A portable solar powered power generator? Why not? That is practical. I have a 1.05KWH version as an emergency power supply in the event of a major earthquake since my region is susceptible to earthquakes. I can think of many remote communities that can benefit from this where reliable electric power has been inconsistent. There are several different very good model brands in the market,take some care in choosing the right model for your friend's needs @flawless-dee
