Question about warm vapes and lower resistance...

[maxmonster]

I was always under the impression that lower resistance coils gave a relatively warm vape. As all the low res coils I've wrapped were too hot for me the handle when I first started rebuilding... Until this past weekend when I just tried a flavor on my friends nimbus. He had quite literally about a 2.5 inch long 2mm wick with a 28 gauge wire wrapped once around which he claimed was at .3-.4 ohms. At first I said no thanks because I assumed the vape was going to be warm for me but I tried it and wow it was cooler than my 1 ohm wrap! I am running an IGO-W with two 5/64 holes and two coils wrapped three times around with 30 gauge wire with 2mm wick tripled over itself. I asked if his battery was dead and he said he just changed it. So how could this be?

I'd assume this is because you simply cannot heat the same volume of gas with such small surface area.

A rather broad analogy would be trying to boil a pot of water with a stove top at 600f vs a butane torch at 2000f. Sure the torch is much hotter but it just doesn't have the coverage to heat all the water. The coil has more than enough power to vaporize the juice but cannot heat the volume of air passing through the chamber, whereas larger coils (even at higher resistances) have the surface area to do so.
