Technically, it’s still wireless, but you obviously can’t use it as a traditional wireless charger. In terms of convenience it’s more like a wired charger, or compact powerbank. Maybe even worse, because every time you plug it in, you are bound to start questioning your life choices.
Still, if you like pointless gadgets, and you’re not an Apple fan (these categories may or may not be mutually exclusive), you can get the Duracell Powermat for $54. We just don’t see why anyone should.
