Extension cord is heavy gauge and appears to be well-made.

After a year, the cord is still in great shape. I expect it to last for many years to come.

Love dealing with etrailer! Their support is the best I’ve encountered. The RV power extension is perfect and I have used it in several occasions now. They are my resource for all RV parts. Quality and good prices.


Cord came quickly and nicely packaged. Plugged it into my camper, into a pigtail, and into my generator. Worked perfectly.

No problems. Plug it in, and it works. Nice, heavy duty product.

Great to work with. |I had ordered wrong cord and they sent Return label right away and helped me order the correct cord.


Great service and fast!


Perfect OEM replacement


As advertised. Extremely fast processing and shipping.


Would love to give a 5 star put at this time i can not, Was about to cancel this order until i got a Email saying it was finally shipped Put decided not to cancel even thro i had to borrowed a 30 amp ext cord,Part A10-3025E was out of stock,the most important part i needed in the whole shipped,to late to used my new 30 amp Mighty core rv power cord extension this year,But i am shore it will work great next year. The rest of my order was Great.. the triple ext cord,the sewer adapter,the pop up container.and the septic treatment worked great,Now the Question is would i prefer a friend and would i order again from Etrailer,com.The Answer is YES They just have to let you no when a product is out of stock,The Product are great at a great price


Works as advertised.


The perfect adapter and extension cord for my RV. My rig is set up for 50 amp service however, this is not always available in a number of campgrounds. 30 amp is more common, therefore I can run most everything in my trailer!


Any product that i have bought in the past has been exactly as i wanted, the light harness i bought for my Jeep works well the light bulbs are not very bright, but easily fixed


just what I wanted. Quality 30 amp extension cord


This 30 amp cord is just what I needed. High quality, coils up every time without an issue.I it's way better than I expected for the price.

Great quality . I have used the extension many times with no problems
Eric L - 09/03/2017


A 30 foot power cord came with our travel trailer. I had a feeling that this might be short in certain instances. I have needed the extention cord about 50% of the time. Glad I got it! Works great, and very flexible.


Bought this for my camper about a year ago no problems with the cord. ordered and received in a couple days. will use etrailer again.


I use the cord with the existing cord as an extension cord. It allows me to camp further away from the power supply. Also, when running on generator, I can move it further away. Great product & great price.

by: delivered as promised, great service. Will follow up with a review on product once it is used a number of times.


This cord is exactly what I needed. Now I am set. Another great purchase from etrailer.


Heavy duty 30 amp extension cord that was exactly what I needed! Shipped super fast!


Just as described in perfect condition and shipped very quickly! I will order again from etrailer!!


This product is just what we needed our cord was not quite long enough for where are camper set now with this extension we have plenty cord for our needs


I had a hard time finding this product. Etrailer delivered thanks!


Its a good cord. Nice and flexible and very durable


needed a longer cord for the motor home. This cord was perfect for the job.


Just what I needed at a decent price.

should last almost forever.

  • Will Mighty Cord RV Power Cord Extension # A10-3025E Fit With Tighter Beam Clearance to Generator
    I sent your picture to my contact at MightyCord and told him what you are trying to do and while he didn't give me an exact dimension he said you'd have plenty of clearance to fit the male side of the Mighty Cord 25' RV Power Cord Extension # A10-3025E for your application.

  • What is the Voltage Drop of the Mighty Cord 30 Amp RV Extension Cord - 50'

  • What Cable Insulation Designation Do Mighty Cord RV Extension Cords # A10-3025E & # A10-3015EH Have
    I spoke to my contact at Valterra, he confirmed that both the Mighty Cord RV Extension Cord - 30 Amps - 15' Long # A10-3015EH and the Mighty Cord RV Extension Cord - 30 Amps - 25' Long # A10-3025E have a cable insulation designation of STW.

  • Recommended 30-Amp Components For Trailer
    We do not offer a kit for a 30 amp circuit as you requested but we do have the items you mentioned as separate items I have attached a link to our product page for the 30 amp items we offer. For a power inlet I recommend part # 277-000138. For a power cord I recommend part # A10-3025E.

  • 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 Power Adapter for 1985 Mallard Camper Into House 110v
    Your 1985 Mallard Camper has a 30 amp power supply. The Mighty Cord RV Power Cord Adapter Plug - 30 Amp Female to 15 Amp Male - Round # A10-1530ARDVP or the Mighty Cord Dog Bone RV Power Cord Adapter - 30 Amp Female to 15 Amp Male - 12" - Black # A10-1530BK are the adapter you will need. You can use the Power Grip RV or Household Power Cord Extension - 125V - 15 Amps - 30' Long # CAM55142 for an extension but it will be best to use the larger 30 amp extension cord like # A10-3025E.

  • Recommended RV Pigtail 30 Amp and 125 Volt
    We do have power cables that meet your 30 amp and 125 volt criteria, however we do not have a 36 inch option for length. I'm not sure why that length is needed, but if you can use a longer cable it is actually more cost effective to use a manufactured length. If you need a precise 36 inch long cable, I recommend you customize a cable to that length using Epicord RV Power Cord with Handle 25' Long Pigtail # 277-000144 and the Mighty Cord Replacement Hardwire RV Plug - Female End # A10-R30VP....

  • 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...
