Butane Camping Stove for Hot Water for Tea & Coffee & to Cook During Windstorm Power Outage Recently

I refill the butane cartridge 8 oz, with a 16 oz propane torch tank, that I refill from the 20 lb 4.6 gallon barbecue tank, using special adapter. I freeze the receiving tank for 4 min to cool it so that the gas transfer from the warmer mother tank chills & liquifies the gas in the receiving tank. I am well familiar with the vapor pressure & properties of butane & propane & have a background experience extensively working with both & college educated in chemistry & physics & much more & do so with special high quality adapters very slowly & very carefully.
We limited using the stove to less than 30 minutes to avoid CO poisoning & have a CO monitor on the wall nearby for added safety. This was only done a few times per day during the 4 day power outage.
