Energy Efficiency Experts Explain Why Some Appliances, Such as Coffee Makers, Blenders, Irons, Electric Cookers, and Air Fryers, Should Be Unplugged to Avoid Unnecessary Energy Consumption and Accident Risks.
The practice of leaving appliances plugged in all the time can cause more problems than convenience. In addition to increasing energy consumption with what’s known as “phantom load,” this behavior can pose a real risk of household accidents, especially with heat-generating devices.
According to Tiago Reis from the TechTudo portal, extra caution should be taken with devices that use electric resistance, such as coffee makers and irons.
Unplugging these devices is a simple habit that can prevent burns, fires, and extra charges on your electricity bill.

Coffee Maker
Many people forget to unplug the coffee maker even after brewing coffee, but this practice is dangerous. Since it operates with electric resistance, it can accidentally heat up and cause anything from minor burns to the start of a fire.
Moreover, even when off, it consumes energy in standby mode. It is recommended to always store the coffee in a thermos and unplug the coffee maker right after use.
Blender
The blender has low consumption in standby mode, but it can be activated with a simple touch, even when not in use.
This means that leaving the device plugged in exposes users to accidents involving the sharp blades. Unplugging the blender is a practical way to avoid unnecessary risks.
Iron
Among the five analyzed appliances, the iron requires the most attention. Forgetting this device plugged in is one of the leading causes of house fires.
Even models with automatic shut-off do not completely eliminate risks. Additionally, there is the danger of burns and electrical overload. According to Tiago Reis, the rule is clear: “when you finish using it, unplug it immediately.”
Electric Cooker
Practical for everyday use, electric rice cookers or pressure cookers remain in warming mode even after cooking.
Leaving the device plugged in longer than necessary not only consumes energy but also reduces the appliance’s lifespan. The ideal is to unplug the cooker right after serving meals.
Air Fryer
The air fryer has gained popularity for its convenience but also requires care. Although it does not show significant consumption in standby mode, it can be accidentally activated and cause overheating. Unplugging it avoids short circuits and increases kitchen safety.
When Not to Unplug
Despite the recommendations, not all devices should be disconnected.
The refrigerator, for example, needs to stay on 24 hours a day, as turning it off frequently increases consumption and harms food preservation.
Dishwashers, microwaves, and washing machines can remain plugged in for convenience, but in some cases, they can also be unplugged, depending on usage frequency.
Creating the habit of unplugging certain appliances is a simple way to increase safety and save energy at home.
However, not all appliances require this practice, and understanding the differences is essential.
Do you usually unplug these devices after use, or do you leave them all plugged in? Have you ever experienced a safety issue because of this?

Exceto geladeira, TV, forno elétrico e fogão, mantenho todos os eletrodomésticos com as tomadas desconectadas.
Questão de segurança.
Deixar o carregador de celular na tomada gasta e danifica o carregado?
Eu li uma matéria que chaleira elétrica deve ser retirada da tomada após o uso,pois podem dar problemas elétricos e causar incêndio.O que eu faço agora é tirar a chaleira da base todas as vezes que acabo de usar.Antes ela ficava na base e conectada na tomada,agora não mais. Já o microondas dizem que não se deve ficar desligando constantemente da tomada,pois pode ocasionar defeito no aparelho. Não sou especialista na área,talvez uma pessoa com mais conhecimento técnico possa nos dizer se esses procedimentos procedem ou não.
