A:Answer I’m not exactly sure which item you’re referring to but.... the hub itself only plugs into the item you hook it up to. For instance, I use it with a laptop. I only have to plug it into a USB port on the laptop for it to work (there is no power cord to the hub which is why I like it, less cords). Now if you mean plugging in the item you hook it up to..., basically the hub will have power as long as the item does. As long as my laptop has battery life, I don’t have to plug in my laptop for the hub to work. Hope this answers your question.
