Malxs 30A Generator to RV Power Adapter NEMA L14-30P to TT-30R — 12" 10AWG STW Cord, Outdoor-Safe

When you need to run RV appliances from a portable generator, this compact adapter provides a safe, code-conscious connection between a generator’s NEMA L14-30P 4-prong output and an RV’s TT-30R 30‑amp inlet. Built with a 12-inch STW-rated 10AWG cord and molded polyvinyl housings, the adapter is designed to stand up to outdoor use while keeping wiring simple and secure.

How does this adapter let my RV use generator power?

The adapter takes the generator’s 4-prong twist-lock output (NEMA L14-30P) and routes the required hot, neutral and ground conductors into an RV-style TT-30R female receptacle. It keeps wiring straightforward so you can power air conditioning, a microwave, and other 30A RV appliances from a compatible generator.

• Matches NEMA L14-30P male to TT-30R female for 30A, 125V circuits.
• 10 AWG copper conductors for consistent 30A performance (STW-rated).
• 12-inch cord minimizes voltage drop while keeping adapter compact.

Is the construction durable enough for outdoor and campground use?

Yes. The adapter is molded from heavy-duty polyvinyl with 100% copper contacts and a rugged STW jacket on the cord, giving resistance to heat, cold and general outdoor wear. It’s ETL-listed to industry safety standards for portable power adapters.

• Molded polyvinyl housings resist impact and moisture.
• 100% copper contacts for reliable conductivity and low heat buildup.
• STW PVC jacketed cord rated for outdoor temperature variation.

How do I connect and disconnect the adapter safely?

The adapter’s female end includes an ergonomic grip handle to make plug-in and removal easier and safer, reducing strain on the cord and connectors. Always confirm the generator is off and any breakers are open before connecting or disconnecting to avoid arcing.

• Ergonomic grip handle on TT-30R female reduces pull stress.
• 12-inch length keeps connections tidy and accessible near generator outlets.
• Recommended practice: shut down generator and open breakers first.

What compatibility and loading limits should I check before use?

Confirm your generator’s outlet is a NEMA L14-30P and that total RV appliance load does not exceed 30 amps (3750 watts at 125V). This adapter is intended for temporary, portable power setups and is not a permanent wiring solution.

• Works with generators that accept a 4-prong NEMA L14-30P plug.
• 30 amp, 125V rating — max 3750 watts continuous load at full capacity.
• Verify individual appliance wattages to prevent overloads.

Who this is for: RV owners, campers, motorhome users and anyone needing a compact, reliable link from a 4-prong portable generator to a standard 30A RV inlet. It’s aimed at people who want a short, durable adapter that’s easy to handle, meets safety listings, and supports typical RV loads for temporary power at campsites, tailgates or emergency backup scenarios. Remember to check your generator’s outlets and your RV appliance load before use to ensure safe operation.
