Product seems to work as it should. Would like to have some sort of LED light on the plug that indicates it is connected to power. 851976

Was tired of pulling out that heavy and cumbersome 50amp cord and adapters when I’m plugging into a 15 or 30 amp service. This cord is very well constructed and much lighter than my 50amp cord. Would recommend this product for all you old fart RVrs out there.-. 765620

hooked up my two Honda 2000I generators to the house and works awesome... 744838

- A10-3050EDBK

It is just what I needed for 30 amp hookups. I now have a 30 amp and a 50 amp cable and don't need all the little go between gizmos. Also the 30 amp cable is a lot lighter than the 50 amp cable.. Got what I ordered in good time. 737475

- A10-3050EDBK

The product works well. I have a 50 amp rig and was looking for a way to not have to use adapters when only having 30 amp available. Also my 50 amp cord is heavy. If I only have 30 amp available, I use this new cord. What is most impressive is that I ordered this on a Wednesday afternoon and needed it by Thursday; Friday would be too late. The Sales Rep Julie told me she would expedite it to ship out that afternoon so I could have it by Thursday. I live outside Chicago. Julie made it happen and I did receive it on Thursday. Not only that, she e-mailed me to notify me that it had arrived. This is what I call excellent customer service. 719295

Needed an extension cord for some of the camping I do that has 30 AMP service. Product arrived 2 days after ordering. Haven't used it yet but will update once I have! Thank You etrailer for making my search so easy. 693194

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

- A10-3050EDBK

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

Excellent quality, works great! 516701

Cord works well. 464161

Great product came on time and hooks up just find now I don't have to use the heavy 50 amp cord at home much easier to handle Thanks 418616

High quality cable, delivered quickly - exactly what the doctor ordered. 374856

- A10-3050EDBK

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
