Good Buy - 4 USB Ports (USB C) Hurray! - Fits Well In Cable Management Box - Long Flat (!!!) Cord
Size: 10 Ft, Color: White
Good Product. I have 16 x 6 x 5 cable management boxes. This is the first power strip that I have found with 4 USB ports with USB C. Because it is a single row of outlets, the power supplies for 2 laptops fit in the box. I have those, a lamp, phone, and iPAD, with 1 extra USB and 1 USB C cord plugged in. The low profile inside the larger ventilated box keeps things from overheating. It has taken a bit of adjusting to get everybody in the right place but it works great. The flat cable is smart. It fits under the corner of the rug without leaving a bump.

Great for Any Inside Area
Size: 10 Ft, Color: White
I bought two of these these for my office at work and the power is unstable and there are not many outlets (work for the schools) and the building is old - built in 1977. These have done the trick and I have had no issues with my electronics.

Perfect for my home office!
Size: 10 Ft, Color: Black
This 10 ft power strip has been a game changer for my home office. The cord is super long, which makes it easy to run along the wall or under furniture without any weird stretching. I really like the flat plug—it fits snugly behind my desk and doesn’t take up space like bulky ones do. The 7 outlets are spaced well so I can actually use all of them without the plugs getting in each other’s way. The 4 USB ports (especially the 2 USB-C ones) are super handy for charging my phone, tablet, and earbuds without needing extra adapters. Everything charges quickly, and it feels solid and well-made. I also like knowing it has surge protection built in, especially with how many electronics I have plugged in. Definitely recommend this if you want something that’s sleek, efficient, and built to handle a modern setup.
