How does surge protection work?

Surge protectors are devices that detect voltage spikes and divert excess electrical energy away from your devices. They use a variety of methods to accomplish this, the most common being a metal oxide varistor (MOV) technology. MOV-based surge protectors have a metal-oxide component that allows them to absorb excess voltage by diverting it to a grounding wire. This helps to prevent the surge from reaching your devices and potentially causing damage.

Why is surge protection important?

Surge protection is essential because it provides a safety net for your electrical devices against potential voltage fluctuations. Power surges can occur due to lightning strikes, electrical grid issues, or even sudden power restoration after an outage. Without surge protection, these voltage spikes can wreak havoc on your devices, leading to expensive repairs or replacements. Surge protection acts as a barrier, safeguarding your valuable electronics from the harmful effects of power surges.

How does surge protection relate to wall chargers?

Wall chargers are commonly used to charge our smartphones, tablets, and other electronic devices. Since these devices are highly susceptible to voltage fluctuations, surge protection in wall chargers becomes crucial. By choosing a wall charger with built-in surge protection, you can ensure the safety of your devices while charging. This added protection eliminates the risk of potential damage caused by power surges during the charging process.
