Do you also plug your hair dryer into an extension cord? ⚡💨 Don’t do that! Turns out, you really shouldn’t—and I only found out when I was 30. 😳🙈 After that incident, I decided to write an article about what else you should never plug into an extension cord. ⚠️🔌 While you read, I’ll go tell my wife about the hair dryer… 😅 And if you know any other risky appliances, let me know! Enough talking—let’s get to the point. The full article is below! 📖👇
In today’s world, home appliances make life significantly easier, and manufacturers continue to develop more advanced models to handle everyday tasks. However, not every home has enough power outlets to accommodate all these devices, leading many people to rely on extension cords. Even though they seem like a practical choice, not all appliances should be plugged into them. Here’s why some devices pose serious risks when connected to an extension cord.

1.Refrigerator and Freezer
Large-capacity kitchen equipments like fridges and freezers run continuously and require a stable power source. Plugging them into an extension cord may result in voltage fluctuations, diminished productivity, and even potential damage due to power fluctuations. If absolutely necessary, only use a high-quality surge-protected extension cord and avoid plugging in additional high-power devices.
2.Microwave Oven
Microwaves demand substantial energy to operate, often drawing as much power as an electric stove. Some models even surpass the energy usage of a washing machine. If a separate outlet isn’t available, ensure that the extension cord is heavy-duty and that no other high-power appliances are running on the same circuit.
3.Coffee Machine
Like most devices that produce heat, brewing machines require a high level of electricity. While they are typically used for short periods, they can still overheat an extension cord if multiple appliances are running at the same time. If an extension cord must be used, be sure to power only one appliance at a time.
4.Toaster
Toasters, waffle makers, and pancake griddles heat up quickly and put an instant high load on the electrical system. Plugging them into an extension cord can cause overheating, which increases the risk of melting wires or even electrical fires. It’s always best to plug these devices directly into a wall socket.
5.Slow Cooker (Multicooker)
Despite being considered a low-energy appliance, a slow cooker operates for extended periods. This prolonged use can lead to overheating if connected through an extension cord. If no other option is available, ensure that all other appliances are unplugged before using the slow cooker with an extension.
6.Hair Styling Tools
Hairdryers, curling irons, and straighteners may be small, but they draw a lot of power and heat up very quickly. When plugged into an extension cord, this could cause the cord to get excessively hot, potentially leading to short circuits or electrical fires. Manufacturers specifically warn against using these tools with anything other than a direct wall outlet.
7.Heaters and Air Conditioners
Heating and cooling appliances are some of the riskiest devices to plug into an extension cord. Temporary heating units, in particular, are a major cause of electrical fire incidents in the winter due to improper use. A top-tier extension cord still cannot guarantee safety when dealing with such high power loads.
Holiday Lights and Decorations
While not an appliance, it’s important to mention that plugging multiple string lights or holiday decorations into an extension cord—especially if daisy-chaining multiple cords together—is a major fire hazard. Always adhere to the manufacturer’s instructions and use extension cords meant for outdoor environments or holiday lighting.
Never daisy: refrain from joining several extension cords in a series.
Consistently monitor for signs of overheating, wear, or any damage before using an extension cord.
In case you spot flickering lights or a warm cord, unplug immediately and use a dedicated outlet instead.
When in doubt, the safest option is to get an electrician to add more outlets for appliances that consume a lot of energy.
Improper use of extension cords can be a serious hazard; always ensure that safety is your number one concern. when setting up your household electronics.
