I don't suppose you can get in touch with the seller to see if there is a mystery box with a wall plug and a matching socket can you? Chances are more than fair that this was paired with a suitable external supply at some point.
I didn't have direct contact as the sale was through a 3rd party seller, but I sent them an e-mail asking if they can check for me. There were a couple of "mystery" parts that I am pretty sure belonged with this.
