How does it work?
As we mentioned just before, the Wildcharger Pad and Adapter uses a form of direct contact conduction. Although they use magnetic contacts on the back of the adapter, these are nothing more than an extra step to ensure good contact between the pad and adapter.
According to WildCharge, they use an "ancient Chinese secret" to allow the pad to know when an adapter has been placed on it. Although I was not able to get more information from them, I am sure this is some form of RFID device that identifies the adapter to the pad and completes the circuit for charging. This also allows the pad to know when a foreign object is placed on it and to deactivate itself to prevent damage to the pad, foreign object, or any adapters on the pad.
Once the circuit is complete, the charging begins. As we mentioned above, this is direct contact conductive charging and as such there is very little energy that is lost (unlike many inductive charging systems). As such, it should use a little less power from the wall to charge your devices.
If you are not familiar with direct contact conductive circuits, let me give you a very simple example of one you use every day. When you plug in your cell phone to the wall charger you are creating a conductive circuit. This circuit runs to pads in the battery compartment of your phone. These pads make direct contact with the battery and transfer the charge from the wall to the battery (through the charging hardware in the phone of course).
