    Any reason this could not be applied to a Lightning port for iPhone, or any mods necessary, different regulator?

    May work with an iPhone, though sometimes you have to do strange things with the data lines to get them to charge, depending on which model you have. Some require the data lines connecting together, some require resistors on the data lines also.

    Might be worth adding a couple of capacitors (a few uF on the input and output for stability) as most regulators specify it in the datasheet, though they usually work without just fine.
