This was clearly my fault, a bit promoted by the wrong pictures in the
manual of the VARTA Digital USB Charger: the pictures show the LED of
each cell 'on' when it is full, while the manual stated correctly that
the LED of each cell is on while charging and blinking on full;
in short: the cells have been nearly empty :-)

I've fully charged now the four AA cells of 2700 mAh and USB-out is
working as it should; the shows 1000 mA charging rate;
this pack of 4 cells each 2700 mAh give you around 10,000 mAh

I will do  more tests and update the Wiki after this about this charger;
