Novel idea ,but the 10 FT cord is a mess, not necessary and the gauge of the cord is toooo stiff to work with, I'm sorry I opted for the 10 10 cord a 5/6 would have been preferred with a lighter gauge of wire,More > < Less


Great idea but disappointed it isn't travel friendly

Love the idea of this cube! I thought it would be great for travel and it is, within the US but not abroad which is a big disappointment. I should have read the description more closely as I probably wouldn't have bought this had I known I couldn't use it abroad. Foreign hotels often have limited outlets so I usually travel with a power strip. I liked the idea of this because it would take less room in a suitcase. Please make these rated for 125/220 so they are travel friendly.
It'll still be fine for domestic travel and using around the house which is what I'll use it for.

PowerCube with extension cord

Not what I expected. Big, bulky, heavy - not conducive for travel which is why I purchased it. Really disappointing considering the price. I'm going back to my trusty extension cord! Pass on this one.More > < Less

Loved it until the USB ports failed!! Both at the same time!!! Having it less than two months is beyond disappointing!!!

The cube is heavy and doesn't stick to the surface. Waste of money.

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.
