Please be careful: 7 Things You Should Never Plug Into A Power Strip

Power Strip Safety: What You Should—and Shouldn’t—Do

Power strips are convenient household tools, allowing multiple devices to run from a single outlet. They’re found in nearly every home, office, and classroom. However, many people don’t realize that improper use can turn these everyday tools into serious fire hazards. Understanding how to use power strips safely—and knowing what not to plug into them—can protect both your home and your loved ones.

Know the Limits

Every power strip has a maximum capacity, usually listed on its label or cable in terms of amps or watts. Exceeding that limit by plugging in too many high-energy devices can cause overheating, which may lead to melted insulation, sparks, or even electrical fires. Before using a strip, always take a moment to check its capacity and compare it with the wattage of the devices you plan to plug in.

Appliances That Should Never Be Plugged into Power Strips

Some appliances are simply too powerful for power strips. These should always be connected directly into wall outlets on separate circuits:

Ovens and microwaves: Both draw large bursts of energy during operation.
Refrigerators and freezers: Their compressors cycle on and off, creating sudden spikes in energy demand.
Washing machines and dryers: These heavy-duty appliances require dedicated outlets due to their motor power.
Coffee makers and toasters: While smaller, they generate intense heat and demand significant energy when active.

Plugging these into a strip risks tripping the breaker at best—or causing dangerous overheating at worst.

The Danger of Heating Devices

One of the most dangerous mistakes is plugging space heaters or other heating devices into power strips. These appliances draw large amounts of current continuously, which quickly overwhelms most strips. Fire departments frequently warn that auxiliary heaters connected to power strips are a leading cause of home electrical fires. To stay safe, plug heaters directly into a wall outlet, and never leave them running unattended.

Never “Daisy-Chain” Power Strips

It may be tempting to plug one power strip into another to extend reach or add more outlets, but this practice, known as daisy-chaining, is extremely unsafe. Each strip has its own capacity limit; when stacked together, the load can multiply far beyond what the first strip or the circuit itself can handle. This greatly increases the risk of overloading and fire. Instead, use an appropriate extension cord rated for the job or, better yet, install additional wall outlets if you consistently run out of space.

Protecting Sensitive Electronics

Devices like computers, televisions, routers, and gaming consoles may not consume as much power as large appliances, but they are highly sensitive to surges. Plugging them directly into wall outlets—or better, into a surge protector designed to absorb voltage spikes—offers better protection than a standard strip. This is especially important in areas prone to power fluctuations or storms.

Practical Safety Tips

Regularly inspect your power strips for frayed cords, scorch marks, or loose sockets.
Avoid placing strips under rugs or in tight spaces where heat cannot dissipate.
Unplug strips when not in use to reduce risk.
If you need more outlets permanently, consult an electrician rather than over-relying on strips.

Conclusion

Power strips are useful tools, but they are not meant to handle heavy-duty appliances or serve as permanent wiring solutions. By avoiding high-power devices, steering clear of daisy-chaining, and checking each strip’s capacity, you can reduce fire risks and keep your home safe. Electrical safety begins with awareness—and a little caution goes a long way.
