Moochdocking at mom and dad's and have had zero problems after four months of use. I use two of these plus the RV issued power cable for a total of 75 feet. Using 20 AMP power from their house and have noticed NO difference using this set up versus 25 ft power cable when camping. No difference in power pull over 75 ft and 25, using these extensions. Granted only 20 AMPs you're limited but no difference in the power usage with the 20 amp using 25foot versus 75 foot.
