POWGRN NEMA 14-50P to 14-50R 25 ft 50A RV/EV Extension Cord — Weatherproof, ETL-Certified

POWGRN's 25-foot NEMA 14-50P to 14-50R extension cord delivers a weatherproof, 50‑amp connection for Level 2 EV charging and heavy-duty RV power needs.

This heavy-duty extension cable bridges NEMA 14-50 outlets and devices—ideal for EV chargers, motorhomes, and shore power pedestals. Built to handle up to 50 amps at 125/250 volts, the cord combines flexible insulation, durable jacket materials, and an ergonomic grip so you can plug and unplug safely outdoors. ETL certification and copper conductors ensure the cable meets common safety and performance expectations when used as directed.

How does this cord handle outdoor conditions?

The POWGRN cord is engineered to withstand weather and heavy use. Its outer jacket resists water, heat, corrosion, and abrasion so it holds up at campsites, driveways, and garage areas. The cable stays flexible in cold conditions and is flame-retardant to reduce surface ignition risk.

• IP65-level protection against water spray and dust ingress
• Wear- and corrosion-resistant jacket for long-term outdoor exposure
• Maintains flexibility at very low temperatures (-40°F)

Will it work with my EV or RV equipment?

This extension uses NEMA 14-50P (male) to NEMA 14-50R (female) connectors—the common standard for many Level 2 EV chargers and 50A RV shore power. Confirm your plug and inlet are the NEMA 14-50 four-prong configuration before use. The cable is rated for up to 50 amps, suitable for many EV chargers and RV distribution panels.

• Compatible with many Level 2 EV chargers (e.g., Tesla mobile chargers with adapter)
• Designed for 50A RV pedestals and outlets
• Four-pin NEMA 14-50 connector—verify plug/inlet match before connecting

What safety and usability features are included?

POWGRN added practical touches to make handling and safety straightforward. An insulated handle provides larger gripping area for secure plugging and unplugging, reducing strain on the cord ends. The product is ETL certified and uses pure copper conductors for stable electrical delivery when fully deployed.

• Ergonomic insulated grip for easier, safer connection changes
• Pure copper wiring for reliable current transfer
• ETL certification indicating testing to recognized safety standards

How should I care for and use this extension cord?

To keep the cable safe and operating as intended, fully straighten the cord during use to avoid heat buildup from coiling. Store dry and protected when not in use, and inspect connectors for damage before each season. Never exceed the rated 50A current and ensure your breaker and equipment are compatible.

• Unfold the entire length before charging to reduce heat risk
• Store with the included grip strap to prevent kinks and tangles
• Inspect periodically for cuts, nicks, or connector damage

Who is this for? This POWGRN 25 ft NEMA 14-50 extension cord is aimed at EV owners who need reliable Level 2 reach, RVers who require flexible shore power connections, and anyone who wants a weather-resistant 50‑amp cable for outdoor heavy-duty electrical use. It's a practical choice if you require a portable, durable extension cable with familiar NEMA 14-50 fittings and straightforward safety features.
