Wattage / Resistance

[Sporkdroid]

First off forgive me if there is already a thread on this, I couldn't find one searching.

What I am trying to figure out is if there is a formula or something to figure a similar power when vaping.
When vaping a .5 atty at 40 watts seems be be similar to vaping .15 at 80 watts.

Is there a way to figure basic starting points when using a different resistance atty and where to start your wattage?

Thanks!

I usually go by voltage...If my ohms are lower I need more power to reach the same voltage...For example I have a .42ohm coil build in one tank that gives me 4.2v at 42 watts of power...So if I went down on ohms id need x amount more power to reach my 4.2v which should give me around the same vape...If you can establish a voltage you find that gives you the vape you want then its easy to set wattage for any ohm coil you use or build.

Thanks that seems to be a good starting point even with different atomizers.

The only difference I consider if using different tanks or RDA's is rather or not it has the same, more or less air flow..4.2v might be good for me on one tank but too hot on another..but ive established 4.2v as a range I like providing I have the air flow...As a reference it seems to work for me personally.

It would have been nice to have a formula to calculate how good a vape would be based only on resistance and wattage, but it doesn't exist.
There are many variables which effect flavor, like: coil surface area, coil mass, coil positioning, coil heat capacity, coil heat flux, coil material, amount of airflow, airflow directionality, vapor amount, vapor density, juice composition,juice chemical reactions between flavor chemicals, PG/VG ratio, chamber volume, chamber shape, your own personal preference.

Simply putting it, the bigger the chamber of your atty, the denser the vapor needs to be to produce good flavor which would require a higher mass coil, which would require a higher wattage to function properly and have good ramp up time.
The material the coil is made of and it's resistance also effect the ramp up time.

Vape tool pro is a android app and has a sweet spot calculator in the coil calculator on it. It's pretty handy app. Not sure if that's what you are looking for but it's on Android not sure if Apple has it.

You can put your coil detail in steam engine and it will give you an idea of how warm the vape will be with a simple picture at the bottom
