The right angle comes in real handy. Also the 15A to 50A saves a step down with a 30A to 50A - two less connections. We use this a lot at dog shows where we only have a 20A outlet. Great quality.

Thank you etrailer. Product was easy to order and came on time. Carol at etrailer was the first to let me know it arrived which was nice as we are far from the road where UPS delivers. Product as advertised. Looking forward to having it when I need it.

  • Recommended Adapters for 50 Amp RV to Alternative Connection
    There are many adapters that can work for you but not the 20 amp to 50 amp. For a 15 amp to 50 amp, use the Mighty Cord RV Power Cord Adapter - 50 Amp Female to 15 Amp Male # A10-1550 or the Mighty Cord RV Power Cord Adapter Plug - 15 Amp Male to 50 Amp Female - Detachable # A10-1550DAVP. For the 30 amp to 50 amp conversion, you can use the Mighty Cord RV Power Cord Adapter Plug - 30 Amp Male to 50 Amp Female - Detachable # A10-3050DAVP or the Mighty Cord Dogbone RV Power Cord Adapter...

  • How Does SoftStartUp Plug-In Soft Start for RVs Plug Into 20 Amp Socket
    Hey Reggie, to use the Softstart Plug Soft Start part # SSR64FR in a 20/15 amp outlet you'd need a dogbone adapter like the part # A10-1550 to convert it to that plug size/style.

  • Recommended Adapter for a Portable Power Watchdog Surge Protector To Plug Into a Residential Outlet
    You're definitely going to need an adapter if you're planning on plugging the 50 amp Portable Power Watchdog Surge Protector item # HU87FR into a residential 15/20amp circuit. For a 15 amp circuit you would need to use the Mighty Cord RV Power Cord Adapter item # A10-1550. For a 20 amp circuit will need two separate adapters because we do not have one 50 to 20 amp adapter. The first part you will want is the Mighty Cord RV Power Cord Adapter Plug - 50 Amp Male to 30 Amp Female - Detachable...

  • Can You Chain Different Amperage RV Power Cord Adapters
    Yes, if you like you can chain together the Mighty Cord RV Power Cord Adapter - 50 Amp Female to 30 Amp Male # A10-3050FHVP with the 30 Amp Female to 15 Amp Male # A10-1530HVP. However, it would probably be easier to just go ahead and use the Mighty Cord RV Power Cord Adapter - 50 Amp Female to 15 Amp Male # A10-1550.

  • Recommendations for 50A Service to 30A and 15A Services, and a Secured Surge Protector
    We definitely have some parts you can use for your application but none of them come in an all-inclusive kit. For a 50A to 30A service I recommend the Mighty Cord # A10-3050FHVP. For a 50A to 15A service I recommend the Mighty Cord # A10-1550. Please note when you are pulling power from pedestals that are rated for less power than your camper you'll need to keep track of how much power you're using so you don't overload the pedestal. I've attached a link to a helpful article about power...

  • RV 50Amp to 110v Home Power Adapter and Extension Cord Recommendation
    If I'm understanding you correctly, you'll be able to use your standard outlet at your home using an adapter like the Mighty Cord # A10-1550 , but you won't be able to use a standard extension cord . Using a household extension cord with an improperly small wire gauge can damage the cord and/or your RV's electrical system. Instead, there are a variety of extension cords available that are designed for RV use. 30-amp RV extension cords typically feature 10-gauge wire, and 50-amp cords usually...

  • Parts Needed to Connect 50 Amp Trailer Inlet to 110 Volt Power
    Thank you for the photo as it was very helpful and we do have exactly what you need to connect the 50 amp inlet on your trailer to the 110 volt on your house. Since there isn't a single adapter you will need two different parts, though using them is very easy. You will start with the Mighty Cord 90-Degree Detachable RV Power Cord # A10-5025ED90, which you will simply plug into your trailer's inlet. Then you will use the Mighty Cord Dog Bone RV Power Cord Adapter # A10-1550, which will...

  • How To Connect a Trailer with 50 Amp Service to a Honda Generator
    I am not sure which Honda Generator you have but the Mighty Cord Dog Bone RV Power Cord Adapter part # A10-1550 will work for you if you have a 50 amp service on your trailer and a 120 volt outlet on your generator. That said, most generators use a twist lock connector and if that is the case you will want to use the Mighty Cord Generator Adapter part # A10-G30450VP instead.

  • Connect 50 Amp Service Airstream RV To 15 Amp Outlet For Storage Charge Of Battery
    For use with a 50 Amp SmartPlug RV Power Cord, such as # SM86FR. I recommend the Mighty Cord RV Power Cord Adapter, # A10-1550. Connect your SmartPlug Power Cord to the RV as usual, but then plug into the Mighty Cord adapter for making connection to a 15 amp outlet when in storage.

  • Adapter Options to Connect 220 Volt RV to 110 Volt Outlet on Campground Power Source
    It really just depends on the style of 220 volt outlet you need. If it's a 50 amp style you'd want the part # A10-1550. If it's a 30 amp twist lock style you'd want the part # A10-1530DBK. I also attached a link to a page that has all of the different styles of adapters we have that would plug into a 110 outlet like you need.

  • 50 Amp Motorhome Powered by Grounded 110-120v Outlet
    Great questions. You will need to determine that your lights, tv, and fridge run off 110v/120v power. Many systems run off 12v power for lights, TV, and there are even a few refrigerators that run off that power. The adaptors are already in most RV's to make sure when you plug into shore power, all the other conversions. are made within the power distribution and converter box. Because you are looking for 50 amp connection through a 110v ground, you can use adapters but it doesn't...

  • Recommended 50 amp Surge Protector and Power Monitor for RV
    There sure is! You'll need the Portable Power Watchdog Surge Protector # HU87FR which is designed for the 50 amp power service your motorhome has, and uses bluetooth to send real time watt/volts/amp usage to your phone. Chances are your friends house doesn't have a 50 amp outlet for you to plug into, so you'll need an adapter to plug into a 30 amp outlet # A10-3050FHVP or into a 15 amp outlet with # A10-1550. Keep in mind when plugged in like this only half of your RV electrical panel...

  • Can I Use a 50 Amp Female to 30 Amp Adapter to Plug My RV Into a NEMA 6-50 Outlet?
    Hello Bill, I'm really glad you wrote in. You are on the right track wanting to use the power you already have in your garage, but the Mighty Cord Adapter # A10-G30350VP is not going to be the one you need. It is made for a 30-amp twist-lock generator outlet, and your NEMA 6-50 is a different 250V connection. You definitely do not want to try adapting that directly to your RV, because sending 240V to RV circuits or appliances that are designed for 120V can damage them. If you have a...

  • Can An Extension Cord Be Used with the Mighty Cord Dog Bone RV Power Cord Adapter
    I do have an option for you but I called Mighty Cord and they do not recommend that you use an extension cord with the Mighty Cord Dog Bone RV Power Cord Adapter part # A10-1550. If you choose to use an extension cord anyway then you would still be limited to 15 amps which would not allow you to run much in the trailer. The best option for you would be to have a 50 amp service installed at your home as this would then allow you to use a dedicated 50 amp power cord like the Mighty Cord...

  • What Material Are the Pins On the Mighty Cord Dog Bone RV Power Cord Made Of
    The Mighty Cord Dog Bone RV Power Cord Adapter part # A10-1550 has pins which are made of brass. The reason they are more silver in color than the yellowish color you are accustom to is because they have nickle plating which helps prevent tarnishing and discoloring.

  • How to Check if the Mighty Cord Dogbone RV Power Cord Adapter # A10-1550VP is Working Properly
    The best way to tell if the Mighty Cord RV Power Cord Adapter # A10-1550 is still functioning correctly would be to simply plug it in. If you don't think it is the adapter then I would try running some tests on the products that you are plugging in the adapter to make sure they are functioning properly. I don't have access to how the adapter is wired, but if it were malfunctioning I would not try to repair it on your own. If anything were not repaired correctly then that could result in...
