leave the mobile charger plugged into the power even if it is not connected to any device is a widespread habit in many homes. Although at first glance it seems like nothing is happening, this small gesture has an impact on both electricity consumption and home security.
Modern chargers consume a very small amount of power when left connected without charging a phone. This expense is known as standby consumption or “phantom consumption”On average, a charger can use between 0.1 and 0.5 watts when plugged in without any device connected. In a full year, this means very low consumption, normally less than one euro on the electricity bill.
However, the problem increases when all the devices that remain permanently connected are added, such as televisions, computers, small appliances or power strips. Together, these consumptions can represent a more significant part of a home’s energy expenditure.
The risk of overheating and breakdowns
Even if consumption is minimal, leaving a charger plugged in for long periods can pose certain risks.. Good quality chargers are designed to operate safely and have systems that reduce the flow of current when no device is connected.
The danger appears especially with old, damaged or counterfeit chargers, which may not meet safety standards.. These devices can become overheated, short-circuit, or, in extreme cases, cause a fire if they are near flammable materials such as clothing, paper, or furniture.
It is also advisable to avoid leaving chargers connected in places with poor ventilation or covered by objects, since the accumulated heat can lead to device failure.
A simple gesture to save and prevent problems
Energy efficiency experts advise disconnecting chargers when not in use, although they recognize that individual financial savings are small.. The main advantage of this habit is to reduce risks and keep devices in better condition for longer.
In addition, using original or certified chargers, checking that the cables are not damaged and avoiding low quality products are basic measures to improve safety. It can also be useful to use power strips with a switch, which allow you to completely cut off the power to several devices at the same time.
In conclusion, leaving a charger plugged in does not represent a large increase in the electricity bill nor does it represent an immediate danger if it is a safe device and in good condition.. Even so, disconnecting it when not in use is a simple habit that helps save energy, prevent possible accidents and encourage more responsible consumption.
