Good value for a high quality product with some possible safety compromises
Size: 5FT, Color: White 2prong, Size: 5FT, Color: White 2prong
This power strip is a practical solution for anyone living in an older home that still has two‑prong outlets. Many older houses were built long before grounded wiring became standard, so finding a way to expand your available outlets without rewiring the entire room can be a challenge. This adapter is designed specifically for those situations, and it provides a surprising amount of capability in a compact unit.
Before using it, I wanted to be sure it was safe to plug a three‑prong device into a two‑prong outlet. It is legal to use an adapter like this in the United States, but only when you understand its limitations. A two‑to‑three‑prong adapter does not create a true ground. The product page notes that this model is built to UL 1363 standards and includes surge and overload protection, which helps add a layer of safety for older outlets. Still, it is not a substitute for proper grounding, and anyone who wants full protection should eventually have an electrician install grounded outlets.
As for the device itself, it is well designed and easy to use. The main body includes 11 outlets, along with 3 USB ports and 3 USB‑C ports for charging phones, tablets, and other small electronics. All USB ports are standard 5V. There is a power switch with a green indicator light, and the back of the unit includes mounting holes if you want to secure it to a wall or desk. The size is compact—about 8 inches long, 4 inches wide, and just over an inch thick—so it fits neatly in tight spaces.
Overall, this is a good value for anyone who needs more outlets and charging options in a home with older two‑prong receptacles. It offers convenience, versatility, and thoughtful safety features in one organized unit.

Great many outlets but insufficient usb power for most needs
Size: 5FT, Color: White 2prong, Size: 5FT, Color: White 2prong
I absolutely LOVE how many ports/outlets this extension unit has. It has usb-As, usb-Cs, AC outlets, on/off switch... In that regard, it's perfect.
But. If you're looking to charge your phone or laptop, for example, by plugging your charging cord without an adapter, directly into a usb-c or usb-a port, you'll be completely out of luck. When I first got this I plugged in my laptop cord directly into one the usb-c ports while using it. I eventually, fairly quickly I must say, realized that it was as though the laptop wasn't plugged in at all. It even seemed to lose power faster than if it weren't plugged in! And, it was the only thing plugged in at the time. So it might just be me expecting a charge instead of the opposite, but the issue stands. I had to go and find my A/C adapter and charge my laptop the same way I would without this unit, as if I was plugged into the wall.
Now I'm sure there are people out here surprised that anyone would be confused by having to use an adapter to charge a phone or laptop while using this unit. My confusion comes from the unit having as many usb-c and usb-a ports as it does. I don't think it's a stretch to assume, as I did, that the point of having so many ports is to actually use them. One reason I haven't rated this lower is that I knew of the ports low voltage and wattage, so I wasn't completely surprised by having to use an adapter, though I WAS surprised by how completely useless the usb ports seem to be. Also, one description picture shows a phone being charged WITHOUT an adapter. And this does charge my phone but only if I'm not using it. It stays at pretty much the same battery level if I'm using it while charging it. So I don't think I'm 100% at fault for being surprised
If you will be using the usb ports to charge a small appliance, a groomer, a shaver, a toothbrush? I'm sure this will do well. I don't have any of those so I guess I won't be using the usb ports at all or will use them only if I'm not in a rush to get a fast charge.
Once the initial surprise subsided, I'm still glad I got this. It has ELEVEN A/C outlets, a flat plug that can fit just about anywhere and behind any piece of furniture, and I could still charge my phone (thought not my laptop) in a pinch. I think the price at the time of this review is fine for those features. 3.5 stars.

Many Outlets in One Compact Device!
Size: 5FT, Color: White 2prong
The number of outlets is impressive for its size, and the USB ports are super convenient for phones, tablets, and other small devices. Everything charges steadily without overheating, and the 5 ft cord gives enough flexibility to place it where I need it. I also really appreciate the compact design. Even with so many plugs available, it doesn’t feel bulky or cluttered. It fits nicely behind furniture and keeps everything organized instead of having a mess of adapters everywhere. It’s especially perfect for older homes or apartments with only a couple of outlets per room. While it’s not a substitute for true grounded outlets for heavy appliances, it works perfectly for everyday electronics.
These items are typically fine:
Phone chargers
Laptops
LED lamps
Routers / modems
TVs (modern, low draw)
These devices are double-insulated or low risk, so they don’t rely heavily on grounding.
Avoid using this for:
Space heaters
Air conditioners
Microwaves
Refrigerators
Power tools
Anything metal-bodied or high-power
Without a real ground, a fault could energize the casing and increase shock risk.
Overall, this is a solid, reliable, and incredibly convenient power strip. I’d definitely recommend it to anyone needing more outlets and USB charging in one simple solution for appliances motioned above that are safer to use with relatively better price.

Perfect Sofa-Side Charging Hub
Size: 5FT, Color: White 2prong, Size: 5FT, Color: White 2prong
I picked this power strip mainly to use next to my sofa, where I usually charge my tablet, phone, and laptop while relaxing in the evening. Having 11 AC outlets and multiple USB ports in one place has made that corner much more organized, and I no longer have chargers scattered everywhere.
The layout is well thought out. Larger plugs don't block neighboring outlets, and the flat angled plug fits nicely behind furniture. The 5-foot cord gives enough flexibility to position the strip where it's most convenient. I also like having both USB-A and USB-C ports available for smaller devices. For phones, tablets, earbuds, and similar electronics, the built-in USB ports have been very useful.
For my everyday use, charging personal devices and powering small electronics, the unit has performed as expected. The overload protection switch and built-in safety features provide additional peace of mind.
Overall, this has been a practical solution for adding more outlets to an older two-prong receptacle while keeping my charging area tidy and easy to access.

Major Safety Red Flag! 3 Prong Outlets, 2 Prong Plug, This Does Not Provide A Grounded Connection!
Size: 5FT, Color: White 2prong, Size: 5FT, Color: White 2prong
This power strip has a compact design, a convenient outlet layout, and USB ports, so on the surface it looks useful. The patented three-row layout is clever for spacing the outlets, but that only applies to how the outlets are positioned. It does not change how the strip is actually powered or protected.
The problem is the safety design. It has 11 three-prong outlets, but the wall plug itself is only two-prong. Without a ground prong, it is not grounded. The two flat prongs are hot and neutral only, so this does not provide the grounded protection that the three-prong outlets appear to suggest.
That also makes the surge protection claims highly questionable to me. A real grounded surge protector should have a grounding path for excess surge energy. With only a two-prong plug, I would not trust this to provide the kind of surge protection people generally expect when plugging in electronics or grounded devices.
The manual mentions surge protection, ground protection, short-circuit protection, over-current protection, over-voltage protection, over-heat protection, and UL 1363 safety standards, but I could not find any visible UL, ETL, or similar safety certification mark on the unit or paperwork. The only marking I saw was FCC, which is not the same thing as electrical safety certification. Given the two-prong plug and three-prong outlets, those protection claims feel dubious at best and misleading at worst.
The USB charging is also underwhelming. The total USB output is listed as 24W, which is not much for today’s devices, especially when that power is shared across multiple ports. We frequently use 35W or higher from a single USB charger, so I would not buy this for fast or modern device charging either.
Because of the two-prong plug paired with three-prong outlets, I will absolutely not use this. I do not want a power strip that makes devices appear protected or grounded when they are not. For me, this is not a small design issue. It is a serious safety concern.
