RVGUARD 50A-to-120V RV Adapter Cord with 3600J Surge Protection, LED Indicator & Reset Breaker

The RVGUARD 50 Amp to 110 Volt RV adapter cord is a compact surge-protected converter that lets you run low-power appliances from a 50A shore power while shielding your RV's electronics from voltage spikes.

When you need to tap house-style 120V outlets or shore power for lights, chargers and small appliances, this RVGUARD adapter converts a 50A inlet to a grounded 15A plug while adding surge and overload protection. Built with 10/3 copper conductors, a manual reset breaker and an LED indicator, it’s designed for campsite, garage or storage use where safe, temporary power is required.

How does this adapter protect my RV electrical gear?

The adapter integrates a 3600-joule surge suppression module that absorbs high-voltage spikes before they reach connected equipment. A built-in overload circuit breaker trips if current exceeds 15 amps, preventing overheating or wiring stress.

• 3600 joules of surge absorption to reduce damage risk from spikes
• Manual reset push-button breaker restores power once the fault is fixed
• LED power indicator for quick visual confirmation of live power

Will it let me use household devices with a 50A RV inlet?

Yes — the adapter converts the 50A (NEMA SS2-50R) female inlet to a standard 15A (NEMA 5-15P) male plug, supplying 125 volts and up to 1875 watts for low-draw appliances. It’s meant for temporary or occasional use, not to run multi-threaded high-draw 50A systems.

• Converts 50A shore power to a grounded 15A outlet
• Rated 125V and 1875W — suitable for chargers, lights, fans, microwaves within limit
• 10/3 gauge copper wiring for reliable current flow and reduced voltage drop

Is this adapter durable and safe outdoors?

The RVGUARD adapter uses heavy-duty materials and has been ETL tested as a complete product to meet U.S. safety standards. Its molded housing and UV-resistant, flame-retardant jacket protect internal copper conductors from weather, abrasion and routine wear.

• 100% copper conductors for lasting conductivity
• UV-resistant polyvinyl sleeve and molded connector bodies
• ETL listing for the assembled product, not just individual parts

How do I use the reset and indicator features?

If the adapter detects an overload, the built-in breaker will trip and cut power; after correcting the cause, press the reset button to resume operation. The bright LED shows when power is present so you can confirm feed status at a glance.

• Press the reset button after resolving the fault to restore power
• LED lamp indicates live input — useful for quick troubleshooting
• Simple plug-and-play design requires no tools for typical use

Who is this for: RVGUARD’s 50A to 110V surge protector adapter is aimed at RV owners, van lifers and boaters who need a safe, temporary way to power household-style devices from 50A shore power or a house outlet. It’s also useful for people storing an RV who want to keep batteries gently charged and equipment protected, and for anyone seeking an ETL-listed, durable adapter with surge and overload safeguards.

Note: This adapter is intended for temporary conversion to 15A circuits and for protecting low- to moderate-draw devices. Do not use it to bypass required 50A-rated systems or for continuous operation of high-current appliances beyond its 1875W rating.
