We keep a windup in the BOs and a windup radio. Hope to do a solar panel for field use. It will power a mini fridge, recharge batteries, etc. MJAngier (another board) has a setup similar to what I want to fab.
I have a few of the ETON radios and they work great. My mother uses one for work on a daily basis and it has held up for over a year before she decided to get a new one (not because it was broken just wanted the new led version) I would recommend it any day. how ever i like the older versions best they seem to be made a little better plus you can replace the light bulb when it goes out not like the new LED ones i have seen.
