    If its anywhere it'll be in the developer notes.

    Apple has just reorganised their developer web site
    <http://developer.apple.com>, making things more difficult to find. The
    hardware docs are not mixed in with the software docs at:

    You can also often find the voltages in the repair manuals, at least what
    a useable battery should have. The power adapters will be different
    (higher).

    Some adapters have more than one pair of contacts, these may have more
    than one voltage.
