I'm going to call the following 'phantom leakage'.
This happens to me from time to time and I can't really figure it out. Doesn't really seem to matter which tank I'm using, every once in a while it will leak. Badly.
In my coat pocket or perhaps in my hand.
The odd part is that same tank with that same coil and the same juice will work just fine without leaking for weeks or months after cleaning it up and blowing it out.
Then out of the blue after a month or so... Boom. Phantom leakage.
I happened once on my atlantis and never again. Just recently got the sub tank mini and last week it dumped half the tank into my coat pocket, but not since. Not even a drop. Been through 5 or 6 tanks since. Same juice, same coil.
My best guess is that it's temperature related. I vape outdoors at work and it's been pretty cold lately. I'm thinking that when I go outside, the sudden drop in temperature causes the juice to contract in the tank pulling in air. Then when I got back in, the heat causes the juice to expand and build pressure causing the juice to wick into the coil and drip down the airflow channel.
Now if I could confirm that, I'd be a happy camper as it would make sense. But alas, it happens so infrequently, that I'm not sure that's the cause. If my theory were right, it should do that every time I vape outside in extreme cold (which has been pretty often in the last month) and I could avoid it somehow.
