7 Things Never To Plug In A Power Strip


It doesn’t matter in what corner of the world does one reside; there never seems to be enough power outlets in the households. This quarantine has got us using our gadgets more than usual. As a result, every socket gets occupied by a charging device, and sometimes, you can’t find an empty socket to charge your laptop. 

Thankfully, we don’t have to go through that inconvenience anymore because of the invention of power strips. It is an extension cord that has multiple power outlets. This means that you can simultaneously use or charge various gadgets. 

Like any other electrical appliances, power cords have their own sets of dos and don’ts. They are meant to carry small loads, as they divide the power received directly from the outlet. This is why you should never use certain appliances with power cords. Read ahead to know more.

Another Power Strip

Power strips are made to divide the electricity from outlets equally. While it may sound like an efficient idea to multiply outlets, this idea will do more harm than good. If you chain a power strip to another, it could result in short circuits. Also known as daisy-chaining, this is one of the most common newbie mistakes made by people, and many of them don’t realise the harm chaining power strips can do due to the risk of short circuits. 


Refrigerators are a necessity, and almost every household owns one. Since they are frequently used, they need more electricity to operate. A power strip cannot fulfill this requirement and can easily overload as a result. Large and needy appliances like refrigerators should only be plugged into wall sockets. If you’re confused, consider investing your money in a surge protector or a power strip. Remember always to check the voltage ratings of the flat cord power strip. That way, you can know precisely the amount of power your strip can handle. 

Space Heaters

Like a refrigerator, space heaters also continuously keep cycling on and off. That results in a flow of current that is too drastic for a little power strip to handle. They’re just not made for it. It drains too much electricity out of a strip that was only made for charging phones, laptops, or alarm clocks. If you’re still persistent enough to try, remember that the tremendous amount of current will cause overheating and then lead to a fire. 

Hair Appliances


You could be running late for office and want to straighten your hair for a touch-up quickly. If you plug your hair straightener directly into a wall socket, you’re good to go. But in a hurry, do not try plugging in your hair straightener into a power strip. Hairdryers, straighteners, curling wands and LED lights require a lot of heat to work properly. This means that they need the right amount of electricity to get them heated quickly.


Power strips cannot offer the power for these appliances to work safely and efficiently. Therefore, it’s best to find a wall socket to plug it in. 


Slow Cooker

The power strip could handle the microscopic units required for a slow cooker. The problem here is not the quantity, but the amount of time needed. 

Power strips are there to work for long intervals of time. A slow cooker needs continuous power for extended intervals. The strips cannot efficiently deliver the electricity that a slow cooker needs for proper functioning. So, just set a timer, plug the cooker into a wall socket and forget about it till your meal is made.

Microwaves and Ovens 

They may seem like small appliances, but they are very frequently used in a household. The continuous heating, reheating, baking, defrosting, and cooking requires a tremendous amount of uninterrupted energy. This is something that power strips cannot handle.


Coffee Maker or Toasters

They may seem like small appliances, but all that roasting the coffee beans and heating rods for toasting the bread requires a lot of electricity. A power strip cannot provide this, and too much usage could lead to overloading or a potential fire. 



Can I plug an iron into the extension cord?


Although homeowners can use an extension cable to plug in an iron, it’s important to know the significant hazards involved. Safety must always come first if you want to safeguard people and the appliance.

Avoid using a conventional extension cable while using an iron since it is unable to manage the high electrical current requirements of an iron. A heavy-duty extension cord made specifically for such high-wattage appliances should be used instead.

These specialised extension cables are designed to power heavy-duty appliances like irons with plenty of electricity. Any extension cable can be used for this purpose, but doing so risks dangerous situations that could endanger the safety of the entire home.

Can you use an extension cord with an Iron?

The answer is Yes! Using an extension cord with an iron can be done safely, but it requires careful consideration and adherence to safety guidelines. That’s why we have provided below a list of safe steps you can take when it comes to plugging an iron into an extension cord.

Safety Tips for using extension cords with irons

Select the Right Extension Cord: When using an extension cord with an iron, it’s crucial to choose the right type of extension cord. Look for an extension cord that is designed for high-power appliances and has an amp rating that matches or exceeds the iron’s power requirements. Typically, irons require a significant amount of power, so a heavy-duty extension cord is essential.

Check the Gauge: The gauge of the extension cord’s wire is essential. A thicker gauge wire is better for high-power devices like irons because it ensures efficient power transmission and reduces the risk of overheating. It’s recommended to use an extension cord with a gauge of at least 14 or 12 for irons.

Inspect the Extension Cord: Before plugging in your iron, thoroughly inspect the extension cord. Look for any visible damage, such as cuts, frayed wires, or exposed conductors. If you notice any issues, do not use the cord, as damaged cords can be hazardous.

Proper Connection: Make sure to plug the extension cord securely into a grounded outlet. Avoid overloading the extension cord by connecting multiple high-power devices to it simultaneously. An iron should ideally be the only appliance connected to the extension cord to prevent overloading.

Unplug Safely: When you’re finished using the iron, always unplug it by grasping the plug itself and not the cord. Pulling on the cord can lead to wear and tear over time.

Regular Maintenance: Periodically inspect both the extension cord and the iron’s power cord for any signs of wear or damage. Replace any damaged cords immediately to maintain safety.


Can you plug a straightener into an extension cord?

Plugging a hair straightener into an extension cord can be done safely if certain precautions are taken into consideration. You can take a look below at the recommended safety tips you can take when plugging a straighter into an extension cord.

Safety Tips for using extension cords with straighteners

Choose the Right Extension Cord: Select an extension cord that is appropriate for the power requirements of your hair straightener. Look for an extension cord with an amp rating that matches or exceeds the wattage of your straightener. This information can typically be found in the straightener’s user manual or on its label.

Inspect the Extension Cord: Before using the extension cord, examine it for any visible damage, such as cuts, frayed wires, or exposed conductors. Damaged cords should not be used, as they can pose a safety hazard.

Use a Heavy-Duty Cord: Opt for a heavy-duty extension cord with a thicker gauge wire. Thicker wires are better equipped to handle the electrical load generated by high-power devices like hair straighteners. A cord with a gauge of 14 or lower is typically suitable for this purpose.

Plug in Securely: Ensure that the extension cord’s plug fits snugly into a grounded outlet. Loose connections can lead to overheating and pose a fire risk. Always insert the plug fully to establish a secure electrical connection.
