POWGRN NEMA 14-50P to 14-50R 10 ft 50A Extension Cord — Outdoor Rated, ETL-Certified Heavy-Duty

POWGRN's 10-foot NEMA 14-50P to 14-50R extension cord delivers a weatherproof, ETL-certified 50 amp connection for RVs and Level 2 EV charging needs.

This heavy-duty extension cable is built to bridge a NEMA 14-50 outlet and device with the same receptacle type, giving you extra reach without sacrificing amperage or safety. Rated for 125/250 volts and up to 50A, the cord is engineered for outdoor use, cold-flex performance, and repeated plugging and unplugging for RV parks, garages, campsites, and home EV charging installations.

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

The POWGRN 14-50 extension transmits the full 50-amp circuit required by many Level 2 chargers and RV service panels, helping maintain charging speeds and onboard power systems. It matches a NEMA 14-50P male to a NEMA 14-50R female so you can extend reach between outlets and equipment safely.

• Rated 50A max at 125/250V for up to 12,500 watts of load
• Compatible with many EVs (Tesla Model S/3/X/Y with appropriate adapter) and 50A RV shore power
• Maintains full amperage without voltage drop when used within rated length
• ETL-certified for electrical safety compliance

Is this extension cord durable and weather resistant for outdoor use?

Yes — the POWGRN cable uses a rugged STW jacket and materials selected for abrasion and corrosion resistance. It meets IP65-like protection expectations for outdoor conditions and is flame-retardant, making it suitable for seasonal exposure at campsites, driveways, and garages.

• STW-rated jacket resists wear, oils, and sunlight exposure
• Corrosion- and heat-resistant plug components for longevity
• Flame-retardant construction reduces fire risk from cable damage
• IP65-style protection guards against dust and water spray

What makes the design user-friendly and safe for frequent use?

The cord includes ergonomic features to make daily plugging and unplugging easier while protecting the cable and connectors. A larger insulated handle improves grip and helps you avoid bending the cable near the plug, and pure copper conductors optimize conductivity.

• Insulated, enlarged plug handles for safer, easier handling
• Pure copper conductors for reliable current flow and lower heat
• Flexible compound remains pliable down to -40°F for cold climates
• Grip storage strap included to keep the cord tidy and untangled

How should I match this extension cord to my equipment and stay safe?

Before use, verify both the outlet and the device accept NEMA 14-50 connections and that the circuit supplying the outlet is protected at 50 amps. Never exceed the cord's 50A rating, deploy it fully while in use to avoid overheating, and inspect plugs and jacket for damage before each season.

• Confirm outlet and equipment are NEMA 14-50 to avoid incompatibility
• Use only on properly fused 50A circuits and fully uncoil during operation
• Check for physical damage; do not use if plugs or jacket are compromised
• Store indoors when not in use to extend service life

Who is this for: The POWGRN 10 ft NEMA 14-50P to 14-50R extension is intended for EV owners and RVers who need a short, dependable extension to reach a compatible outlet without downgrading circuit capacity. It's well suited to homeowners adding a temporary 50A charging or shore power solution, RVers docking at crowded camp pads, and anyone who needs a rugged, cold-tolerant cable with easy-grip handles and ETL certification. If you require a different length or a different plug type, check outlet compatibility first to ensure a safe connection.
