That's genius! Put a powerbank with solar panel on the back of an iPhone.
I mean I get that some rich people spend money on expensive watches and similar stuff as status symbol (of their wealth), but that's not the case with this device as it's neither looking good nor actually useful.
Result: Floor broken. (Phone can't be any uglier, so we don't care about that.)
NOT ACTUALLY USEFUL?!?!?! IT CAN SOLARLY CHARGE IN 30 HOURS!!!!!!!! boy, will you be sorry while slowly succumbing to the unbearable sahara heat, unable to tweet for help!
