A 75 watt swamp cooler draws about 0.7 amps.
A swamp cooler that draws 3.5 amps uses 385 watts.
The 3.5 amp cooler draws uses about 5 times more electricity.

Just to make sure, you do know that a "swamp" cooler works best in dry conditions, like the desert, and doesn't work well in humid conditions, right? The water evaporates and creates cooling, so if there is no place for the water to go into the air -- like when it's close to 100% humidity -- it won't do much at all.

I'm just mentioning this since much of the USA is covered by high heat and humidity, so a "swamp" cooler might not help in many of those locations...

volts * amps = watts

watts / power factor = VA or apparent watts.

go figure - I would have labeled them backwards, but watts has been around too long.

If u are comparing 12V DC to 110V AC then power factor may be more of a consideration because it = 1 for DC. and less than 1 for AC

BEST can only be defined by u because there are trade offs for everything.
