Surge Protection: Why Your Tech Needs It

Surge Protection: Why Your Tech Needs It

Protecting your electronics and high-end devices against damage from power surges is a must. Learn about potential threats, best practices, and how shockingly easy it is to invest in surge protection, so your devices work without the worry.

Overview

In inclement weather conditions, there can be a surge in lightning strikes, power spikes, and events causing outages. In the U.S., July through September are months where storms occur most frequently, but that’s a moving target extending well into October. Domestically, Michigan has the highest number of outages per capita, and other states prone to outages include Ohio, New York, Texas, and California.

To prevent damage to devices in unpredictable weather, Belkin offers premium, tested, and certified products to protect your electronics and appliances. Our surge protectors are best-in-class and portable chargers keep you connected whether you’re working in a large office, at home, or own a small business that relies on consistent power.

What is a Power Surge?

The term “power surge” refers to a spike in voltage that elevates a device’s electric flow past its designated threshold. A power surge can be categorized in one of two ways:

  • Internal: an internal surge is common within households, occurring when a motorized device (e.g., an air conditioner or refrigerator) suddenly and unintentionally shuts off. This electricity is then directed to other appliances attached to the same power grid. Essentially, anything plugged into an outlet within the same place is at risk for absorbing this electricity and surging.
  • External: an external surge is caused by an external force, such as a lightning strike or an animal tampering with electrical wiring.

In both instances, our surge protectors work by diverting the extra electricity into an outlet’s grounding wiring, saving the connected devices from absorbing this excess power and overheating or short-circuiting.


Although commonly referred to as a surge protector, other names include spike suppressor, surge suppressor, surge diverter, surge protection device (SPD), or transient voltage surge suppressor (TVSS).

Surge Protector vs. Power Strip

A power strip is essentially an extension cord using one plug to provide multiple outlets. While basic power strips conveniently provide extra outlets, they don’t protect devices if the power strip doesn’t have surge protection components.

A surge protector has more components, and it defends against possible voltage surges and spikes that could damage your electronics, appliances, or equipment. Common causes of voltage spikes include electrical overloads, lightning, faulty wiring, and power outages. One of the extra components in a surge protector is a Metal Oxide Varistor (MOV) designed to clamp at a specific voltage (typically over 340VAC). Belkin surge protectors differentiate from others by clamping and starting to protect at around 340VAC. Many budget or lower quality surge protectors don't clamp or kick in until higher voltages of 500VAC or higher are reached and by then electronic devices could already be damaged.

MOVs are prevalent components used to protect AC power circuits, but over time they can degrade. As they absorb electrical surges, they get used up. It’s more cost effective and convenient to replace surge protectors versus expensive electronic equipment that may get damaged if left unprotected.

Surge protectors offer protection in measurements called joules. A surge protector with a higher joule rating is more capable of protecting against a single big surge or a series of smaller ones. Additionally, most surge protectors have an indicator light that glows to show when devices are protected and a reset button that needs to be pressed for over-current protection after an event occurs.

Similar in look but different in function, power strips are commonly mistaken for surge protectors.

Safety Guidelines for Surge Protectors

Observing basic safety guidelines minimizes potential risks for device malfunction. Precautionary measures include (but are not limited to):


  • Always use our surge protectors indoors in a dry, temperature-controlled location
  • Do not exceed the electrical rating of the product
  • Do not use our surge protectors with aquariums or other water-related devices and machines
  • Uncoil the cord before use
  • Do not cover the cord with any material
  • Keep children and pets away
  • Do not plug a surge protector into an extension cord, also called “daisy chaining”

Replacing a Surge Protector

Replacing a surge protector after a power surge event, for example, a lightning storm, is key. When a power surge occurs, our surge protector’s joule capacity will likely take a big hit, making the device less effective. Even without a major power surge, a good rule of thumb is to replace our surge protectors every two years.


In addition to using our surge protectors properly and effectively, taking small proactive steps to prevent internal power surges is also key to ensuring the safety of devices. While external power surges are somewhat unavoidable, internal power surges can be curbed.

A Few Tips to Prevent Internal Power Surges

  • Unplug devices that aren’t in use.
  • Periodically upgrade wiring.
  • Plug large devices into separate power sources.
  • For example, do not plug a dishwasher and refrigerator — two major electricity absorbers — into the same outlet.
  • Use our surge protectors throughout a space, especially one in which many tech devices are operating.

Key Specs to Pay Attention to When Purchasing

It pays to research specs before you buy a surge protector that will meet your needs. Weighing features means delving into the reliability, brand reputation, and warranty of a specific device. Here are 7 key specs to pay attention to when you’re in the market for a quality surge protector.
