Ok, so I have only been doing this for a couple months, been cigarette free for a month and a half. This is whats known as sub-ohming. These people use mechanical mods, which are metal tubes that have no circuitry inside of them. So the power they get is straight from the battery in the tube, you hit the switch (mechanical as well) and it dumps the batteries power into the atomizer you have on top. On top they have RDA's (Rebuildable Dripping Atomizers) where they will build their own
coils with A-1 Kanthal. They sometimes twist the kanthal, make extremely small coils called microcoils, nano coils, or even super nano coils (which are super small and heat up very quickly). Because there is so little wire these coils have super low resistances (less wire the lower the resistance) and it produces a lot of heat which vaporizers their e-
juice very quickly. These builds are for experienced users only, because it requires very strong batteries with very high amp limits, otherwise you can stress your battery and venting can occur, which is very dangerous. You also need to know HOW to build coils and have a good understanding of ohm's law. If this is something you would like to get into, start by building single coils at high ohms and work your way down. And use HIGH amp batteries like the Sony VTC4 or the Efest 35 amp batteries. People see these clouds and jump into sub-ohm levels without the proper knowledge and proper equipment and put themselves in danger. It also hurts the
vaping community because people could potentially get hurt. So do your research. I also want to do this one day and even with knowing this much I am currently only building coils above 1 ohm in my russian 91%. I do not even own a mechanical mod yet. Check out RIPtrippers on youtube for different coil builds, if you think this is cool his crazy builds will blow you away. And talk to people on ECF, a lot of knowledge in these forums and a lot of these builds come from the people experimenting on here.
