I meant post a photo of the device to be charged, (not the charger).
How does it matter what device needs to be charged until the OP figures out some means to produce a charging current?
It seems to me far more likely that it would be possible to connect to the chargee (!) than that it would be possible to make the chargor (!).
I need to recharge an object (30 cm height) electrically with the water flowing therethrough occasionally. 1 min = 15 litters of water. This object is connected at the smartphone with wifi. I thought of a micro hydro turbine. But I haven't found it yet. Does anyone have an idea?

If you're talking about this why not just take miniature waterfall powered by a dc motor and use it as a generator ?
