9 Things You Should Never Plug Into a Power Strip: Avoid These Common Electrical Mistakes
Electricity powers nearly every aspect of modern life. From refrigerators and microwaves to televisions and smartphones, our homes depend on a steady supply of electricity to keep everything running smoothly. However, most homes don't have enough wall outlets to accommodate all the devices and appliances we use daily. That's why power strips have become a household essential.
Power strips offer a convenient way to expand the number of available outlets, allowing multiple devices to operate from a single wall receptacle. While they are incredibly useful for low-power electronics and charging devices, many people unknowingly misuse them by plugging in appliances that draw more electricity than a power strip is designed to handle.
This mistake can have serious consequences. Overloaded power strips can overheat, damage expensive equipment, trip circuit breakers, and in some cases, even start electrical fires.
Understanding which devices should never be connected to a power strip is an important step toward maintaining a safer home. In this article, we'll explain why certain appliances require dedicated outlets and reveal the nine items you should never plug into a power strip.
Why Power Strip Safety Matters
Before diving into the list, it's important to understand how power strips work.
Most standard power strips are designed to handle a maximum load of approximately 1,500 to 1,800 watts. While this is sufficient for computers, lamps, phone chargers, and other small electronics, many household appliances consume far more power.
When a high-wattage appliance exceeds the strip's capacity, excessive heat can build up inside the wiring. Over time, this can damage the strip, melt insulation, or create conditions that increase the risk of an electrical fire.
The National Fire Protection Association and electrical safety experts consistently recommend plugging high-power appliances directly into a properly installed wall outlet whenever possible.
1. Ovens and Countertop Ovens
Ovens are among the most energy-hungry appliances in any home.
Whether it's a full-sized electric oven or a powerful countertop convection oven, these appliances generate large amounts of heat and require significant electrical current to operate safely.
Why They Shouldn't Be Plugged Into a Power Strip
High wattage requirements
Extended periods of operation
Significant heat generation
Increased risk of overheating
Many ovens require their own dedicated circuit to prevent overloads.
Safer Alternative
Always plug ovens directly into a wall outlet specifically designed to handle their electrical load.
2. Refrigerators and Freezers
Refrigerators run continuously throughout the day and night. Although they don't consume maximum power constantly, they require large bursts of electricity whenever the compressor starts.
Potential Problems
Frequent power cycling
High startup current
Risk of voltage fluctuations
Potential food spoilage if power is interrupted
Using a power strip can interfere with proper operation and may damage both the appliance and the strip.
Best Practice
Plug refrigerators and freezers directly into a dedicated wall outlet.
3. Washing Machines
Modern washing machines contain motors, pumps, heating elements, and electronic controls that require substantial power during operation.
Risks of Using a Power Strip
Excessive electrical load
Long operating cycles
Increased heat buildup
Fire hazards if overloaded
Many washing machines draw between 500 and 1,500 watts depending on the cycle and model.
Safety Recommendation
Use a dedicated outlet designed specifically for laundry appliances.
4. Portable Space Heaters
Portable heaters are among the most common causes of household electrical overloads.
Most residential space heaters operate at approximately 1,500 watts on their highest setting, which often approaches the maximum safe capacity of many power strips.
Why Space Heaters Are Dangerous on Power Strips
Extremely high power consumption
Long periods of continuous operation
Significant heat production
Increased risk of electrical fires
Electrical safety organizations frequently warn homeowners never to connect space heaters to extension cords or power strips.
Safer Solution
Plug space heaters directly into a wall outlet and keep them away from flammable materials.
5. Microwaves
Microwave ovens may appear compact, but they require substantial power to generate heat quickly.
Depending on the model, microwaves can consume between 600 and 1,500 watts or more during operation.
Potential Dangers
Power surges during startup
Overloaded circuits
Damaged power strips
Reduced appliance lifespan
Many kitchens are designed with dedicated outlets specifically for microwave ovens.
Recommended Practice
Always plug microwaves directly into a properly grounded wall outlet.
6. Coffee Makers
For many people, the day doesn't begin until the coffee maker starts brewing. What many homeowners don't realize is that coffee makers use heating elements that draw considerable electrical current.
Why They Need Direct Power
Rapid heating requirements
High wattage consumption
Extended brewing cycles
Potential overheating of power strips
Single-serve coffee machines and traditional drip coffee makers alike should be treated as high-demand appliances.
Best Option
Use a dedicated wall outlet whenever possible.
7. Toasters and Toaster Ovens
Toasters create heat almost instantly by sending large amounts of electricity through internal heating elements.
Hidden Power Consumption
Many standard toasters consume:
800 watts
1,000 watts
1,200 watts
Or even more
While the appliance may only operate for a few minutes, the electrical demand during that time is substantial.
Safety Concerns
Sudden power spikes
Excessive heat generation
Risk of overloaded strips
Proper Use
Always connect toasters directly to a wall outlet.
8. Another Power Strip
This practice is commonly known as "daisy chaining."
Daisy chaining occurs when one power strip is plugged into another power strip to create additional outlets.
Why This Is Dangerous
Many people assume that connecting multiple strips increases capacity. In reality, it only increases the number of outlets—not the amount of electricity available.
Potential risks include:
Circuit overload
Excessive heat buildup
Increased fire hazards
Violation of electrical safety guidelines
Many workplace and commercial building safety codes specifically prohibit daisy chaining power strips.
Better Alternative
Install additional wall outlets or use a properly rated surge protector when appropriate.
9. High-Value Electronics Without Surge Protection
Computers, televisions, gaming consoles, routers, and home entertainment systems may not draw enormous amounts of power, but they are extremely sensitive to electrical fluctuations.
The Hidden Risk
Standard power strips provide extra outlets, but many do not offer meaningful surge protection.
Without protection, devices may be vulnerable to:
Power surges
Voltage spikes
Lightning-related electrical damage
Premature equipment failure
Better Choice
Use a certified surge protector designed specifically for sensitive electronics.
A quality surge protector can help safeguard expensive equipment from unexpected electrical events.
Other Appliances to Use With Caution
While the nine items above are among the most commonly cited examples, several other appliances may also require direct wall outlets.
Hair Dryers
Hair dryers often consume between 1,000 and 2,000 watts.

Many indoor grills use heating elements similar to toasters and coffee makers.
Dehumidifiers
Depending on size and operating conditions, these appliances can place heavy demands on electrical circuits.
When in doubt, consult the manufacturer's instructions.
Understanding Wattage and Electrical Load
One of the easiest ways to prevent overloads is to understand how much power your appliances use.
What Is Wattage?
Wattage measures the amount of electrical power an appliance consumes.
Examples include:
Phone charger: 5–20 watts
Laptop: 30–100 watts
Television: 50–400 watts
Space heater: 1,500 watts
Microwave: 1,000–1,500 watts
When multiple devices share a power strip, their wattage adds together.
If the combined total exceeds the strip's rating, overheating can occur.
Check the Label
Most appliances include a label showing:
Voltage
Amperage
Wattage
Reviewing these numbers can help you determine whether a power strip is appropriate.
Signs Your Power Strip Is Overloaded
Recognizing warning signs early can prevent dangerous situations.
Watch for:
Excessive Heat
A power strip should never feel hot to the touch.
