I got one of the Zippo hand warmers today and it's a great wee thing. I've had it running for twelve hours now on lighter fuel and it's still roasting hot.
Has anyone tried them with a different fuel? I was thinking Paraffin (always have some with me for my Primus stove) or Meths?
Taking a small bottle of lighter fuel is no hassle as it doesn't use much but I'm just curious about alternatives.
thanks and atb,
