OMG and I thought that when I go over 2 ml a day it`s too much
Sorry I cant help you much with your choice but I just wanted to warn you that I`ve heard from users that mods are juice monsters so you`ll go way beyond your current daily doze...
I`m currenty happy with the 510 and battery life is the only con...
Good luck with your next PV
This is how myths are created, mods are not juice hogs, some are
IF they use 5 or 6 volts settings, the others, (most) at 3.7 V consume aprox. the same amount of juice as a factory e-cig.
I am also on the league of heavy vapers at 6-9 ml a day.
I use both nic and no-nic juice, it's not about the nic, it is about how long you are using it.
In my case I rarely put my e-cig down and when I drip in my cartridge (6-7 drops on an 801), I consume that in about 8-10 puffs, that means that I have to drip about every 8 minutes average.
That is why most batteries will not last me long enough to even take the time of charging them. I always use 18650 batteries which are big (2.5 inches long X 3/4" diameter), and only when I'm out and about I use regular batteries (3-4), because I don't vape even half as much.
So there are so many variables to how each of us vapes, it is impossible to measure. That is why we use the ml as a measure to make it more understandable.
How hard the draw, how many puffs in a minute, what type of atomizer/cartridge, voltage, etc. all these affect the outcome in ml.
