I stopped vaping a few years back after vaping since 2010 so i'm no newbie. I used a Lava Tube by Volcano with 5 volts and a CE 5 type cartomizer. No one speaks of e-cigs in terms of volts anymore and I'm kinda lost picking out a new system. I used a 3.0 ohm coil with between 4.5 to 5 volts so wattage is anywhere from 6 to 8 watts. I cannot find 3.0 ohm coils anywhere but that's the experience I like. I go to the e-cig store and ask the guy what he has that works with 3.0 ohm coils for 5 volt vaping and he looks at me like a deer caught in the headlights. What choices do I have to fix this problem? Thanks..
