Idea – Solar Ready USB 18cm In Diameter Fan Setup For Emergency Situations

I think this idea is so good. So I will write it again.

The Solar Ready USB 18cm Fan Setup uses very cheap hardware. 150 SEK for the fan and 100 SEK for the powerbank.

After 4 hours and half hours I turned it off. You probably should not deplete the battery.

Had to recharge the phone during the test.
