The power goes out and you're holding a flashlight that lights one corner of one room, or a phone you can't afford to drain. The Survivor puts out up to 600 lumens for up to 130 hours on a charge, and recharges most phones 2 to 3 times. It runs on the sun, so there's no battery to find dead. Buy one, get a solar Lantern free, because one lantern only covers one room.
