I haven’t used it yet, but it’s lighter than I thought, which is good. The cord seems to be very well made and the team at etrailer has been very helpful everyone I order something.
Thank you again etrailer and I’ll let you know how the cord works once I use it.


Excellent choice for 50 amp extension c ord.


etrailer has been great to deal with. they have a great product selection that are in stock.


Arrived in 3 days. I was 25 feet too short with the factory cable. This was the best cheaper option I could find. Well made extension cable. Has not over heated. Can't beat it for the price. Has blue lights built in to let you know it has power. I will definitely buy a longer version when I can. Thank you very much!


The product is great, we made a mistake and ordered the wrong one, we needed a female twist & lock connector on the cable and we received a straight plug. We order a receptible at the same time for our RV and it was a Twist & Lock , it was great and easy to install. When we got to the Cable it was ooooh It don't match. We assumed it would match but it didn't we were not careful enough with our order. This company is taking care of us


Sent me a text when order was delayed and gave me an option to switch item to comparable. Used etrailer many times. Great service. Products solid.


It worked well


This was quickly delivered. I am happy to s a y it is in time for my next camping rv trip!


Process to order and receiving item second to none.


I purchased this cord to enable charging our new Tesla from a dryer outlet. Nice, heavy 6 AWG conductors (8 AWG ground) that have good flexibility.


Seems to be a well made extension cord. I wish it had handles but you were all out of them. I expect I will not use it until this fall.


This is exactly what I needed. Good price and arrived quickly. etrailer is my go to place for many of my truck and camper needs


Received the item 50 amp 25ft power cord today as stated when I purchased the item. Very satisfied.


Least expensive I have seen this 50 amp cord. It arrived at my house two business days after I ordered it with free shipping. Works great.


Fast delivery and good products


Product is Extreme high quality. Just what I ordered


The cable was delivered as advertised!




Exactly as advertised. Great service, fast delivery, great product selection and prices.
