A bit bulky but still a terrific product!


good gift item

Exactly what I ordered and expected. It is a gift so it's usefulness will be determined later. I wish it had arrived sooner then it did. There seems to be a conflict with my address which I thought was resolved with my first order, but apparently not which delays deliveries.
Grommet has many interesting things which tempt me to order again, but the long wait on delivery deters me.

More USB ports

I have 4 people all trying to charge their devices at the same time. I need a cube with just charging ports. Do you make that? Also, all those/> Also, all those wires are unsightly, it would be great to have one with short wires that the device could plug right intoMore > < Less


Powe Cube Outlet Adapter

Nice idea to be able to plug several items into one adapter. However, it's heavier than I expected and has a tendency to half slip out of the wall socket. Wish it were not so.More > < Less


Nice, but massive

The powercube works exactly as advertised. I've replaced a couple of USB chargers and still have plenty of outlets. The surprise was just howwas just how big it is. Looking back at the photo and description, I shouldn't be surprised, as the device picture matches perfectly. Usually electronic devices are flimsy and cheaply built. This one isn't. It's heavy, too. Maybe too heavy for my lightweight travel kit.

I may order another with the built in cord.

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.
