How much power does a swamp cooler use?

A swamp cooler, or evaporative cooler, typically consumes between 100 to 500 watts of electricity, depending on its size and efficiency. This is significantly less than traditional air conditioning units, which can use 2,000 watts or more. The actual power usage can vary based on factors like the cooler's design, the ambient humidity, and the temperature of the environment. Overall, swamp coolers are an energy-efficient cooling option in dry climates.
