25' 30 amp extension cord

I did a quick search on this forum and didn't find the answer so I hope someone out there can help as I am not an electrician. What is the difference between all the 25' 30 amp extension cords out there? The prices seem to range any where from $30 to over $100. All are 10 gauge wire. What else is there I should be aware of and look for?
thanks

Not sure of the actual reason.  I am guessing that some of the reason has to do with where the cord was manufactured.  China versus USA, also the more expensive ones have nicer ends.

It was many years ago now, I bought two generic 25 foot long 30 amp "extension" cords that I carry in our PC all the time.  I bought them cheap at Menard's, but today they are more pricey.  At the time, everywhere else the cords were a lot more money.

I have used one 25 foot extension cord one time in all these years.  It was in Black Canyon Of The Gunnison NP camp ground because the power peg was too far away from where we setup on the parking pad.  I know there are limits as to how long a 30 amp cord should be.  Maybe the PC supplied 30 foot plus two additional 25 footers is bad practice, but I have them just in-case.  They are surely better than using 15 or 20 amp extension cords in a pinch.

Simple, quality, wire type (how many strands of what kind of wire... Fine stranded copper is best, but more expensive), flexibility of "rubber" in the cold... But most of all... Because they can.

My guess is that the one big difference is the markup by United States retailers !!!!  All these power cords are virtually similar. The only big difference is the usefulness of the end connectors to suit individual connection situations.

If you trace back Furrion, Camco, Epicord, Weekender, Conntek etc, you will find their parent companies all list Taiwan, Vietnam, Hong Kong or China. None lists the USA as the manufacturer or as the location of any factories. All they list is that they have offices in the USA.

For example Conntek, usually a highly rated power cord, lists it's "offices" in Franklin, Wisconsin. But it shows that Conntek ISI is a fully owned Asian manufacturing company with factories throughout the the Pacific Rim that specializes in exporting a variety of electrical power connection products. My bet is that Conntek manufactures very similar products under a bunch of different brand names.

We have all become "trapped" by a world economy.

One big difference is material. Aluminum or Copper.
This plus type of insulation affects the flexabiity.
Any 10 GA copper from Amazon should work fine, but a good 30 amp female to 15 amp male for times when no 30 amp outlet is available, like at home.

Agree, I use a Conntek 14355 RV Pigtail Adapter Household Male Plug To 30 Amp Locking Female Connector along with a 50' 10 gauge 120v "household" extension cord.   Makes hookup to a standard outlet very easy although you can't use it to run A/C simply because standard home outlets are mostly only 15a.
