Safety is another important consideration. Chargers are designed to handle electricity, but constant exposure can lead to gradual wear. Over time, this may increase the chance of overheating, particularly with older, damaged, or low-quality chargers. Although most modern chargers include built-in safety features, unplugging them when not in use reduces unnecessary electrical flow and helps lower potential risks. It also protects chargers from unexpected power surges caused by electrical fluctuations or storms, which can damage both the charger and nearby devices.
