9 Appliances You Should Never Plug Into a Power Strip
Power strips are incredibly useful for chargers, lamps, and small electronics. But they are not made for every device in your home. When a power strip is overloaded, it can overheat, short out, or even start an electrical fire.
To reduce the risk of damage to your appliances and improve home electrical safety, here are 9 devices you should never connect to a power strip.
1. Refrigerators and Freezers
Refrigerators and freezers need steady power and often draw a strong electrical load when the compressor starts. A standard power strip is usually not built to handle that demand safely.

Using one can lead to overheating, power interruptions, or appliance failure, which may also put your food at risk.
Best practice: Plug refrigerators and freezers directly into a wall outlet.
2. Microwaves and Toaster Ovens
Microwaves and toaster ovens are high-wattage kitchen appliances. They consume a large amount of electricity in a short period, which can quickly overload a power strip.
That extra strain may cause the strip to overheat, melt, or become a fire hazard.
Best practice: Always use a dedicated wall outlet.
3. Coffee Makers and Slow Cookers
Coffee makers, slow cookers, and electric kettles all generate heat, and heating appliances typically require significant wattage. Most power strips are not designed to support that kind of sustained electrical demand.
Over time, this can create dangerous heat buildup.
Best practice: Connect these appliances straight to the wall outlet.
4. Space Heaters
Space heaters are one of the most dangerous devices to plug into a power strip. They use a very high amount of power and can easily push a strip beyond its safe limit.
Because they also produce heat, the fire risk increases even more, especially if nearby materials are flammable.
Best practice: Use only a dedicated wall outlet for a space heater.
5. Hair Dryers, Curling Irons, and Flat Irons
Hair tools often pull a lot of electricity very quickly. That sudden power demand can overload a power strip and may even trip your breaker.
These appliances are especially risky in bathrooms, where electrical safety matters even more.
Best practice: Plug them directly into a GFCI-protected bathroom outlet.
6. Air Conditioners and Portable Heaters
Air conditioners and portable heaters need continuous high power to run properly. Like space heaters, they can overwork a power strip and increase the chance of overheating or fire.
They should always be used on the correct circuit for their electrical load.
Best practice: Plug them into a dedicated wall outlet with the proper circuit support.
7. Washing Machines and Dryers
Laundry appliances use heavy-duty electrical power and are meant to operate on properly rated circuits. A power strip cannot safely manage that kind of load.
Improper use can lead to electrical damage, overheating, or a serious fire hazard.
Best practice: Use a properly grounded wall outlet designed for the appliance.
8. Power Tools
Drills, saws, air compressors, and similar tools often require sudden bursts of high energy. Standard power strips are not intended for these intense power spikes.
As a result, the strip may overheat or fail unexpectedly.
Best practice: Use an industrial-grade extension cord if appropriate, or plug the tool directly into a wall outlet.
9. Another Power Strip
Plugging one power strip into another, often called daisy chaining, is a major electrical safety risk. This setup can overload the circuit and significantly raise the chance of overheating and fire.
It may seem like an easy way to add more outlets, but it is unsafe.
Best practice: If you need extra capacity, choose a heavy-duty surge protector with built-in circuit protection.
Electrical Safety Tips to Help Prevent Fires
Follow these simple tips to use power strips more safely:
- Choose power strips with surge protection for added protection of electronics.
- Unplug devices when they are not in use to reduce heat buildup.
- Never cover a power strip with rugs, curtains, or furniture.
- Inspect cords regularly and replace any that are damaged or worn.
Final Thoughts
Power strips are perfect for low-power electronics, but they should never be used for large appliances or high-wattage devices. Avoid plugging in these 9 items to lower the risk of overheating, circuit overload, and electrical fires in your home.
Keeping these power strip safety rules in mind can help protect both your home and your appliances.
