How does this cord support RV and EV charging?

This POWGRN extension provides the standard NEMA 14-50P (male) to 14-50R (female) interface used by many RV shore power pedestals and Level 2 EV chargers. With a 50A capacity it can handle common high-demand appliances or electric vehicle charging without being a bottleneck.

• 50A maximum current, compatible with 125/250V systems
• Handles up to 6,250W (125V) or 12,500W (250V) depending on supply
• STW-rated jacket for industrial-grade durability
• Designed to match common Level 2 EV and RV power outlets

Is this cable durable and safe outdoors?

The cable jacket is engineered to resist abrasion, heat, corrosion and flames while meeting IP65 splash- and dust-protection expectations. Inside, high-quality pure copper conductors maintain conductivity and reduce heating under load; the assembly is ETL certified for safety assurance during normal use.

• IP65-rated weather resistance for rain and dust exposure
• Flame-retardant, heat-resistant outer jacket
• Pure copper conductors to reduce resistive loss
• ETL listing for verified electrical safety

What convenience features help daily use and storage?

POWGRN designed the extension with an insulated handle and extra grip space so you can connect and disconnect without straining the cord. The material stays flexible down to very low temperatures, and a built-in storage grip keeps the cable tidy when not in use.

• Insulated, oversized handle for easier plug removal
• Flexible down to -40°F to prevent cracking in cold climates
• Integrated grip for compact storage and transport
• 50-foot length gives wide reach between vehicle and pedestal

Will it work with my EV or campground hookup?

It fits equipment that uses NEMA 14-50 connectors, common on many RV parks and Level 2 EV setups (including many Tesla and aftermarket EV chargers). Always compare your plug and inlet types before buying to avoid incompatibility.

• Matches NEMA 14-50P (male) to 14-50R (female) standards
• Suitable for most Level 2 EV chargers and RV shore power pedestals
• Not universal—verify inlet and plug types before use
• Recommended for single-circuit 50A applications only

Who is this for: The POWGRN 50 ft 50A extension cord is aimed at RV owners, EV drivers using Level 2 charging who need extended reach, and anyone needing a rugged outdoor-rated power extension for high-current appliances. Choose this cable if you require a heavy-gauge, weather-resistant solution with easy handling and verified safety certification. If your equipment uses a different plug standard, confirm compatibility before purchase.
