Video Transcript for Mighty Cord 50 Amp RV Power Cord Adapter Review

Jake: Hey guys. It's Jake 00:00:01 here with etrailer. Today we're gonna be taking a look at, and I'm going to show you some of the features, on this Mighty Cord 50-amp to 30-amp converter.This cord is going to allow you to convert your 50-amp plug or your 50-amp cord to give you extra length to get to a 30-amp hookup. The application in which this cable's going to help you the most is if you go to a campsite where you know they're going to have only a 30-amp hookup and you go there regularly and you're not wanting to carry around a 50-amp, because they are significantly heavier. This is going to be able to allow you to extend it from your camper or RV to the 30-amp hookup. Otherwise, it's going to be an extension that you can add on to your 50-amp service to get to a 30 if you need more length.If you have a plenty long 50-amp hookup, you can buy a shorter extender.

They're only about a foot, foot and a half long, like this one, that's going to convert your 50-amp to a 30. These are a little bit easier to store than this 25 foot cable.Let's go ahead and get it plugged in. It's going to hook up just like your standard 50 would. Line up your prongs, insert and twist to lock it in place. They have this threaded collar that you can twist on to keep your plug in place so it doesn't come removed.Your male end is going to be your standard three prong, 30-amp hookup, with two indentations here on the top you'll see.

Gives you a little bit more to pull from to be able to get it unhooked from your power source.What I like about this kit is it's simple. It's going to give you that conversion from the 50 to 30 with 25 feet of length, so it's going to give you what you need and more length.With all that being said, that's going to do it for a look at the Mighty Cord 50-amp to 30-amp conversion cable.

It's still cold up here, but this is just what I was looking for. How many times do you curse having to wrestle a 50amp cord when you're not going to run two AC's or other power hogs..... for that matter, too many parks still only have 30amp anyway. This is a nice, manageable size and weight. 349551

Excellent products along with a spot on company! 688217

I wanted a light weight 30a cord when I didn't need the full 60A at the campsite or in the RV parking spot. The cord is soft and pliable to coil, uncoil even in cooler temperatures. 667517

- A10-3050EDBK

I like it very much. Much lighter a flexable than the 50 amp cord. When I dry camp I can only run one AC unit anyway. Don't have to lug around the Bulky 50 amp cord. 665754

- A10-3050EDBK

Cord is 50 amp to the RV and 30 amp to electric post. Sure beats having to use an adapter. Great product and price though I could have used 5 more foot of cord. etrailer shipping great as usual! 637166

I ordered a 30 amp RV power cord with a 50 amp female connection to replace the heavy 50 amp cord.. i was impresses with how quickly Etrailer shipped the ordered product. This cord supplies ample current to my camper and is easy for me to handle and store. My only disappointment is the lock ring that I cannot get to screw onto the connection. That noted, I am very satisfied with the product and appreciate the quick response to my order. 589271

I like the increased versatility with this product. 526524

I ordered the power cable due to installing 2 Easystart in my AC Unit to reduce the power load on my Airstream Trailer. Last Sunday I final tested the system using the new power cable and running one ac unit with my honda 2000 generator. I ran it for 4 hours and the power cable never got hot or warm. This newer lighter 50 amp to 30 amp will make my setup easier. I only need the heavier 50 amp cable if I'm planning on using both AC units. Great product. 523329
