It was made in China. The connections are lightly copper plated and not a high % of copper. Makes me wonder what the wire looks like. Instructions say always store indoors. Makes me wonder if the exposed copper plug and pins will rust? It also says do not cover cord when in use to avoid over heating. Now I really wonder what they used for internal wiring.... I think I'll send it back. etrailer's service and quality is usually excellent and I have bought over a thousand dollars worth of items since 2022 from them and have always been more than pleased with what I received up until this item. I am sending this back. The company's customer service is just top notch and can't be beat.

I trust the products I purchase at etailer and this item is no different, top quality and in use as we speck!

I needed this adapter in case the campground I go to only has 50 amp service hookup. Etrailer had just what I needed and at a great price. Their website has great information on all their products and superb technical help on product review videos and customer help. You can’t do better than Etrailer when it comes to great service, fast shipping and excellent customer service.

I really do like this heavy duty power cord. It is a super value and is very easy to unplug the male end. Also it is very flexible even in cold weather. A great product for any camper who needs an extension to their RV. Thanks again for such great products from your company…you can’t go wrong with etrailer.com.



by:

This adapter is necessary for a camp site only have 50 Amp outlet while your trailer has only 30 amp plug. I have spent a lot of time try to find this one, but nowhere can it be found except on etrailer.com website. Note if your wire are 20 or 30 amps you don't want to load up too many devices/electric loads even if you are hooked up to a 50amp site. This is something I always carry with me while traveling.



by:

Since I only received it today, I've only had time to look at this adapter. Inspecting it I can say it appears to be well put together and should work well. I borrowed one on my last trip for running our AC unit and additional amps available made everything, even the cords, a lot cooler than the 30 amp cord would normally run directly connected to park power post.
Based on that experience I bought this one to allow the air conditioner run a lot more efficiently.
I would recommend this product to anyone looking for better electrical performance.



by:

Excellent construction



by:

The plug is exactly what I needed to step up to a 50amp. I was thankful I had it when running air conditioner non stop this summer. So many of these plugs burn up but this one is holding up!



by:

Went to a week end horse show and unable to use my air conditioning due to my plug not fitting their outlet. Contacted the people at etrailer and they solved my problem right away. This adapter fits my plug and now if I arrive at a campsite with 50 amp rather than 30, I am golden, and now I can stay cool!



by:

Being new to the travel trailer community, I have found that there are always necessities that are a must to have on board. This adapter for connecting a 30 amp power converter to a 50 amp electrical service fits the bill where a 50 amp power source is the only service available. E-trailer could provide the adapter for a more reasonable price and more quickly than the other provider I researched.



by:

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.



by:

Best price, quick delivery (even using economy). Exactly what I needed to avoid having to rewire the existing outlet. A welcome addition to my class C
toolbox.



by:

Superb product! It's been working fine for more than one year. I really appreciated the follow up etrailer.com did after product purchase to ensure I was satisfied. I'd shop no where else for my RV needs.



by:

Excellent quick service, available to answer questions and knowledgeable with all products



by:

As always customer service and products rate at a very high level. Fast shipping too! Thanks for always being our go-to for our RV parts and supplies!



by:

Does what it is supposed to do. Handy to keep in the trailer incase you are at a campground with different amperage.



by:

I didn’t receive this. I received a faucet instead. Still waiting on the correct irder
