    Mobile LiIon battery charger(?)

    so, is it possible to make a mobile charger from some LiIon battery with greater cap, like ~3000mAh (could be lap-top battery or standard e.g. 18650), to charge smaller LiIon 3,7V cylindric batteries, like ~500mAh? plz answer, because this will mean a lot to many ppl.
