When I first saw this, I thought it was a device that you plug into an existing outlet and it contained another outlet for you to plug your appliance into it. It is not. It has wires coming out of it and is designed to control a hard wired device or another outlet. It probably works just fine, but instead of being able to use it it upon receipt as expected (for a non-smart battery charger), I have put it aside to wait for a round toit :-)
