What is a power surge?« Back to Questions List

A power surge happens when something causes a spike in the amount of electrical charge flowing through power lines, which can go through the current leading to your wall outlet. The most well-known cause of power surges is lighting, however, the most common cause is actually high-power electrical devices. Appliances such as refrigerators or air conditioners require a lot of power, so turning them on can cause a quick surge in electrical charge. Whether a power surge is caused by a lighting storm or high-power appliances, it can be very damaging to anything plugged into the outlet at the time of the surge. Whether gradually or immediately, the overload of electricity flowing into your electronics can overpower them and cause hundreds or thousands of dollars’ worth of damage.
