That’s a seriously cool bit of kit if it works as promised.

Wondering if the amount of extra gas you’d need would be more or less bulky than extra batteries or a solar panel.

It does look cool. You would walk around pretending it was a light sabre wouldn’t you, sshhhhhhwwwaaaaaaarrrrzzzzzzzz.

I;ve got a biolite and it works really well e.g. on the beach we often cook mackerel we have caught – the bonus of charging a phone at the same time is great!
