Anyone add power winders to their rigs after market. If so any advice

There isn't any more resistance(heat) in the cord whether it's wound up or laying out.
I asked because I saw this on another forum:
Electrical engineer here-
The amount of inductance from an extension cord coiled loosly pretty negligable.
Heat does not increase resistance an appreciable amount in copper wire, either. If that were the case we wouldn't need circuit breakers as all circuits would be self-limiting.
The only reason to watch out for a coiled extension cord is the heat. The rule of thumb that I would use is to derate the amperage rating of the cord by 25-50% when coiled, or just bump to the next size larger cord. For a #12, coiled cord I would keep the continuous amperage draw below 10 amps. You can just touch it with your hand once in a while to see if it gets warm.
The danger is from the insulation on the wires melting and causing a fire as the wires arc together.
