Connecting your electronics to the proper surge protector will ensure they remain guarded against potentially irreversible damage from commonly occurring electrical spikes in building wiring and power grids. While any amount of protection is better than none, 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. However, a heavy-duty model may be more fitting for high-wattage appliances and critical electronic equipment like computers or stereos. 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’ve compared the best surge protectors to help you make an informed decision.

The best surge protectors: Reviews & Recommendations
Power surges are a normal and inconvenient part of life and frequently occur when utility companies switch electricity on and off again. Various electrical events—including lightning strikes, storms, and power cycling of large appliances like air conditioners—can also trigger them. By placing a surge protector between your electronics and the wall outlet, you can add a layer of safeguarding for your precious appliances to prevent them from getting fried. One of our choices is an invaluable accessory for your priceless setup.
Best overall: Monster Power Center Vertex
Why it made the cut: Monster’s surge protector is the ideal combination of utilitarian and forward-thinking design.
Specs
- Protection: 3,000
- Outlets: 6
- USB ports: 3
Pros
- Solid protection
- USB ports on a removable puck
- Braided power cord
Cons
- Only one USB-C port
Monster’s Power Center Vertex is a six-outlet surge protector that does more than just keep your devices safe from damage during power surges or brownouts. A hexagonal puck, attached to the surge protector with a red braided cable, contains two USB-A and one USB-C port. The cable is long enough that you’ll be able to keep it on top of a desk while the Power Center Vertex sits on the ground, and it can be coiled around the surge protector when you’re not using it. We moved around this USB puck quite a lot during our tests, and it showed no signs of damage despite being twisted and turned quite a bit. The surge protector’s power cable is also thick, braided, and felt sturdier than other companies’ PVC or plastic-covered cabling.
The Power Center Vertex offers 3,000 joules of protection for larger electronics like laptops, TVs, and printers. An eight-outlet version called the Power Vertex XL is available for $20 more and offers 5,000 joule protection. We used the Power Center Vertex to power projectors, game consoles, wireless chargers, and other desk accessories simultaneously and never had any trouble. We were especially fond of the USB hub, which can be attached to your wall using an included adhesive magnetic plate. It would have been nice for the hub to include more than one USB-C port, but it freed all our outlets up for more important gear. If you need an all-in-one power solution for your home office or living room, we recommend Monster’s Power Center Vertex.
Best splurge: Austere VII Series Surge Protector Power Strip
Why it made the cut: Austere’s well-crafted surge protector offers both ample protection and aesthetics.
Specs
- Protection: 4,000
- Outlets: 8
- USB ports: 5
Pros
- Premium design
- Multiple USB-C and USB-A ports
- High number of outlets
Cons
- Price
Austere’s VII Series Surge Protector Power Strip offers higher-than-average protection in a solidly built metal enclosure. We tested the eight-outlet model, though a six-outlet option is available for $20 less. Both surge protectors in Austere’s VII series have the same sharp-looking exterior, joule protection, and five USB ports built into one side. We were especially pleased that there were three USB-C ports (one offering up to 45W of power output) in addition to two USB-A ports. You shouldn’t have to plug a charger into an outlet to keep your devices topped up. Three indicator lights beside the surge protector’s outlets indicate it works properly.
We used the power strip surge protector in a couple of configurations—on the floor and attached to a wall using 3M strips, as seen in the photo above. This was possible because this heavy-duty surge protector comes with a long cord. During our tests, we experienced several power outages, and the surge protector kept our electronics safe. All the surge protector’s outlets were in use, providing power to a 4K TV, all three current-generation game consoles, an AV receiver, a media streamer, and even a CD player. All of these devices were attached during our last power outage, and all continue to function perfectly. It may be pricier than our other recommendations, but Austere’s VII Series Surge Protector Power Strip is well worth the investment to protect your most premium gear.

The ubiquitous USB charging port is used to power everything from portable hard drives to cellphones, making it a popular outlet choice for inclusion on power strips and aftermarket wall outlets. Buying a surge protector with USB ports allows users to give their smartphones protection that traditional wall chargers and power strips don’t offer. It’s always nice to have peace of mind when charging a phone, and it ensures you won’t be stuck with a bricked device in the event of a power surge. These also eliminate the need for users to keep track of their wall chargers, which can often go missing, allowing them to plug straight into the surge protector. This is especially handy when you’re in a college dorm situation where multiple people may need access to charging capabilities, which is why it is our pick for the best surge protector for college dorms.
Users looking to charge numerous peripheral devices and enjoy the benefits of surge protection won’t have to skimp on normal three-pronged outlets with this GE UltraPro 10-Outlet Surge Protector. Its 10 grounded outlets and two USB ports offer 3,000 joules of surge protection to devices in multiple plug orientations, making it a good option for shared spaces and desk areas with many devices to power. You can choose between 3-, 4-, and 6-foot cord lengths depending on the layout of your space. It’s the perfect model for shared use in a common room.
A pair of slotted holes on the back of the device makes it easy to mount to a desk or wall to secure it down, and you won’t have to worry about someone walking off with it next time there’s a party, or people come over.
Best heavy-duty: Tripp Lite Isobar 6
Tough As Nails
Why it made the cut: Its super-burly build and military-grade protection can power extremely demanding devices in challenging environments.
Specs
- Protection: 3,330 joules
- Outlets: 6
- USB ports: 0
Pros
- Super durable
- Maximum protection
- Meets high safety standards
Cons
- Bulky
- No USB
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 reduce noise interaction between connected electronics. Three indicator LEDs show users the current protection status and whether there’s a problem with 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, 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, translating 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 a bonus, it looks as burly as it is.
Best for TVs: APC Wall Outlet Plug Extender
Unassumingly Small
Why it made the cut: Its flat form factor makes it easy to tuck behind an entertainment center or TV stand where it can keep many cords in order.
Specs
- Protection: 1,080 joules
- Outlets: 4
- USB ports: 0
Pros
- Slim design
- LED that illuminates when faulty wiring is detected
- Timer function with LCD screen
Cons
- Average protection levels

The APC Wall Outlet Plug Extender is one of the best surge protectors for your investment in a new flagship TV—and space-saving, too. It can generously expand any standard wall outlet into four plugs and add 1,080 joules of surge protection while hardly adding any extra space. That makes it easy to hide behind your entertainment center. It uses your wall outlet’s existing screw hole to fit securely without the danger of coming loose as you unplug your electronics. It also features LED protection indicators to keep you apprised of its current status. Its ability to immediately tell you that the wiring in your home is faulty is especially helpful, as it’ll prompt you to contact an electrician before something goes wrong. Similarly, the ability to set this surge protector’s outlets on a timer to ensure none of your gadgets are on overnight or while you’re not home can help you save energy. At this price point, there’s no better option for super-compact and relatively high surge protection. Because you get six individual outlets, it can also run entertainment devices like streaming boxes or smart speakers.

Power strips, surge protectors, and other power distribution devices are best known for supplementing fixed workspaces and areas of the home. Still, power surges can affect your electronics anywhere and at any time. If you factor in the unfamiliarity of the local power grid and weather, power surges are sometimes more likely to affect your electronics while traveling than at home. For maximum protection of your sensitive devices wherever you go, get the best portable surge protector and enjoy the benefits of surge protection on the road.
Travelers who want extra peace of mind when using power outlets will appreciate the incredibly small form factor and 918-joule protection rating of this USB surge protector from Belkin. It comes in three variants rated for different amperage levels depending on what peripherals you plan on plugging in. It uses a 360-degree rotating plug to maximize its compatibility with strange outlets in hotels, airports, and more. It’s flexible and simple to use, too, with two USB ports offering a combined 2.1 amps of charging power and an onboard protection status LED. It’s great on an RV or travel van because it doesn’t take up much space and won’t overdraw your vehicle’s system. Plus, it’s easy to tote if you want to take it inside a coffee shop or other spot where you may be spending some time.
Best budget: GE 6-Outlet Surge Protector
Simple Yet Effective
Why it made the cut: This ultra-affordable strip is a great option when you need basic protection or you want to keep a spare unit on hand for emergencies.
Specs
- Protection: 800 joules
- Outlets: 6
- USB ports: 0
Pros
- Very cheap
- Compact form factor
- Rotating sockets
Cons
- Limited protection
- No USB
This six-outlet surge protector from GE packs an integrated surge protector and 800 joules of protection into a familiar body, making it one of the best cheap surge protectors for the money. Each of its outlets can be closed with a simple twist for extra safety, and wall outlet mounts on the rear allow users to mount it up and off the floor if needed. It has a three-foot power cord and standard plug and offers incredible value for the money, making it a good choice for shoppers on a budget or users looking to purchase in bulk.
A good surge protector’s key function is preserving your electronics, so it’s hard to compromise on price without a dip in quality. Still, by remaining aware of the joule rating of the surge protector and the wattage of the equipment you’re powering with it, you can accomplish an adequate level of protection at an affordable price point. The GE and similar models are best for stationary use in the home due to less durable casing materials and may not bear the bells and whistles of more expensive units. Still, as long as you’re not powering irreplaceable equipment or operating in a building with a known history of frequent and intense surges, they should do just fine. The GE model strikes the right balance between performance and reliability for basic jobs. You don’t always need maximum protection if you’re just trying to string some holiday lights or have a power strip on hand for emergencies.
What to consider when buying the best 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 and 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. Countless smart plug products on the market allow users to integrate traditional appliances with a smart home system. The best smart surge protectors offer users this same convenient hands-free remote electronics control without sacrificing high-level protection from power surges in a single unit.
Most smart surge protectors offer compatibility with Alexa, Google Home, and other popular smart home systems, but many can function as standalone units. A local Wi-Fi 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 activate coffee makers, slow cookers, and other devices from afar will appreciate the convenience and safety that a smart surge protector provides. These may not be the most robust choice for heavy-duty applications, but they’re 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 devices. 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, 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 to accommodate and ensure there’s room for everything. Otherwise, you’ll be trying to daisy-chain strips together, and that’s not good for anything.
Usage
A surge protector’s job is to keep your electronics safe, but it’s important to consider which gadgets you plan on connecting to it before making your choice. Heavy-duty electronics like computers draw more power than smartphones and will require a surge protector that offers a higher level of protection. Be sure to count the number of electronics you plan on connecting to the surge protector, and get a model that has two or more additional outlets to account for changes you’ll make to your home in the future.
FAQs
A surge protector will cost you between $15-$220, depending on what features you’re looking for.
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. In contrast, 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.
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.
The best surge protectors range 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 and the known reliability of the electrical system you’re using, but when in doubt, the more joules, the better.
Yes. Higher-price surge protectors tend to offer more protection and extras—like integrated USB ports—that less expensive models don’t have. This doesn’t matter if you only plan to use your surge protector with low-powered electronics like smartphones, but it does if you need to plug in a computer.
There’s one significant difference between these two tech accessories: A power strip doesn’t protect the electronics plugged into it during a power surge or other electrical anomaly, while a surge protector does.

Popular Science started writing about technology more than 150 years ago. There was no such thing as “gadget writing” when we published our first issue in 1872, but if there was, our mission to demystify the world of innovation for everyday readers means we would have been all over it. Here in the present, PopSci is fully committed to helping readers navigate the increasingly intimidating array of devices on the market right now.
Our writers and editors have combined decades of experience covering and reviewing consumer electronics. We each have our own obsessive specialties—from high-end audio to video games to cameras and beyond—but when we’re reviewing devices outside of our immediate wheelhouses, we do our best to seek out trustworthy voices and opinions to help guide people to the very best recommendations. We know we don’t know everything, but we’re excited to live through the analysis paralysis that internet shopping can spur so readers don’t have to.
