Exactly what I ordered. Looks great getting ready to use this weekend. More to come.

Delivery was fast and website was easy to navigate. I am pleased with the rv extension cord for my camper!! A++++


I bought this extension cord to supply power to my RV in while it's parked in my driveway. I shopped around for similar cords, and eTrailer had the best price. It arrived promptly on the promised delivery date, and I put it to work right away. It is solidly made, and I look forward to using it for many years to come. It is exactly what I need. The folks at eTrailer continue to provide me with outstanding personalized service. eTrailer is my go-to place for all my RV accessories.

This cord is still in constant use keeping my camper powered. I remain very pleased with this purchase and eTrailer is still at the top of my list for my camper needs.

Very nice power cord and it was delivered quickly.

It works fine
Peggy - 09/04/2021


This power cord solved my problem as soon as I connected my camper to it. I live in Florida and was using a heavy duty 12/2 extension cord to run my camper at home. When the weather got hot the extension cord could not handle the current. I received my A10-3050E today and it is running everything just great. Thank you for your great service and product.

Still working as good as the day I got it. Thank you

So far very satisfied with this product


As always, the products from Etrailer are satisfactory and well made. Shipping is timely and quickly done, I received my order a day ahead of schedule. I have ordered several items from Etrailer and have never been disappointed.


Great cord!!


This is a true extention cord for our 30amp RV. There have been several times we could have used this in the past so it will be handy. The product is high quality and exactly as pictured. The customer service we received from eTrailer was excellent when one of the items we ordered was out of stock!


Excellent service, excellent product. For RVers, fits nicely with most weather-proof surge protector covers.


As always whenever I need something important for my RV the folks at etrailer always comes throughwhen needed


Service as always prompt with up to date info

  • What Does Mighty Cord RV Power Cord Adapter Connect To?
    The Mighty Cord RV Power Cord Adapter # A10-3050HDVP simply plugs into your RV's 50-amp, twist-lock power inlet to give you a male plug which connects to a 30-amp extension cord such as the Mighty Cord # A10-3050E. I've added links to video reviews of both parts for you to take a look at.

  • Looking for 30 Amp to 30 Amp RV Power Cords
    We have a lot of 30 amp to 30 amp basic RV power cords and extensions. How long of a cable are you looking for? We have numerous sizes from 10 foot, # A10-3010EH, to 50 feet, # A10-3050E. I have included a link to the options for you. There are many different kinds of 30 amp plugs and receptacles. The ones in the list below range from 110 Volts to 125 volts. There are also twist lock style plugs/receptacles. For those you would plug in the cable and twist to lock it into place. So in short...

  • 50-Foot RV Power Cord Rated for 30-Amp Service
    The Camco part # CAM55333 that you referenced is an adapter that has different male and female 3-prong connectors on its two sides. One side is a male 30-amp twist-lock and the other is a female 30-amp receptacle. For a 50-foot extension cord rated for 30-amp service we offer the items shown on the linked page, including Might Cord # A10-3050E which has a female connector like the female one on the Camco adapter and a mating pronged male connector on the other end.

  • Is it Okay Use Two 30 Amp 25' long Extension Cords to get to 50' Total
    Yes it is okay to use two of the Mighty Cord 25' RV Power Cord Extension part # A10-3025E to acheive the same effect as the Mighty Cord 50' RV Power Cord Extension part # A10-3050E. They both use the same 10 gauge wire so it will not cause you issues. The positive to this is that you aren't trying to wrap up 50' of heavy cord. The down fall to this is that you now have an additional connection point and it could possibly come unplugged.

  • Recommended Cord Reel for Mighty Cord RV Power Cord Extension
    The Mighty Cord 50' RV Power Cord Extension - 125V - 30 Amp # A10-3050E will work just fine with the Cord Reel - 150' - 11" Diameter # PT53FR, which will be durable enough to handle the 10 gauge cord on the Mighty Cord. The Cord Reel # PT53FR is made with a heavy duty impact resistant housing, so it's designed to hold up to the rigors of traveling in the cargo hold in your RV or trailer.

  • Availability of Very Long RV Extension Cord
    If your RV uses a 30 amp plug, we have a 50 foot long extension that would work great for you, part # A10-3050E. If you need a 50 amp plug, we offer part # CAM55195 that's 30 feet long, which you could plug into # CAM55194 for a total of 45 feet long. However, be aware that the longer your extension cord gets, the more voltage drop you'll experience. At greater lengths, this drop may prevent certain equipment that needs high start-up voltage to operate like refrigerators or A/C units from...

  • I need Some Accessories for my Airliner Scout Lite and a Tongue Weight Scale
    For the etrailer Tongue Weight Scale for Campers and Utility Trailers part # e99044 you will have no issues with an inaccurate reading with that little bit of difference in heights. The jack wheel may be a permanent wheel or it could be removable they do design them both ways. The only way to be sure is to hook it up to your jeep or support the weight of the tongue and lower the trailer until it comes off of the ground so you can check. If it does come off I would recommend removing it...
