Amazing idea - Charge phone by water - DIY Power Bank powered by water-
In this video, I show you how to charge your phone using water.
In fact, in this method, I generate energy from the reaction of metal (aluminum or magnesium) and activated carbon. And because the output voltage is low, we series them together. Then we increase it to 5 volts by the booster module.
In fact, in this method, we make an Aluminum Air Battery, so to reuse, you have to change the aluminum.
Note that the output amperage is low so do not expect fast charging.
