Video Transcript for Mighty Cord 90-Degree RV Power Cord Adapter Review

A.J.: What's up, everybody It's A.J. with Today we're going to be checking out this 30-amp dog bone. It's going to have 30-amp twist lock on this side and a regular 30-amp plug on this side. And what this will be used for is hooking it right up to your rig where you got the 30-amp port here, and we'll run a 30-amp extension cord, plug it in outside to your generator or power support, and that'll get you power for your rig. Let's check it out.Going to line up the 30-amp sides.

You got the female end here, the male end. We'll just plug it in. Make sure you push it in there to get in there good, and then you can just twist it to lock in place. Now I can't pull it back out. It's locked in there, but additional security option here is you can tighten it up with this plastic tightener here that goes around the outside.

You can just twist this on, and that not only protects the connection but also just secures it in place. That way, if somebody trips over your extension cord on the outside, it's not going to rip this completely out and cause any damage. It's going to stay in. The worst that's going to happen is your extension cord's probably going to come unplugged.Using our 30-amp power cord, I'm going to plug that in the end here. And I want to note that it's got the loops, so that's really helpful when you go to pull them apart.

Just easier to have that to grab to pull them apart when you need to. Going to fire up our generator outside, and then I'm going to plug the cord in after that. With our generator running outside, we'll go ahead and plug the cord in.Looking at it plugged in, now the generator is fired up outside, you can see the light comes on at the end. This is an extra feature this one has over some of the other ones I've worked with. They don't all have that power light, so it's nice to know if this is plugged in and you're still not getting power, there's something going on in your rig.

We can turn on our lights. We got power in here. You can start to set up your campsite.Now there's a couple other variations of this cord. You can get this version that's not at a 90-degree angle. It still got the same 30-amp here and here. It's got the twist lock, but it doesn't have the light. It still has that extra cord so that it doesn't apply a bunch of stress on here when it's plugged in, so you still got that extra cord to give it a little bit of a give when it's plugged in. And if somebody kicks the cord out, it'll still detach, and you won't have to worry about it pulling out here or bending the prongs inside.Now the other variation is this adapter, and it's 30 to 30. Still got the twist lock, but there's no extra cord on there, so it is going to be pulling down here. If you have a heavy cord, it will be pulling down, but this is built pretty tough. It's got a rubberized plastic, so it will pull down on there a little bit, but it'll stay in place and lock in, so I don't think you really have the problem of it weighing down and bending anything. Again, this one does not have the power light, so if that's something you're looking at, I would just stick with the 90-degree one. Either way, they're all going to be good solutions for you, your rig at the campsite.Well, thanks for hanging out, and I hope this helped..

Mighty Cord RV Power Cord Adapter - 30 Amp Twist Lock Female to 30 Amp Male - 12" Long - A10-3030D90VP

Average Customer Rating:  4.9 out of 5 stars   (18 Customer Reviews)

Easily adapt your RV's 30-amp power inlet for use with a 30-amp extension cord (sold separately). Twist-lock female plug locks onto the power inlet. 3-Prong, male plug connects to a power cord for a hookup at home or an RV park.


Have had this plug for a year now. The only issue that I have had with this plug is the color fading from the sun. And that is to be expected. I have a 100’ 30amp cord that I have hooked up to this at home. Saves the cord from being bent all the time. I feel this is money well spent.


Fast service& the only place to find exactly what plugs & cords you need with too many different manufacturers for generators not using standard hook up. I love the website & products. Thank you!




Plug your 50A directly into any standard 15 or 20 amp 120V outlet
Can even run 1 AC unit.


High Quality Product, delivered on time.

After a year of full time use the Mighty Cord has been flawless. I recommend this product,

Lightning Fast Shipping. Great Prices. Perfect Communication. What more could you ask for. Parts arrived today, packaged in a very heavy protective box. I will buy from again for sure.
Thanks for the great experience.


Great fit, exactly what I was looking for. Have not had it long enough to say anything about longevity but it appears to be well constructed. I bought this to relieve the radius of the cable coming out of the side of the camper and give it a nice drop. I wanted to put my voltage protection up closer to the camper and away from the power box.

Only reason for 4 stars is that I tried to get the instructions for the product from the website and it says they’re not available. This confuses customers.


The product is as expected, great quality
and functions perfect. The service is very good as well.

Thanks etrailer

  • Can 2019 Lakota Living Quarters Horse Trailer with 30 Amp AC Unit Draw Power From Campsite
    30 amp service is very common at campsites. You'd have no problem attaching directly to the power supplies at the sites. Let's say you were at a campsite that only had 50 amp power supplied though, in this situation you could use the part # A10-5030FBK and you'd be set. Having more power than needed won't hurt anything. Your AC would only pull the amperage it needed.

  • Power Cord Options for 30 Amp Twist Lock Connector on Travel Trailer
    Yes, the Mighty Cord RV Power Cord - 30 Amps - 25' Long # A10-3025EDBK will work great for your application. It doesn't have the fancy fault lights that your current wiring does so you might consider using something like the Camco RV Power Defender Circuit Analyzer # CAM55310 as well which helps check for faults. You can use an extension like the Mighty Cord # A10-3025EH but I wouldn't go above this additional 25' of cord. If you anticipate needing more than that 25' of that initial connector...

  • 90 degree Dog Bone for Mighty Cord RV Power Cord Adapter
    What I think you are asking is for what is commonly referred to as a dog bone, something with a 90 degree angle for your power cord that fits the 30 amp Mighty Cord Replacement RV Power Inlet, # A10-30INBKVP. That would be the Mighty Cord RV Power Cord Adapter, # A10-3030D90VP. We have the Mighty Cord RV Extension Cord, 30 Amps at 15' in length, # A10-3015EH, or # A10-3025EH for 25' length and # A10-3050EH for 50'. Please note the linked product review video below.
