For example, if you're a lower level player who hasn't yet unlocked a particular monster of townsperson and wanted to banish or trade with them for their rewards, then you may want to visit a friend's map that has those unlocked and banish/trade on their map. Doing so counts as a charge, so your number of available charges for that map will decrease.
