I think the characteristics of LiIon have nothing to do with this problem,
since there very likely is a switching power supply and charge controller
between the raw USB power input and the internal batteries of the phone.  S=
o
as long as you can produce a voltage within the normal USB range, the phone
should take care of the rest.
