Many electrical devices continue to consume power even when not in use, leading to wastage and posing fire risks. Properly unplugging devices when you’re not home can help save on electricity bills and ensure your home’s safety.

1. Electronic Devices with Power Supplies: Don’t Let Them “Eat Up Power”

Devices such as TVs, computers, speakers, set-top boxes, phone chargers, and power banks all use power supplies. Even when turned off using a remote control or power button, these devices still consume electricity in standby mode.

For example, a TV can consume 1–3W of power per hour in standby mode. Multiply that by the number of devices and hours per year, and the amount of energy used adds up.

Additionally, in rainy weather or areas with unstable voltage, leaving these electronics plugged in increases the risk of motherboard damage due to issues like lightning strikes spreading through electrical lines. Even a slight "flicker" in the electricity can cause a TV worth thousands of dollars to break down.

Tip: Use a power strip with a main switch to easily disconnect all electronics at once.

2. Kitchen Appliances with Standby Modes: Convenience But Risky

Appliances such as microwave ovens, rice cookers, air fryers, and electric kettles often have LED screens displaying the time or touch buttons, meaning they still consume power even when not in operation.

These heat-generating devices also pose a risk of overheating or malfunctioning relays, which could result in short circuits if the power supply is unstable or there’s a leak.

Statistics from the Fire and Rescue Police Department show that hundreds of house fires annually are caused by household appliances left plugged in for too long without supervision.

Advice: Make it a habit to unplug kitchen devices after each use. If you’re going away for a few days, don’t leave these “time bombs” in your kitchen.

3. Washing Machines, Dishwashers – The Hidden Power Drainers

Many people believe that washing machines and dishwashers don’t consume electricity when not in use. However, these devices often maintain standby modes or Wi-Fi connections, especially the smart models.

Leaving these devices plugged in not only wastes electricity but can also cause the components to become damp, leading to electrical leakage or quicker deterioration.

If you’re going on an extended trip, unplug these devices to save energy and increase their lifespan.

4. Network Devices, Security Cameras: Consider Unplugging If Not Needed

In today’s digital age, many homes have Wi-Fi systems, security cameras, and smart devices that stay connected 24/7. If you’re gone for a short period, leave them operating for monitoring and remote control.

However, for a long trip with no need for surveillance, unplugging the network/camera system or turning off the main power switch will help save electricity and avoid overheating or malfunctions from continuous use.

Note: If your home has a fire alarm system or a theft alarm connected via the internet, ensure that the core system stays active for safety.

Devices You Shouldn’t Unplug

While some devices should be unplugged for energy saving and safety, there are others that should remain connected:

1.  Refrigerator:  If there are still items inside, the fridge should remain on. However, if you’re going away for a long time, clean the fridge, unplug it, and leave the door slightly open to prevent odors.

2.  Air Purifiers, Dehumidifiers: Keep them running if there are young children, elderly people, or prolonged damp conditions in the home.

Conclusion: Small Action – Big Benefits

Unplugging unnecessary devices is a small action that brings great benefits in terms of electrical safety, cost savings, and long-term protection for your appliances.

Getting into the habit of unplugging devices – though it may seem old-fashioned – is one of the most modern ways to prevent risks in your home. Make it a routine for your family to check plugs before leaving the house. A minute of proactive care today can help you avoid a week of worry over preventable incidents.
