In today’s world, our homes are filled with gadgets — laptops, phone chargers, TVs, gaming consoles, coffee makers, and more. With so many devices competing for limited wall outlets, the humble power strip (also known as a surge protector or “alargue” in Argentina) has become a household essential.
It’s convenient. It’s affordable.
But here’s the truth:
Using a power strip incorrectly can be dangerous — even deadly.
While power strips are incredibly useful, they are not designed to handle the power demands of every appliance. Misuse can lead to overheating, electrical fires, and costly damage to your devices — or worse, your home.
In fact, electrical issues cause nearly 30% of home fires, and overloaded power strips are a leading culprit.
Let’s break down the risks — and which appliances should never be plugged into a power strip.
How Power Strips Work — And Where They Fall Short
A power strip is essentially an extension of your wall outlet, allowing you to plug in multiple devices at once. Many come with:
- Circuit breakers
- Surge protection
- On/off switches
But here’s the catch:
Every power strip has a maximum power capacity, usually listed in watts (W) or amperes (A).
Most standard strips handle up to 1,800–2,000 watts — but many appliances exceed this limit, especially when used together.
When you plug in too many high-wattage devices, the strip can:
- Overheat
- Melt
- Spark
- Catch fire
And because power strips are often tucked behind furniture, under rugs, or near curtains, a fire can start unnoticed.
Appliances That Should NEVER Be Plugged Into a Power Strip
These devices draw too much power and should always be plugged directly into a wall outlet:
1. Space Heaters
2. Air Conditioners (Portable or Window Units)
3. Microwaves
- Power draw: 600–1,500 watts
- Risk: High energy use during operation, especially when combined with other devices.Avoid sharing a strip with other kitchen appliances.
4. Refrigerators & Freezers
- Power draw: 150–800 watts (but spikes when compressor kicks in)
- Risk: Power strips can fail during startup surges, causing food spoilage or fire.
- Plug into a dedicated outlet.
5. Hair Dryers, Curling Irons, and Flat Irons
Signs Your Power Strip Is Overloaded or Unsafe
Watch for these red flags:
- The strip feels hot to the touch
- The plastic is discolored or warped
- The circuit breaker keeps tripping
- Devices flicker or shut off
- A burning smell near the strip
If you notice any of these, unplug it immediately.

Final Thoughts: Convenience Should Never Cost Your Safety
Power strips are a modern necessity — but they’re not magic.
They’re electrical tools with limits.
By understanding those limits and respecting them, you can protect your home, your family, and your devices.
So next time you reach for that power strip, ask yourself:
“Am I making life easier — or risking a fire?”
Because the few seconds it takes to plug an appliance directly into the wall could save your home.
Stay safe. Stay aware. And never overload your outlets.
