I've just got into rebuilding coils on a Octopus single and a Trident Clone double. I've had good success with both. The resistance I aim for is 1.8 to 2.0 ohms with #32 Kathnal both for single and double coils. I've been hitting the targeted resistance dead on. Watching many you tube videos and personally being instructed by an experience builder has really helped me start right. Plus I have an electronics background, so understanding the physics of Ohms law is easy. My APV is a Seigeli mini-Zmax.
I've noticed that with the single coils I get very good flavor comparable to what I would get from a Kanger mini-protank2 or Ts3. I run the same power of 8 watts with the single coils as compared to the tanks. I run about 11-12 watts for the dual coil setup to get the same effect even though the resistance is 1.8 to 2.0 ohms. Much more air flow is needed with the dual coils because more surface area is vaping the liquid. I've noticed that air flow is important here. With the dual coils, I have to mostly "lung draw" since more air is needed. Of course more vapor is produced.
I'm wondering about something though. There seems to be a longer lag time or "hysterious" in heating the coils up to vape temperature with the dual coils since there is more surface area to heat, hence more liquid to heat. Am I correct with this? The resistance of course is the same. But to heat the more surface area of wire and more volume of liquid, a higher wattage is needed for dual coils. Again, is my observation correct?
Personal preference for me is to do single coils, use less liquid, less air draw and get same great taste, plus longer battery life. I like rebuildable atomizers due to the convenience of quick change overs of different flavors throughout the day when using cotton wicks. In the long run, I save money rebuiding coils than just buying coil heads.
What are other peoples observations? Are they similar to mine?
