Harbor Freight is advertising an electric pole saw and they say it is 1.5 horsepower and draws 7 amps.
Hm. 7 amps X 125 volts = 875 watts.
Hm. 875 watts ÷ 746 watts per horsepower = 1.17 horsepower.
Hm. 1.5 horsepower advertised ÷ 1.17 horsepower by the numbers = 128% efficiency.
Apart from mere "advertising hype" and pure "typographical error," can anyone see how they could make such a technical mistake in the arithmetic?
I've got a cortex vortex over how they could screw up this one, even using Occam's razor and just saying "it was a boo-boo."
I've been a little off my stride lately, but that one kind of leaped out at me. I know I'm going to feel like an idiot when someone points out
my error in thinking.
