Principle of Water-Electricity.
The water-electricity capsule consists of 2 electrodes, copper (Cu) and zinc (Zn).
When these two metals are immersed in an electrolyte (water), the chemical reaction is converted into electrical energy.
When copper (Cu+) ions and zinc (Zn+) ions are released simultaneously into the water, both metals become negatively charged; however, the amount of Zn+ ions released is much greater that that of Cu+ ions.
This results in an electropotential difference between the Cu and Zn electrodes, which can then function as an energy source generating an electric current.

Note: One refill of the capsules provides continuous energy for about 2 weeks.
For optimum performance, add a little salt to the water.
