You are misinterpreting my question. This is the first Im hearing that this is meant for 3.7v vaping. I guess I assumed if the resistance could be adjusted, so could the voltage. This is my first rebuildable. I watch all these vidoes and I do exactly as what I see, and I'm not getting any air flowing thru my device. I am just trying to figure this thing out. I am not trying to piss anybody off. I have to suck till I'm red in the face, seems to me there is an airflow problem.
I have since loosened the atty from the PV to the point where it is just barely making contact with the current, and it is wobbling around atop my PV, and now I'm getting better airflow. Could you please tell me how air gets thru a tank full of liquid? What am I missing here?
