Extension cords and power strips are handy tools for extending power to electronics, but they aren’t suitable for every device. Using them incorrectly can lead to overheating, electrical failures, or even fires. Here’s why you should avoid plugging these seven devices into extension cords and always opt for a dedicated wall outlet instead.
Why Extension Cords Aren’t for Every Device
Extension cords are designed with specific power limits, determined by the cord’s wire gauge. For instance, a 16-gauge cord handles up to 13 amps, while a 14-gauge cord supports 15 amps (or 1,800 watts), similar to a standard wall outlet in the U.S. Overloading these limits can cause the cord to overheat, melting insulation, and exposing wires, which poses a fire hazard.
Appliances That Should Be Plugged Directly Into Wall Outlets
- Refrigerators
Refrigerators run continuously, drawing substantial power despite not having heating elements. Using an extension cord can lead to power fluctuations, potentially damaging the appliance and increasing fire risks. - Toasters and Toaster Ovens
These small kitchen appliances require significant energy, ranging from 1,200 to 1,400 watts. Plugging them into an extension cord increases the chance of overheating and fire hazards. - Air Fryers
Air fryers, especially larger models, consume up to 2,000 watts of power. Their high heat output makes them unsuitable for extension cords, which can overheat under the load. - Microwaves
Microwaves vary in wattage from 600 to 1,000 watts, depending on their size. Larger models require a dedicated circuit to operate safely, as extension cords can’t handle their power demand reliably. - Air Conditioning Units
Portable and window AC units demand substantial power, often exceeding 1,900 watts. Using an extension cord for these high-wattage appliances risks overheating and potential fires. - Space Heaters
Space heaters are among the most common causes of household fires due to their high energy consumption. They typically generate over 5,120 BTUs per hour, far exceeding the capacity of extension cords. - Other Extension Cords
Daisy-chaining extension cords—connecting one cord to another—is a major safety hazard. This practice can lead to overloaded circuits, overheating, and increased fire risks.
Safety Tips for Using Extension Cords
- Never plug devices that draw over 1,800 watts into an extension cord.
- Use appliances like microwaves, refrigerators, and space heaters with dedicated circuits.
- Ensure cords are undamaged and rated for the devices they power.
- Avoid daisy-chaining extension cords under any circumstances.
The Bottom Line
Extension cords are convenient for low-wattage electronics but aren’t designed for high-power appliances. Plugging these seven devices directly into a wall outlet ensures safety, protects your appliances, and minimizes fire hazards. Always prioritize proper electrical practices to keep your home and loved ones safe.
