lol, champs are half the amperage, but its a quater the speed of a warn. A 20 foot pull still requires you to use double the amperage a warn would.
They use that motor because it is cheap, and then gear it down so it can still pull a half decent amount of weight.
The champ, mm electric, t-max, etc etc are all the same winch, picked off the shelf in china, with a different label slapped on it.
If you wheel in a group and dont use a winch often, go ahead.
I wouldnt run one recommend one, but thats just my opinion because of how many I've seen blow up.
Like anything manufactured in china, you do have a chance of getting one that will last, even the components in them are inherently low quality and not prone to last.
But to each their own. Just my 2 cents
