Previously, you were simply using the "Ohm's plus Two formula". A simple guideline to assist new vapers how to find a starting power setting. Keyword:
guideline. There are no absolutes; nothing is written in stone.
Another simple formula is to simply begin with a lowest power setting, and gradually increase the power in increments until a burned taste is detected, and then back down a little. Again, this is a
guideline, not a rule of thumb.
A lot of elements come into play when searching for the "right" power setting. State o' Flux once said it best:
Coils, Wicks, and Vapor Production:
Vapor production comes from a combination of net coil surface area, wicking and juice type, air flow... and the wattage necessary to heat that net coil surface area. If you're lacking in any of those areas, you'll come up short.
Just a few basic points, for your consideration... some IMO, some incontrovertible fact.
- The gauge of wire and overall length of that wire is what determines resistance. Coil count is irrelevant.
- Thicker gauge wire, for a given net resistance, where the finished coil(s) physically fits in the atomizer, provides the greatest surface area.
- Thicker wire, for a given net resistance, runs cooler than thinner wire, for a fixed wattage value.
- For a given net resistance, thicker wire requires more wattage to obtain the same heat flux (coil radiant heat) as thinner wire. Thinner wire, although it reduces surface area, can be used to raise heat flux where adjustable wattage (mech mod) is not an option.
- Higher wattage, for a given net resistance, produces more heat, and requires both better air flow and optimized wicking.
