POWGRN NEMA 14-50 Extension Cord 25 ft — 50A Outdoor EV/RV Cable, IP65 Weather-Resistant

This 25-foot POWGRN extension cable converts a NEMA 14-50 male plug to a NEMA 14-50 female inlet and is built for outdoor charging and power hookups. It supports 50 amps at 125/250 volts and is rated for high wattage loads, making it suitable for many EV Level 2 chargers and 50A RV shore power connections. The cord combines flexibility, weather resistance, and safety-minded details to simplify temporary power extension without compromising performance.

How does this cord handle outdoor conditions?

The POWGRN extension is engineered for exposure to the elements, with a robust outer jacket and components that resist moisture, heat and corrosion. Its IP65-level protection and flame-retardant materials help the cable keep working in rain or sun without rapid wear. The plug and connector are built to limit ingress and stand up to repeated outdoor use.

• IP65 waterproof and weather-resistant construction
• Corrosion- and heat-resistant materials for longevity
• Flame-retardant jacket for improved safety near heat sources

Is the cable safe for heavy EV or RV charging?

Yes — this extension is rated for up to 50 amps and supports 125/250V circuits suitable for Level 2 electric vehicle charging and full-capacity RV shore power. It uses full copper conductors and meets ETL certification requirements, provided the cord is used according to instructions and fully uncoiled during operation. Always verify the outlet and equipment compatibility before connecting.

• NEMA 14-50P (male) to NEMA 14-50R (female) configuration
• 50A maximum, supporting up to 6250/12500 watts depending on the circuit
• ETL listed when used correctly and fully extended

How easy is it to plug, unplug and store?

POWGRN added ergonomic touches to make daily use less cumbersome: insulated handles and extra gripping area for safer, easier connections. The cable remains pliable in very cold temperatures, so it won’t stiffen and become difficult to manage. A built-in grip-style storage aid helps keep the cord tidy when not in use.

• Insulated handle with extra space for secure gripping
• Flexible material performs down to -40°F without cracking
• Integrated grip for compact, tangle-free storage

What mounting or compatibility checks should I do before using it?

Confirm that both your supply outlet and the device inlet use the four-pin NEMA 14-50 configuration — this cord matches that standard precisely. Make sure the cable is fully uncoiled to avoid heat buildup and check that circuit breakers and wiring support 50 amps. If in doubt, compare plug shapes and consult a qualified electrician for installations that will be long-term or permanent.

• Verify four-pin NEMA 14-50 receptacle compatibility
• Always run the cable fully extended during charging or heavy loads
• Use a licensed electrician for permanent wiring changes or questions

Who this is for: This POWGRN 25 ft 50A extension cord is aimed at EV owners who need a dependable Level 2 extension, RV enthusiasts requiring shore power flexibility, and tradespeople who need a portable 50-amp outdoor power link. Choose it if you want a weather-resistant, ETL-listed cable with ergonomic handles, full-copper conductors, and a length that balances reach with manageable storage. If your setup uses a different plug type, confirm compatibility to avoid unsafe connections.
