This is exactly what was needed!!
Color: White
This is a nice unit. I got it as I have started traveling a bit. It is a headache to try to figure out where to plug everything in to get charges. Especially when you are staying at people's houses, I don't like bothering them. I can put this in my laptop bag and bring it along with all the cords that are still plugged in. I really like that it is two-prong plug and the cord swivels. It will work in any plug-in and location. It costs a bit more than some of the others, but I think it is worth the extra few dollars.

Great
Color: White
Great product. Fits perfectly in my house. Only reason I gave 4⭐️ is because the plug has been loosening out of the outlet and making my tv turn off. The only reason I believe it’s doing that is because of the plug and how it can turn flat. Never had the problem with my tv before using this.

Convenient, Compact, and Powerful – A Must-Have for Any Setup
Size: 5 FT (2 prong plug), Color: White
This power supply is a total game-changer for keeping everything charged and organized. It has a solid number of AC outlets and multiple USB ports (including fast-charging), it is great for charging laptop, phone, tablet, and other gadgets all in one place without a mess of adapters. I use it in my shop to charge pool robots, rechargeable lights batteries for my hand tools and outdoor tools. The USB ports makes it great for charging items that come with a USB cord, no need for an adapter.
The build quality is excellent—sturdy casing, decent cord length, and no overheating even with several devices running at once. I also appreciate the smart layout: the plugs are spaced far enough apart to handle bulky chargers, and the USB ports work reliably.
Great for a home office, bedside setup, or travel. If you’re tired of rotating devices in and out of a wall plug, this is well worth the purchase.
