A surge protector is a device designed to protect electrical appliances from voltage spikes, commonly known as power surges. These surges can occur due to various reasons, such as lightning strikes, power outages, or sudden changes in electricity usage. By diverting excess voltage away from connected devices, surge protectors help prevent damage to sensitive electronics like computers, televisions, and home appliances. Surge protectors come in various forms, including power strips with built-in surge protection and standalone units. They are rated by their ability to absorb energy, often measured in joules. Investing in a quality surge protector can extend the lifespan of your devices and safeguard your home from electrical damage.
