Amazon saves the day!!!!! Again.....
Size: 4 Pack, Color: A-Ivory White
These adapters are AMAZING!!! I live in an old home and all the wall plugs are two prong. But it seems these days everything is three prong. I had no idea until I saw these on Amazon, three prong adapters even existed!!! Amazon, once again, you've saved me lots of frustration and made my life so much easier. Thank you!!!! Very sturdy. Well made. Excellent price for 4!!!!!

saved me in a house full of old outlets
Size: 4 Pack, Color: A-Ivory White
My landlord's house is really old and basically every single outlet is two prong which was an absolute nightmare for all my stuff. These little adapters just plug right in and suddenly everything works no problem, and getting 4 of them for under 10 bucks is a genuinely great deal. They feel sturdy enough that I don't worry about them coming loose and they don't stick out too far from the wall either.

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.
