I know a few people with the Bilote CampStove, and have used one a few times. At 2 lb it is not that heavy, and when compared to having to take along a litre or two of white gas, or a few butane canisters, it is very light
There is usually no problem around here finding fuel for them. One buddy gathers during the day finger sized pieces of dried wood. The little sucker heats up quick, as once it is warm, the generator
provides electricity to power an onboard fan, the whips the flames into a furry.
The charging of electronics through its USB port does work, and my friends keep their GPS and music player charger with it.
You can get a grill that fits on top of it too. Works great for meats and veggies.
It is first and foremost a stove with a heat powered fan, the USB charging is just a side benefit.
All-in-all, a very well thought out and designed stove, and for about $120, something I have considered. Would I bring it in my trailer....I doubt it. It would be for backcountry use only.
