Another device that I thought would be worth trying out with the generator is the laptop from the One Person Per Laptop project, the XO-1.
I have been fortunate and have acquired two of these XO-1's (sparky and sparks). Both of them were pre-release versions and have been superseded in various ways, but they still attach attention when brought out on display. Kid's just love them.
Both XO's were able to be run via the inverter from their charge packs. (One of them has an issue with it's battery taking a charge, which is why it is off in the photo.)
When I get some more Anderson connectors I'll look at how they go when connected directly to the 12v-14v supply.
