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.

Convenient Design but Raises Some Safety Concerns
Size: 5FT, Color: White 2prong, Size: 5FT, Color: White 2prong
As other reviews have mentioned, this power strip does not provide true grounding protection. It allows devices with three-prong plugs to connect through a two-prong wall outlet, but the strip itself still relies on a two-prong connection. Because of that, I think it’s important to understand the potential safety limitations before using it, especially with higher-powered electronics.
It does offer a large number of outlets and USB ports, which is convenient for older homes with limited access to modern plugs. However, considering the price, there are safer and more reliable alternatives available that may be a better long-term choice.

Great little power strip.
Size: 6 Outlets, Style: Desk Socket - White
I used this in my garage as a battery charging station for all my cordless tools. BONUS that is has USB & USB-C that charges my flashlight and phone when I need to plug in! It's super easy to mount.

Perfect just what I was looking for!
Size: 6 Outlets, Style: Desk Socket - Black
This product is great! I bought it to mount under my new desk. It comes with two-sided sticky tape which worked out great. Now all my cords are hidden! perfect.
