We had power go out when our transformer failed on Christmas Eve. It was repaired shortly after dark, but in the mean time out came candles and hexamine canteen cup stove to make hot chocolate (because I got bored). Not EDC but handy use from my gear non the less. Plus, I got a SIGG army bottle with the fitted metal cup for Christmas, that'll go into my field bag for short hikes.
