The Electrical Devices You Should Never use with power strips.
In today’s technology-filled households, power strips have become almost as common as light switches. From home offices and entertainment centers to bedrooms and kitchens, it’s rare to find a space that doesn’t rely on at least one power strip to handle the growing number of electronic devices we use every day.

They’re convenient. They’re affordable. They help expand limited wall outlets into multiple connection points. But while power strips are incredibly useful, they are not designed to handle every type of device.

Misusing a power strip can create serious electrical hazards, including overheating, equipment damage, and in some cases, fire risks. Many people assume that if a plug fits, it’s safe to use. Unfortunately, that’s not always true.

Understanding what should — and should not — be plugged into a power strip is one of the simplest ways to protect your home, your appliances, and your family.

In this comprehensive guide, we’ll break down:

How power strips actually work

Why overloading them is dangerous

The types of devices that should never be connected to one

Safe alternatives and best practices

How to choose the right power strip

Warning signs of electrical overload

Smart home electrical safety habits

Let’s start with the basics.

How Power Strips Work (And Their Limits)

A power strip is essentially an extension of a single wall outlet. It does not increase the total amount of electricity available — it simply distributes the same electrical capacity across multiple sockets.

Most residential wall outlets in the United States operate on a 15-amp or 20-amp circuit. That means there’s a limit to how much electrical load that circuit can safely handle at one time.

Power strips are typically designed for:

Chargers (phones, tablets, laptops)

Lamps

Televisions

Modems and routers

Desktop computers

Small office electronics

They are not designed for heavy-duty appliances or high-wattage equipment.

When too much power is drawn through a single strip, it can:

Overheat internally

Melt insulation

Trip breakers

Damage connected devices

Increase fire risk

The key issue is load capacity.

Let’s explore the types of devices that exceed safe limits.

1. Major Household Appliances

Large appliances require a significant and consistent flow of electricity. These include:

Refrigerators

Freezers

Washing machines

Dryers

Dishwashers

These devices are engineered to operate on dedicated circuits. That means they are intended to be plugged directly into a wall outlet — often one that is specifically wired for that appliance alone.

Why?

Because major appliances:

Draw high amperage

Cycle on and off frequently

Require stable voltage

Can cause sudden electrical spikes

Plugging them into a power strip can overload the strip and the circuit. Even if it seems to “work” at first, the internal wiring of the strip is not designed to handle that continuous heavy load.

Over time, this can lead to overheating or electrical failure.

Safe Practice: Always plug large appliances directly into a properly rated wall outlet.

2. Space Heaters

Space heaters are one of the most common causes of electrical fires during colder months — especially when misused.

They generate heat by drawing a large amount of power, often 1,200 to 1,500 watts or more.

Power strips are rarely rated to handle that sustained load.

When a space heater is plugged into a strip:

The strip may overheat

Internal components can melt

The risk of fire increases

Circuit breakers may trip

Even heavy-duty surge protectors are not designed for space heaters.

Safe Practice: Plug space heaters directly into a wall outlet — never into an extension cord or power strip.

3. High-Wattage Kitchen Appliances

Kitchen appliances often consume more electricity than people realize.

Examples include:

Microwaves

Toaster ovens

Air fryers

Coffee makers

Electric kettles

Blenders

These devices use heating elements or powerful motors. That means high wattage and short bursts of heavy electrical demand.

Plugging them into a power strip can result in:

Voltage drops

Overloaded circuits

Reduced appliance lifespan

Electrical hazards

Kitchen circuits are often specially rated to handle higher loads — but only when appliances are plugged directly into the outlet.

Safe Practice: Use wall outlets for cooking appliances.

4. Daisy-Chaining Power Strips

Daisy-chaining occurs when one power strip is plugged into another to increase the number of outlets.

This is extremely unsafe.

Each additional strip adds:

Electrical resistance

Heat buildup

Potential failure points

The more devices you add, the greater the load on a single wall outlet.

This practice significantly increases fire risk and is prohibited in many commercial and workplace safety regulations.

Safe Practice: Use a single high-quality power strip with sufficient outlets. If more outlets are needed, consult an electrician.

5. Air Conditioners

Air conditioners are among the highest power-drawing appliances in a home.

They:

Require high startup current

Run for extended periods

Produce electrical surges when cycling

Using a power strip for an air conditioner can:

Cause overheating

Trip breakers

Damage the AC unit

Increase fire risk

These units should always be connected directly to a properly rated wall outlet.

6. Laser Printers and Photocopiers

Unlike inkjet printers, laser printers use heating elements to fuse toner to paper. This process requires a large surge of power during operation.

Plugging a laser printer into a standard power strip can:

Cause voltage fluctuations

Trip circuit breakers

Damage the printer

Shorten device lifespan

Safe Practice: Connect laser printers and large office machines directly to a wall outlet.

7. Aquariums with Heating Systems

Aquariums often include:

Water heaters

Filtration systems

Lighting

Pumps

Combined, these components can draw more power than expected.

Water and electricity together demand extra caution. Overloaded strips increase the risk of malfunction or electrical hazards.

Safe Practice: Use a dedicated outlet with proper safety precautions for aquarium setups.

8. Electric Grills and Indoor Cookers

Appliances that generate heat — such as electric grills and cooktops — draw high wattage similar to space heaters.

Using a power strip for these devices can lead to overheating and potential fire hazards.

Always plug heating appliances directly into a wall outlet.

9. Medical Equipment

Medical devices such as:

CPAP machines

Oxygen concentrators

Nebulizers

Require a stable, uninterrupted power source.

Power strips can introduce risk of:

Accidental shutoff

Loose connections

Electrical instability

For devices critical to health, always use a wall outlet and follow manufacturer instructions carefully.

Warning Signs Your Power Strip Is Overloaded

Watch for:

Warm or hot plastic casing

Burning smell

Flickering devices

Frequent breaker trips

Melted insulation

If any of these occur, unplug devices immediately and reassess your setup.

How to Choose a Safer Power Strip

If you use power strips for appropriate devices:

Choose UL-listed products

Look for surge protection

Check amp rating

Avoid thin or damaged cords

Replace old strips

Never place power strips under rugs or furniture where heat can build up.

Smart Electrical Safety Habits for Every Home

Spread high-wattage devices across different circuits

Avoid overloading single outlets

Schedule regular electrical inspections

Upgrade old wiring when necessary

Teach children outlet safety

Creating a Safer Electrical Setup for the Long Term

Beyond knowing what not to plug into a power strip, it’s helpful to take a broader look at how electricity flows through your home. Many houses—especially older ones—were not originally designed to handle the number of devices we rely on today. Between smart TVs, gaming consoles, home office equipment, kitchen gadgets, and climate-control devices, the electrical demand in a modern household can be significantly higher than it was decades ago.

If you find yourself constantly reaching for extra power strips, that may be a sign your home needs additional outlets or even an electrical upgrade. A licensed electrician can assess whether your circuits are properly balanced and determine if new dedicated outlets should be installed for heavy-duty appliances. While this may seem like an added expense, it’s a worthwhile investment in safety and long-term reliability.

It’s also wise to periodically inspect your cords and plugs. Frayed wires, loose prongs, cracked insulation, or discoloration around outlets can all signal potential electrical issues. Replace damaged strips immediately rather than continuing to use them. Even small defects can increase resistance and heat buildup over time.

Another good habit is unplugging devices when they’re not in use—particularly higher-wattage electronics. This not only reduces electrical strain but can also lower energy consumption. Smart power strips, which automatically cut power to idle devices, are a safer alternative for managing multiple low-power electronics like chargers and entertainment systems.

Ultimately, power strips are tools meant to simplify your life—not create hidden risks. By understanding their limitations, avoiding high-demand appliances, and maintaining your home’s electrical system, you create a safer environment for everyone under your roof. Electrical safety isn’t complicated, but it does require attention. A few mindful adjustments today can prevent serious problems tomorrow.

Final Thoughts: Convenience Should Never Compromise Safety

Power strips are helpful tools — but only when used properly.

They are designed for low-power electronics, not heavy appliances. Understanding their limitations protects your home from unnecessary risk.

A good rule of thumb:

If it heats, cools, or contains a motor — plug it into the wall.

Electrical safety doesn’t require complex knowledge — just awareness and responsible habits.

Taking a few minutes to evaluate what’s plugged into your power strips today could prevent costly damage — or something far worse — tomorrow.

Stay safe, stay informed, and always prioritize proper electrical practices in your home.

In January, the parking lot lighting system in front of Goddard School ceased functioning. Upon diagnosis, a short circuit and severe burns to the wiring were identified.

Utilizing Level 3 Circuit tracer, the suspected location of the conduits in the ground was determined.
Our extensive experience of over 37 years in diagnosing and resolving complex underground wiring failures is unparalleled. I was able to pinpoint the location of the failure to within 12 inches, at a depth of 36 inches.

Excavation of blacktop and soil exposed the issue, in front of the pole to find the damaged conduit. It was discovered that the conduit had been damaged by a contractor who previously installed bollards, resulting in nicks to the wiring.

The damaged conduit was cut back, and a Quazite direct burial junction box was installed. The wiring was extended back into the pole and energized the circuit.

This project was a collaborative effort between our team and Hage Landscaping, who provided excavation and backfilling services.
The Goddard School and UFC Gym are now able to resume their operations with fully functional parking Lot lighting. Shine On💎

One of my favorite quotes and one I live by every day:
“Integrity is doing the right thing, even when no one is watching” - C.S Lewis
Consumers should exercise caution when dealing with unethical contractors. Any service provider that aggressively states that your electrical service or panel is a fire hazard without providing a comprehensive on-site assessment is unethical.
They employ fear-based tactics to sell unnecessary products. These companies, often acquired by private equity firms, prioritize sales growth and exploit your apprehension regarding fire hazards.
I recommend reviewing their written quote and contacting me for an inspection. I will thoroughly evaluate the quote and provide you with an accurate assessment.

Today, a client in East Brunswick engaged Danley911 for annual generator maintenance, a service they have consistently provided since 2018.

During the generator service, the technician raised concerns with Mrs. Jones about the potential fire hazard posed by her electric panel and recommended its replacement.
Mrs. Jones expressed surprise and skepticism, questioning why Danley911 had not previously raised these concerns despite their extensive experience in the area.
She also noted that two other electricians had installed new circuits without mentioning the panel’s issues.

Mrs. Jones decided to address the matter promptly and scheduled an appointment with the company’s estimator to obtain a quote. The estimator provided a quote of $7,000 for the replacement of the 100-amp panel, plus an additional $975 for surge protection, which he highly recommended. The total cost amounted to approximately $8,000.

It is important to note that all services and panel replacements are now required to include surge protection, making it a mandatory requirement.

Mr. Jones sent the estimator on his way and said would review his quote and get back to them. Over the past week, he has received numerous emails and calls from Danley911, urging him to sign the quote and join their schedule.

Mr. Jones called me to obtain a second opinion, I conducted a thorough inspection of the panel and utilized a thermal heat gun to identify if any hot spots are present. The results were satisfactory, indicating that no immediate danger was present. Therefore, no panel replacement was necessary.

Even if the panel had been deemed faulty and required replacement, the cost would have been approximately $4,000, including surge protection.

After my inspection, I informed Mr. Jones that there was no imminent danger and that Danley911 had attempted to take advantage of him and his wife.

He will be calling Danley911 today, as well as a call to the Department of Consumer Affairs (DCA) on Monday.
