Don’t you just hate being stuck out in the woods without any power and your iPhone is about to run empty?
Get yourself a K3 from Kinesis Industries!
This gadget can charge your cell phone, MP3 player etc., either by solar or wind power. The K3 is somewhat waterproof but otherwise heavy duty. It will provide 30 minutes of talk time or 300 minutes of music after one hour.
When full, it can charge a cellphone about 5 times and an iPod or similar about 10 times.
It has USB port built-in and comes with various tips and an inside space for storing them. If you need additional tips (converters), you can probably find them online at $10-$15 each.
I seem to recall a price of around $100 for the K3 itself, but I’m not sure though.
The Kinesis K3 should already be available, but probably not in all countries.
