Very handy for loading up before a trip. Was in Canada last Summer and one of the Rv parks only had 115 service. The adapter came in real handy.


I bought this adapter to use with my 2000 watt inverter generator while camping without hook-ups.
Works great!


Adapter is working as needed but is showing signs of a beginning heat problem. It stays plugged in for weeks at a time but has not failed. I would buy again.


I purchased this plug so I wouldn’t have to use my 50 amp cord before converting to 110vac. Obviously this is the way to go if you have use for 110vac circuit. I will be upgrading my 110vac extension cord to 15amps.


This adapter is perfect and works great. I use it with a 20 amp, 10 awg power cord for off season RV mx. The 20 amp cord is much easier to move around compared to a 50 amp cord.
Thanks to All at etrailer! Keep up the great work!


Good product - fit prefect.


It's was exactly what my daughter needed for her camper so when home need too clean camper or what love the adapter would buy again


Good quality and straight forward useag e.



After continuous use for the last year the plug is still working great and holding up well.


The first time I plugged a cord to this connector SPARKS FLEW? This plug is defective. There is no short circuit in the camper and the cord is good. I was able to find a "dog bone" style corded connector.


Worked great as advertised right out of the box. Indispensable tool for any RV!



Still working as intended and have had no issues whatsoever. The adapter still looks like new and functional great!


Product came fast after I ordered it! I looked EVERYWERE for this type of plug but the quality and reviews couldn't compare !! Well worth the money ,very durable and I think it will last me a long time . I give a 5 star review very happy customer and a much needed part for my RV when at home , in the driveway !


This is quite handy when I don't need more than 20A. I can plug in easily in the driveway or use just 1 generator when boondocking. I don't have to mess with the heavy 30A cord.

The fit is fine. A plastic or paper cup over the power cord and covering the connection keeps it dry as well.

David N.


Just fine. Its as handy as can be.


I needed something for the winter months to keep my camper battery charged without using the heavy cords that supply my 50 amp service. This adapter works perfect.



I use it year round to keep my RV batteries charged and lets me use the RV lights. It lets me use a light power cord for these jobs, so I dont have to deal with the heavy cords that would ordinarily be used.


I have not used this yet but it fits perfectly and it seems very well made, as it has some heft to it. It will be invaluable for campsites where we don't need 50 amp service (or even 30 amp with a 30-to-50 amp adapter).



I am still completely satisfied with the items I purchased.


Excellent product, great for connection a extension cord to power my fifth wheel when you don't need the big bulky cord that comes with the fifth wheel.



Great! Works as planed


I needed this for fair camping because there are only 20 amp outlets. The way the outlet boxes are set up my adapter at the box would barely make a connection and i had to zip tie it to the fence because it was too heavy of a cord. With this I use a regular extension cord, it plugs right in, and isnt too heavy for the box that is poorly mounted on the fence. I try to get 50 amp sites, but this annual venue is a fair and all they have is patch work outlets to use. I recommend this at it stores easily in the camper and is ready to go with an extension cord for a quick 20 amp connection.


Very good service received from ETRAILER good product respect for it's customers (received part damaged in the transport to exchange without any problem and without expenses very responsible company despite miles and miles that separates us) Gaetan Quebec Canada

Thanks for the follow up everything is very good Gaetan of Québec


I purchased this 50 volt to 110 connector in order to plug in my trailer at our storage facility prior to leaving on trips. This provides sufficient power to fully charge my RV battery and to not tax my battery when I open/close my slides. I’ve used this connector for the past year and have been pleased with its performance. Connector works as advertised!


This is Great! Now I don't have to get that big heavy 50 amp cord out every time I want to put power to my travel trailer. That big cord is a real pain when I just want to have lights, etc. I went right out and put it on. Excellent! Another note: I just had a little accident pulling my trailer out (didn't put the steps in and I tore them off). I went to the dealer where I paid $36,000 for the trailer and paid $548 (with my discount). I looked up the same steps on and they are less than half. What is wrong with this picture? I looked at other things at etrailer and can't believe the difference in prices. I wish I knew about them before I bought the steps! I could use the money I would have saved. Highly recommend them. I paid about $20 at etrailer for a high quality electric adapter that I could not even find anywhere else. Similar adapters were all about $90. Thanks Guys. I will check with you first from now on.


Awsome product for using to keep battery charged while in storage instead of having to use the heavy 50 amp or 30 amp cords. Even with my battery disconnect switch turned to off, there is a drain on the battery so this is a convenient way to keep the battery charged and lights available when stored.


Like it, saves dragging out the big 50 amp cord when just needing to maintain battery level and run the fridge...

Jerry E.


Love this adapter, perfect for at home to keep refrigerator, batteries charged and use the lights... Must have for 50 ampers...


What can I say. This is just the ticket! The sun in the Southwest is brutal, and now I don’t have to leave my expensive heavy duty cord out in the sun all the time when the trailer is not in use.



Still doing the job as expected. Using it daily to keep everything in the fifth wheel charged and functioning.


I received my adapter very promptly and it is exactly what I needed, I will definitely use etrailer again!



It was exactly what we needed as temporary way to get a little bit of power to the trailer until we ran a 50 amp service to front of house for full power so I havent used it since but I keep it around just in case, thanks.


I have been purchasing items for some time now, from my new 5th wheel hitch to small items such wheel chocks and plug adapters. I have NEVER been disappointed,
all orders arrived on time, packeged securly, and work as avertised. I most certainly
will be a coustimer as long as I own ay type on trailer.


Female 50a connection would not mate w/ my power port connect on my 5er. Regular power supply line connects perfectly without any problem. Inspected the difference between the two connectors and appears this adapter internal contact points are preventing the union. First time I’ve ever had a problem with a product from etrailer and will continue to shop with them, just not for products of similar origin as this 50a adapter. This adapter is being returned for a refund.

  • Connecting 50 Amp RV to 15 Amp Outlet At Storage Facility for Keeping Batteries Charged
    Yes, we can help with that, there is an array of plug adaptors available. Without seeing the exact plug on your cord, I think what you need is the Mighty Cord RV Power Cord Adapter Plug, # A10-1550DAVP. This is a 50 amp female to 15 amp male adaptor. There is also the Mighty Cord RV Power Cord Adapter witha twist lock, # A10-1550DVP. This too is a 50 amp female to 15 amp male adaptor. I suggest using a quality heavy duty extension cord with these to minimize resistance. Please note...

  • Can I Power The RV Slides Of My Keystone Montana High Country 5th Wheel 2014 From My Home
    Yes, you will be able to open your rv slides with the Mighty Cord RV Power Cord Adapter Plug - 50 Amp Female to 15 Amp Male - Round, part # A10-1550DAVP. You will not have enough power draw to run everything in your 5th wheel, but it should be enough to power your slides and possibly some lights, while you are recharging your battery. I have included a video demo link below.

  • Does 50 Amp RV Connector have Three or Four Blades/Prongs
    There are a few different 50 amp style connectors. The ones for RV applications use the 240 volt twist lock style of 50 amp outlet (NEMA L6-50) a lot which has three prongs whereas the 120 volt style of 50 amp connector you are thinking of that has 4 prongs is the NEMA 14-50 and is commonly seen for electric ovens.

  • Adapter Needed To Connect to House Power On Car Hauler With 50Amp Twist Lock Connector
    The Mighty Cord RV Power Cord Adapter Plug # A10-1550DAVP is all you will need to connect to a standard household extension cord. This will allow you to run up to 15amps to your camper. We also have the dog bone style Adapter # A10-1550D90VP if you prefer to have the easy pull ring on the back of the connector.

  • Is There A Difference Between The Mighty Cord # A10-1550DAVP And # A10-1550D90VP
    No, the only differences between the Mighty Cord # A10-1550DAVP and # A10-1550D90VP are the lengths and angle of the connector. The # A10-1550DAVP is solely just the connectors with no cable and the # A10-1550D90VP just comes with a cable and 90 degree bend to help prevent the cable from getting bent while plugged into the RV. Most people prefer the # A10-1550D90VP because of the 90 degree bend so that's what I would recommend for your situation.

  • 50 Amp Twistlock Female to 15 Amp Male Adapter Recommendation
    Instead of using two adapter the part # A10-1550DAVP would be a better option as it goes from a 50 amp twist lock female to 15 amp male like you need. Of if you wanted a longer setup the part # A10-1550D90VP is 12 inches long and has a 90 degree elbow. For a straight connector we have the part # A10-1550DVP.

  • Can 50 Amp Female Twist Lock Plug Be Removed From Mighty Cord Adapter # A10-1550D90VP
    The 50 amp female twist lock portion of the Mighty Cord 90-Degree RV Power Cord Adapter # A10-1550D90VP is molded to the cord and can't be taken off (unless of course you were to simply cut it). The closet option we have to what you are looking for is the Mighty Cord # A10-1550DAVP. This isn't a 90-degree plug but it is just the 50 amp female twist lock outlet by itself with a 15 amp male plug on the other side. I have attached a short video review that you can check out as well.

  • Is it Okay to Convert a Female Plug on an RV to a Male Plug
    There really isn't any problem or concerns with swapping a female plug to a male plug of any amperage rating. You will of course ensure you follow the instructions for the plug that you decide on to ensure you've connected the correct wire to the corresponding plug attachment point to avoid any issues. For instance the Mighty Cord Replacement Hardwire RV Plug part # A10-P30VP would be a fine replacement for the Mighty Cord Replacement Hardwire RV Plug part # A10-R30VP. I have linked the...
