  • Yes, our adapter is certified of whole product by ETL, not like other brands only plug or cord had listed by UL.

  • The main difference between UL and ETL listed products is that ETL doesn't create its own standards for certification. UL develops standards that are used by other organizations, including ETL.

  • No, it just convert the plug type to fit for your RV.

  • This adapter allows you to run the refrigerator in the trailer prior with home power to departure and stock food for camping.

Indoor only?!?! Junk product
Junk product. Sold as an rv generator cord but the warning states not rated for outdoor use. Indoor use only. Really generator rv adapter for indoor use? Don't know about you but that's just lazy ul approval. It has a ground so it can be approved but they're too lazy or cheap to get it
