Well if you run the 5ml Nautilus you will likely change your mind fast about not going over 11w since that one seems to run best at 13w-17w! The Atlantis starts off at 20w but gets going at 30w. The specs show 15-30w for the Kanger sub ohm and the latest intel on the Horizon Scion Bottom Quad Core atomizer 3ml tank is 10w-55w seen in the wholesale vendor's info. That also has Japanese cotton wrapping on the four coils that are stacked vertically not horizontally like a dripper.
In most cases you have to look at the design of the tank to see which wattage range is optimal for it. The Smok
tanks generally have been running in the 5-11w range except now for a few brand new ones out that run on the 30w mods. The Nautilus isn't a sub ohm neither are those while the Scion sees four different coils available for it. 0.2, 0.4, 0.6, and 0.8 The main problem at jumping at that tank is "Limited Edition"! That means it's only around for so long and Horizon discontinues it. That will make getting replacement coils for it later a bit difficutl?
Now the advantage while not pursuing Cloud Making as the ultimate goal but wanting better vapor as well as flavor has been not having much out besides RDA, RBA type rebuildables to work with as far as sub ohming. The generally seen tanks are limited by the coils which were mostly designed for 3-15w max Vamos and VV batteries going up to 4.8v not 7v and above. I still use the Tumblers here on eGo-V 3-15w batteries as well as on the four iTaste VV v3.0s I bought on Black Friday a year ago.
I keep a battery on at all times since that have a tank full of one of the menthol flavors while I can get more out of other flavors at times much better on the Nautilus or Atlantis tanks being better made to begin with. This has been the findings here at least. I could care less about whether a tank can make a cloud since that is nothing new anyways! Rock groups and other live stage performances have used fog makers for a few generations now! Where does Hollywood get all that fog in movies? etc.
