How Many Watts Does a Fan Use

Fans are used for many purposes in a household. You may have ceiling fans, cooling fans in different appliances, exhaust fans, and others. Since these fans work for a considerable time, the power consumption increases. So, how many watts does a fan use? Let us find out as it will help you to reduce your power consumption.

Many factors determine the power consumption of a fan, including the size and diameter of the fan, the motor specification, and the running time. Also, there are different types of fans; some are more energy efficient than others. We will also discuss the following;

  • How many watts does a ceiling fan use?
  • How many watts does a box fan use?
  • How many watts does a 20-inch box fan use?
  • How many watts does a standing fan use?

Key Takeaways About Fan Wattage

  • The average fan wattage is 39.3W when running on high and about 6.9W on low setting.
  • If your fan runs for 12 hours a day, then it makes it about 471Wh on average.
  • Using a Jackery solar generator helps you save a considerable amount of energy and money. These generators are cost-effective, noise-free, and noise-free hence a great experience.

How Much Power Does a Ceiling Fan Use?

As we discussed, how many watts a fan uses depends on the fan's size, speed, and motor. The same concept stands for ceiling fans too. A medium-sized ceiling fan consumes 31.1 watts when run on high and 3.6 watts on low. However, the most common average comes out to be 33W. The highest wattage of a ceiling fan generally is 99.8 watts.

What Size Generator Do I Need for Fan When Off-Grid?

Solar generators are the best option to power your fans in case of a power outage and for off-grid Power. The biggest reason to favor solar generators is that they do not use any fossil fuel hence zero fuel cost. They rely on the energy from the sun, which is free. Also, they are noise-free, fumes-free, and low maintenance. Therefore, they are a breeze to use.

So what size of generators do I need for fans when off-grid? It depends on the power consumption of your fan, which we have discussed above. Once you figure out the wattage of your fan and the average runtime, you can decide the size of the generator.

How to calculate the hours: Working time = Capacity Wh * 0.85 / operating wattage of your device

For example, assuming the power consumption of your fan is 33 W.

A Solar Generator 1000Pro Working time will be 1002Wh * 0.85 / 33 w = 25.8 hrs.

The above-mentioned supported hours are calculated on the 85% capacity of the generator, so we are multiplying the capacity by 0.85. We expect some loss of efficiency during transmission and operation. Hence the numbers mentioned above are accurate estimations.

FAQ about Fan Wattage

How much electricity does a fan use in 24 hours?

Total power consumption(Wh) = Running watts x operating hours.

If your fan uses 33 watts and works 12 hours a day, your electricity usage is 396 watt-hour if it uses 75 watts, then 900 watt-hours, and so on.

How much Power does a fan consume?

It depends on the fan's type, size, motor power, and operating hours. On average, a ceiling fan uses 33 watts, a box fan uses 100W, tower fan can consume

54W, while a standing fan can eat up to 40 watts.

How much electricity does a ceiling fan use?

A ceiling fan uses 15-90 watts of energy on average; however, it also changes with the fan's speed.


We have discussed the power consumption of different types of fans and how to calculate your fan's power consumption. Also, the best way to contain your power cost is to use solar power generators.
