Document: Excellent PowerCube Extended USB !!! nice design , well made and work smoothly. it has 2 USB ports with 2x5V output, Provides 4 additional outlets and 1 USB port, Connect multiple Power Cubes together for increased functionality..Great power Cube ..
Excellent design for a power strip. I use it next to my bed and attached it to the night stand. It is a nice small size. They should design one with USB plugs! !
Bought two models, PowerCube Extended and PowerCube Extended USB. Products look good and are very practical. Especially the mount dock is very convenient.Both models have an extension cord. Should have bought one of the Original models so i could stack them and expand to more outlets.
This solved a problem of power needed for several devices in one area.Perfect! If you need your PowerCube to reach a bit further, no worries, because there&#8217;s a special extended edition for that as well.The PowerCube is a smart way to beef up your outlet&#8217;s capabilities simple, affordably and with a nice splash of color.I didn't have to bring all the USB cubes. Everything fits perfectly. It's light stays very cool.
I don't know why some on send negative to this product . Bought two models Power Cube Extended and Power Cube Extended USB, Sturdy. Light weight. I travel with a computer, IPad, Phone, an internet device, and a fan. I can plug everything into this one Power Cube. have mine is on my nightstand and I charge two iPads, an iPhone and still have room to connect a clock and reading light.
This is light weight and really well made. Havent' had any issues whatsoever. Great for keeping in my laptop case! I love it!
The PowerCube is modular and stackable with outlets on five of its six sides. (The sixth side is the plug.) You can build a tower of power outlets, a straight line, or a right angle. You can stick a cube into a wall socket or -- if it has a cord -- conveniently set it nearby on your worktable. You can add another cube when you need it.
Not to mention that it's a good looking power strip with all the different colors
My dog ate the power strip that went in my charger station. This replaced it with tons of room to spare inside! I love it so much.
I bought three PowerCube units together, one of each style. Of the three, two were broken right out of the box. This was not shipping damage, it is poorly designed and cheaply made. Product is not UL listed, but does have a ETL mark.
Answer: yes
