The heavy cord swivels 180 degrees so that it can lay flat and out of the way, no matter which way it’s oriented behind furniture.īecause of the SurgeArrest’s size and features, we found it most useful for elaborate entertainment or computer equipment.īelkin has everything covered with this 12-outlet surge protector. The six outlets are spaced nicely to accommodate large power adaptors, and all of them have sliding covers to keep out dust and debris when not in use. There are LEDs to indicate protection status and building wiring faults.

Multiple layers of protection will guard against power surges coming through your coaxial TV cable, telephone/DSL lines, and home’s electrical outlets. Short of using it in a research lab to protect scientific instruments, we had a hard time coming up with a list of equipment to match that total. Amazon Basics 8-Outlet Power Strip Surge Protector, 4,500 JouleĪPC has a lot of confidence in this 11-outlet SurgeArrest, so much so that it offers a $100,000 equipment protection policy.More details about these alternatives can be found at the bottom of our list. While we haven't tested these power strips, they're in stock and are from brands that we trust and have performed well in past tests.

In the event that you find a few surge protectors are out of stock, there are other options that we can recommend. If you need power strip or surge protector, chances are you’ll find one on this list to suit your needs.ĭue to a mix of high demand and supply-chain problems, we've found that some of our favorite power strips come and go out of stock frequently. We used a Sperry Instruments outlet tester to confirm circuit grounding when power strips had wiring fault indicators. We evaluated them based on ease of use, their features, and how they performed in various situations. We plugged these power strips in and tested them in kitchens, family rooms, workshops, and offices. We research the market, survey user reviews, speak with product managers and engineers, and use our own experience with them to determine the best options. The power strips on this list have been thoroughly vetted and evaluated by our test editors. Always check with the manufacturer, they usually provide examples on the packaging of what a certain model can protect. To adequately protect an average home entertainment system or computers and related equipment, look for surge protectors rated in thousands of joules. One joule is about the amount of electricity used to light a one-watt LED for one second. A joule is a unit of energy required to do a certain amount of work. The amount of protection surge protectors provide is measured in joules. However, their need drops off quickly once they’re running, which can cause surges elsewhere in the house’s wiring. Air conditioners, compressors, and electric ranges require a large amount of power, particularly when they start up. The other common cause for surges occurs within your own home. When the power company’s transformers and complex switching systems try to reroute power or address changing demands, it can create inconsistent power flow with dips and bursts. More commonly, power surges are caused during storms when power lines are downed. Most surge protectors can’t handle anything this large, so don’t rely on them during lightning storms-the best way to protect from this type of surge is to unplug your sensitive electronic equipment. People tend to worry most about lightning strikes, which can find their way to electrical wires and cause power spikes in the millions of volts. Power surges can occur due to a number of reasons. So, to be sure you’re getting the most protection you can, it’s a good idea to replace them every two to three years. With every voltage fluctuation they absorb, their lifespan is shortened. What most people don’t realize about surge protectors is that they wear out over time.
