Recently i dissassemble an obselete hair trimmer that my dad used and can't find its charger.
i figure out the schematic and found that the wireless charging technology is used
but it seems to have something missing
how the current is limited to 0.1 times the battery capacity?
i uploaded the schematic .

Battery ratings: NI-MH 1.2v 700 mAH

 

I would assume the power of the driving oscillator circuit will limit the current.
