I am needing to make an inductive charging setup. I see there are several options for transmitters but i am confused to how it all works.

The device i am powering is an arduino with a small 110mah lipo cell. So the circuitry has to switch from charger to battery like a cell phone when it is taken on and off the charging plate. The circuit also has to be super tiny.This coil is similar to the one I am wanting to use.
