>>2227473>How long can it last?it's advertised for 12 hours but i usually get 14-16 hrs on one fill (1 oz of white gas)
>And can I run it for a shorter duration like ~30 minutes for when I walk my dog at night?Yes, if you want to be economical you can put it out by sealing it in a ziplock bag. The lack of oxygen snuffs it out, and the ziplock prevents the fuel vapors from leaving. Or you can purposely underfill if you know your trip is short.
Though it's not really practical for <30 minute trips since it takes about 10-15 minutes to get up to temperature. Unless you pre-start it at room temperature
But for uses 1 hr or more it's much cheaper and warmer than the disposable packs. Disposable packs still have their place for stuffing in your boots, etc.
