Many things come together to figure e-liquid usage
Ability of wick to draw in fluids to coil
Temperature of coil in operation - Hotter = faster vaporization
Strength of draw
length of draw
Number of draws in a given period
and so forth
Ce4 is about middle of the road, or average if you will, for clearomizers.
If you are concerned with usage - Vape less
If you are concerned with keeping smoking at bay - relax and vape.
