This made a perfect way to adapt my 50 amp Fifthwheel to 30 amp for hookup to my Westinghouse iGen4500dfc portable generator

No change, it works great.

by: Charles 04/26/2024

The adapter fits well into the RV. It appears to be very sturdy. Utilized it with a 25 ft 30 amp extension cord and plugged it into the 30 amp outlet in my shop and worked as expected. The small indicator light on the adapter worked as expected and will come in handy and perhaps save a few steps rather than going inside the camper to run the microwave to confirm you have 120 service. The unique red color may make finding it among other adapters easier.

It has met all of my expectations. Worked well, the angle reduces stress on the main outlet as well as cord

@Charles Fantastic to hear! Happy camping.

by: Leslie 07/14/2023

Fast shipping and it fits snugly. I had it plugged in for a few hours and no temperature change. The 90 angle doesn't look to put stress on the connection either. Sticks out about 5.5", which is about 1/8" less than the 50A cord. The threaded ring is a little thinner than the factory 50A plug, but hopefully that will hold up.

Fit the plug perfectly. Doesn’t seem overly robust so won’t rate a 5. It seems good but not excellent.

by: Daniel 08/07/2025

Exactly what I needed, quick delivery and d $40 less than local stores.
Suggest making products available at camper dealers

by: Steven 10/04/2025 One Year Later

It's just what I needed to hook up to 30amp service without having to use my big heavy 50 amp cord when 50 amp isn't available. The adapter is well constructed and works good and saves me a lot of effort.

by: Clayton 11/18/2025

Found item needed for a reasonable price, arrived quickly.
Very pleased and will shop here again!

by: Arthur 07/26/2025

Very happy with 50a to 30 a adapter. Well made quality adapter

by: G 09/16/2022

It fits and works. It will be such an ease because the 50 amp cord weighs a lot and is so bulky.

by: Michael 10/11/2025

Works well, I will look forward to using it when only a 30A service is available.

Dragging out the 30' 50A cable is heavy and a pain when you are camping with only 30A available. This solves that problem. Now I just get out the 30A extension cable which is much lighter and easier to manage. The fit of the connector is spot on and the threaded collar screws on perfectly. It's definitely worth the money.

by: David 04/07/2025

I was very surprised by the speed of delivery. I order it Friday and received it on Saturday.I bought this same adapter three years ago and it worked well until last year. Apparently this is pretty common for adapters to breakdown.

by: Andy 08/22/2018

Works great, design makes sense. Our 28 ft front bedroom toy hauler from ATC with a built in 5.5 Onan is set for 50 amp. But our use is usually more than covered by 30 amp. So dragging out that very heavy cord is not necessary with this product.

by: Brandon 09/26/2023 One Year Later

Works like it should. No problems. My only complaint with the product is that the red color fades fast in the sun. It is plugged in while it sites at my home in Michigan. Only real time I use the dog bone. But I didn’t buy it for its color.

by: William 09/05/2025

Perfect for my application. Received Product in a timely fashion.

Great piece of equipment when you only have 30 amp service - 30 amp cable is much easier to handle than the 50 amp

Cord has worked well. No signs of wear and tear yet.

Item was exactly what i was looking for, other sites would redirect you to similar product, cost was competitive, delivery was super fast with follow up making sure the item was received.

Using the 50 amp to 30 amp adapter any time I’m at a location that only has 30 amp available has taken the stress out of settling for a less than desirable spot. It is easy to store and install. The sun has bleached the top of the adapter but that is because I’m using it! Good product

Exactly what I needed. This adapter will save me from dragging out the heavy 50 amp cord when only 30 amp is available.

Hey Virgil, welcome back! We no longer carry the 724860519 Goodyear Endurance ST235/85R16 Radial Trailer Tire.

Comparing 50-Amp RV Service to 30-Amp RV Service, 4-Prong Plug Vs. 2-Prong
The Mighty Cord RV Power Cord Adapter, # A10-3050D90VP is used to adapt your RV's 4-prong 50-amp power inlet for use with a 30-amp 3-prong extension cord/Power Pedestal. A 50-amp plug has four prongs with two of them providing 50-amps of power each. But the 30-amp RV service with 3-prongs only has one prong of power, one power wire from the 50 amp is not used. The big difference to note between 50-Amp RV service and 30-amp RV service is that the 30-amp RV set-up provides a nominal 3,600...

Can You Use 30-Amp Surge Protector on 50-Amp RV

Do Both Hot Legs on 50-Amp Side Of The Adapter # A10-3050D90VP Get Power From 30-Amp Receptacle?
Yes, both hot ends of the Mighty Cord RV Power Cord Adapter # A10-3050D90VP are able to receive power when connected to a 30-amp connection. This ensures that both the circuits are able to get power since they stay split inside the camper.

How To Get Power To Specific Circuit Breakers With A 50 Amp Panel On 30 Amp Service
Your 50 amp breakers should each have a single hot line running to them so there wouldn't be an adapter to send power to both lines. The output of the shore power in this case would only be 30 amps so you'd be more likely to blow the circuit if you did somehow power both lines. The # A10-3050D90VP is only going to power one line so the only real way to power all of your outlets would be to have those circuit breakers in line with the 50 amp main circuit breaker that is getting power so...
