RVGUARD 50 Amp 50 Foot RV/EV Extension Cord is a heavy-duty, weather-resistant NEMA 14-50 extension cable built to safely extend power between shore power or a Level 2 EV charger and your RV or electric vehicle.

When you need reliable 50A power at a distance, this 50‑foot RVGUARD cord combines a full 50-amp rating, rugged STW jacket construction, and user-friendly features like a disconnect handle and a power indicator. It's ETL/cETL certified and designed to work with 50A RV service and many Level 2 EV charging setups that accept a NEMA 14-50 connection. The cord ships with storage accessories to keep it neat and protected when not in use.

How does this extension cord handle outdoor and campground conditions?

The cord uses a durable 6/3+8/1 gauge STW jacket engineered to resist water, abrasion, and UV exposure typical at campsites and outdoor charging locations. The heavy-duty construction reduces heat buildup and wear from repeated plugging and coiling. ETL/cETL certification verifies it meets recognized safety standards for performance.

  • 6/3+8/1 gauge STW jacket for durability and weather resistance
  • ETL/cETL certified for recognized safety compliance
  • Proper conductor sizing to limit voltage drop over 50 feet

Will this work with my 50A RV and my EV like a Tesla?

This extension features standard NEMA 14-50P (male) and NEMA 14-50R (female) connectors, matching common 50-amp shore power outlets and many Level 2 EV charging adapters. It supports the full 50-amp service used by most large travel trailers and can be used with EV charging equipment that accepts NEMA 14-50. Always check your vehicle or charger's manual for compatibility and charging requirements.

  • 50A male (NEMA 14-50P) and female (NEMA 14-50R) connectors
  • Rated for 6250W at 125V and 12500W at 250V
  • Suitable for 50A RVs and many Level 2 EV charging setups

What user-friendly features make this cord easier to use and store?

The cord includes a molded disconnect handle that protects the cable and your fingers while plugging or unplugging; this reduces strain on the connector and improves safety. A built-in power indicator light shows when the cord is live, removing uncertainty at night or in poor visibility. It also comes with a storage bag and strap for tidy stowing in your RV bay or garage.

  • Molded disconnect handle for easier, safer plug removal
  • Power indicator light to confirm live connection
  • Storage bag and plastic strap included for neat organization

How durable is the plug, cable, and overall construction?

RVGUARD designed this cord for repeated outdoor use by combining sturdy connectors with a resilient jacket and quality internal conductors. The 6/3+8/1 conductor arrangement minimizes overheating and ensures long-term performance under the loads typical of RV appliances and EV charging. Proper care—avoiding sharp bends and storing dry—will extend service life.

  • Robust molded connectors resist cracking and loosening
  • Appropriate conductor sizing to reduce heat under load
  • Weather-resistant jacket protects against abrasion and moisture

Who is this for: The RVGUARD 50 Amp 50 Foot Extension Cord is intended for RV owners, travel trailer users, and EV drivers who need a dependable, weather-ready 50A extension to bridge distance between power sources and vehicles. It's best suited to people who want a heavy-gauge cable with safety certifications, an indicator light for quick checks, and simple storage solutions for seasonal or frequent use.
