Use as shore power routing cable to and from Victron Multiplus nverter
Size: 50-Foot, Style: Standard End
I cut the ends off this and used it for extending in the original 30A shore circuit to and from my power center to my 3000W Victron Multiplus inverter. Very flexible and easy to run. It was a bit dicey to remove the black outer support material without injuring the conductors - used a table knife. You want to leave a little cabling on the ends so that you might use them for other purposes. For example, to bench test the Victron Multiplus. Per foot it was less expensive than other options and worked better IMHO.

Glad I bought this one
Size: 25-Foot, Style: Standard End
There were other less expensive options but I'm glad I bought this one as it's a brand that I recognize and it seems heavy duty and well-made to me, and the cable feels just like the one coming out of my RV. I used this extension cord on a recent ten day trip for extra reach to a generator for running various appliances, including the air conditioner. I checked it periodically for any signs of overheating and it never felt abnormal at all to me. Just my own experience and opinions here, yours may differ. Thanks and good luck!

Great price, excellent product!
Size: 30-Foot, Style: Standard End
The Camco Power Grip 30-Ft 50 Amp RV Extension Cord has been a fantastic addition to my RV equipment. It offers both reliability and convenience, making my camping experience so much better. One of the standout features is the robust construction. The cord is heavy-duty, yet flexible enough to maneuver easily, even in tight spaces. The 50 Amp rating provides ample power for my RV’s electrical needs, ensuring that all my appliances run smoothly without any issues. The Power Grip handles are a brilliant touch, making it easy to plug and unplug the cord without straining my hands. The design is well thought out, and the bright color ensures that the cord is always visible, reducing the risk of tripping or other accidents. I also appreciate the weather-resistant coating, which provides extra durability and protection against the elements. It’s held up well in various weather conditions, from rain to intense sun, without any signs of wear or degradation. Overall, the Camco Power Grip 30-Ft 50 Amp RV Extension Cord is an excellent investment for any RV owner. It combines durability, ease of use, and reliability, making it a must-have for a hassle-free camping experience. Highly recommended!

The right length
Size: 30-Foot, Style: Standard End
Well made and heavy duty. It is an odd length but that’s what I wanted and needed. 50 ft. Too long and 20ft. Just not long enough . 30ft. Gives me the length that I can use and not have to try and stretch it and gives me a bit of slack and no tension in the run.
