50 amp and 30 amp Progressive EMSUpdated 15 hours ago

You can use the 50-amp Progressive EMS for any trailer or motorhome, whether the RV has a 30-amp or 50-amp power cord. Simply put an adapter on the EMS as needed to plug into any lower-amperage power outlet.

You can use the AIR GEAR Nickel-plated Power Adapter Set-50 amp set (50 to 15 & 50 to 30) for this purpose. The adapters give you the ability to plug the 50-amp EMS into any power outlet (15-amp, 30-amp, or 50-amp) as you wish.

You can't plug a 30-amp EMS into a 50-amp campground power outlet. That would overload it. Only owners with a 30-amp RV power cord should purchase the 30-amp version of the Progressive EMS.
