solar charhers are just mny idea to help African Steemit users like @ortigas100 who go through places without any electricity and simply need a few extra hjours of charge to get online...they culd stay connected with people from around the world in the niddle of african countyr side...and all they need is a $9 solar charger?!?! To me Its such a simple fix! we should just flood africa with these devices so everyone buys one WITh their smartophone! we should make it so smartphones COME WITH these solar batery chargers!
