9 Things to Never Plug into a Power Strip

Plugging electrical appliances into power strips can be convenient and cost-effective, but it’s important to be aware of the potential risks involved.

Devices that consume a lot of energy or overloading a power strip can cause serious issues. These can include damaging appliances, causing power outages, or even starting fires. Here’s a personal story: it’s happened to me, and since then, I’ve been extremely cautious.

Let’s explore the nine devices you should never plug into a power strip.

First, Check the Power Strip’s Maximum Capacity

Before delving into what not to plug in, you need to understand the power limits of your power strip. The maximum power it can safely handle is usually indicated on the power cable.

Make sure to check this information and add up the power rating of each device you plan to plug into the power strip. For example, if your power strip supports up to 3500 W and you plug in an oven (2500 W), a vacuum cleaner (800 W), and a kettle (250 W), you exceed the limit with a total of 3550 W. In this case, you should unplug one item to stay below the threshold to avoid dangers.

1. The Oven

Ovens are among the most energy-hungry appliances. Even if you don’t use it daily, it’s crucial not to plug it into a power strip. Instead, use a dedicated wall outlet to prevent the risk of overheating.

2. The Refrigerator

Although a refrigerator doesn’t consume as much energy as some other appliances, it’s always running, sending electrical voltage to the power strip 24/7. This constant demand can cause overheating, so it’s best to plug it directly into a wall outlet. This applies to both refrigerators and freezers.

3. The Washing Machine

A washing machine typically consumes around 1150 kWh per year, making it a high-energy device. Plugging it into a wall outlet rather than a power strip minimizes the risk of short circuits and overheating. This advice also extends to tumble dryers for the same reason.

4. Auxiliary Heating

Auxiliary heaters should never be plugged into a power strip because they can quickly overload it. Always use a wall outlet for safety.

5. The Microwave

Despite its small size, a microwave can consume around 70 kWh per year. It’s best to avoid plugging it into an extension cord.

6. The Coffee Maker

Coffee makers might seem small but they are surprisingly energy-intensive, consuming an estimated 165 kWh per year. Therefore, they should be plugged directly into a wall outlet.

7. The Toaster

If you toast bread daily, your toaster can consume between 500 and 1000 W per year. Due to its high energy consumption, it’s best not to plug it into a power strip.

8. Another Extension Cord

Using multiple extension cords connected to each other can easily exceed the power strip’s maximum capacity. This is a hazardous practice and can lead to domestic fires.

9. The Internet Box, Computer, and TV

Although these devices don’t consume a lot of electricity, they are sensitive to electrical issues like overvoltage. It’s better to avoid using a power strip for these devices or invest in a surge protector.

In conclusion, understanding which devices should not be plugged into a power strip can reduce the risk of overheating and fire. While the chances of such incidents are low, it’s better to be safe than sorry.
