RV Power Adapters

RV power adapters help connect your camper’s shore power cord to a compatible electrical outlet, making them worth checking before you head to the campground or park your rig at home. The right RV electrical adapter depends on your travel trailer, fifth-wheel camper or motorhome’s power requirements and the service available at your destination. Common RV hookups provide 30-amp or 50-amp service, and those connections have different plug configurations and electrical capacities. Match the adapter’s source-end plug to the power outlet and its RV-end connector to your shore power cord, checking electrical ratings rather than judging by appearance alone. A 30-amp RV connection supplies 120-volt power, while a 50-amp RV connection supplies two 120-volt legs. That difference matters, so follow your RV manufacturer’s guidance before choosing a camper power adapter. Check the campground’s hookup information ahead of your trip, too, so you know what connection to plan for before backing into your campsite. An RV shore power adapter changes the connection between compatible equipment; it does not increase the amperage available from the power source. For example, connecting a 50-amp RV to a 30-amp supply with an appropriate adapter means working within the lower service limit. You may need to run fewer appliances at once, especially equipment with a heavy electrical draw, such as air conditioners, electric water heaters and microwaves. A household outlet can impose an even lower limit, so confirm circuit capacity and manufacturer recommendations before connecting your camper at home. Switch off the outlet’s circuit breaker before connecting or disconnecting shore power, and inspect the adapter, cord and receptacle for cracks, scorch marks or loose connections. Keep connections dry and protected from standing water, and stop drawing power if you notice excessive heat or a burning smell. Don’t assume an RV plug adapter also provides surge protection or electrical fault monitoring; those functions require equipment specifically rated for the job. A little planning helps keep your campsite power setup matched to your rig and the hookup available.
