If you keep the charger plugged into an outlet repeatedly, it will overheat, accelerating the wear of its internal components, such as capacitors. In the event of a sudden change in voltage, the charger connected to the mains may overheat and begin smoking, perhaps resulting in a fire.
It’s also critical to make your home secure, particularly if you have young children. A charger plugged into an outlet with a cord attached may provide a risk of electric shock.
