Travel Essential.

Easy to pack; very handy to use anywhere.


Great device

I have been using this at home and it works great. I am really looking forward to using it when I do some international travel later this year. It will solve the problem of the adaptor and also the problem of not finding enough wall outlets.

Helpful Product

Given foreign travel the cube adaptors are very helpful since we have found European hotels don't have a lot of plugs to recharge all your electronics


Very clever, very useful!

An attractive, versatile, compact, clever adapter! What else could one ask for?


Great little adapter

We have an RV that I purchased this adapter for to keep our phones and ipad charged when we travel. We love the small adapter that is so convenient to keep in a small area and love the purple color to locate it immediately when we set up the RV that I purchased a second one for the house!


Very useful...

I found the PowerCube to be extremely useful on my recent overseas trip. Yes, we've used lighter adapters, but none of our other ones have the USB outlet on there and that was a huge bonus on this most recent trip. We had no issues with any of the outlets being able to support it, but it is a little heavy so I could see where some outlets might not hold it.


Wonderful space saver

Once messy space now tamed! I can hardly wait til my European trip and see how the attachments do . .


Perfect travel item

Just went on a trip to Spain and I already had one of the International cubes, but loved how this one worked wanted another. When we got home was the first thing I did was order another. Now I have one for the bedroom and one for the bath when we travel. Perfect!!

The PowerCube Story

PowerCube - Outlet Adapter with USB

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.
