Portable mobile charger

i will connect those 1.5V batteries
maybe that will work :)
& maybe it will also not affect my mobile battery :D
Not sure what you mean by not affecting your mobile battery, but even with 4-AAs, you will still need some kind of voltage or current regulation.

Never charge a battery directly from another, or from an unregulated supply like a wall-wart or other power supply.
