Best surge protectors of 2022

Updated Jun 28, 2022 11:14 PM

Finding the best surge protector for your electronics ensures that they’ll remain guarded from potentially irreversible damage that comes from commonly occurring electrical spikes in building wiring and power grids. Power surges are a normal and inconvenient part of life that occur frequently when utility companies switch electricity on and off again, but they can also be triggered by a variety of electrical events including lightning strikes, storms, and power cycling of large appliances like air conditioners. By placing a surge protector between your electronics and the wall outlet, you can add a layer of safeguarding for your precious appliances that will prevent them from getting fried.

While any amount of protection is better than none at all, it’s important to consider what types of appliances you’ll be using to determine what type is best for your needs. For most common home appliances—like lamps—any standard surge protector should do the trick. But, for high-wattage appliances and critical electronic equipment like computers or stereos, a heavy-duty model may be more fitting. Whether you’re looking for a portable surge protector to use with your electronics while you’re on the go, or one for permanent use in a business or home, we compare some of the best surge protectors currently available to help you make an informed decision, below.

Best heavy-duty: Tripp Lite Isobar 6

Tripp Lite Isobar 6

Why it made the cut: Its super-burly build and military-grade protection can power extremely demanding devices in challenging environments.


  • Protection: 3,330 joules
  • Outlets: 6
  • USB ports: 0


  • Super durable
  • Maximum protection
  • Meets high safety standards


The Isobar from Tripp Lite is a convenient and robust surge protection unit from a power protection industry veteran. It features a six-foot AC power cable and six protected outlets mounted in isolated filter banks to cut down on noise interaction between connected electronics, and three indicator LEDs show users the current protection status and whether there’s a problem in the electrical line. Tripp Lite also offers insurance for connected peripherals, making the Isobar one of the best heavy-duty surge protectors for workshops, garages, and industrial spaces.

The surge protection potential of consumer devices is measured in joules, which is a unit equivalent to one watt applied to an electrical system for one second. A surge protector with a higher joule rating can absorb more energy before failing, which translates to more robust and comprehensive surge protection for critical equipment. If you plan on protecting expensive or sensitive high-wattage electronic equipment like computers, air conditioners, stereo equipment, or power tools, opting for a heavy-duty surge protector with a joule rating of 3,000 or more is a must. That’s what makes the Isobar so appealing to commercial users.

The sturdy metal housing allows this burly surge protector to function properly in demanding environments like workshops and studios without potentially cracking or becoming damaged and jeopardizing your equipment in the process. As an added bonus, it looks as burly as it is.

The GE and similar models are best for stationery use in the home due to less durable casing materials and may not bear the bells and whistles of more expensive units.

The GE model strikes the right balance between performance and reliability for basic jobs.

Features to consider when shopping for surge protectors

Surge protectors are available in portable, bag-sized travel units as well as tough, metal-clad industrial forms and everywhere in between. Determining the best unit for your needs comes down to the level of protection you require according to the quality of the electric system from which you’re pulling power as well as the value of the equipment you’re looking to protect. Whether you’re enduring daily power spikes or just want reliable protection for some extra peace of mind, we’ve picked out a few of the top surge protectors on the market to help you give your electronics the protection they deserve.

Voice control

Voice control, smart home technology, and home automation are more commonplace and accessible than ever before. There are countless smart plug products on the market that allow users to integrate traditional appliances with a smart home system. The best smart surge protectors offer users this same convenient hands-free remote control of their electronics without sacrificing high-level protection from power surges all in a single unit.

Most smart surge protectors offer compatibility with Alexa, Google Home, and other popular smart home systems, but many are able to function as standalone units as well. A local WiFi network and a companion app are usually all it takes to get up and running, turning a smartphone into a universal remote for your electronics. Users who want to create automated lighting schedules or who want to activate coffee makers, slow cookers, and other devices from afar will appreciate the combination of convenience and safety that a smart surge protector provides. These may not be the most robust choice for heavy-duty applications, but they’re completely unparalleled for adding flexibility, protection, and voice control to commonplace household and office appliances.

USB ports

You don’t always have to find a charging brick when you want to plug in your phone or other portable device. Some surge protectors have built-in USB connectivity, which allows you to charge extra devices without having to occupy one of the AC sockets. These can come in handy even when you might not expect it. For instance, USB ports can be handy for charging controllers if you have them on the surge protector in your home theater.

Outlet arrangement

If you’re going to be plugging in big power bricks, there’s a chance you might run into a traffic jam that prevents you from using all of your surge protector’s real estate. Try to visualize the plugs you need it to accommodate and make sure there’s room for everything. Otherwise you’ll be trying to daisy chain strips together and that’s not good for anything.


Q: How many joules are in a good surge protector?

The best surge protectors can range anywhere from around 800 joules up to 4,000 joules and beyond. Determining which level of protection you need depends largely upon the value of the equipment you’re protecting as well as the known reliability of the electrical system that you’re using, but when in doubt, the more joules the better.

Q: What is Type 1, Type 2, and Type 3 surge protection?

The most common form of surge protection offered by consumer products is Type 3 surge protection, which is used in parallel with consumer electronics at the load end of an outlet. Type 1 protection is a permanent installation that protects the whole electrical system from outside sources of surges including lightning strikes and utility switching, while Type 2 protection is a permanent installation that protects from surges caused within a system, as in the case of air conditioners or other large appliances.

Q: How often should I replace my surge protector?

Surge protectors offer diminishing protection over time, but fortunately, the best surge protectors actively indicate whether your electronics are protected or not. As a rule of thumb, you can wait three to five years before replacing a surge protector, but users with frequent power issues—including lightning strikes, rolling blackouts, or brownouts—will have to replace their surge protectors more often.

A final word on shopping for the best surge protector

Surge protection doesn’t come standard in most buildings and power systems, so it’s crucial to ensure that your electronics are safeguarded from inevitable power spikes and blackouts with the best surge protector for your needs. Home users should turn to a smart surge protector for total control over their electronic ecosystem or a surge protector with USB ports for quick charging and protection of their irreplaceable devices, while commercial users who need robust protection should turn to a heavy-duty surge protector to keep their bases covered. Whether you’re powering a vacuum cleaner or a smartphone, every user of electronic equipment big and small should use a surge protector. Then you can rest assured that your devices are safe and sound the next time a blackout or power surge comes around.
