Diffuser Voltage:

An oil diffuser is able to work with dual voltages of 110-volt and 240-volt supplies. Which means that we don’t need to worry about the voltage supply. For example, 

A diffuser used in the US most commonly has 110 volts and the diffuser in the UK does have 230 or 240 volts. But it is necessary to check that the voltage of the diffuser is appropriate according to the supply at home.

How Many Amps Does A Diffuser Use?

  • A diffuser uses amps that range from 0.35 amps to 1 amp.
  • Commonly a diffuser can draw the amperage up to 0.5 amps

Does the diffuser use a lot of electricity? 

No, the diffuser does not use a lot of electricity as when compared to the other appliances like electric kettle electric heaters they use a lot more electricity than the diffuser especially the electric lenses that heat the water consumes a lot of electricity. In the case of the typical power rating of the diffuser ranges from 6 Watts to 25 watts with which the most common being 12 watts. Hence we can say the electric kettles and the electric heaters do consume 10 times more power than the diffuser.

Comparing the diffuser with other electric appliances:

  • When it is compared to the small table fan it uses less than half the amount of electricity.
  • Compared to the TV it uses five times less electricity consumed by the TV.


An Essential oil diffuser is not a device that consumes a lot of energy. Typical 12 Watts diffuser can use upto 0.5 amps. But the diffuse is capable of using electricity when it is in. The diffuser uses less amount of electricity and the cost to run it is less when it is compared to the other electric appliances used in the home.
