Watts is subjective. I have a 0.32 ohm setup and I vape at 75w normally, but I can take it to 100w on my mod and it holds up fine and pushes 5.6v, although the tank gets pretty hot. The higher ohms you go the less wattage it takes. So yeah, on my 0.32 ohm Clapton build I can take it to 100w and never get a leak. But if I built a 0.6 ohm build I would be pushing some serious voltage at 100w, and could, possibly, get dry hits. I haven't tried higher ohm builds yet, but when my black aromamizer gets here I'll test a few builds on it. I just think my wicking method is perfect, for me at least.
