Cube plug

Like the simplicity of it and the fact that it is a 3 in one, ext cord, electric plug and USB port.
Stickies don't stick
05/07/2019 by Nancy
I was excited to get the PowerCube because the last thing I want to do is crawl under my desk at work to plug things in. There are two issues. First, the sticky pads that come with the cube don't stick well enough and the cube falls off the underside of the table. Nails appear to be an option, but the cube did not come with any. Second, once you attach the cube to the white flat holder, it pivots - it doesn't lock in place. Good idea, with better parts needed.

This is my 3rd cube extension. They are really handy and don’t take up a lot of space. I like the USB ports most of all.
Works fine, size/shape awkward

It seems designed for attaching to the underside of a desk or table. Could be perfect for that. The cord is stiff and short and the cube large, so it doesn’t fit well into an environment where it can’t be tucked away. Plugging the USB cords in is fine, but pulling them out is way too hard, so that side of the cube isn’t useful to me; if I find a table to stash the cube under, I will use the USB side to attach to the provided Velcro strips. I do use it and like having several grounded plugs to use without a foot-long power strip, but it isn’t as unobtrusive as I had hoped.

USB Outlet Adapter + 5 ft. Extension

This modern power socket includes two USB ports as well as four outlets. With the cube shape, there’s no worrying about fitting larger adapters next to one another. With the 5 foot extension cable and easy mounting dock, you can mount it under your desk or elsewhere for more convenience.


PowerCube is a modern reinvention of the traditional power strip. It offers more functionality—like two added USB ports—and is made to look better, too.

Charge your smartphone, tablet and more with this USB outlet adapter that also offers four traditional power outlets. The clever cube shape erases the problem of having two plugs that are too big to fit next to each other. On PowerCube, you can use every single outlet. You can even stack PowerCubes to get more outlets as needed.

PowerCube looks better than power strips or extension cords, and it’s far easier to keep within reach. With optional mounting accessories, it can be put on a desk, under a table—wherever you need power. No more crawling behind furniture to reach outlets.

Plugging in and charging up is now convenient for our tech-happy world. more Their Story
