Hey /out/, I want to help my relatives in Puerto Rico by sending them some supplies once the postal service gets going again. Power is still out in their area and their fuel supply is limited, so I wanted to send them things like hand-crank radios and lanterns, as well as some flint and steel in case they have to start lighting fires the old-fashioned way, should their supply run dry. What else should I send them that they could use in such a dire situation?

Keep in mind, I have no survival experience, so I don't really know about these kinds of things.
