Cooler kitne watt ka hota hai? (What is the wattage of an air cooler?)

Household evaporative air coolers in India typically range from 100 Watts to 250 Watts. Personal coolers draw around 150W, tower coolers ~170W, and large desert coolers ~200W based on BIS IS 3315 standards.

Cooler 1 ghante mein kitni bijli khata hai? (How much electricity does a cooler use per hour?)

A 200-Watt Desert Air Cooler consumes 0.2 kWh (units) of electricity per hour. Running it for 10 hours daily consumes 2 units per day.

Cooler 10 ghante chalane par kitni bijli ka bill aata hai?

A 200W Desert Air Cooler running for 10 hours daily consumes 60 units per month. At an average tariff rate of ₹7.50/unit, it adds approximately ₹450 per month to your electricity bill.

How much electricity does an Air Cooler use compared to an AC?

Air coolers consume about 80% to 85% less electricity than air conditioners. While a 1.5 Ton AC consumes ~1,250 Watts, a Desert Cooler consumes ~190-200 Watts, saving over 300 units per month.

Does an Air Cooler pump consume a lot of electricity?

No. The submersible water pump in a household air cooler only consumes between 10 to 25 Watts. Over 85% of the cooler's power draw goes to the main blower/fan motor.

Why Actual Air Cooler Consumption Varies:

Evaporative air coolers consume significantly less power than air conditioners because they only run a blower fan motor and small submersible water pump.
Representative category wattages (150W Personal, 170W Tower, 200W Desert) serve as default industry benchmarks.
Calculated energy and cost figures represent estimates based on entered user assumptions and state utility tariff engines.

How Air Cooler Power Consumption is Calculated

An evaporative air cooler uses electricity for two components: the main fan/blower motor (~90% of total power) and the small submersible water pump (~10% of total power). Total rated wattage ranges between 100W for personal coolers up to 250W for large desert coolers.

Daily Energy (kWh) = (Total Wattage in Watts × Operating Hours) ÷ 1,000

Monthly Units = Daily Energy × 30 Days

Example: 200W Desert Cooler running 10 hrs/day = (200 × 10) ÷ 1,000 = 2.0 kWh/day = 60 Units/month
