15 Appliances You Should Never Plug Into a Power Strip
Think your power strip is a safe catch-all for all your devices? Think again. While these handy gadgets are great for charging phones, powering lamps, or connecting low-wattage electronics, they’re not built to handle high-powered appliances.
Plug the wrong device into a strip, and you could be looking at overloaded circuits, fried gadgets, or even a house fire. Many homeowners make this mistake daily without realizing the risk. Here’s what you need to know—and what never to plug into a power strip.
Power strips are rated for a specific amount of electricity, usually around 15 amps (1,800 watts) for standard models, and up to 20 amps (2,400 watts) for heavy-duty versions. Exceeding these limits can quickly become dangerous. Keep these 15 high-draw items away from strips:
Refrigerators
These appliances cycle constantly, pulling large bursts of electricity. Always plug refrigerators directly into a wall outlet.
Microwaves
Cooking, defrosting, and reheating demand more power than a strip can supply—stick to a dedicated outlet.
Coffee Makers
Even a standard coffee brewer requires significant electricity. Using a strip could cause incomplete brewing or overheating.
Toasters, Waffle Makers, and Similar Appliances
These heat elements draw heavy currents, which can overheat a strip almost instantly.
Slow Cookers
Continuous power draw over hours is too much for a strip; wall outlets are safer.
Hair Dryers, Curling Irons, and Straighteners
High wattage plus the risk of water in bathrooms makes strips a hazard. Use GFCI outlets.
Portable Air Conditioners
Air conditioners pull large currents and can easily trip or melt a strip; always use a dedicated outlet.
Sump Pumps
These protect basements from flooding, but moisture plus high wattage makes a strip unsafe. GFCI outlets are recommended.
Air Compressors
DIY tools often need heavy current to start. A power strip just isn’t up to the task.
Other Power Strips
Never daisy-chain strips—plugging one into another is a major fire hazard and violates most fire codes.
Blenders and Juicers
High-powered blenders draw as much electricity as small heaters. Liquids plus strips equal double danger.
Washing Machines
Long cycles with high wattage can overload a strip. Use a wall socket exclusively.
Space Heaters
Even with built-in safety features, extended use can cause strips to overheat.
Power Tools
Saws, drills, and other workshop equipment need thick wiring or specialized outlets—not a standard strip.
Gaming Rigs and Multiple Electronics
A console alone may be fine, but combining it with a PC, monitor, speakers, and lights can exceed a strip’s capacity. Check wattage first.
Bottom Line
Power strips are for convenience, not for heavy-duty electricity. Overloading them can lead to tripped breakers, overheating, or serious fires. To stay safe, always plug high-wattage appliances directly into wall outlets and reserve strips for small electronics. Checking wattage and being mindful of your load isn’t just smart—it’s essential for protecting your home and family.
