Our Picks at a Glance
How To Choose The Best Computer Power Strip
Your computer is the most expensive thing on your desk, and a surge protector is the cheapest insurance you can buy for it. The trick is knowing which specs protect your machine and which ones just pad the box.
Match the joule rating to what you are protecting
A joule is a unit of absorbed energy — think of it as how much of a surge the strip can swallow before it gives up and lets the spike through. A modest strip rated at a few hundred joules is fine for a lamp and a phone charger. A desktop PC, a monitor, and a router deserve a strip rated in the thousands. The higher the joule number, the longer the strip keeps guarding your gear across repeated small surges.
Outlet count is not the same as usable outlets
Six outlets sounds generous until two of them are blocked by a power brick the size of a paperback. Look for a strip with extra space between outlets, or one with angled or rotating sockets, so every slot stays usable once your real plugs are in.
Cord length and plug shape decide where the strip lives
A five-foot cord suits a desk that sits near a wall outlet. If your only socket is across the room or behind a sofa, a longer cord saves you from daisy-chaining strips, which is exactly what you should never do. A flat or angled plug also lets the strip sit flush against the wall instead of sticking out into the room.
USB ports replace your wall chargers
Built-in USB ports let you charge a phone, a watch, or a tablet without sacrificing an AC outlet to a bulky adapter. Check the wattage if you plan to charge a laptop — a low-wattage port will keep a phone topped up but will not keep a laptop alive.

In‑Depth Reviews
1. Amazon Basics Surge Protector Power Strip, 6-Outlet, 790 Joules
Our pick — over 4.5★ from 46,500+ verified ratings; the strongest balance of quality and price.
The plain white workhorse that quietly keeps a computer desk protected for years
If your setup is a tower, a monitor, a router, and a desk lamp, this is the strip that does the job without you ever thinking about it again. It brings 6 outlets including one wider transformer outlet for a bulky adapter, and it runs 790 joules of three-line surge protection — meaning it shields the live, neutral, and ground paths, not just one. The red LED light tells you at a glance that the protection is still active.
What you also get is a 15 amp circuit breaker, which pops and cuts the flow if your desk pulls too much current, plus a 6-foot 14 AWG cord that reaches most wall outlets beside a desk. It is rated 15 amps, 125 volts, 1875 watts, and 60Hz, so it comfortably handles a normal home or office load. At 1 pound it slips behind a desk or into a bag without dragging.
The value case is strong here, and buyers back it up: the review pages are full of people replacing buzzing old strips with this one and calling it sturdier than the price suggests. Two caveats worth knowing. The red protection light is bright enough to be distracting in a dark room, and the recurring fix owners share is simply to mount or turn the strip so the light faces away from you. Stacked against the 12-outlet Amazon Basics pick, this one gives up half the outlets, but the 790-joule rating is the trade you make for a smaller footprint.
What buyers keep coming back for
- Three-line surge protection at 790 joules covers hot, neutral, and ground paths
- 15 amp circuit breaker trips before an overload reaches your PC
- 1 transformer outlet takes a chunky wall adapter without blocking neighbors
- 6-foot 14 AWG cord reaches most desk-adjacent outlets
Where it asks a little patience
- Only 6 outlets, so a full tower plus peripherals fills it fast
- The red LED is bright in a dark room — angle or mount the strip away from you
Buy it for: a normal home or office desk where six outlets covers your equipment.
Step up if: you are stacking a tower, two monitors, and speakers, because the 12-outlet version absorbs that load in one strip.
2. Amazon Basics 12-Outlet Surge Protector Power Strip, 4000 Joules, 8ft
A serious home-office backbone: twelve outlets and a 4000-joule shield in one strip
This is the one to buy when you want the whole desk — tower, two monitors, printer, router, chargers, speakers — on a single protected rail. The headline number is the 4000-joule surge rating, which is a long way above the 790 joules of the 6-outlet Amazon Basics above, so it swallows far more energy before it ever wears out its protection. You also get 12 outlets and an 8-foot cord, so the strip sits where you want it rather than where the wall socket forces it.
Safety details are real, not decoration. A 15 amp circuit breaker trips on overload, PC flame-retardant housing resists heat, and safety shutters close off unused sockets to keep curious fingers and stray debris out. The power on/off switch and back keyhole mount mean you can fix it to a wall stud or desk underside and free up floor space. Rounding it out: 15 amps, and at 1.8 pounds it stays put once positioned.
What wins people over is simply how much it handles and how solidly it does it — behind the reviews sits a pile of desks running a tower and monitors without a hiccup, and the joule headroom is why. If you want the running head-to-head, this strip throws 4000 joules against the 600 joules of the TiFFCOFiO pack below; against the 6-outlet Amazon Basics, it doubles the outlets from 6 to 12 and reaches two feet further with an 8-foot cord versus 6. The one honest knock is the clamping voltage (the level at which the strip clamps down on a spike), which gets mixed feedback — in plain terms, it is a bit higher than some picky buyers expected, so a purist chasing the lowest clamp number may want the Belkin instead.
Best fit: a home office or dorm desk with a tower, multiple monitors, and a rotating cast of chargers that all need one protected home.
The honest trade: at 1.8 pounds it is heavier than the cheap 6-outlet strips and there is no USB charging built in, so phone charging still leans on a separate adapter.
Reach for this if: you want the highest practical outlet count paired with a genuinely high joule rating on one cord.
Consider the Anker 351 instead if: you need built-in USB-C and USB-A ports so your phone and watch never touch a wall charger.
3. TiFFCOFiO Surge Protector Power Strip, 6 Feet, 600 Joules, 2 Packs
Two strips in one box, so the bedroom and the office both get covered at once
Buying a pair solves the problem most people hit halfway through setup: you protect the desk, then realize the bedside table still has a bare wall socket feeding a phone and a lamp. Each strip in this two-pack carries 6 AC outlets with 600 joules of surge protection, uses integrated copper strips for a tighter plug grip, and runs 14 AWG wire to keep heat down under load. The overload switch cuts power the instant something goes wrong.
The housing is ABS + PC fire-resistant material, and the build is ETL and FCC listed, rated 125 volts, 15 amps, and 1875 watts. Each strip runs a 6-foot cord and has four solid mounting holes on the back for screwing to a wall, a desk, or a dorm bed frame. So you are not just buying protection twice, you are buying tidy mounting twice.
Buyers report six months of daily use with no failures. The obvious limitation is the joule figure: 600 joules is the lightest protection in this lineup, well under the 4000 joules on the Amazon Basics 12-outlet. That is fine for a lamp and a charger, but it is not the strip to hang an expensive gaming tower on if you want the longest protection life. Think of the pair as coverage for the low-stakes sockets and the higher-rated strips above for the PC itself.
Why the pair makes sense
- Two 6-outlet strips cover a desk and a second room in one purchase
- Four mounting holes per strip let you screw them to a wall or desk
- 14 AWG cord and fire-resistant ABS + PC housing handle steady loads safely
- ETL and FCC listed with a 125V, 15A, 1875W rating
Where it is deliberately modest
- 600 joules per strip is entry-level protection, not PC-tower territory
- No USB ports, so phone charging still needs its own adapter
Smart pick when: you have two low-demand spots to tidy, like a bedside table and a small desk.
Look past it when: one socket has to shield a full desktop rig, because the higher-joule strips further down carry that load better.
4. CRST 8 Outlet Metal Heavy Duty Power Strip, 15A/1875W
An aluminum-bodied strip for the bench where plastic strips go to die
When the strip lives next to a drill press or under a workbench, the housing is the spec that matters most, and this one is 1.5mm extra-thick aluminum alloy with reinforced engineering plastic covers. That metal build is why the strip survives knocks and drops a plastic one would not. It packs 8 outlets rated 15 amps and 1875 watts through 14 AWG SJT-grade 6-foot wire, backed by 2100 joules of surge protection and a 15 amp circuit breaker for overloads and spikes.
Two design details separate it from a generic strip. The outlets sit 1.7 inches center-to-center, which means bulky power bricks and tool chargers sit side by side without fighting for the same socket. And the strip is sized to fit standard 16-inch stud spacing, so it nails straight onto wall studs, with 45° angled flat plug and hanging slots rounding out the mounting options.
The review pages treat this as the grown-up option next to no-name strips — the phrase that keeps surfacing is how firm the outlet grip feels and how high-draw tools run without voltage sag or tripping. The one want that keeps appearing is a bump to a 20 amp rating for even hungrier loads, so if your tools pull near the 15 amp line, know that is the ceiling. It also ships with an 18-month warranty. Against the plastic-bodied strips above, it is the tougher shell — the trade is a heavier strip that is meant to be bolted in place, not tossed in a drawer.
Shop-grade honesty: the all-metal body is the reason this one earns a bench spot — it takes the abuse a light plastic strip will not.
The ceiling to respect: 15 amps is the limit, so a workshop pulling near that number day after day is where the strip stops and a dedicated circuit starts.
For the garage and workshop: mount it on the stud, load it with chargers and tools, and forget it.
Not the one for a tidy home office: the metal weight and industrial look suit a bench, while a lighter strip sits better under a desk.
5. Anker Power Strip with 2100J Surge Protector, 12 AC, 1 USB-C, 2 USB-A
Twelve outlets plus a fast USB-C port that clears the charger clutter off your desk
This is the strip for the desk where every device seems to arrive with its own wall brick. It gives you 12 AC outlets, 1 USB-C port, and 2 USB-A ports in one unit, so a phone, a watch, and a tablet can charge without borrowing a single AC slot. The USB-C port delivers 20W, enough to take an iPhone 15 from 0 to 50 percent in about 26 minutes, while the three USB ports share a 15W maximum.
Spacing is the quiet win — the outlets are laid out with extra room so bulky adapters sit side by side instead of blocking each other, which is the exact complaint that ruins a cheap strip. Surge protection runs to 2100 joules behind an 8-point safety system covering surge, fire resistance, overload, and temperature control. The 5-foot cord is sized for desks around 4 to 5 feet wide, and it also suits a bedside or sofa-side table. It comes TUV listed, and at 1.3 pounds it is easy to reposition.
What the reviews celebrate is the flat, modern shape and the spacing that finally fits real-world bricks — as owners put it, the wide outlet spacing “easily fits bulky power bricks side by side without blocking adjacent plugs.” The honest wrinkle is the USB ports: some owners mention the USB-A ports eventually stop working, which is worth knowing if USB charging is your main reason for buying. If you would rather have more AC outlets and skip the smart charging entirely, the Amazon Basics 12-outlet delivers 4000 joules versus the 2100 here, so it wins on raw protection while this one wins on convenience.
Why it earns the desk spot: 12 spaced outlets plus 20W USB-C means one strip replaces a pile of adapters without a single plug fighting another.
What to weigh: the USB ports are the one soft spot in an otherwise stout strip — lean on the AC outlets first and treat the USB charging as a bonus.
Built for: a desk that juggles many devices and wants fast phone charging without extra adapters.
Go elsewhere if: maximum surge protection is the whole point and you would rather trade USB convenience for the higher 4000-joule rating.
6. NANOLAKE 18-Outlet Surge Protector, 4800J, 10ft Cord, USB A+C
Eighteen outlets and a ten-foot reach for the desk that officially ran out of sockets
When your setup has outgrown the idea of “enough outlets,” this is the strip that ends the unplugging ritual for good. It carries 18 wide-spaced AC outlets plus 4 smart USB ports — 2 USB-A and 2 USB-C with 20W PD — so a laptop, monitor, console, phone, and tablet all stay powered without a single blocked plug. The 4800-joule surge rating is one of the highest here, sitting just below the SUPERDANNY’s 5000 joules and above the Belkin’s 4320.
The cord is the other headline: 10 feet of reach with a flat plug, so it stretches from a desk across the room to a wall outlet that used to be out of bounds. Grounded and protected LED indicators light up so you can see at a glance whether your gear is shielded. The build is reinforced ABS housing with a thickened cord sheath and rock-solid sockets, rated 15 amps, and the strip weighs 1.6 pounds. It mounts three ways — side, top, or back — to fit tight spaces behind furniture.
The reviews keep landing on the same two things: a clean, space-saving design that saves plugs, and a short power outage that the strip rode out without leaving any electrical gremlins behind afterward. If outlet count is your bottleneck, nothing here touches it — 18 outlets against 12 on the Belkin and Amazon Basics, or 13 on the SUPERDANNY. The trade for all that capacity is a longer, bulkier unit, so measure your space before you commit; it is happiest behind a desk or under a shelf where all those sockets can actually breathe.
what separates it
- 18 wide-spaced AC outlets plus 4 USB ports at 20W PD cover the biggest desks
- 4800 joules of surge protection with grounded and protected LED indicators
- 10-foot cord with a flat plug reaches outlets other strips cannot
- Three-way mounting (side, top, back) tames tight spots
What to plan around
- It is a long, substantial strip, so it needs a real shelf or desk edge to live on
- All that capacity can tempt you to overload a single circuit — stay within the 15 amp rating
The answer for: a full home office, gaming rig, or studio that has genuinely run out of outlets.
Overkill for: a simple two-device desk where a smaller strip would do the same job with less bulk.
7. SUPERDANNY Power Strip Surge Protector 5000J, 6.5FT, 13 AC
The top of the joule ladder — 5000 of them guarding a PC tower and workbench at once
If the number you care about is raw protection, this is the ceiling of the lineup: 5000 joules, the highest here and above the NANOLAKE’s 4800, the Belkin’s 4320, and the Amazon Basics 12-outlet’s 4000. Industrial-grade surge protection on that scale is aimed at equipment you genuinely cannot afford to lose — a tower, a home theater receiver, or a workbench of gear. LED indicators show whether your devices are currently shielded.
It backs that up with 13 widely spaced outlets and 4 fast-charging USB ports, including 2 USB-C and 2 USB-A, that run both PD (Power Delivery) and QC (Quick Charge) protocols at 20W max — so your phone and tablet top up without stealing an AC slot. The build is fire-retardant casing with 8-fold protection covering overload, short-circuit, overheat, over-voltage, over-current, surges, ground faults, and open flames, and the strip is rated 15 amps and 1875 watts. A 45° flat plug clears tight spaces behind furniture while leaving the lower outlet usable, and screws plus a drill template are included for wall mounting.
Owners point to the outlet count and spacing as the reason it works for a computer and a TV home theater in one spot — the brick-plug spacing is the detail that keeps the whole rail usable. One physical quirk shows up in the reviews: the outlets are stiff at first, and plugs need a firm push before they seat. It is a snugness rather than a fault, but worth knowing so you are not surprised. The piece to weigh is the 6.5-foot cord — shorter than the NANOLAKE’s 10 feet and the Belkin’s 8 — so if your only outlet sits far from the setup, that reach is the deciding factor.
The strongest points
- 5000 joules is the highest surge rating in this lineup
- 13 spaced outlets plus 4 USB ports (2 USB-C, 2 USB-A) at 20W max
- 8-fold safety protection with a 45° flat plug and included mount screws
- Handles PD and QC fast-charging so phones and tablets charge without an adapter
Small things to note
- Outlets are stiff when new — expect a firm push to seat each plug
- 6.5-foot cord is shorter than the 10-foot NANOLAKE, so plan your outlet distance
Match this to: a high-value PC or home theater where the maximum joule rating is the whole reason you are buying.
Pick the NANOLAKE over it if: your setup sits far from the wall and the extra cord reach wins out over the surge number.
8. Belkin Surge Protector Power Strip, 8 Rotating & 4 Standard Outlets, 4320 Joules
Eight outlets that physically swivel, so the weird-shaped brick finally stops hogging the rail
The problem this strip solves is the one every packed desk knows: a wall wart the size of a deck of cards arrives and blocks two sockets while using one. Belkin’s answer is 12 AC outlets split into 8 rotating and 4 standard, so the swiveling ones pivot out of the way and let large or direction-sensitive plugs share the space. It pairs that with 4320 joules of surge protection, high enough to sit comfortably in this lineup’s upper tier, plus phone-line and coaxial cable protection for a cable box or satellite box.
The safety story is layered — an 8-point system covering over temperature, overcurrent, overload, short circuit, and clamping, plus 3-line AC protection across hot, neutral, and ground, LED indicators for surge and ground, and fire-resistant material. The 8-foot cord uses a 3-prong angle plug that tucks into tight spaces. The unit carries UL certification, a 2-year warranty, and a connected equipment warranty, and at 2.5 pounds it is the heaviest strip here.
The thing everyone raves about is the pivoting design — turning sockets and arranging them so that odd plugs finally cooperate is what turns a jumble of cables into something organized, and it is the reason this strip keeps showing up under desks and behind AV racks. The recurring snag is small: the rotating outlets can be stiff to turn, especially when new. Set against the 12-outlet Amazon Basics, the Belkin costs more protection when it counts — a jump to 4320 joules from the Amazon Basics’ 4000 is modest, but the swiveling sockets and the UL certification (a safety standard from Underwriters Laboratories) are the real upgrade, plus the coaxial and phone-line protection the plain strips do not offer.
Where it earns its keep: pivoting outlets plus 12 sockets mean bulky and angled plugs all find a home, and the coax and phone-line protection guards the cable box too.
What to factor in: it is the heaviest strip here at 2.5 pounds, and the swivel sockets need a firm turn — neither is a problem unless you wanted something featherweight for a bag.
The pick for: a desk or home theater jammed with mismatched, oversized, or awkwardly angled adapters.
skip it if: you want the lightest possible strip to toss in a laptop bag, since this one is built to stay put.
9. Anker Nano Power Strip, Desk Clamp, 70W Max, 1500J Surge Protector
A power strip that clamps to the desk edge and charges a laptop from its own USB-C
This is the one for a standing desk, where trailing cords and a strip on the floor are the enemy. It clamps straight onto the desk edge so the ports ride with the surface as the desk rises and falls, and it splits its 10 ports into top and bottom zones — 6 AC outlets, 2 USB-C, and 2 USB-A — to keep the working surface clear. The headline port is the USB-C rated for up to 70W using GaN (gallium nitride, a material that lets chargers run cooler and smaller) technology, enough to run a laptop, a tablet, or a phone from the strip itself.
The clamp is the engineering trick: it is adjustable, holds secure, and lets you plug or unplug with one hand without the strip sliding around. It fits desk edges from 0.6 to 1.8 inches thick. Do know its limits — it is not designed for curved edges, edges sloped beyond 45°, or desks with no edge to clamp to, so a glass or beveled desk may not work. Surge protection is 1500 joules, and the 5-foot cord suits a desk-sized setup, and at 1.4 pounds the whole unit stays light enough not to stress the edge.
What makes owners fans is how the clamp saves the desk surface and how the ports are arranged — including one standing-desk setup that runs a docking station, two monitors, and the desk itself off this single strip. One quirk to know: the USB ports are not created equal. The left USB-C carries the strongest charge, while the right USB-C and the two USB-A ports deliver more modest wattage, so a power-hungry device may not be happy on every port. If that USB layout matters less to you and you just want AC outlets at a low profile, the Amazon Basics 6-outlet above is the simpler spend.
Why the clamp wins: ports that travel with the desk mean no more chasing a strip that slid off the back, and 6 AC outlets plus 4 USB ports keep the surface clear.
The port caveat: only the left USB-C runs at full strength, so route your heaviest device there and treat the other USB ports as lighter-duty.
Made for: a standing desk or a sleek setup where the strip must live on the edge, not the floor.
Think twice if: your desk edge is curved, sloped, or missing entirely, because the clamp needs a straight edge to bite.
Understanding the Specs
Joule Rating
A joule is a unit of energy, and on a surge protector it measures how much of a spike the strip can absorb before its protection is used up. Think of it like a sponge that soaks up sudden voltage, and once the sponge is full it cannot soak any more. A higher number buys you a longer protection life across repeated small surges, which is why strips protecting a computer tower typically aim into the thousands while a strip for a lamp can sit in the hundreds.
Circuit Breaker and Amperage
A circuit breaker is a built-in switch that trips and cuts power when the strip draws more than it is rated for, protecting you from an overload. The rating to watch is amperage, and a 15 amp strip running at 125 volts equals 1875 watts of capacity, which covers a normal computer and peripheral load. If you keep piling devices on, the breaker tripping is the strip telling you it has hit its ceiling, not a fault.
Outlet Spacing and Plug Type
Outlet count means little if a single bulky adapter blocks its neighbors — that is why spacing, often measured center-to-center between sockets, decides how many plugs you can actually use. Rotating or angled outlets go further by letting odd-shaped plugs turn out of the way. A flat or angled plug on the strip itself lets it sit flush against the wall instead of jutting into the room.
Cord Length and Wire Gauge
Cord length decides where the strip can live, but a longer cord is no use if the wire is too thin for the load. Wire gauge runs in reverse — a lower number means thicker wire that carries current with less heat, so 14 AWG handles a full load more comfortably than thinner wire. Pair a cord long enough to reach your outlet with a gauge heavy enough for everything you plan to plug in.

Final Thoughts: The Verdict
For the majority of shoppers, the computer power strip winner is the Amazon Basics 6-Outlet, 790 Joules because it pairs three-line surge protection and a 15 amp circuit breaker with a price that makes protecting a simple desk an easy yes. If you want to run a whole workstation with room to spare, grab the Amazon Basics 12-Outlet, 4000 Joules for its doubled outlet count and far higher surge headroom. And for the desk that has genuinely run out of sockets, the NANOLAKE 18-Outlet, 4800J is the one to reach for — its 18 spaced outlets and 10-foot cord mean you can stop unplugging one device to charge another,
