Suggesting a mechanical to someone completely new to vaping / what the OP is asking about isn't helpful and could end up being too frustrating to use or even dangerous.
Bullcrap.
And what did I suggest?
A Boge XXL compatible cartotank, right? That would come with premade coils, right? That eliminates all your unnecessary worries about safety.
RIGHT?
Most vv/vw regulated APV's use unprotected batteries, mechanicals use protected = not the same batteries.
If you're using off the shelf retail coils then it's not going to make ANY difference. If it really bothers you then you can add a Kick along with the unprotected battery, but it's not necessary at all.
If I was suggesting getting into RBAs/RDAs, that would be one thing, but all I'm talking about is using a mech mod like an eGo on steroids. Since it's all premade retail toppers and coils the safety concerns have been eliminated. They are ALL designed to work well within the safe limits of ANY 18650 battery.
