RVGUARD RV Adapter Cord 30A to 110V Surge Protector — 3600J, Resettable Breaker, LED Indicator

The RVGUARD Surge Protector 30 Amp to 110 Volt RV Adapter Cord converts a standard household 15A outlet into a 30A RV inlet while providing 3600 joules of surge absorption and built-in overload protection.

When you need to run fan, charge batteries, or power small appliances at home or in storage, this adapter turns a 15A (NEMA 5-15P) outlet into a 30A (NEMA L5-30R) inlet, offering a safer, more durable alternative to makeshift connections. Constructed with 10/3 gauge pure copper wiring and a flame-retardant, UV-resistant jacket, RVGUARD designed this cord with an ETL-listed full-product certification and an LED power indicator so you can quickly verify power status.

How does this adapter protect my RV’s electronics?

The cord includes 3600 joules of surge protection to absorb voltage spikes and a built-in circuit breaker that trips on overloads. These features help prevent transient damage and reduce fire risk from short-term faults or unexpected power events.

• 3600J surge absorber for transient voltage spikes
• Integrated resettable circuit breaker for overloads
• LED power indicator to confirm energized connections
• ETL-listed full-product safety verification

Will it work for charging batteries and running low-power devices?

Yes — this adapter is rated for 125V and up to 1875W, making it suitable for charging battery maintainers, running lights, small heaters, fans, and other low-power appliances. Use it to keep systems powered during storage or to run essential accessories from a standard household outlet.

• 125V / 1875W maximum load capacity
• Converts household 15A outlets to a 30A RV inlet
• Ideal for battery maintainers and small appliances
• 10/3 gauge copper conductors for efficient current flow

How durable and safe is the cord for outdoor or storage use?

The adapter uses heavy-duty, UV-resistant polyvinyl outer jacket and molded ends to resist abrasion, sunlight, and weather exposure. Pure copper wiring and ETL testing across the whole product deliver long-lasting conductivity and verified safety compliance.

• Molded ends reduce water ingress and strain on plugs
• UV-resistant, flame-retardant outer sleeve for outdoor exposure
• 100% pure copper wiring for corrosion-resistant performance
• ETL-listed as a complete product for consumer safety assurance

What should I know about installation and resetting the breaker?

Installation is plug-and-play: insert the 15A plug into a household outlet and attach the 30A RV inlet to your RV’s shore power inlet. If the adapter trips from overload, identify and correct the fault, then press the built-in reset button to restore power.

• Simple plug-in conversion: NEMA 5-15P to NEMA L5-30R
• Resettable breaker: press to restore power after fixing overload cause
• LED lets you see power status without tools
• Do not exceed rated 15A continuous load

Who this is for: RV owners and DIYers who need a safe, temporary way to power a 30A RV from a standard household outlet — especially useful for winter storage, maintenance, or campsite setups without a 30A pedestal. It’s aimed at buyers who prioritize verified safety (ETL-listed whole product), durable outdoor construction, and clear overload/surge protection without rewiring or permanent changes. If you require full-time RV pedestal power, use a dedicated 30A supply; this adapter is intended for intermittent, low-power use and convenience.
