I have a solar panel that emits 5 volts, and I would like to try to charge my iPhone with it. Should I connect the I/O wires directly behind the lightning plug, or is the big transformer block important?

I guess the block is used to change the voltage to 5 volts so that the iPhone can handle it, but I'd like to be sure.

  • I would make a frankenstein wire, but I don't know how to make one with a lightning cable. – Flare Cat Jan 14 '16 at 19:58
  • what is a frankenstein cable? – Daniel Enzlin Jan 14 '16 at 20:49

    @DanielEnzlin A highly customized cable: – klanomath Jan 15 '16 at 13:28
  • @klanomath That picture is so good... Hey, why won't it turn on? You mean it can't generate electricity? – Flare Cat Jan 15 '16 at 15:17
  • A Frankenstein wire is when you take a cord, cut it, strip it in part, and then connect the red and black cables to the power, and ignore the other cables. – Flare Cat Jan 15 '16 at 15:18

Note: this will require soldering, and I'm not 100% sure this will work.

First, take a lightning cable, and cut roughly 2 inches off of the cable on the usb male end. Strip the main wire down a bit, and you should probably be left with 4 mini wires. Take the red and black wires, and connect them to the I/O of the solar panel, via soldering.

Again, I'm not completely sure how a lightning cable works, but I believe this should work.

Here is an example how to get this done: How to make a Solar USB charger!

  • Great guide! what is the use of the diode? at the moment im planning to use a 5v regulator, and i don't really understand the function of a diode. Is it used to prevent flowback? – Daniel Enzlin Jan 15 '16 at 17:59
  • @DanielEnzlin I didn't put that link in, someone must have edited my answer. I have no idea what a diode is. Your guess is as good as mine. I'd suggest googling it. – Flare Cat Jan 16 '16 at 22:41
