A typical surge protector passes the electrical current along the outlet to number of the devices plugged into the power strip. If the voltage happens to rise above the acceptable level, the protector will divert the extra electricity into the outlets grounding wire.
Do surge protectors really do anything?
Surge protectors offer protection in units called joules. Generally, the more joules the better, as this means the device can handle one large surge, or multiple smaller surges, before your gear is in danger. Over time, the parts inside the protector wear down, reducing its effectiveness.
What Does a surge protector protect you from?
A surge protector is more than just a power strip to give you additional useable outlets; it is an affordable way to protect your electronics from random power surges that can cause permanent electrical damage.
What’s the difference between a surge protector and a power strip?

How long are surge protectors good for?
Yep, that’s right: Surge protectors don’t last forever. Most estimates put the average lifespan of a surge protector at three to five years. And if your home is subject to frequent brownouts or blackouts, you might want to replace your surge protectors as often as every two years.
How do you know if it’s a surge protector?
How can you tell the difference? Surge protectors will have a rating in Joules of energy showing the maximum voltage it can handle from a power spike. You can find those numbers on the box or strip itself. If there are no numbers listed, it is just a power strip.
What should you not plug into a surge protector?
Avoid starting an electrical fire by never plugging these items into a power strip. Large Kitchen Appliances (Refrigerator, Dishwasher, etc.) These appliances are so high-powered that they’ll easily overload a poor, little power strip. Small Kitchen Appliances. Hair Styling Tools. Extension Cords and Other Power Strips.
What should I look for when buying a surge protector?
A higher joule rating is the best indicator of greater protection. Choose a surge protector with a joule rating at the very least in the 200 to 400 range. Sensitive or costly equipment, such as computers, displays and audio/video equipment, warrants a joule rating of at least 1000.
Should my refrigerator be on a surge protector?
We do not recommend connecting a refrigerator or freezer to a surge protector. The reason we do not recommend this is explained below: The compressor is sensitive to temperature and current overloads and will shut itself down with a power surge.
Do kitchen appliances need surge protector?
However, surge protectors are a good idea if you have an off-grid power system or use a generator. These are much more prone to sudden surges, so surge protectors are needed, especially with appliances that are more sensitive to surges, such as computers and medical equipment like CPAP machines.
Will a power surge damage my refrigerator?
When there is an increase in voltage from a power surge, it causes an inrush of electrical current within the refrigerator. This surge generates an excessive amount of heat, which can damage multiple parts of the refrigerator. A voltage surge can also damage the refrigerator’s ice maker.
Does a laptop need a surge protector?
Using surge protectors is highly recommended for your laptop. A power surge could easily damage your laptop because it’s filled with voltage-sensitive parts. Laptops aren’t designed to withstand violent power surges. Although they may survive for a while, a surge protector will extend their lifespan.
Does Smart TV need surge protector?
Desktop computers, laptops, televisions, gaming systems, and charging phones should all be plugged into a surge protector, so they aren’t damaged in a storm.

Should I turn off my surge protector at night?
Turning off the power strip has no negatives / no positives. Turning off your devices has both positive and negative impacts obviously even the small amount of electricity used in sleep mode has a cost.
Do surge protectors work without ground?
Grounding is a critical element required for proper surge protection. In regard to the question about whether surge protectors work on ungrounded outlets, the answer is “no.” Surge protection equipment typically uses components called metal oxide varistors (MOVs) to divert excess current into the ground line.
Do surge protectors work against lightning?
Do surge protectors work against lightning? Surge protection does offer enhanced protection when lighting strikes. However, surge protectors alone cannot 100% protect your devices. The only way to ensure 100% protection is to unplug everything.
Do surge protectors use more electricity?
The answer? No, surge protectors themselves don’t “drain” energy. They simply monitor the amount of electricity flowing into the appliances they protect and absorb extra voltage if and when it comes along.
Do phones need surge protection?
You don’t need a surge protector for all electronics, but the devices do act as cheap insurance for your expensive tech gear. They can also add features to your setup, especially when you spring for an uninterrupted power supply/surge protector combo.
Can a power surge damage appliances?
Most appliances and electronics used in the United States are designed to be powered by this form of generated electricity. But during a power surge, the voltage exceeds the peak voltage of 169 volts. A spike in voltage can be harmful to appliances and electrical devices in your home.
How common are power surges?
Internal power surges are the most common type. More than 50 percent of household power surges are of this variety. They may occur dozens of times every day. Most power surges are too small to be detected by the human senses and not strong enough to interrupt electrical service.
What is the purpose of a power surge protector?
A typical surge protector passes the electrical current along the outlet to number of the devices plugged into the power strip. If the voltage happens to rise above the acceptable level, the protector will divert the extra electricity into the outlets grounding wire.
