Air Cooler vs Fan
A fan only moves air; a cooler moves air and lowers its temperature. That extra cooling costs a little more electricity.

Cooling
A fan makes you feel cooler by moving air over your skin but does not lower the room temperature. In dry heat a cooler can make the air noticeably colder.
Electricity use
Small inverter and DC coolers in our list are rated 60–100 W. Larger AC coolers are 180–350 W. Check your fan's label to compare. See the electricity guide.
12 volt cooler vs ceiling fan
A 12 V cooler like Nasgas NAC-2100 DC 40 Litre Solar Air Cooler can run from the same battery during load shedding and gives real cooling in dry weather.
