The SpareOne Emergency Phone is the world’s true emergency phone with a battery that can last 15 years. It uses one AA battery which is included and doesn’t even need a sim as it has an emergency call button. It also can be used as a torch for 24 hours, has a talk time of 10 hours and operates in temperatures of -30 to 60 degrees centigrade.

What a clever concept. Simple idea too. Just not sure who will buy this and when.
