Whether you’re planning to cook chicken wings or cheeseburgers in your air fryer, you’ll need to keep one very important thing in mind. Never, ever, plug your air fryer — or any other electrical devices that have a heating element, such as space heaters and microwaves — into extension cords or power strips.
Brooklyn electrician Paul Martinez, owner of Electrified NYC, explains that such appliances and ones that use 1,500 watts of power or more should always be plugged into a dedicated electrical wall outlet.
“No extension cords whatsoever,” he warns for such appliances.
When extension cords are paired with appliances that have a heating element, it can lead to overheating, burning and ultimately fires if not caught in time. If you’re not sure which devices and appliances shouldn’t be plugged into extension cords, here are seven important ones to remember.
1. Air fryers
Air fryers are great for quickly cooking and warming food, including full meals and side dishes, but it’s not a good idea to attach them to extension cords or power strips. Although they range in wattage based on size, large air fryers can draw up to 2,000 watts, making them a major fire hazard if they’re attached to an extension cord. If you don’t have counter space to keep your air fryer out full time, it’s best to only pull it out when needed and plug it into a dedicated wall outlet.
2. Microwaves
Many have homes with a built-in microwave, but not everyone has this feature. If you have to find a place to connect yours in your kitchen, this is another heavy-duty appliance that should live on its own dedicated circuit due to high wattage.
3. Extension cords
Plugging extension cords into other extension cords is another huge “no” in the electrical world. This practice, known as “daisy chaining,” can lead to the circuit overheating, which would cause the cords to overheat and lead to a fire.
4. Space heaters
Electric space heaters have long been known to be a major cause of fires. The Consumer Product Safety Commission previously estimated that between 2017 and 2019, portable space heaters were involved in 1,700 fires per year, with some of those fires resulting in deaths.
“Let’s say you connect [an extension cord] to a floor heater,” Martinez says, “the plug melts and it starts a fire. That’s why you can’t use extension cords and/or power strips for any appliances, because they should be used for electronics only.”

5. Toasters and toaster ovens
Although toasters are on the smaller side when it comes to kitchen appliances, they use a lot of energy and pose a fire threat if connected to an extension cord. Toaster ovens need even more power to operate with wattage ranging from 1,200 to 1,400 watts.
6. Refrigerators
Although refrigerators use less power — about 300 to 800 watts — than some other kitchen appliances, they’re still not recommended for extension cord use since they are constantly running. Even if an extension cord doesn’t cause a fire when attached to a fridge, there’s a possibility it could cause the fridge to malfunction.
7. Air conditioning units
AC units use too much power for an extension cord or power strip, so they need to be plugged into a wall outlet as well. Martinez also stresses the importance of purchasing the correct AC unit for your space. You can use an online BTU calculator to calculate the type you will need to effectively cool your space.
“People just buy a 5,000 BTU air conditioner, because it’s $99 on sale, and they think it’s going to cool off [their home], and it does not, ” Martinez says. “[AC units] are supposed to cycle on and off, so they don’t pull that much energy. So if you undersize it, the compressor is going to work 10 times harder.”
This can result in your home never properly cooling off, a higher electricity bill and if the unit is connected to an extension cord, possibly a fire.
The bottom line when it comes to extension cords
“A lot of people don’t have knowledge of extension cords,” said Martinez. “If extension cords are 14-gauge, and you’re running an appliance with a heating element, [such as] a toaster oven, microwave or dishwasher, a 14-gauge will not hold the amperage and can burn up the extension cord. And that’s what causes fires in New York City.”
He says you should also remember to only pair power strips with electronics, and that your average home extension cords shouldn’t be used for anything above 15 amps (1,800 watts), regardless of where or how the device operates.
