Power chargers are an integral part of our daily lives, as we use them to charge our phones, computers, smart watches, and many other devices.
But experts warn of unexpected dangers lurking inside the chargers of the devices we use every day. While we may think these small devices are harmless when left plugged in, data shows they can turn into veritable "vampires," straining our electricity bills and threatening the safety of our homes.
According to experts, inside every charger lies a complex world of electrical circuits that convert alternating current (AC) from the electrical outlet into low-voltage direct current (DC) suitable for our devices. This process requires several electrical components such as transformers, switching circuits, and filter elements.
Direct current is characterized by the movement of electrons in one direction within the circuit, while in alternating current, electrons move back and forth without rotation.
Electricity is generated using alternating current, but modern devices require direct current, which requires an AC-DC converter in almost every device.
The real problem lies in what's called "phantom power consumption" or "vampire power." When you leave your charger plugged in, it continues to consume a small amount of power to keep its control and protection circuits working, while the rest is lost as heat. While the consumption of a single charger may seem small, the combined power consumption of all the chargers in your home can add up to hundreds of kilowatt-hours wasted over the course of a year.
But the danger isn't limited to energy waste. Chargers, especially cheap and uncertified ones, can pose a real risk. Constant exposure to voltage fluctuations can damage the charger's internal components, increasing the risk of electrical shorts or even fires. Therefore, if you notice your charger getting unusually hot or making strange noises, it's time to replace it immediately.
The ideal solution is to unplug chargers when not in use, especially at night or when leaving the house. It's also recommended to use high-quality chargers from certified companies, as these feature advanced protection systems and consume less power in standby mode. This way, you not only protect your home and devices, but also save on your electricity bill and contribute to environmental protection.
