RVGUARD 50A-to-15A RV Power Adapter with 15A Overload Protector, LED Indicator, 10/3 Copper

RVGUARD Overload Protector 50 Amp to 110 Volt adapter is a heavy-duty RV power adapter with a built-in 15A circuit breaker, LED power indicator, and durable 10/3 copper construction to safely convert shore power for low-draw appliances.

When you need to plug a 50A shore pedestal into a standard 15A household outlet—or safely power small RV loads from a 120V source—this RVGUARD adapter provides a compact, code-tested solution. It converts a NEMA 5-15P (15A) input to a NEMA 14-50R (50A) inlet while protecting your 15A circuit with a manual-reset overload breaker and a visible power indicator. Built to withstand outdoor use, the cord uses thick 10/3 copper conductors and an UV-resistant jacket for long-term reliability.

How does the overload protection work?

The adapter includes an internal 15A circuit breaker that trips if the connected load exceeds 15 amps, preventing the household circuit from being overloaded. After correcting the cause of the trip, press the reset button to restore power—no tools required.

• Auto-trip at loads above 15A to protect the source circuit
• Manual reset button for quick recovery once the issue is fixed
• Clear LED shows when shore power is present
• Designed specifically for RV loads, not for EV charging

What are the electrical specs and safety certifications?

This adapter is rated for 125 volts and up to 1875 watts, wired with full 10/3 gauge copper to carry current reliably. RVGUARD submits the completed product for third-party testing, and the adapter is ETL listed to the applicable U.S. standards, which is a stronger safety assurance than parts-only certification.

• 15A NEMA 5-15P (male) to 50A NEMA 14-50R (female)
• 125V, 1875W capacity with 10/3 pure copper conductors
• ETL listed as a whole product for verified compliance
• LED indicator confirms incoming power at a glance

Will this adapter hold up outdoors and everyday RV use?

Yes—the housing and cable are made for outdoor conditions. The conductors are 100% copper and the exterior is a flame-retardant, UV-resistant PVC jacket that resists sun, moisture, and abrasion typically encountered at campgrounds and storage locations.

• Molded plug and socket for a snug, weather-resistant connection
• Heavy-duty jacket protects against wear and sunlight exposure
• Solid copper wiring reduces heat and voltage drop under load
• Compact form factor for easy storage in an RV bay or garage

How should I use this adapter safely and what are its limits?

Use this adapter to run low-draw appliances, maintain battery chargers, or power interior lights from a 15A household outlet while parked. Do not use it for EV charging, for devices requiring a full 50A service, or where local electrical codes prohibit adapters—always verify power needs before connecting.

• Intended for RV, camper, and travel trailer 50A inlets only
• Not rated or recommended for electric vehicle charging
• Do not exceed 15A from the source; stagger appliance use as needed
• Check campground or home outlet ratings before plugging in

Who is this for? RVGUARD's 50 Amp to 110 Volt Overload Protector is made for RV owners, seasonal campers, and trailer hobbyists who need a safe, certified way to tap a standard 120V outlet for low-power RV needs. It's ideal for those who want visible power confirmation, ETL-verified safety, and durable construction for outdoor storage or short-term campsite use. If you require full 50A service or are charging an EV, choose equipment designed for that purpose instead.
