POWGRN NEMA 14-50P to 14-50R 50 ft 50A RV/EV Extension Cord — Outdoor‑Rated, STW Copper

POWGRN’s 50 ft NEMA 14-50P to 14-50R extension cord delivers a weatherproof, 50‑amp connection for RVs and Level 2 EV charging when you need extra reach.

If your campsite hookup or home charger sits too far from your vehicle, this heavy‑duty 50‑foot cord bridges the gap without sacrificing current capacity. Built for continuous 50A service at 125/250V, the cable carries high power loads safely and resists outdoor hazards like moisture, abrasion and extreme temperatures. It’s designed for EV owners and RVers who require dependable, portable power extension that meets ETL safety standards.

How does this cord support Level 2 EV charging and RV power needs?

The POWGRN cord uses a NEMA 14‑50P male to NEMA 14‑50R female configuration rated for up to 50 amps, so it can handle Level 2 EV chargers (common on many Tesla and EV models) and full 50A RV service. Its STW construction and pure copper conductors maintain low resistance under load to preserve charging rates and appliance performance.

• 50A maximum current at 125/250V for high‑power devices
• 6250W to 12,500W capacity depending on voltage and setup
• STW jacket with pure copper conductors to limit voltage drop

Is the cable durable enough for outdoor and seasonal use?

Yes — the outer jacket is engineered for outdoor exposure, offering water resistance, corrosion protection and flame retardancy. It remains flexible in very cold conditions (tested to -40°F), resists wear from repeated handling, and is built to withstand campsite and driveway use without cracking or degrading quickly.

• IP65 weather resistance against splashes and dust
• Heat resistant and flame‑retardant outer jacket
• Corrosion‑resistant components suitable for long‑term outdoor storage

What user‑friendly features make plugging and storing easier?

The design includes an insulated handle with extra grip area to make connecting and disconnecting less strenuous and safer for your hands. The cord is also flexible for coiling and includes a grip storage accessory for neat transport and less tangling in trunks, garages, or storage compartments.

• Insulated ergonomic handle for safer plug/unplug actions
• Soft but strong jacket for easy coiling and portability
• Included grip strap or storage feature to keep cable organized

What safety certifications and installation notes should I be aware of?

This POWGRN extension is ETL certified, indicating it meets applicable safety standards for electrical performance. Always verify plug type compatibility with your EV charger or RV inlet before use to avoid mismatches, and fully uncoil the cable during extended charging to prevent heat buildup.

• ETL certified for verified safety compliance
• Compare plug types to ensure NEMA 14‑50 compatibility
• Recommended: uncoil fully during charging and avoid kinks

Who is this for: This POWGRN 50 ft NEMA 14‑50 extension cord suits RV owners, EV drivers using Level 2 charging, and anyone needing a portable, high‑current outdoor extension. It’s aimed at users who want a rugged, weatherproof cable that keeps full 50‑amp service across longer runs while offering easy handling and ETL‑verified safety.
