A surge protector does two jobs. The visible one is turning a single wall outlet into six or twelve, with USB ports so the phone chargers stop stealing sockets. The invisible one is clamping the voltage spikes that come down the line when a motor kicks in, a transformer fails or lightning hits a mile away, before they reach a TV, a PC or a router. The joule rating tells you how much of that abuse the protector can absorb over its life, and the rest is layout: how many outlets, how far apart they sit, how long the cord is, and whether the strip can be mounted. We ranked the surge protectors in our accessories catalog by joule rating, outlet count and spacing, USB ports, cord length, safety certification and what tens of thousands of owners report.
We have not put these on a surge generator ourselves; the verdicts rest on the published specs and on the owner review history, which for the top picks runs past 100,000 reviews. Prices are not printed because they change daily; every button opens the live Amazon page. If you also need battery backup for a PC or a router, see our UPS battery backups guide, and for strips chosen mainly for their charging ports, power strips with USB ports.
How we picked
- A published joule rating. From 790 joules for lamps and chargers up to 4000 for PCs and home theatre. Strips that did not state one were left out, as was one popular non-surge strip.
- Safety certification. ETL or UL listing and a resettable circuit breaker on every pick.
- Layout that fits real plugs. Widely spaced or three-sided outlets so a wall-wart adapter does not block its neighbours.
- USB ports that are current: at least one USB-C where the strip has USB at all.
- Owner ratings of 4.6 stars or better, and most picks have thousands of reviews.
The picks
ALESTOR 6 Ft Surge Protector Power Strip with 12 Outlets and 4 USB Ports

The ALESTOR 12-outlet strip is the one to put under a desk: twelve AC outlets, two of them two inches apart for chargers and adapters, three USB-A ports and one USB-C for phones and earbuds, a 2700-joule surge rating with a protected light that tells you the circuit is still working, and a six-foot cord that reaches the wall from the back of a desk. It is ETL certified with an overload switch, and almost 20,000 owners rate it 4.8 stars, which is remarkable for a product this cheap. The compromises are small: only two of the outlets have the wide spacing, so plan where the adapters go, and the USB-C port is a 5-volt port for phones, not a Power Delivery port for a laptop. For a home office, a workbench or an entertainment unit, it covers everything at once.
- Twelve outlets and four USB ports on a six-foot cord
- Two wide-spaced outlets for bulky adapters
- Almost 20,000 owners at 4.8 stars
- 2700 joules is plenty for a desk or TV stand
- Only two of the twelve outlets are wide-spaced
- USB-C port is a basic 5V type, not a laptop charger
- Large footprint on a floor
Amazon Basics Surge Protector Power Strip, 6-Outlet, 790 Joules, Circuit Breaker, LED Indicator Light, 6ft Extension Cord, Black

The Amazon Basics 6-outlet strip is the surge protector you buy three of: one for the bedside, one for the kitchen counter, one for the lamp and router in the hallway. It is a plain six-outlet strip with a 15-amp circuit breaker, a six-foot 14-gauge cord and a red LED that confirms the 790-joule surge circuit is still working, and more than 46,000 owners give it 4.8 stars. The honest limit is that 790 joules is a modest rating; it will take the everyday spikes from appliances and motors that wear electronics out, and it is enough for lamps, phone chargers, a modem or a small TV, but a gaming PC or an expensive home theatre deserves the 2700 and 4000-joule strips elsewhere on this page. There are no USB ports and only one outlet is spaced for a transformer plug. As a cheap, certified strip for light loads, it is the default.
- More than 46,000 owners at 4.8 stars
- Six outlets, a 15A breaker and a 14 AWG six-foot cord
- Compact and cheap enough to buy several
- Protected LED shows the surge circuit is live
- 790 joules is for lamps, chargers and small electronics, not a PC
- No USB ports
- Only one transformer-spaced outlet
Wall Charger, Surge Protector, QINLIANF 5 Outlet Extender with 4 USB Ports

The QINLIANF wall tap is the answer to the kitchen counter, the bathroom and the hotel room: it plugs straight into a standard duplex outlet, screws to the centre faceplate screw so it cannot be yanked off, and gives you five AC outlets spread over three sides with 2.1-inch spacing, plus three USB-A ports and one 3-amp USB-C. It is ETL certified with a 1680-joule surge circuit and a protected light, and it is the most-reviewed item on this page by a long way, with more than 118,000 owners averaging 4.7 stars. It only fits traditional duplex outlets, not the rectangular decorator type, there is no cord so it is a wall solution rather than a desk solution, and a heavy power adapter hung from the top outlet will make it lean. For adding sockets where there is no room for a strip, nothing else here is as neat.
- Turns one duplex outlet into five outlets and four USB ports with no cord
- The most-reviewed product here: more than 118,000 owners at 4.7 stars
- Screw secures it so it cannot be pulled off the wall
- 1680 joules in a wall tap
- Fits standard duplex outlets only, not decorator-style
- A heavy adapter on the top can make it sag
- No cord, so everything must sit at the wall
YISHU 6Ft Surge Protector Power Strip with 8 Widely Outlets & 4 USB Ports

The YISHU strip is the three-sided design that solves the wall-wart problem: eight outlets spaced 1.8 inches apart around three faces, so a block adapter in one does not cover the next, plus three USB-A ports and a 3-amp USB-C. A flat 45-degree plug lets the six-foot cord exit downward behind a sofa or a bed, two keyhole slots let you mount it, and the protection list covers surge, overload, short-circuit, over-current, over-voltage and overheating with ETL certification. More than 53,000 owners rate it 4.6 stars. The thing it does not tell you is the joule rating, which the listing omits, so treat it as a light-duty protector for chargers, lamps, a TV and a console rather than a home theatre rack. For a bedside or a dorm room where every plug is a charger, it is the sensible buy.
- Eight wide-spaced outlets on three sides so adapters do not block each other
- Four USB ports including a 3A USB-C
- Flat 45-degree plug fits behind furniture
- More than 53,000 owners at 4.6 stars
- Joule rating is not published on the listing
- Lowest rating of the picks here
- Plastic body feels lighter than the Amazon Basics
Amazon Basics 12-Outlet Surge Protector Power Strip, 4000 Joules, 8ft Extension Cord, Rectangle, for Home, Office, Gaming Room, Black

The Amazon Basics 12-outlet 4000J is the strip for the expensive gear: a gaming PC and its monitors, an AV receiver and a TV, a NAS and a router. Its 4000-joule rating is five times the small Amazon Basics strip and the highest on this page, the housing is flame-retardant polycarbonate with a 15-amp breaker, every outlet has a safety shutter, and the eight-foot cord is the longest here, which matters when the outlet is behind a cabinet. There are no USB ports and the outlets are in a plain rectangle, so plan for block adapters at the ends, and as a newer listing it has about 620 reviews rather than tens of thousands; they average 4.8 stars. If you want surge protection rather than charging convenience, this is the one to buy, and if you want battery backup as well, see our UPS battery backups guide.
- 4000 joules, the highest rating on this page, for PCs and home theatre
- Twelve outlets on an eight-foot cord
- Safety shutters on every outlet
- 4.8 stars from about 620 owners
- No USB ports
- Rectangular layout means adapters block neighbours
- Newer listing with far fewer reviews than the 6-outlet
kasa smart Plug Power Strip KP303, Surge Protector with 3 Individually Controlled Smart Outlets and 2 USB Ports, Works with Alexa & Google Home, No Hub Required , White

The Kasa KP303 is a surge protector you can talk to: three AC outlets that switch independently from the Kasa app, from Alexa or Google Assistant, or on a schedule, plus two always-on USB-A ports for chargers. Plug a lamp, a fan and a TV into it and you can turn each off from the sofa or from another city, set the lamp to come on at dusk, or let away mode toggle them at random while you travel. It is ETL certified for surge protection and connects over 2.4GHz Wi-Fi without a hub. About 16,500 owners rate it 4.6 stars, and reliability of the app and voice control is the most repeated praise. Three outlets is not many, so it is the strip for the living room or bedroom rather than the desk, and it needs a Kasa account. For smart plugs without the strip, see smart plugs for Alexa and Google Home.
- Switch each outlet from the app, by voice or on a schedule
- Works with Alexa and Google without a hub
- ETL-certified surge protection and two USB ports
- About 16,500 owners at 4.6 stars
- Only three AC outlets
- Needs 2.4GHz Wi-Fi and a Kasa account
- USB ports are not smart-controlled
4000J Gaming Surge Protector Power Strip with USB Ports

The 4000J gaming strip is built for the desk with a tower PC, two monitors, a console and a lot of RGB already. Six outlets sit at a ten-degree angle with 1.8-inch spacing so six bulky plugs fit without a fight, the surge rating is 4000 joules with a 15-amp overload cutout, and an EMI/RFI filter cleans line noise that cheap strips pass straight through. There is one USB-A and two USB-C ports at up to 20 watts, and the RGB strip along the edge has four brightness levels and three modes, including off. The six-foot cord has a 60-degree angled plug that sits flat against the wall. It has about 310 reviews, far fewer than the big brands, but they average 4.8 stars, the best on the page, with the 18-month US-based support mentioned approvingly. If you want the joules without the lights, the Amazon Basics 12-outlet above does that.
- 4000 joules plus an EMI/RFI filter for a PC
- Angled, wide-spaced outlets fit six bulky plugs
- Two 20W USB-C ports and RGB that can be dimmed or turned off
- Highest rating here at 4.8 stars
- Only six outlets
- Small review base (about 310)
- RGB and gamer styling are not for every room
HHSOET Rotating 12 Outlet Surge Protector Power Strip, 1200J, 6FT, Black, 1

The HHSOET is the surge protector for the workshop, the garage and the back of a server rack: a twelve-outlet strip in a rugged metal housing with mounting tabs on both ends that rotate through 360 degrees to screw it to a wall, a bench edge or the underside of a desk, then fold away when not needed. It carries a 1200-joule surge circuit, an illuminated on/off switch, a 15-amp rating and a six-foot 14-gauge cord, and it is designed to be bolted down and left alone. About 760 owners rate it 4.6 stars, with power tool benches and under-desk installs the common use. It has no USB ports and the joule rating is mid-range rather than heavy-duty, so it is more about robustness and outlet count than maximum protection; if you have ever cracked a plastic strip with a dropped tool, this is the replacement.
- Metal housing survives a workbench or a garage
- Twelve outlets with rotating mounting tabs for any orientation
- 14 AWG six-foot cord and a 15A rating
- About 760 owners at 4.6 stars
- 1200 joules is mid-range
- No USB ports
- Heavier and more industrial-looking than the plastic strips

How many joules do you need?
The joule rating is the total energy the protector can absorb before its components wear out, so it is both a measure of how big a spike it can take and how long it will last. Under 1000 joules (the Amazon Basics 6-outlet) is fine for lamps, chargers, a modem and a small TV. One to two thousand (the QINLIANF and HHSOET) suits a bedroom or a kitchen with a mix of electronics. Two to three thousand (the ALESTOR) is the sensible floor for a desk with a PC and monitors. Four thousand (the Amazon Basics 12-outlet and the gaming strip) is for a gaming PC, a home theatre or anything you would hate to replace. Whatever the rating, the protected light matters: when it goes out, the surge circuit is spent and the strip is just a power strip.
Strip, wall tap or smart strip?
A corded strip (ALESTOR, Amazon Basics, YISHU, HHSOET, gaming) goes where the devices are and keeps the clutter off the wall. A wall tap like the QINLIANF belongs where there is no room for a strip and everything plugs in at the wall: kitchen counters, bathrooms, hotel rooms, workbenches. A smart strip like the Kasa KP303 trades outlet count for control; it is the right pick for a living room where you want the lamps and the TV on a schedule or on voice, and the wrong pick for a desk full of equipment. If charging is the main point, our power strips with USB ports guide ranks strips on that alone.
Safety and placement
Buy only ETL or UL listed protectors with a resettable breaker, which every pick here has. Never plug one surge protector into another, and never run a space heater, an air conditioner or a laser printer through one; those belong on their own wall outlet. Keep strips off carpet and out from under furniture that blocks airflow, use the keyhole or tab mounts to get them off the floor, and replace any strip whose protected light has gone out or whose cord is warm to the touch. For the few devices that must not lose power, a UPS from our UPS battery backups guide adds a battery to the surge protection.
What is the difference between a power strip and a surge protector?
A power strip only adds outlets. A surge protector adds metal-oxide varistors that clamp voltage spikes, rated in joules, and usually a light that shows the protection is still active. Every pick here is a surge protector; a popular cruise-ship strip in the same catalog is non-surge and was left out for that reason.
How many joules should a surge protector have for a gaming PC?
Aim for 2000 joules or more; the ALESTOR at 2700 is the practical minimum and the Amazon Basics 12-outlet and gaming strip at 4000 are better. The gaming strip also adds an EMI/RFI filter. For true protection against outages, add a UPS.
Do surge protectors wear out?
Yes. Every spike absorbed uses up part of the joule rating, and after a big one the protection can be gone while the outlets still work. Replace the strip when the protected indicator light goes out, and consider replacing any protector older than five years that has lived through storms.
Can I plug a surge protector into another surge protector?
No. Daisy-chaining violates most electrical codes, can overload the first strip, and makes the protection unpredictable. Use one strip with enough outlets, such as the 12-outlet picks here, or a second strip on a different wall outlet.
Will the USB-C port on these strips charge a laptop?
Not usefully. The USB-C ports on the ALESTOR, QINLIANF and YISHU are 5-volt phone ports, and the gaming strip tops out at 20 watts. A laptop needs a 45 to 100-watt Power Delivery charger plugged into one of the AC outlets.
