Really new to all this and just want to get a grasp on things. What is the point of insanely high watt box mods? I heard that the higher wattage the better? But then I just saw on here that it just is a miserable vaping experience to vape at abnormally high watts. I'm lost here and I just need some advice before I purchase the components to build a VV box.
Generally clearomizers and carto tanks have higher resistance coils (1.8-3 ohms) made of thin wire and little wicks. Rebuildables like a kayfun or dripper might have lower resistance coils (.5-1.5 ohms) made from thicker wires and much bigger wicks.
Little wires need less energy to heat up quickly. Thin wicks can't feed juice to the atomizer fast enough to keep up with higher power. Higher power on smaller coils and wicks gives a burnt taste.
Bigger wires need more energy to heat up quickly. Thicker wicks can feed juice to the atomizer fast enough to keep up with the higher power. Higher power on larger rebuildables gives more vapor and denser flavor.
So, 9 watts will probably taste burnt in a pro-tank, but 9 watts in a kayfun will probably be weak.
Keep in mind that higher power will use the battery faster.
Putting this all together, I usually run my rebuildable kayfun at 2.4 ohms and 6 watts. The thinner wire used to get that higher resistance coil heats up sufficiently fast at 6 watts. However, I used a thick wick to feed the atomizer quickly. I get a great vape off this setup without hammering my battery (2 days on an 18650 in my Vamo).
The advise you need is predicated on what type of topper you plan to use. If it's a premade coil for a clearomizer/carto, then 15 watts will be more than enough. If you intend to build your own with thicker wire and wick, then 30-50 watts is probably a good max (until you decide otherwise).
As a datapoint, when I use my dripper, I'm generally using a coil around .8 ohms and 15-20 watts of power, so 30 watts would be good for me.
Hanzo.
