iphone solar charger (again) Answered
Have read through alot of topics but cant find my question answered...
If i use 5v solar panels, with lets say 1000mA power, and simply solder wires from panels to a female usb connector
ex. if i buy a usb extension (male one end /female other end) and cut away the male part and solder the other female part to panels
would this simple circuit charge a iphone ,,or would there have to be other electronic parts involved to make charging happen?
If this does not work , im thinking of buying a car usb socket and solder to 12-15v panels , that should be bombproof as long as you now that the specific socket works with iphone right ?
Downside of that , as i read somewhere on the net is that you loose power when transforming current down from 12 to 5v ?
is that right
ok hope someone has got a answer to me
