I don't endorse that particular listing, it was just the first one in my search results. It has a QI wireless power receiver, and a right-angled lightning connector. The intended usage is to plug it into an iPhone and put a case on top - but I think it'd work just fine on the bottom of a magic mouse. You could put the power transmitter under the mouse mat and never worry about charging ever again! I haven't tried this so maybe there are practical reasons why it's a bad idea. Has anyone tried it?
