Not every campground pedestal matches your RV's power cord, and that mismatch can leave you without power when you are ready to set up camp. An electrical adapter is a simple and affordable solution that lets you connect to available shore power regardless of the pedestal configuration at your site.

Our selection of RV electrical adapters includes 30-amp to 50-amp adapters, 50-amp to 30-amp adapters, and standard household adapters for situations where only a 15 or 20-amp outlet is available. Before ordering, confirm your RV's shore power cord configuration so you select the correct adapter for your needs. Carrying more than one adapter is a practical habit that ensures you are covered at most campground setups.

What RV electrical adapters do I need for campground hookups?

The adapter you need depends on the amperage of your RV's shore power cord and the pedestal you're plugging into. A 30-amp RV with a TT-30 plug needs a 30A-to-50A adapter (often called a dogbone) to use a 50-amp pedestal, or a 30A-to-15A adapter to run off a standard household outlet for light loads. A 50-amp RV needs the reverse: a 50A-to-30A adapter when only a 30-amp pedestal is available. Always match the adapter to both ends of the connection before plugging in. Browse the full range of plug options in our RV plug adapters collection.

Are these RV adapters safe for continuous use?

Yes, the adapters in this collection are rated for continuous shore power use within their listed amperage. The important caveat is load management: a 50A-to-30A adapter does not give your rig 50 amps of power, it limits you to the 30-amp source. Running two air conditioners, a microwave, and a water heater simultaneously on a stepped-down adapter will trip the pedestal breaker. Check your RV's total amp draw against the source before connecting. For surge protection and monitoring, pair your adapter with hardware from our RV electronics collection.

What is the difference between a dogbone adapter and a plug adapter?

A dogbone adapter has a short length of cable between the two ends, which reduces strain on the pedestal outlet and your shore cord. A plug adapter is a rigid one-piece unit with the male and female connectors back-to-back. Dogbones are preferred for daily campground use because the flex protects both connections; rigid plug adapters are lighter and easier to store for occasional use. Both types appear in this collection, and the listing for each product specifies the configuration.

Where can I buy RV electrical adapters with the right amperage rating?

You can order any adapter in this collection directly from United RV Parts, with 16 configurations covering the common 15A, 30A, and 50A combinations RV owners need. Each product page lists the amp rating, plug and receptacle type (TT-30, NEMA 14-50, 5-15), and cord length where applicable. If you are unsure which adapter matches your shore cord and pedestal, text or call our team at 817-984-1852 with your RV's amperage and we will confirm fitment before you order.
