Everyone likes the extra outlets and spacing!
Size: 6ft, Color: Yellow
I have a livestream desk shared by a team where we have lots of equipment. We were always running out of outlets and the team had nothing but praise when I installed this 16 outlet replacement. The spacing is perfect for a variety of bricks, plugs and adapters of all sizes. It's metal construction seems very durable and it's easily to mount it solidly to the wall with the wings at each end. The power cord is sufficiently beefy and lighted switch at one end a plus. Overall, we're very happy with its design, capability and value. The extra praise for doing a simple replacement was nice too!

Heavy-Duty Power for Any Workshop or Garage
Size: 6ft, Color: Yellow
I recently upgraded my workspace with the JUNNUJ 16-Outlet Heavy Duty Power Strip, and it has completely transformed how I manage tools and electronics in my garage. Why It Stands Out: Ample Outlets With 16 wide-spaced outlets, it accommodates bulky plugs, adapters, and chargers without blocking neighboring sockets. Perfect for workshops or garages where multiple tools run simultaneously. Durable Construction The full metal housing gives it an industrial-grade feel, and it can handle heavy-duty equipment without bending or warping. Unlike plastic strips, this one feels built to last. Safety First Equipped with surge protection and grounded outlets, it keeps both tools and electronics safe. I feel confident plugging in expensive power tools or charging devices without worrying about power spikes. Practical Length The long cord allows me to reach multiple corners of my garage without needing extension cords, reducing clutter and tripping hazards. Professional-Grade Design Wide-spaced, high-capacity, and metal-built — this is clearly designed for industrial or garage use, not just casual household tasks. It’s heavy-duty without being overcomplicated. Minor Considerations: It’s larger and heavier than standard power strips, so it needs a stable mounting spot or surface. Price is higher than a typical household strip, but for the durability and outlet capacity, it’s worth it. Bottom Line: The JUNNUJ 16-Outlet Heavy Duty Power Strip is a powerhouse for garages, workshops, or any space with multiple high-demand devices. Durable, safe, and highly practical, it’s a must-have for anyone who needs reliable industrial-grade power management.

Works great
Size: 6ft, Color: Silver
Just what I needed for my Dept 56 Christmas display. In past years, it's been a challenge to find enough open plugs for my display. This power strip completely solved that problem. I wish I had found this sooner.

Better than expected - big office cleanup
Size: 6ft, Color: Yellow, Size: 6ft, Color: Yellow
I got this power strip because it seemed like the most plausible one available, notwithstanding the reviews which particularly complained about it being prone to overheating. I certainly didn't want to burn down my home, so I tested it pretty thoroughly before I got anywhere near installing it. The power strip arrived exactly as claimed. It is indeed 45 inches long with sixteen outlets. The power cord is substantial-feeling, and feels like it's probably 14 AWG, or possibly #12 (Pic 1), and was the length I expected (6' in my case). The mounting brackets are sufficient to mount the power strip, but only at the ends, and they can't be concealed. This means that things don't end up as solid as one would like, and if you really care about aesthetics you'll end up being offended, but hey this is a power strip, and if you didn't have it the power cord mess would be way uglier. The outlets themselves are spaced out well enough that there's enough room to put in fairly wide wall wart transformers, but not those which have the plug pins configured such that the transformer has to point sideways. This means that if you want to be able to fill all of the slots, you can only put one of these in, and it has to go at the right-hand end. If you locate it on the left then it covers the switch. In my case, I filled the strip up completely, with one sideways transformer at the right hand end, and I still have many more plugs which won't go, but I've at least managed to improve my cable management a fair bit. Before I installed it, I tested it by boiling an electric kettle using the outlet which is the farthest from the switch (Pic 2). This is the most stressful way to test things, since is stresses all of the wiring and intermediate outlets before it even gets to the one I was using. The kettle draws 11.6 Amps, so about 1400W (though it's amps that actually matter). I then watched the thermal behaviour of the power strip as it worked. As can be seen the first thermograph, Pic 3, the power strip itself stayed cool, indeed barely above ambient. The power meter and power cord going to the kettle are on the right. Pic 4 shows a detail of the switch end of the power strip. The switch never heated to above 77F, which was again barely above ambient. Pic 5 shows a detail of the power meter shown in Pic 2. As can be easily seen, the power cord for the kettle warms up a bit, reaching 100F, but this is clearly the kettle's power cord and plug warming up, not the power strip itself. Pic 6 shows a detail of the unused outlets on the strip. These all warmed up a little, but never got over 83F. To me, this is negligible. As a result of this testing, I had no problems with going ahead and installing the power strip. I knew I'd be filling the power strip, but just adding up the devices I planned to plug in (two desktops, four screens, and numerous other devices), I knew that I wouldn't need more than about 4.5 amps, so I have at least 2.6X headroom. Pic 7 shows a part of the power strip as installed - I couldn't get far enough back to show all of it. Pic 8 is a thermograph of the same, with the power strip running across the middle of the picture. The how spots on the power strip are all transformers - clearly not very efficient, but not actually more than warm, and not the power strip's fault. By contrast, the really hot items visible are a DSL router on the far right, and a VOIP phone device lower on the right. Thus, I conclude that there's nothing untoward with the power strip. Lots of the devices I use are inefficient and/or run fairly hot, but if my house burns down, it doesn't look like it's going to be because of this power strip. All told, this product seems to be very good value for something that actually cleans up my life and has this many outlets. It exceeded my expectations, particularly since my expectations had been lowered by some of the other reviews. It would certainly have been better (for me) had it been longer and with more, and more widely-spaced, outlets, but I can't fault them for making what they made, and their claims seem to have been accurate. Still, the construction is not terribly sturdy and the mounting brackets should have been better thought out.
