iFan, charge your iPhone with wind.
Your Smartphone relies on high tech battery power and power management which
you charge almost every day in your outlet in just half an hour.
By using a modified compputer fan it took me 6 hours to charge my
phone, rather long I think… but it works.
I can shave off many charging hours by redesigning the fan blades, making it
more efficient in catching the wind while sun bathing at the beach, doing walking trips
in the mountains or just holding it outside your car window while driving along…
i’ll keep you posted.
