NEMA 14-50P to NEMA 14-50R 50 Amp RV/EV Extension Cord Outdoor with Grip Handle, Flexible 4 Prong Heavy Duty RV Power Cord

  • Secure 4-Prong Straight-Blade Connection: NEMA 14-50P male plug connects to outlets, while the 14-50R female receptacle mates with RV/EV cords; the design provides a firm, grounded fit to minimize accidental disconnection, enhanced by molded grips.
  • Ergonomic Grip Handles: Integrated molded handles on both ends provide a firm, non-slip hold for effortless plugging/unplugging, even with gloves or in low light.
  • Heavy-Duty Flexibility: 6/3+8/1 AWG stranded copper wiring stays pliable in cold weather down to -40°F, preventing cracks while handling 50A loads continuously.
  • Weatherproof Durability: Sealed connectors and STW jacket protect against rain, dust, oil, and abrasion; rated for outdoor exposure with flame-retardant materials.
  • Enhanced Safety and Convenience: Many models include LED power/ground indicators for instant status checks; compact cord organizers or storage bags prevent tangles during transport.
  • Versatile Compatibility: Perfect for RVs (e.g., travel trailers, fifth-wheels), EVs (up to 32A charging), and generators; supports U.S./Canada NEMA standards without adapters.

NEMA 14-50P to NEMA 14-50R 50 Extension Cable

This rugged NEMA 14-50 extension cord is a premium solution for high-power outdoor applications, including RV shore power hookups, Level 2 EV charging (e.g., Tesla Wall Connectors or J1772 adapters), generators, and heavy equipment like welders or pumps. Featuring a 4-prong grounded design (two hots, neutral, ground), it supports dual-voltage operation up to 12,500 watts at 250V, delivering reliable power without significant voltage drop even over extended lengths. Built with a flexible STW jacket and ergonomic grip handles for easy handling, it’s fully waterproof and UV-resistant for all-weather use in campsites, driveways, or job sites. UL-listed models ensure safety compliance, and custom lengths from 10 to 100+ feet are available for bespoke RV or EV setups, often including extras like LED indicators and storage bags. Note: The NEMA 14-50 configuration is a straight-blade (non-locking) connector, relying on the grip handles and secure fit for stability rather than a twist-lock mechanism.
