So, I've been using my e-cig exclusively for about a month. I had a single battery for my PV, so I was using the thing for an hour or two, then let it charge for an hour. I was going through 1.5ml of liquid per day.
Well, that's until about 5 days ago, when I decided I should make myself a passthrough, so that I won't have to wait for the battery to charge. Quickly got one made, by using a spare charger, a switch, and a dead battery. Since then I have been consistently going through about 5 or 6 ml a day and it keeps increasing
Now I'm thinking of going back to using batteries, as they give me a few hours per day vape-free and reduce my liquid usage about 4 times. It's not even that I NEED to smoke it's just the constant habit of picking up the PV and taking a puff every few seconds, especially when you don't have to think about the battery running out
Still, off of my 1pad habbit and couldn't be happier
