Can I get a free replacement iPhone charger since the cord has stopped functioning?

Can I get a free replacement iPhone charger since the cord has stopped functioning? We've had the iphone 5 less than two years and have been very careful with it (mine is in near-mint condition right now), but my husband's charger as well as mine decided to stop working properly in the last couple of weeks, so now we have no reliable phone chargers. Is there a way for Apple to replace these?
