lets face it with all the electronics we run new battteries are becoming a burden. here is what i have come up with . solar cells are great , but they are bulky for the roll out bundles .some brands can power a laptop but they weight is a concern to hike with . you can build your own .with the right resistors and blocking diode well done . kinda .it could take all day in direct sun light to charge (2) 2700 mAh AA lithum batteries at a safe rate. Power Film works ok . you can tie it on your pack just don't scratch it . they also make military fold out solar rolls too . there are a couple companies make these products. power peg just came out it kinda goes on the kinetics . as you do activity it builds power to charge what ever you have . i don't remember all the spec but sounded good . i do carry a small hand crank generator made from an old open face fishing real . i took out the part that made the spool go up and down and fixed the spool from moving. next i took off the bail and screwed a magnet to each both matched .(i used 2 kolbalt)then i trimed down the spool thin and wrapped it with thin copper wire make a good coil . i mounted it to a handle and add my resistors and verious adaptor. i burned my arm bad when test this thing. i had it hooked up to some 6v lights and they blew and the wires came unsoldered and burn my arm .so it is has the ability to reach 12v and higher and at good amps just realing faster. just woundered what you guys have come up with.
