One of the major benefits of using one of the two models of Raspberry Pi Zero, including the new wireless model, is the lack of power consumption.

Power strip are a large, awkward, and difficult if you need to use your gadgets while you charge them. The PowerCube ditches the bulk, and gives you plenty of outlets in a compact package, making it easy to plug in your devices while you use them around the house.
