No need for a generator when you can charge while you cook!

The Bio-lites (whether the 'small' portable version or this larger 'camp' version) have a battery.
It's almost certainly a Li-Po with a shelf life of about 5 years.
That's a lot of money to spend on something that's not going to work very well in a few years (it's unclear whether it can still charge at all when the battery dies).
While a solar panel is probably lighter and cheaper this will work when you're hiding under forest cover somewhere.
I'm still not spending £270 on one any time soon.

Lightspeed, most devices require charger for many minutes (30 to 240) to charge. If you've ever tried to use the hand operated dynamos they become tiresome to use after only a minute or two.
