None of the equipment in this article does that. It takes power from the grid the way any appliance does; it optionally charges by solar; and it provides power the same way a UPS does, using ordinary female power sockets.
But there are devices out there that do feed power over the exposed prongs of a male plug. They're called "suicide cords" for good reason.
Ah. I saw a whole thing about solar panels for balconies that did exactly this. I skimmed the article and thought I saw the same idea. I missed that it’s just charging a battery.
