Overview

The Southwire 5-Outlet Magnetic Power Strip is what happens when a professional electrical brand decides that plastic strips have no place in a serious workshop. Southwire has spent decades supplying wire and electrical products to contractors and industrial buyers, so this strip carries real credibility. The all-metal body and magnetic mounting system set it apart from the flimsy competitors that tip over the moment a cord gets tugged. Priced squarely in the mid-range, it targets mechanics, makers, and garage enthusiasts who want something built to last rather than something designed to look good on a desk.

Features & Benefits

The housing is cold-rolled steel — not the thin stamped kind that dents if you look at it wrong, but a solid, weighty shell that shrugs off the bumps and drops a busy workbench dishes out. The N35 rare earth magnets deserve attention: at 25 pounds of pull force, that is roughly the weight of a car battery holding this strip locked to your tool chest. Five NEMA 5-15 outlets cover most setups, and one slot is deliberately spaced wider to handle those chunky transformer plugs that always crowd adjacent outlets. The dual USB ports push 2.4A each — solid for phones and tablets, but not a substitute for a dedicated laptop charger. The 8-foot cord gives you genuine reach across a sprawling workbench.

Best For

This magnetic power strip was clearly built for garages, workshops, and job sites — not living rooms. If you work around metal surfaces, the magnetic mounting is genuinely useful; slap it on a tool chest and it holds with authority. Hobbyists running multiple power tools, battery chargers, and a phone all at once will appreciate having five outlets and USB in one fixed spot. Anyone who has watched a plastic strip crack under a falling wrench or slide off a shelf will find the steel construction a satisfying upgrade. That said, the industrial look is a deliberate trade-off — in a home office or beside a TV stand, this metal strip looks out of place, and there are lighter, better-looking options for those environments.

User Feedback

Owners consistently praise the magnet hold — several note it stays put even on vertical metal surfaces where gravity would slide a lesser strip right off. The all-metal feel gets mentioned often as a reason buyers trust it for long-term use. Where people run into friction is outlet spacing: when all five slots are occupied by bulky adapters, the wide-spaced outlet helps but does not fully solve crowding. A handful of reviewers wanted the cord to be longer for larger shop spaces, though most find eight feet workable. USB charging speed satisfies phone users but draws mild criticism from anyone expecting fast-charging. After extended use, durability holds up well — no reports of housing bending or magnets weakening, which is about the best endorsement a workshop tool can earn.

Pros

  • The N35 rare earth magnets hold with 25 pounds of pull force, keeping the strip firmly fixed to tool chests and steel shelving without slipping.
  • Cold-rolled steel construction handles drops, impacts, and heat exposure far better than any plastic strip in the same category.
  • Five outlets cover most workshop power needs, and the wide-spaced slot actually accommodates bulky transformer plugs without blocking adjacent outlets.
  • The 8-foot cord provides meaningful reach across large workbenches without requiring an additional extension cord in most setups.
  • Dual USB ports let you charge two devices simultaneously without sacrificing a single outlet slot.
  • Southwire is a respected name in professional electrical products, which adds a layer of confidence about long-term reliability.
  • At roughly 14.75 inches long, this metal power strip fits neatly on a workbench without dominating the surface.
  • Users report the housing shows no signs of bending or structural wear even after extended heavy use.

Cons

  • The industrial appearance is a genuine mismatch for home offices, living rooms, or any space where visual presentation matters.
  • USB ports top out at 2.4A and do not support fast charging, which is a real gap for users with modern USB-C devices.
  • Five outlets can feel cramped quickly if multiple users are plugging in wide-bodied adapters at the same time.
  • At 2.35 pounds, this metal power strip is noticeably heavier than plastic alternatives, which matters if you move it frequently.
  • Eight feet of cord is sufficient for most setups but restricts placement options in larger commercial or garage spaces.
  • The magnetic mounting is only useful on ferrous metal surfaces — on wood, drywall, or plastic workbenches, it offers no advantage over a standard strip.
  • No surge protection is listed among the features, which may be a dealbreaker for buyers powering sensitive electronics.

Ratings

The ratings below for the Southwire 5-Outlet Magnetic Power Strip were generated by our AI system after analyzing verified buyer reviews from multiple global markets, with spam, bot-submitted, and incentivized feedback actively filtered out. Scores reflect the real distribution of user sentiment — strengths are credited where earned, and recurring pain points are represented just as honestly.

Build Quality
93%
The cold-rolled steel housing earns consistent praise from workshop users who have snapped or cracked multiple plastic strips before. Buyers regularly comment that this strip feels like a professional tool rather than a consumer accessory, and long-term owners report zero signs of structural degradation even in demanding environments.
The steel body adds noticeable weight compared to plastic alternatives, which can be inconvenient for users who reposition their strip frequently. A small number of buyers noted minor surface scratches on the housing arriving out of the box, suggesting packaging could be improved.
Magnetic Hold Strength
91%
The N35 rare earth magnets generate genuine confidence among garage and workshop users — most describe the strip staying locked to tool chest surfaces even when cords are tugged or the chest is rolled across uneven flooring. The 25-pound pull force translates to zero slipping in vertical mounting scenarios, which is where cheaper magnetic products typically fail.
The magnets are only useful on ferrous steel surfaces, which limits placement options significantly. Users who discovered their tool chest lid or shelving was aluminum were caught off guard, suggesting Southwire could do more to set surface-compatibility expectations upfront.
Outlet Layout
74%
26%
Having one wider-spaced outlet thoughtfully built into the design is something buyers notice immediately, especially anyone who has fought with crowded adapter clusters before. For mixed loads involving one or two transformer plugs alongside standard cords, the layout works well in practice.
With five outlets total, the spacing becomes frustrating fast when multiple bulky adapters are in play simultaneously. Several users noted that two large wall-wart adapters placed next to each other still encroach on neighboring slots, making the practical usable count closer to three or four in heavy-adapter scenarios.
USB Charging Performance
62%
38%
For everyday phone charging — Android or iPhone — the dual 2.4A ports handle the job without complaint, and having two USB slots means a phone and tablet can charge at the same time without sacrificing an AC outlet. Workshop users who just need a phone topped up during a long project find this more than adequate.
Buyers expecting fast-charge capability were disappointed, and the lack of USB-C is a growing frustration as more devices move away from USB-A entirely. Anyone hoping to use these ports for a tablet-heavy workflow or newer flagship smartphones will find the charging speed noticeably sluggish compared to modern charging standards.
Cord Length
78%
22%
Eight feet covers the majority of standard workshop and garage workbench setups comfortably, particularly when the strip is mounted on a nearby tool chest and the wall outlet is within reasonable reach. Buyers working in smaller or mid-sized shops describe the cord length as a non-issue.
Users with larger garage layouts or commercial spaces consistently flag the cord as the one area they wish Southwire had extended to ten or twelve feet. A handful of reviewers resorted to using a heavy-duty extension cord, which adds an unwanted connection point in a professional setting.
Ease of Mounting
88%
The magnetic mounting system genuinely removes friction from the setup process — no drilling, no screws, no adhesive residue to deal with later. Workshop users love that they can reposition the strip in seconds when rearranging their bench layout, which rigid-mount options simply cannot match.
Without any alternative mounting method included, buyers who do not have ferrous metal surfaces nearby are left with a strip that just sits on a shelf like any other, negating the premium paid for the magnetic feature. A simple bracket option would make this far more versatile.
Outlet Count
79%
21%
Five outlets comfortably handles the typical workshop load of a power tool, battery charger, task light, and a bench grinder running in rotation. For most hobbyist and light trade scenarios, five is a practical number that does not require a secondary strip.
Power users running a more demanding shop — CNC machines, compressors, multiple chargers — will find five outlets a tight ceiling. The strip does not leave much headroom for growth, and daisy-chaining another strip onto this one is not a recommended practice for safety reasons.
Portability
66%
34%
Despite its steel construction, the strip is compact enough at roughly 14.75 inches to move between locations when needed. Tradespeople who take it to different job sites report it fits easily into a tool bag alongside other gear.
At 2.35 pounds, this metal power strip is noticeably heavier than plastic competitors, which adds up over the course of a long day on the job. Users who move their power setup frequently between workstations describe the weight as a mild but real inconvenience.
Value for Money
72%
28%
For buyers who genuinely need the magnetic mounting and steel durability, the price premium over plastic strips is defensible — this strip should outlast two or three plastic replacements easily. Workshop regulars who factor in the long-term cost see the math working in their favor.
For buyers who do not specifically need magnetic mounting, the price feels steep relative to what the strip actually delivers in raw outlet count and USB performance. The absence of surge protection at this price point is a recurring criticism that undermines the value proposition for some buyers.
Durability Over Time
89%
Long-term owners — some reporting use beyond a year in active workshop environments — consistently note that the housing, magnets, and outlets all perform the same as day one. No reports of outlets loosening, magnets weakening, or the steel body showing stress fractures have surfaced in meaningful volume.
The black finish does show scratches and scuffs over time in rough environments, which matters more to some buyers than others. A couple of users also noted that the USB ports showed signs of contact wear after very frequent plug-and-unplug cycles over many months.
Heat Management
77%
23%
The steel body dissipates heat more effectively than plastic housings, and users running continuous loads over extended workshop sessions report the strip staying comfortably cool to the touch. This is a practical safety advantage in warm garage environments where heat buildup is a real concern.
There is no built-in overload indicator or thermal cutoff mechanism that buyers can observe, so users must rely on the strip to manage thermal stress silently. In extremely hot garage environments during summer, a small number of users noticed the strip running warmer than expected under sustained full load.
Aesthetics & Design
51%
49%
Within the workshop and garage context the strip was designed for, the matte black steel look is appropriate and even has a certain rugged appeal. Tradespeople generally appreciate that it looks like a serious piece of kit rather than a consumer gadget.
In any home or office setting, the industrial appearance is a clear mismatch — it looks out of place beside a desk or in an entertainment console. Buyers who purchased this without seeing it in person first often describe the visual bulk as more aggressive than product photos suggested.
Cable Management
58%
42%
The compact linear layout of outlets makes cord management relatively predictable, and the strip can be mounted close to where cords need to run, reducing slack. Workshop users who plan their layouts carefully find the form factor cooperative.
There are no built-in cord clips, cable ties, or routing channels, so cords simply splay outward in all directions once everything is plugged in. In a busy workshop, this creates a tangle that users must manage entirely on their own.

Suitable for:

The Southwire 5-Outlet Magnetic Power Strip was designed with a specific kind of buyer in mind, and if you fit that profile, it delivers real value. Garage mechanics, woodworkers, and hobbyist makers who work around metal tool chests and steel shelving will find the magnetic mounting genuinely practical — slap it on any ferrous surface and it stays put through vibration, cord pulls, and the general chaos of an active workspace. Tradespeople who need a reliable, no-nonsense power source on a job site will also appreciate the cold-rolled steel housing that does not crack, warp, or break down after rough handling. If you regularly run several power tools, a battery charger, and want to top up a phone at the same time, the five outlets and dual USB ports cover that workload without requiring a second strip. This is a buy-it-once kind of solution for people who have grown tired of replacing cheap plastic strips every couple of years.

Not suitable for:

The Southwire 5-Outlet Magnetic Power Strip has clear limitations that make it the wrong choice for certain buyers, and it is worth being upfront about them. The industrial steel body and black utilitarian finish look perfectly at home in a garage or workshop, but they will look conspicuously out of place in a living room, bedroom, or polished home office where aesthetics actually matter. Anyone expecting fast-charging capability from the USB ports will be disappointed — 2.4A is adequate for phones and small tablets but it is not designed to charge laptops or newer devices that rely on USB-C Power Delivery. Buyers who need more than eight feet of cord reach in a large commercial space may also find the cable length restrictive. Finally, if you do not work around metal surfaces at all, you are paying a meaningful premium for a magnetic feature you will never use, and a lighter, less expensive strip would serve you just as well.

FAQ

The magnets work on ferrous metal surfaces — things like steel tool chests, metal shelving, and steel workbench frames. They will not attach to aluminum, stainless steel, copper, or any non-ferrous metal, so it is worth checking the surface before you buy.

The N35 rare earth magnets are rated for 25 pounds of pull force, which is roughly the weight of a full car battery. In everyday use, a cord tug or light bump will not dislodge it. That said, a hard yank on the cord at an awkward angle could still pull it free, so routing cords cleanly is a good habit.

Not effectively. The USB ports are standard 2.4A outputs, which is fine for smartphones and tablets but well below what modern laptops need. For laptop charging, use one of the five AC outlets with your standard power adapter.

No, surge protection is not listed as a feature of this strip. If you plan to power sensitive electronics like computers or monitors, you may want a separate surge protector in line with this unit or use a different strip altogether.

Eight feet covers most standard workbench setups comfortably, especially when the strip is mounted on a nearby tool chest. For larger commercial spaces where the outlet is far from the work area, you may need a heavy-duty extension cord, though that adds a connection point.

One outlet is intentionally spaced wider to handle one oversized adapter without blocking its neighbors. However, if you have two or three large transformer plugs, you will likely run into spacing issues just like you would on most standard strips. Planning which adapters go where before you buy is a smart move.

No — the magnetic mounting only works on ferrous metal surfaces. Drywall, wood studs, and concrete offer nothing for the magnets to grip. If you need wall mounting in those environments, a different strip with screw-mount brackets would be a better fit.

This strip is not rated for outdoor use or wet conditions. A garage that gets rain intrusion, flooding, or heavy condensation would put the strip at risk. In a dry, enclosed workshop or garage, it handles the typical dust and debris of a working environment well.

The strip weighs 2.35 pounds, and the 25-pound rated pull force handles that weight easily even on a vertical surface like the side of a tool chest. Users regularly report it staying put in vertical orientations without any sagging or slipping.
