POWGRN 100 ft NEMA 14-50 Extension Cord — 50A Outdoor Weatherproof, Flexible STW Jacket

POWGRN's 100-foot NEMA 14-50P to 14-50R extension cord delivers a heavy-duty, weatherproof 50‑amp connection for Level 2 EV charging and RV power where the outlet is far from your vehicle.

If you need extra reach for an RV pedestal or an EV charging location, this POWGRN 50A, 125/250V extension cord gives you a long-reach solution built for outdoor use. The cord combines a high-current NEMA 14-50 plug and receptacle with a flexible, durable jacket and ETL certification, making it suited for campsites, garages, homes, and mobile charging setups. It’s designed to withstand wet conditions, temperature swings, and repeated handling while keeping a stable power delivery for onboard heaters, appliances, and Level 2 chargers.

How does this extension cord handle outdoor weather and rough use?

The POWGRN 100 ft 50A cord features an IP65-rated, STW jacket that resists water, abrasion, corrosion, and heat. Materials and construction are chosen to endure sunlight and temperature extremes without cracking or shorting. It also includes flame-retardant properties for safer use around equipment.

• IP65 weather resistance keeps moisture and dust out of critical areas
• STW-rated flexible jacket resists wear and UV exposure
• Flame retardant and corrosion-resistant components for longevity

Will this work with my EV or RV, and what power can I expect?

This cable uses a NEMA 14-50P male to NEMA 14-50R female wiring pattern compatible with many Level 2 EV chargers and 50A RV pedestals, including common Tesla adapters and RV shore power. It supports up to 50 amps at 125/250 volts under appropriate conditions; note that voltage drop may reduce safe current when run long distances—above 50 feet current capacity can be effectively limited.

• NEMA 14-50P to 14-50R wiring for Level 2 EV charging and RV shore power
• Rated for 50A, 125/250V, with 6250/12500W maximum capacity under ideal conditions
• Expect reduced effective amperage beyond 50 ft; plan charging or appliance loads accordingly

How easy is it to plug, unplug, store, and use safely?

The POWGRN extension cord includes an insulated, ergonomic handle to make connection and disconnection easier and safer, reducing strain on the plug and wiring. The cable remains flexible down to -40°F, so it won’t become rigid in cold weather and is easier to coil for transport and storage. The included grip/storage solution helps you keep the long cord tidy when not in use.

• Insulated handle improves grip and reduces wear at the plug
• Flexible at very low temperatures for reliable cold-weather performance
• Convenient storage grip helps prevent tangles and abrasion during transport

What safety certifications and construction details should I know?

This extension cord carries ETL certification, indicating independent testing to applicable safety standards for electrical products. Internally it uses pure copper conductors for consistent conductivity and minimal heat buildup, and the cable jacket includes heat-resistant features to meet outdoor usage demands.

• ETL-certified for electrical safety and code compliance
• Pure copper conductors for efficient power transfer
• Heat-resistant construction and flame-retardant jacket materials

Who is this for: The POWGRN 100 ft NEMA 14-50P to 14-50R extension cord is aimed at RV owners, mobile EV users, electricians, and homeowners who need safe, long-reach 50‑amp outdoor power. It’s a practical choice when your vehicle or charging point is too far from a pedestal or outlet, when you require a rugged cable that tolerates weather and handling, or when you want the reassurance of a tested and certified heavy-duty extension for appliances and Level 2 charging.
