I think the best way to ask this is not really how many puffs, but how many cartomizers or how many mls of juice per day, depending on the mg. of the juice being puffed. I use about 3mls of juice per day when dripping on a 6v mod and that is vaping practically nonstop from morning until night. I used 18 to 24 mg juice.
When using the cartomizers, I'm more conservative and try not to vape quite so much. But I can go through... 2 a day if being conservative and that is 18mg cartos. But then, I'm dripping in between with the mod.
So, if you say a puff every 60 seconds... 16 hours of waking time...
16 hours x 60 min. = 960 minutes times 1 if you took a puff each minute. 960 puffs a day, no allowance for not vaping because you didn't want to do it (as if), showers, meals, fingers on the keyboard, work, etc. So half of that would be approximately 480 puffs a day. I consider this to be heavy vaping, though no idea of how many packs of cigs this could equal.
OK, no wonder my batteries are always on charge. LOL
