Smart Home: Unplug These 5 Devices to Protect Your Home and Your Wallet

Many household appliances are simply turned off with the push of a button after use. This seems like a safe and sufficient solution. However, a surprising number of devices still consume electricity even when they are in “off” mode. This phenomenon, known as phantom or standby power, can account for up to 10% of your monthly electricity bill, according to studies.

In addition to being an unnecessary expense, some appliances that are always plugged in can also pose a safety risk. This article identifies five devices that you should always unplug after use. This simple habit can go a long way toward making your home safer and saving energy.

What is phantom power and why does it matter?

Phantom power  (sometimes called “vampire power”) is the electrical energy that electronic devices and appliances draw when they are turned off but still plugged in. They use this energy to power small functions such as LEDs, internal clocks, remote controls, or quick start.

Common examples and their impact:

• Chargers (mobile, tablet): 2–5 W

• TV and set-top box: 3–10 W

• Microwave with clock: 3–8 W

• Coffee machine with display: 1–5 W

Although the individual values ​​seem low, in total and when operated continuously 24 hours a day, they represent a loss of tens to hundreds of euros per year. However, saving money is only one side of the coin. The other, often more serious, is the potential security risk.

Appliances #1: Bathroom beauty appliances (hair straighteners, curling irons, hot brushes)

These appliances operate at very high temperatures, often exceeding 200°C. Even when switched off, internal components can retain heat for some time. Damaged insulation, failure of the automatic switch-off with the lid or unintentional activation can lead to a fire, especially if the appliances are left on a flammable surface (cloth, wooden furniture).

Recommendation:  Unplug the appliance from the socket immediately after use and place it on a heat-resistant mat until it has cooled completely.

Device #2: Portable space heaters

Heaters are among the largest consumers of energy in the home (up to 1500 W). Their main threat is the intense heat they emit. They should never be left unattended, during sleep or near curtains, bedding or furniture. Even when switched off, a heater that is still plugged in can pose a risk in the event of accidental switching on or an electrical fault.

Recommendation:  Always unplug the heater when leaving the room or at night.

Appliance #3: Toasters and small ovens

These appliances contain exposed hot elements. Leftover bread crumbs or food can accumulate inside and ignite during further use or due to residual heat. A plugged-in appliance is always under a certain electrical voltage, which increases the likelihood of a fault.

Recommendation:  Unplug the appliance after use and regularly clean it of spilled crumbs. Store it in a cool, dry place.
