Video Transcript for Mighty Cord RV Power Cord Adapter Plug Review

Hi everyone. Aiden here with etrailer. Today we're gonna be taking a look at this Mighty Cord power adapter for your RVs. This is going to be a great way to take your 30 amp plug and adapt it to a 50 amp outlet. So let's say you've got a rig like us. We've got a 30 amp power cord going to our receptacle, and here at the shop, we don't have a 30 amp outlet.

We only have a 50 amp. So if we wanna be able to use that plug, we can just plug into this adapter, plug it in the wall, and get the same 30 amps that we're used to by plugging into the 50 amp side. Now what that means for you is if you're at the campsite, your shore power, maybe one of the outlets isn't working, like the 30 amp just isn't working, but the 50 amp is. Plug this in, and plug into the working outlet, and you can get that power to your rig like you'd expect. Let's check it out.

So the end of our cord and our adapter we'll just join together, and then that can go into our 50 amp. (adapter clicking) And then we've got power to our rig. I don't love this style of adapter because it's really small and this design does have a tendency to sometimes overheat based on what we've been told by customers before, and it does put a little bit of weird stress on the outlet sometimes, and maybe even your cord, especially depending on how much excess cord you have hanging down, how heavy it is. It's just not going to be as nice, and could result in wearing down the cord or the outlet, or the adapter a little bit faster. Now, Mighty Cord does make other versions of this, though, that aren't just this small block, that actually have right angles, and in total are about 12 inches in length that are flexible and can move around.

I like those a lot better because they're higher quality, and do tend to put a lot less stress on the components. Now, this is definitely the more affordable option so if you're just looking for something basic that is still pretty small and fairly easy to use, then this can definitely fit the bill. But around the shop, we use the nicer ones because again, they just don't put as much stress on the equipment, and I think they tend to be a little bit easier to use, easier to get a grip on and unplug, because they often have little loops here to pull on when you're unplugging, whereas this just has some small ridges on there, which again, work fine, just not as nice. (lid clicking) That's really all there is to it. This really just comes down to picking out the right adapter for your rig, because this 30 amp isn't a twist lock.

It's just a standard one. So just make sure you've got the right connections and the right adapters for what you need. If you're looking for a way to get the power that you expect out of your campsite when maybe one of your outlets isn't working, then this can certainly fit the bill and give you that power that you used to having. Thanks for watching.

High quality,Very Heavy Duty. Now I connect to 50amp and don't keep popping breakers from using too many appliances at one time.


Just as promised. I have used more than once and have never been disappointed.


Pulled into a campsite that only offered 50 amp service my trailer is 30 amp so Boondock with this adapter will never happen again


I had need for this adapter a few weeks ago while camping and had to borrow one from the campground owner. Now, if a campsite only has 50 AMP outlets I will be able to hook up my 30 AMP plug right away without having to borrowing one.



Came in handy at a couple campgrounds. Their 30 amp was old and didnt provide enough power. Used the 50 amp outlet w/my adapter and had plenty power to run things.


Great communication and timely delivery of a quality product!!


Works well


After looking and looking online, I found exactly what I needed at etrailer. The ordering process was easy and the package arrived quickly. Thank you!


This product is great! I was at a campground where the 30 amp sockets were so worn out that I could not get any electricity for my motor home. The 50 amp sockets looked like new, so now I can plug into the 50 amp socket and plug my cable into the 30 amp on the converter and have electricity. Thanks


Great compact adapter...takes up a lot less space than a dog-bone. Seems great but haven't used it much yet.



This has been working great for me!


This is one of the best companies I've ever dealt with. I order all of my trailer parts from them. When I place an order, they send me constant updates, keeping me informed concerning the shipping date and whether or not an item has been back ordered. When I've called them for information, they have always been helpful. I fully recommend this company!


One side of the plug does not conduct electricity.

You mentioned that one side of the plug is not working. I wanted to ask what you plugging into?


I received the 50 amp to 30 amp adapter model (A10-5030 AVP). The product exceeded my expectations. Very heavy duty and real easy to handle it plugging in and removing.


It worked great! The trailer didn't go up in flames when I plugged it into the 50Amp, and I didn't get electrocuted either.


This is exactly what I needed. Works perfectly. etrailer comes through again. Fast shipping too.


Love Etrailer. Good systems for ordering and delivery. Everything I need for my rv at a fair price.


Looks good..exactly what I needed. We have 30 amp coach..needed an adapter in case we only have a 50 amp site. Price was better compared to others.


A quick easy way to adapt your 30 amp camper to today's 50 amp campgrounds. Compact easy to use and store.


Received quickly, but I won't be able to make sure it works until August, when I'll need it to hook up to a 50 Amp service. I gave it 5 stars in confidence of products I've already purchased from etrailer.


Haven't had a chance to use this yet but, good to have in my "just in case" bag.
As always, etrailer has good prices and fast delivery.


30 amp to 50 amp adapter


Needed item right away. Service representative made sure I would receive it very quickly and picked out the item by telling her what I needed. I have gotten several items from etrailer and plan to continue doing business with this responsive company


With this converter, I can set up my Camper at home. Thank you!


what is there to say it works great. The best thing about it is the option to use it on a 50 AMP situation.


Just what I was needing and at a great price. etrailer For The Win!


As described
