Do you leave the chargers in the socket? You can unconsciously lose money

Is leaving a charger in a socket a mistake? Check if it threatens with fire and how much electricity actually uses the device in standby mode.
In many houses, the chargers remain constantly attached to the sockets – by the bed, desk or in the kitchen. Few users, however, wonder if it is safe and whether they generate hidden costs.
Escaping electricity
Most modern electronic devices, such as smartphones, laptops, watches or headphones, need charging. A typical charger transforms the alternating current from a low -voltage direct current socket, suitable for batteries in devices. To this end, he uses, among others Transformer, filter elements and control system.
Although the charger not connected to the device does not charge, it still draws energy – this phenomenon is referred to as “vampire power” or “wakefulness”. Such energy supplies control systems, and some are distracted in the form of heat. For one charger, this consumption is small, but per year, with many devices, it can translate into significant energy losses.
Modern chargers are designed to minimize power consumption. They are equipped with energy management systems that go into sleep mode and “wake up” only after connecting the device.
Security
However, in addition to energy consumption, security issues are also important. Over time, chargers wear out, especially when the energy network experiences temporary voltage increases. Although modern models have built -in security, cheap and non -cecetic chargers can pose a fire hazard.
Experts recommend that – if possible – disconnect the chargers when they are not used. Particular attention should be paid to their technical condition. If the charger gets unnaturally warm, makes sounds or is physically damaged, it should not be used or left in the socket.
