ELEGRP 50 Amp to 15 Amp RV Adapter Cord

ELEGRP's 50 Amp to 15 Amp RV adapter cord converts a 50A twist-lock inlet to a standard 15A household plug, giving safe short-term power from a 125V outlet to your RV or trailer.

When you need to power an RV, camper, generator or trailer from a regular home outlet — for charging batteries, running lights, or prepping the fridge before a trip — this compact dogbone adapter bridges the gap between a NEMA SS2-50R inlet and a NEMA 5-15P outlet. It limits output to 15 amps, so it’s intended for temporary, light-duty use rather than powering high-draw appliances simultaneously. Built with a weather-resistant STW jacket and 10 AWG copper conductors, the cord prioritizes durability and a secure twist-lock connection to reduce disconnection and moisture intrusion.

How does this adapter keep the connection secure on my RV?

The female SS2-50R twist-lock end includes a molded locking ring and a professional-grade locking structure so you can twist and lock the plug onto the inlet. That lock reduces loosening from vibration and helps keep out water and dirt compared with a straight-in connector.

• Twist-lock mechanism for a positive, vibration-resistant fit.
• Molded ring and ergonomic grip for easy turning and removal.
• Design helps resist moisture and reduces accidental unplugging.

Is this adapter rugged enough for outdoor and generator use?

Yes — the cable uses an STW-rated jacket and 100% copper 10 AWG conductors, providing flexibility, UV and flame resistance, and reliable conductivity in outdoor conditions. It’s sized and protected for frequent handling on campsites and around generators.

• STW jacket offers UV resistance and durability in varying temperatures.
• 10 AWG pure copper wire for better current carrying and lower heat.
• Ergonomic grips reduce strain and wear from repeated plugging/unplugging.

What power limitations should I expect when using this converter?

This adapter reduces the available power to 15 amps at 125 volts (up to 1875 watts). It’s suitable for charging batteries, running lights, fans, and small appliances, but it will not allow full 50 amp service or support multiple heavy loads at once.

• Rated output: 15A / 125V, maximum 1875W.
• Not suitable for full two- or three-phase 50A appliance loads.
• Use for short-term or preparatory power, not continuous high-demand operation.

How easy is it to use and carry for travel or storage?

The compact 12-inch length and dogbone design make the adapter portable and simple to stow in an RV compartment or tool kit. Textured grip handles on both ends make plugging and unplugging straightforward without tugging on the cable.

• Approximately 12 inches long — compact and travel-friendly.
• Ergonomic grips at both connectors reduce strain and extend cord life.
• Lightweight design fits small storage compartments and gloveboxes.

Who is this for: RV and camper owners, motorhome hobbyists, food-truck operators, and anyone with a 50A twist-lock inlet who occasionally needs to draw safe, limited power from a household 15A outlet or generator. It’s designed for temporary shore-power tasks like charging batteries, maintaining fridge temps, or running lights. Do not use as a permanent substitution for proper 50A service or for operating multiple high-draw appliances at once.
