Power Usage by Size

• Small (Bedroom Units): 50-80 watts

• Medium (Living Room Units): 80-120 watts

• Large (Open Spaces): 120-180 watts

Calculate Your Power Cost

Simple Formula:

1. Watts ÷ 1,000 = Kilowatts

2. Kilowatts × Hours Used = Units

3. Units × Rate = Daily Cost

Example Calculation

Using a 100-watt cooler for 8 hours daily at $0.12/unit:

1. 100 ÷ 1,000 = 0.1 kilowatts

2. 0.1 × 8 = 0.8 units/day

3. 0.8 × $0.12 = $0.096/day Monthly cost = $0.096 × 30 = $2.88

Power Usage Comparison

• Air Conditioner: 1,000-2,500 watts

• Evaporative Cooler: 50-180 watts

• Standard Fan: 45-80 watts

• Refrigerator: 100-200 watts

Factors Affecting Power Usage

1. Unit Size

• Larger units consume more power

• Match size to space requirements

2. Operating Duration

• Longer usage increases consumption

• Use timer functions when available

3. Fan Speed Settings

• Higher speeds use more power

• Adjust according to needs

4. Maintenance

• Dirty units work harder

• Regular cleaning saves energy
