But well, that is not really true. There are 2 versions of the charger, 
the normal heavy one with transformer, and a light SMPS-one.
The first one delivers 5.94V without load, and the SMPS-version even 
6.38V. The SMPS-one states "5.0V 350mA".

You need at least > 4.2V, since that's the voltage the battery is being 
charged to.

And of course the datasheet of the used charging regulator, Intersil 
ISL6292C states:
