There are just way too many variables to accurately determince just how long a full cartridge will last you. It will vary depending on the type of filler material in your cart, the humidity, air temperature, viscosity of the e-
juice, just how much PG or VG or combination of both, type of e-cig atty involved/used, voltage used, how you draw, etc.
I use the PTB
mod (Made Easy!) and normally I add about 7-10 drops, about the time when the flavor and vape tends to weaken just a bit. I vape pretty steady although I do wait at least a minute between vapes to allow the atty to cool a bit and the wick to absorb some e-
juice for a good vape. I might get a good dozen or more good long vapes before I feel the need to refill.
Every e-cig is different so your results may vary quite a bit.
