Nilight RV Power Adapter Cord 18-inch — 30A to 110V Adapter with 15A Resettable Circuit Breaker and Weather-Resistant STW Jacket

Nilight's RV Power Adapter Cord converts a 30A RV connection to a standard 110V outlet while protecting your rig with a built-in 15A circuit breaker.

When you need to plug a 30-amp RV into a common household 110V (15A) receptacle, this Nilight adapter provides a safe, sturdy bridge. It’s designed to keep essentials like refrigerators, small air conditioners, microwaves, and battery chargers powered from a 125V, 15A source, and it includes overload protection so you can reset rather than replace on minor trips above current limits.

How does this adapter make connecting an RV to a household outlet simple?

The adapter plugs a NEMA 5-15P (standard 110V household) into a NEMA TT-30R (30A RV) inlet, giving you a quick, no-modification solution when only a 15A outlet is available. With an 18-inch length and flexible 10 AWG stranded copper conductors, it reaches and bends easily without stressing the cable or connectors.

• Converts 30A RV inlet to 110V 15A household plug
• 18-inch cord for convenient reach and routing
• 3 × 10 AWG stranded copper wires for reliable conductivity
• Ergonomic grip handle for safe insertion and removal

What protection does the built-in circuit breaker provide?

The adapter includes a factory-installed 15A circuit breaker that trips when the draw exceeds safe limits, preventing overheating or damage to connected equipment. Instead of replacing fuses, you can usually press the reset button after correcting the overload source, restoring power quickly.

• 15A resettable breaker for overload prevention
• Push-to-reset button for fast recovery
• Stops excessive current before cable or appliances overheat

Is this cord durable enough for outdoor and RV use?

Nilight built the adapter with an STW jacket and flame-retardant, heat-resistant PVC sheath that stands up to outdoor exposure, bending, and abrasion. The connectors and cable are ETL-tested for safety, and the material resists wind, rain, snow, and rough campsite surfaces.

• STW jacket plus heavy-duty PVC sheath for weather resistance
• ETL-rated construction meeting recognized safety standards
• Flexible yet rugged — resists cracking and wear in cold or heat

What appliances and loads can I run with this adapter safely?

The adapter is rated for 125V and 1875W when used on a 15A circuit, which supports many small to medium RV appliances but not full 30A loads simultaneously. It’s ideal for charging house batteries and running single, lower-draw devices such as a refrigerator, microwave on low cycles, or a small air conditioner if the total draw stays under the 15A limit.

• Rated 125V, 1875W on a 15A circuit
• Suitable for fridge, battery charger, microwave (limited duty), and small A/C within 15A
• Not for continuous full 30A loads — monitor combined draw

Who is this for: This Nilight adapter is for RV owners and campers who frequently encounter only standard household outlets at parks, friends’ driveways, or home storage areas and want a safe, portable way to power essential RV systems. It’s also useful for anyone who values a resettable breaker and a weather-resistant cable that simplifies temporary 110V hookups without rewiring or permanent changes to an RV’s shore power.
