Can You Plug a Humidifier Into a Power Strip?

can you plug a humidifier into a power strip

You recently bought a humidifier, but your preferred wall outlet is farther than expected. Now, you’re asking yourself, “Can you plug a humidifier into a power strip?”

It’s not advisable to plug a humidifier into a power strip. Also, avoid connecting the appliance to an overvoltage protector or multiple-output adapter. Doing so may increase the risk of fire, electrocution, or injury.

But what would happen if you plug a humidifier into a power strip? This post aims to answer that question and more.

Why You Can’t Plug a Humidifier Into a Power Strip?


Understanding the reason why you can’t plug a humidifier into an extension cord means knowing how the device works.

Humidifiers generally work by emitting mist. This vapor typically comes from a built-in container. The device’s heating element quickens the natural evaporation process of the water in the unit, turning it into a mist.

Poor placement of a power strip may make the extension cord catch the mist coming from the humidifier. If the extension cord catches the water vapor, it may result in a short circuit. 

What Happen if You Try to Plug a Humidifier Into a Power Strip?


Oftentimes, plugging a humidifier into a power strip isn’t a cause for concern. For instance, the extension cord may not catch the mist if it’s fairly far from the unit.

But aside from the risk of the power strip getting wet, plugging a humidifier into an extension cord can increase the risk of an overloaded power strip or fire. This scenario may still occur even if the power strip is quite far from the device.

In particular, some humidifier brands warn their users not to use extension cords for their products. The high amount of electricity pulled by the humidifier, especially if it’s a high-power model, may cause an unwanted increase in heat in the cord.

Practice power strip safety and proper humidifier usage by reading the product’s owner’s manual before use. If an instruction manual isn’t available, think about plugging the unit directly into a wall outlet instead.

Can a Humidifier Be Plugged Into Extension Cord?


It’s still possible to plug a humidifier into a surge protector or extension cord. But you should avoid this action as much as possible.

Take note that some humidifiers require about 220 volts to run. Plugging the device into a 110 or 120-volt power strip may ruin the unit or the connected electrical wiring. It might also lead to a fire if you’re not careful. 

Frequently Asked Questions


What’s The Difference Between A Humidifier And Dehumidifier?

A humidifier increases the moisture in the air. On the other hand, a dehumidifier removes water vapor. Also, a humidifier can be a good companion in winter to combat dryness, while a dehumidifier is great for spring and summer.

How Many Amps Does A Dehumidifier Use?

A dehumidifier typically draws about 7.8 amps. But some low-power models may only need 2.2 amps to run. On the other hand, a heavy duty dehumidifier may need 10 amps to operate properly.

Can You Plug A Dehumidifier Into Extension Cord?

Like plugging a humidifier into a power strip, avoid using a dehumidifier extension cord.

Generally, this appliance needs a direct connection with wall outlets. Plugging a dehumidifier into an extension cord may cause the unit to overload the circuit.

Plug a dehumidifier into a power strip while leaving the setup as it is may put the strip at risk of catching water if the appliance leaks. Also, extending the cord may cause a voltage drop, reducing the dehumidifier’s performance.


By now, you should now know the answer to your initial inquiry, “Can you plug a humidifier into a power strip?” Remember, avoid using this setup despite its possibility.

Plugging a humidifier or dehumidifier into an extension cord may pose numerous risks. For instance, the power strip may catch fire from gathering water vapor or leakage from the unit.

Instead, make sure to plug the device into a wall outlet directly. Also, don’t forget to read your product’s owner’s manual to ensure you’re using it correctly and safely.
