# How Much Electricity Does A USB Fan Use?

The table below depicts the amount of electricity used by various types of fans over the course of one hour.

In general:

• Over the course of an hour, ceiling fans use 0.0311 kWh of electricity at maximum speed.
• On maximum, box fans utilize 0.073 kWh of electricity over the same time period.
• On their highest setting, tower fans use 0.0565 kWh in an hour.
• Over the course of an hour, table / standing fans use 0.0425 kWh of power.

Now that we know how much electricity various types of fans consume in an hour, let’s look at how much they use over longer periods of time.

### How much electricity (kWh) fans use over various durations

Fans use 0.0393 kWh of electricity every hour, 0.3144 kWh per night, 0.943 kWh per week when left on 24 hours a day, and 28.3 kWh per month when left on 24 hours a day.

The table below illustrates the amount of electricity used by various types of fans each hour, night, day, week, and month in kWh.

Ceiling fans require 0.2488 kWh per night, 0.7464 kWh per day, 5.225 kWh per week, and 22.39 kWh per month on average if left running 24 hours a day, seven days a week.

If box fans run continuously, they consume 0.584 kWh every night, 1.752 kWh per day, 12.264 kWh per week, and 52.56 kWh per month on average.

Tower fans use 0.452 kWh per night, 1.356 kWh per day, 9.492 kWh per week, and 40.68 kWh per month on average when running 24 hours a day, seven days a week.

Expect to use 0.34 kWh per night, 1.02 kWh per day, 7.14 kWh per week, and 30.6 kWh per month if you run the usual table / standing fan 24/7.

We can now simply calculate the cost of running the various types of fans because most power companies bill per kWh.

## Is it true that plug-in fans consume a lot of electricity?

Fans, on the whole, don’t use a lot of energy. A DC fan, as opposed to an AC fan that runs directly on 110-volt alternating current from your wall outlet, is incredibly energy efficient, typically using less than a third of the energy used by older AC fans.

## How much does it cost each hour to run a fan?

Not at all. The cost of running a fan is fairly low. A common ceiling fan, for example, consumes 50 Watts. The expense of running more powerful fans (with wattages of 100W+) can be rather considerable.

The cost of running most fans (10W to 100W) ranges from \$0.0013 to \$0.0132 per hour. Even if you run a 100W fan at maximum speed for an entire day (24 hours), you will spend about \$0.32 per day.

First and foremost, we shall investigate how many watts a fan consumes. We can compute how much electricity a fan uses per hour, per day, per week, or per month using this information.

For instance, how much energy does a ceiling fan consume? A normal 50W fan consumes 0.05 kWh of power each hour. That’s less than a cent per hour with an average electricity price of \$0.1319/kWh (0.66 US cents, to be exact). If you ran it for a day (24 hours), the 50W fan would cost you \$0.16.

A ‘Fan Power Consumption Calculator’ can be found further down. Simply enter the number of watts your fan produces, and the calculator will determine how much it costs to run that fan every hour.

In addition, we’ve created a fan power consumption chart with computed operating expenses (per hour, day, week, and month) for fans ranging from 10W to 1000W.

Only two pieces of information are required to accurately calculate the running cost of any fan:

• What is the wattage of your fan? This is called as ‘running wattage,’ and it can be found on the fan’s specification sheet or label.
• What is the cost of electricity in your area? Obviously, greater power costs result in higher fan operating expenses.

Before you can use the fan cost calculator, you must first determine the wattage of your fan as well as the cost of electricity (cost per kWh).

Let’s have a look at how much power is used by fans:

## Is a fan less expensive than air conditioning?

Fans are less expensive to run than air conditioners and can be used instead of or in addition to them to save money. If you have a ceiling fan, turn it on at the same time you turn on the air conditioner. Cooler air is pushed down and over the bodies of everyone in the room.

## What is the most energy-intensive activity?

The Top 5 Electricity Consumers in Your House

• Heating and air conditioning. Your HVAC system consumes the most energy of any single appliance or system, accounting for 46 percent of the energy used in the average U.S. house.
• Equipment for television and media.

## Is it true that leaving the fan running wastes electricity?

By circulating air and providing a wind-chill effect on our skin, fans keep us cool. As a result, turning on your fans before leaving for work will not keep your house cool while you’re gone. They will just waste electricity in your home.

## Is it worthwhile to invest in power banks?

Since we are now using these gadgets longer than the battery capacity, power banks (or external battery chargers) have become a requirement for most of us to charge our mobile phones, gaming devices, computers, tablets, and other devices.

Power banks are made up of a certain type of battery housed in a customized casing with a special circuit that regulates current flow. The device can store energy to be used to charge an electronic device later. When you’re away from a wall outlet, having a power bank on hand is a great way to recharge or top off your gadget. These power banks work with a wide range of USB-charged gadgets, including cameras, smartphones, GPS systems, gaming devices, laptops, GoPro cameras, MP3 players, and even tablets. A power bank can charge practically everything that charges via USB at home.

## A 12 volt fan consumes how many amps?

Different 12-volt fans utilize different amounts of electricity. However, the low number of volts (12 volts) also means that the total amperage draw is low. Take, for example, the below-mentioned fan. This 12-volt fan produces 8 watts of power. We can calculate that the fan utilized 0.6 amps using our Volts x Amps = Watts calculation.
