There really is no charango for left handed people, what varies is how the strings are placed. If you are left hended there are two posible options: Chord your charango in such way that the instrument results with the adequate tuning, in other words, turning around the order of the strings. In the case of concert charangos, the bonefret on the bridge usually has many uneven places, so this type of charango cannot have the strings turned around as the bonefret must be adequated for the new order of strings.
