Does Your Smart TV Need a Surge Protector? What You Need to Know!

Generally, a smart TV needs a surge protector since the power surge can easily damage the sensitive electronic circuits of a television. With an inexpensive surge protector, you can enjoy peace of mind and safeguard your television and other expensive electronic devices.

The term “power surge” sounds like trouble, even if you can’t quite grasp its meaning. When you throw your expensive smart TV into the same sentence, you’ll end up with a nagging question that can keep you up at night.


As per data on power surges, I found that most homes experience an average of six power surges per day which comes to around 2000 power surges a year. 

If your home electronic devices are not protected from these power surges, these spikes will damage sensitive electronic circuits used in televisions, computers, telephones, and other home entertainment equipment.

In this article, we dive deeper into what surge protectors do, why you should buy one for your precious TV and more!

Why Your Smart TV Needs a Surge Protector?

Why Your Smart TV Needs a Surge Protector

Before we discuss why a surge protector is a must for your TV, let’s quickly go over how it works.

As the name suggests, this nifty piece of equipment absorbs excess voltage that may result from a power surge. After that, it directs this extra power toward the ground wire so that it doesn’t hit your electronic devices.

Remember that power surges happen often, and not just when the electricity comes back on after going out. A power surge accompanies several scenarios, including:

  • A blown transformer
  • Air conditioner or refrigerator motor pausing or working again
  • Lighting strikes on utility equipment

But what happens if you leave your smart TV unprotected in the face of a power surge?

Well, if you couldn’t unplug your TV before a power surge (and it’s not always predictable), the odds may not be in your favor. The fluctuation in voltage from a power surge can seriously harm the microprocessor in your TV if it’s a strong one.

Even small power surges could negatively affect the sensitive internal parts of the TV over time. 

Your TV won’t stop working straight out, of course, but it might develop electronic rust. As a result, its performance will go down more rapidly, shortening the lifespan of your pricey TV.

Experts even claim that allowing your devices to face multiple power surges might lead to losing your data. No one wants to deal with such an annoying situation!

3. Nuetsa Flat Plug Extension Cord and Surge Protector

Our final recommendation is the Nuetsa surge protector for people who want a middle ground between the previous two products. 

It features eight AC outlets and four USB charging ports that include a USB-C option and smart charge support. Not just that, you may also use it on 120v to 240v circuits!

Lastly, this highly-rated power strip boasts a minimum 2700 joules absorbing capacity. In other words, it is one of the most reliable surge protectors on the market.

How Long Is a Surge Protector Good for When Used With a TV?

The thing about surge protectors is that they get worn down the more power surges that they deal with. The more joules they endure, the fewer future joules they can divert away from your TV.

For this reason, it’s best to replace your TV surge protector every three years. 

Thankfully, many protectors on the market come with an LED that gives you an idea about the joules of protection available. So, monitor this indicator to know when to replace your device.

What Are Other Electronic Devices That Need a Surge Protector?

Smart TVs aren’t the only electronic devices you must pair with a solid surge protector to prevent their circuits from being fried after a power surge!

As a general rule, all appliances and devices with microprocessors are susceptible to damage due to power surges. 

This is why it’s a good idea to plug the following devices into surge protectors, too, to increase their lifespans:

  • PCs and laptops
  • Phone chargers
  • Routers 
  • Gaming setups and systems
  • Medical equipment
  • Any smart or computerized devices within your household

Which Devices Don’t Need Surge Protectors?

Most devices that don’t feature a sensitive microprocessor within their systems can do fine without a surge protector. For example, alarm clocks, coffee pots, vacuum cleaners, and the like fall into this category.

More interestingly, others with high power capacity are a big no-no, like microwaves and space heaters. You must plug these devices right into the wall outlet.

How Many Volts Are There in a Typical Power Surge? 

Typically, there is around 169 volts in a residential power surge, for a commercial system it can be around 1,000+ volts. 

For example, in in North America power outlets have 120 volts circuits.
