How much power does an air cooler consume?

Air coolers offer a refreshingly sustainable and eco-friendly alternative to traditional air conditioners. Not only do they consume significantly less energy but also do not emit harmful gases or contribute to ozone depletion, thus reducing your environmental impact. Additionally, their portability and easy installation make for convenient cooling wherever you need it. 

As summer heats up and you keep those coolers humming all day and night, understanding their power consumption helps you estimate running costs.

Here’s what you need to know about calculating the power consumption of air coolers.

Air cooler power consumption: Calculate your air cooler’s wattage

The amount of electricity an air cooler uses can vary depending on several factors such as the cooling capacity of the unit, the fan speed setting, and the duration of use. However, on an average, an air cooler typically consumes anywhere between 100 watts to 200 watts of electricity per hour of continuous use. Generally, the electricity consumption of an air cooler is much lower than that of an air conditioner, which can consume anywhere from 1000 watts to 3000 watts per hour.

Additionally, some air cooler models come with energy-saving features such as automatic shut-off and timer settings that can help further reduce electricity usage and costs. Before purchasing and using an air cooler for your home or office, it is important to understand its rated power. This value reflects both the cooler’s cooling capacity and its energy consumption.

Higher-rated power generally indicates a more powerful cooler that will consume more energy and potentially lead to higher electricity bills. Now that you know what rated power is, let’s explore the different ways to determine it for your chosen air cooler.

To calculate the power consumption of your air cooler, the first step is to find its rated power. This information is usually specified in the product manual and will indicate both the cooler’s cooling capacity and its energy usage. If the manual or product label doesn’t list the rated power, you can calculate it yourself using the formula: Power Consumption (in watts) = Voltage (in volts) x Current (in amperes).

You can find both the values for voltage and current either on the product label or in the user manual that comes with the unit. Once you have the voltage and current ratings, simply multiply them together using the above formula to get the air cooler’s power consumption in watts. You can then convert the power consumption to kilowatts (kW) by dividing it by 1000 (1 kW = 1000 watts). And that’s how you can calculate the power consumption of your air coolers at home.

To know how much it adds to your monthly electricity bill, you will need to figure out the number of kilowatts consumed by the cooler in a month and multiply it by per unit cost of electricity in your area. Thus, you will get a good idea about which cooler is more energy efficient before you make the purchase.
