  2. 7-12V on Vin pin

I believe you are trying to duplicate the QI charging system used in cell phones. Unfortunately it is not as simple as just getting a coil and a battery.

The wireless system provides AC voltage and current at the receiving coil. This must be rectified and made to charge a battery. I don't know about the phone chargers but my toothbrush runs at 20kHZ.

You will need:

  1. Receiving coil
  2. circuit to convert to DC voltage
  3. circuit to regulate the voltage from 2)
  4. battery or load.

The voltage from the receiving coil will vary a lot. THis is due to variations in coupling from the source coil.

To continue, you might want to find a wireless cellphone charging adapter. I've seen them as replacements for the back of some older phones.

Or you could look at things like this ZENS Qi-enabled portable battery makes charging truly wireless, almost

good luck
