i have an ipv2
1. if i build a dual coil rated at .8 ohms, does it matter if i use 25 watts or 50 watts?
2. the lower you go, the higher watt setting? to produce more vapor?
1. Yes, it matters, absolutely. Aside from the fact that wattage is doubled, you need to make sure your I's are dotted and your T's are crossed when you get into higher-powered
vaping, whether it's on a regulated
mod or if you're chasing clouds with a low sub-ohm coil.
2. Sometimes, but not always. Yes, generally speaking, higher power applied to lower resistance can produce more vapor, but there's a lot of other things that go into clouds. Coil design, wick material and placement, air flow, and
e-liquid.
I can take a 1.6 ohm Aspire coil and burn it out at 30 watts, or a hand-wound micro coil on a rebuildable atomizer at 1.6 ohms and vape all day long at 30 watts.
Was there a specific atomizer/coil combo you were curious about?
