Can You Plug a Microwave Into a Power Strip – [In-Depth Answer]

Can you plug a microwave into a power strip? Can you plug a toaster oven in the same socket with an extension cord going to the fridge? Would it be possible to turn on both at once without blowing the house out?

People have asked themselves these questions when using their microwaves and appliances at the same time. This blog post explores whether it is safe for your devices and what can happen if they don’t work together.

Why can you plug a microwave into a power strip?

Let’s start with the basics. The purpose of a power strip is to allow multiple devices to run from one outlet. Meaning you can use several electric appliances with a single power strip without having any issues. But the question is why you should not use Microwave into a power strip with multiple devices?

A microwave oven cannot be used in this setup, especially with an extension cord, because microwave ovens have their fuse, not designed to handle the high power needed when plugged into an extension cord.

Also, a microvan may cause the power strip wires to overheat, leading to a fire. Furthermore, the outlet must be updated with a special RCCB (Residual Current Circuit Breaker) to prevent any potential damage resulting from overheating the power strip wire.

Are power strips safe?

It is safe to assume that a power strip with a built-in fuse or circuit breaker is electrically safe. Although I will not recommend leaving it plugged in a while, not in use.

A power strip protects against electrical overload, but it is not a permanent replacement for a circuit breaker. In addition, an overload condition can pose a fire risk.

It is better to use an overcurrent protection device designed for the application or a circuit breaker. So a power strip is safe when you plug in your TV but wouldn’t be safe if you plugged in your air conditioner.

Can you plug a microwave into an extension cord?

In a word. No. Microwave ovens draw much power and damage an extension cord if they short circuit or pull too many amps.

Extension cord for microwave & High Power Devices

A typical household extension cord can be used to power a microwave. As microwaves use so much power, it is important to use an extension cord with the correct amperage. Many microwaves come with a power rating of 800 watts or more, so make sure to buy an extension cord that can handle the power requirements of your microwave.

Note- It is better to use always wall outlet instead of using extension cord for heavy duty electronic devices like like space heaters, refrigerators, or microwave and toaster ovens.

How much does a microwave surge protector cost?

An average surge protector/power strip for a microwave costs around 50 dollars. 

The average price for a good product is around 100 dollars, but keep in mind that some models are very cheap, but they might damage your appliance over time.

Never plug these items into a power strip

  • Hairdressing appliances: Some hair styling appliances, such as hairdryers, curling irons, and straighteners can operate at 1,500 volts. So when plugged one of them into a power strip, the voltage is reduced due to impedance, and the appliance will not work. You can read Why your power strip keeps turning off?
  • Refrigerator and freezer: A refrigerator’s compressor uses a lot of energy and is connected to a dedicated outlet. When plugged into a power strip, it will energize all the components attached to the strip and cause an electrical fire.
  • Coffee maker: Is it safe to only use a power strip to charge your cell phone? A coffee maker’s charging unit contains 240 volts, which are used to power all the components. So it would be best if you did not use a high-power coffee maker in a power strip.
  • Toaster: Toasters generally contain 240 volts of electricity, so they should not be plugged into a power strip. So if you plug in, it will create 240 volts of power, carrying a current that was not designed for it.
  • Slow cooker: Slow cookers should be plugged into a dedicated outlet. They usually contain 240 volts of electricity, so they cannot be plugged into a power strip. Instead, slow cookers should be connected to a power strip with a circuit breaker.

Overall, using power strips with high-voltage appliances can lead to fires or electric shocks. So always try to avoid high power devices to plug in a regular power strip even with multiple devices.

wall outlets

What if I don’t have enough outlets?

If you have a lot of components that need to be plugged into the wall, it is best to install additional outlets. Installing extra outlets is easy to do and can save you a lot of money.

If there are no available electrical outlets, you should try to choose a high-quality power strip with surge protection and circuit breakers. It would be best never to plug power strips into other power strips, as there is always a risk of overloading the circuit.

Also, you can use an extension cord. There are many extension cords or outlets available on the market, depending on your needs. 

  • Only use extension cords that are rated for the expected workload.
  • Inspect each cable before every use. If the line is frayed or cracked, do not use it.
  • Never overload a power strip.
  • Use electrical tape to cover any exposed wire.
  • Use extension cords that are rated for outdoor use when necessary.
  • Do not run an electrical line under a rug if possible.
  • If you must use an electrical cord under a carpet, make sure to lay it flat and fasten it to the floor with tape.
  • Avoid running electrical cords through doorways or windows.

Can you plug a humidifier into a power strip?

Generally, it would be best not to use a power strip for your humidifier because it can cause a fire hazard. If you intend to plug a humidifier into a power strip, make sure the strip has a circuit breaker and a fuse. Furthermore, it would be helpful to use only power strips that an independent testing laboratory has approved.

What should you do instead of using a power strip?


  • Plug your power strip into a grounded outlet.
  • Use the manufacturer’s recommended number of outlets on the power strip.
  • Choose a strip that can accommodate the number of items you need to plug in.
  • Unplug the power strip when not using it.
  • Purchase a power strip that features a built-in circuit breaker that trips if the strip becomes overloaded.


  • Do not plug too many items into one power strip.
  • Likewise, don’t use multiple power strips to make up the total amperage you need.
  • Avoid plugging in devices that create strong magnetic or electric fields, such as televisions, microwaves, and refrigerators.
  • Do not allow cords to lie across an outlet or along the floor where someone could trip on them.


Power strips are helpful, but you should avoid using them with high-voltage devices since they can cause fires. To prevent electrical fires, it is best to use dedicated electrical circuits for high-energy appliances. Furthermore, you can connect devices directly to the wall and eliminate the need for power strips.

It would help if you used a power strip with good UL ratings (700+ Joules) and the highest amperage possible with the wattage of your appliances. The higher the amperage, the better. Also, be sure to unplug devices when they are not in use.

So I hope you got the correct answer to the question: can you plug a microwave into a power strip?
