This a question I ask pretty much every vaper I meet. How much liquid do you vape in a day? Right now, I'm vaping around 50ml a day using the Smok TFV4 tank. That's up from around 30ml a day on an RDA.
50ml?! Holy crap. I'm pushing 20ml a day tops if I'm writing, 10 if I'm doing something else. I primarily use drippers with low ohm dual coils too.
I am an "all day vape" (or ADV). I use about 15-20ml in an Aspire Triton tank on a Cherry Bomber box mod. I started vaping as an aid to quit smoking. It worked and I am still vaping with 6mg of nicotine, but I am not smoking all of those other chemicals from the cigarettes. My ADV is Apple Pie.
