RVGUARD 50 Amp 15' RV/EV Extension Cord — NEMA 14-50, STW Jacket & ETL Certified

RVGUARD's 50 Amp 15 Foot RV/EV Extension Cord is a heavy-duty, ETL/cETL-approved 14-50 extension designed to safely extend power for 50A RVs and Level 2 EV charging.

Whether you're parked at a campground, working in the driveway, or charging an EV at home, this 15-foot STW power cord bridges the gap between your appliance and a NEMA 14-50 outlet. Built with a rugged 6/3+8/1 gauge jacket and a molded 14-50P plug plus 14-50R receptacle, it supports up to 6,250 watts at 125V or 12,500 watts at 250V. The cord includes user-friendly features like a power indicator light, a molded disconnect handle, and storage accessories to keep the cable organized when not in use.

How durable is the cord for outdoor and travel use?

The RVGUARD extension cord uses an STW-rated jacket and heavy-gauge conductors to resist abrasion, moisture, and repeated connection cycles. It’s ETL and cETL tested for safety and consistent performance in typical RV and outdoor settings.

• 6/3+8/1 gauge construction for reliable current flow
• Weather-resistant STW jacket suitable for campsite conditions
• ETL/cETL certification for inspected safety standards
• Molded plugs that minimize stress at connection points

Will this extension work with my electric vehicle or RV?

The cord is wired to the NEMA 14-50 specification, making it compatible with 50A RV shore power pedestals and common Level 2 EV charging setups. Many EVs that accept a 14-50 inlet — including various Tesla models with the right adapter — can use this extension for charging at appropriate power levels.

• NEMA 14-50P male plug to 14-50R female receptacle
• Rated 50A: up to 6250W (125V) or 12500W (250V)
• 15-foot length to extend reach without excessive slack
• Compatible with 50-amp RVs, travel trailers, and Level 2 EV setups

What safety and convenience features are included?

RVGUARD designed this cord with practical touches to make everyday use safer and easier. The molded disconnect handle helps prevent strain and reduces the chance of damage when unplugging, while the built-in indicator light confirms when power is present. Storage accessories keep your cord tidy between uses.

• Molded disconnect handle protects plug and fingers during removal
• Power indicator LED shows connected power at a glance
• Includes storage bag and plastic strap for neat packing
• Durable connectors and jacket reduce wear from frequent use

How should I store and maintain this extension cord?

Store the cord dry and coiled to avoid kinks or crushing; use the included strap and storage bag to keep it protected from dirt and UV exposure. Inspect plugs and jacket before each use for cuts, melting, or loose connections, and avoid running the cord under rugs or through doorways where it may be pinched.

• Coil loosely and secure with the supplied strap
• Keep in the storage bag when not in use to prevent damage
• Check connectors and jacket for wear before each connection
• Avoid sharp bends, heat sources, and prolonged UV exposure

Who is this for? This RVGUARD 50 Amp 15 Foot extension cord is aimed at RV owners, travel trailer users, contractors, and EV drivers who need a short, reliable way to extend a NEMA 14-50 connection. It suits anyone wanting a portable, certified solution with clear power indication, easy handling, and compact storage — especially when frequent hookups and outdoor durability matter.
