I have been crawling under my desk at work everytime I need to plug something in. Of course they put the outlet way under the fathest point of the L shaped desk. Then the Grommet to the rescue. As a senior still in the workforce, I am always trying to find things to make my job easier. I often find I need to adapt things I've done for years to accommodate my new achy joints and limitations. Thanks you Grommet, the PowerCube was the perfect solution.More > < Less


Great Product!

I love my power cube. In my craft room I have so many appliances, some of which I use only occasionally. Having to crawl under my work table to unplug and plug in cords was inconvenient. Now with the cube attached under the edge of my table it's easy to plug and unplug those infrequently used appliances. Only one problem, the double back tape that is included in the package does not hold as well as I'd like. I had to replace it with somethings else.More > < Less

PowerCube - Outlet Adapter with USB

About PowerCube

Reachable Power

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.
