1.5 gram CO2 cartridge source?

Could these be used to fill "air mattresses" for backpacking? I have seen some like this but don't know if they were 1.5g or where they came from.

Thanks for the reply. The answer is "maybe", but certainly they don't contain enough gas to fill an air mattress all by themselves. There are ways using venturi designs to have such small cartridges multiply the amount of air they can force. One can apparently get many times the volume using such designs. But I don't think this is what these mini cartridges are mostly used for. More likely, those air mattresses are using 8 gram or the more common 12 gram sizes. The 8 gram size seems to be often used for selzer bottles. The 12 gram kind is used in air guns to the exclusion of all other sizes as far as I've been able to tell. The kind I'm talking about are not much larger in diameter than a lead pencil.

Your douts are stupid. But I do not advise you to get sorce of this device., better thinck your future .

. . . providing further proof that there is a fine line between genius and insanity.

How about life vests or personal flotation devices. Their internal volume might be about right for these smaller cartridges you are looking for. The tip off might be if it has a threaded neck on the actual cartridge.

I have seen small replacement cartridges at boating supply stores.

Good Luck
