7 Hazardous Devices You Should Never Plug Into Extension Cords: An Electrician’s Critical Warning

No matter the size of your home, it often feels like there aren’t enough outlets. While extension cords and power strips seem like quick fixes, they can be unsafe for certain appliances.

High-powered devices like air conditioners and space heaters should always be plugged directly into a wall outlet. Using extension cords for these appliances can lead to overheating and even fires. Paul Martinez, an expert from Electrified NYC, emphasizes, “No extension cords whatsoever” for devices that need continuous power or generate heat.

If you’re unsure which appliances require a direct connection, here are seven that you should keep in mind:

1. Air Fryers
   These popular gadgets can draw up to 2,000 watts. It’s best to use them in a wall outlet to avoid hazards.

2. Microwaves
   Similar to air fryers, microwaves require a dedicated circuit due to their high wattage.

3. Extension Cords
   Never plug one extension cord into another. This practice, known as “daisy chaining,” can cause overheating and create a fire risk.

4. Space Heaters
   Electrical space heaters are a significant fire hazard. Between 2017 and 2019, an estimated 1,700 fires were caused by portable space heaters each year, according to the Consumer Product Safety Commission. Connecting them to a power strip is especially dangerous.

5. Toasters and Toaster Ovens
   These appliances use a lot of energy. Toaster ovens, in particular, need between 1,200 and 1,400 watts. Using extension cords can lead to overheating and fires.

6. Refrigerators
   While they consume less power than some kitchen devices, refrigerators should not be plugged into extension cords since they run continuously. Doing so can cause malfunctions.

7. Air Conditioning Units
   AC units consume a lot of energy. Experts suggest using a proper size unit for your space, as undersized units can overwork and create risks.

Martinez also stresses that extension cords should not be used with any appliance that draws more than 15 amps (1,800 watts). Power strips are better suited for electronics.

Safety should always come first when it comes to electricity. By ensuring that high-powered appliances are plugged directly into wall outlets, you protect not just your home but also your peace of mind.
