How it works on solar mode?

From solar power it has been set up 4 volts to charge a battery back up of one hour attached to the helmet and a rider can stright away connect the cellular phone unit to the charger for charging while on the move. For a maximum single charging the inventor claimed that the charger takes only 40 minutes compare to the normal charging period which needs for almost one-and-a-half hours.

How it works on wind mode?

At a minimum speed of 20km/hr it's able to produces 4 Volts of electrcity to charge a battery back up of one hour attached to the helmet. It works with the same procedures and methods for charging a cellular phone unit.


On writing this article after I watched news on TV, I don't have any video source to share with readers but this third party's video uploaded on YouTube by "ElektrischerApparat" with the title "Propellerhelmet"  will helps much to explain how the charger mechanism works for charging cellular phone unit.
