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.
