What is the function of a surge protector?

A surge protector is designed specifically to safeguard electronic devices from the damaging effects of power surges or spikes. When there is a sudden increase in voltage, often caused by events such as lightning strikes, power outages, or the sudden switching on/off of high-powered devices, a surge protector works by redirecting the excess voltage away from connected devices, effectively absorbing or dissipating the additional electrical energy. This protection helps to prevent potential damage to sensitive electronics like computers, televisions, and gaming consoles, which could suffer from data loss or hardware failure if subjected to these voltage spikes.

While some surge protectors may also offer additional features like surge suppression ratings or be designed to provide extra outlets, their primary and most critical function remains as a protective device against voltage surges. Factors like boosting internet speed or improving wireless signal strength are unrelated to the role of a surge protector, as these tasks pertain to different areas of electronic functionality, such as networking equipment or wireless technology.
