I grew up learning to use Coleman lanterns and stoves properly. Those have all gone away now in favor of LEDs. I, too, am a fan of rechargeable batteries; why anyone persists in using alkalines (alkaleaks) is beyond me.

Several of my lights also function as modest power banks, allowing me to keep my phone (camera etc.) charged. Moving and storing electrons is now the name of the game.

I can recharge batteries from the grid, either of our vehicles (one of which is a Prius - no worries there) or from portable solar panels.

This is a much safer and convenient source of power than white gas or similar.
