Despite not having a considerable consumption like the electric shower, for example, this habit generates an expense in the electricity bill At the end of the month. Likewise, he raises a question about conscious consumption of electricity.
Current chargers are configured to have more power and consume less electricity. However, when plugged in unnecessarily, they continue to consume a small amount of electricity on a daily basis.
Chargers are manufactured by different companies, so they have some variations in consumption. However, the average consumption of the charger is 0.1 to 0.5 watts in standby or stand by mode.
To exemplify consumption, professor of electrical engineering at the Mauá Institute of Technology (IMT) Alessandro de Oliveira Santos explained on the Tecnoblog news portal that: “In practice, it is a stand-by consumption well small. For example, considering a value of BRL 0.74 per kWh, you would spend BRL 0.60 per year with the charger connected to the socket without being used — it is very little”.
The professor also reinforced that the values may vary according to the size of the smartphone, notebook or mobile device. In addition, the electricity utility tariff is also a factor that influences the final bill.
In general, consumption is not high, but the increase in the amount of equipment and mobile devices that are used daily encourages the habit of never removing the charger from the socket.

Despite the low financial impact, the habit of leaving the charger connected reflects negatively on the safety of children and animals in the home, as well as on the conscious use of electricity.
Therefore, it is important to reflect on the need to leave equipment, such as chargers, plugged in when not in use.
If your focus is on saving energy, changing one more habit like this is a good way for your awareness of energy consumption.
Another important step is to purchase energy-efficient and certified chargers to ensure your safety and low consumption of the product in standby mode.
