Hey my name is Matt and I joined this forum to look for some help. I like to buy top of the line and at my local smoke shop I was recommended an 18650 hell hound mechanical box mod @150 watts. I also bought a vortex atomizer for the tank and some juice for it.I bought two batteries and a charger for them. I charged each one for about two hours. I out the liquid in the tank, hope I did it the right way, filled it about 65-75% full up to the line. I screwed on the tank and put the batteries in after I let them charge for a couple hours. I hit it sometimes I barely get some smoke and sometimes I get no smoke at all. Any help please???
