

Can this cord run my RV's air conditioner?
Yes, on a true 50 amp pedestal it carries the full 12,500 watts your RV service needs, including the air conditioner. Through the 15A adapter, the outlet still limits you to 15 amps, so run only light loads.
What is the 15A-to-50A adapter for?
It plugs a standard NEMA 5-15 receptacle into the cord's 14-50 end, letting a 50 amp RV connect at campgrounds that only offer household-style outlets. It adapts the plug shape, not the available power.
Is it safe for outdoor use in rain and snow?
The jacket is flame-retardant, heat-resistant and made to withstand wind, rain, snow, soil and rocks. Keep connections off the ground and protected from standing water.
What comes in the box?
One 25 ft 50 amp extension cord, one 15A-to-50A RV power adapter and one cord organizer.
Does it work with generators?
Yes. The 14-50 ends fit generators with a NEMA 14-50 outlet, and the adapter lets you connect to a standard 15 amp receptacle when needed.
