not so much for out in the bush but for hurricane preps.... have been procuring adapters for a Goal Zero 7w solar panel... just received a Nimh charger controller with USB, 12V, and 120v connectors for AA... 8 pack of AA Sanyo Eneloop cells, probably later C and D adapters...12v male plug to battery clips for a auto battery..
my older Grundig radio is crank to Nimh cells, and AA powered
digital portable TV is 12v adaptable
12v ventilation fan with female adapter off auto battery
Dietz Air Pilot and Little Wizard kerosine lamps
toying with a BYU funnel solar oven next week (making ice cream using black body radiation would be pretty cool...pun intended)
my 4x32 ACOG has an exit pupil diameter of 8mm, and really sucks in light
