There are several factors that go into satisfaction from vaping and how it is achieved. There are also options that involve factors we rarely consider when building rigs and coils.
As far as satisfaction goes, I vape 18 mg juice, I used 24 for years and throat hit was (and mostly still is) a huge factor in satisfying my urge to vape, clouds are very low priority for me. My buddy that I twist coils with is the opposite, he needs to see a cloud but a mild throat hit is good by him.
Be very very careful using more than one battery, you should check out the safety thread on it.
That said many rarely take into account the full range of thermal effects occurring in their devices, I certainly dont, its too much math for me. We tend to focus on electrical terms that create those effects.
A say 3 ohm coil made of 20 gauge kanathal would be monsterous in size. Turn it up to 50 watts and its running at 12 volts (approx). Think about the size of that coil, heck think about two six ohm coils running at the same power.
Many rda s don't have deck space for that much coil.
The surface area of the above coils would be large and yes they would probably take a bit to heat up, but the mass of them relative to the space they are in vs the amount of juice and wicking causes them to have an abundant thermal effect on their surroundings. Once they get hot they will also take some time to cool.
The same three ohms in 30 gauge is tiny, if you really bury it in wicking and submerge it in juice it will still work but with a lot of spitting and eruptions with good vapor coming only when eruptions of juice on its surface let out the heated material.
A flourecent light bulb has particles in it that are over 1000 deg f. Heck its plasma in there, but you can touch the surface because of the thermal dynamic occurring between the relative interactions of the materials present.
Vaping is the same way. There are several ways to achieve clouds and throat hit and flavor. If you want to be an all time world champion cloud blower get a 260 watt device and put the lowest ohm coil on it that it lists as safe made of the most surface area you can fit. Part of cloud chasing involves your lungs too, your biology may limit a record. Remember that satisfaction takes many forms and success with these items is more than just the electrical end of the devices calculations. If your having too much trouble getting satisfaction consider some other approaches. Oh Don't Smoke The Juice! Get it too hot and you will be burning it, its probably bad for you, real bad!
