how do I know what watts to use when building my own coils in my rda I’ve just starting building I just wanted how do I know what wattage to vape at ideas anyone plus I would like to know if there’s like any apps or anything that could tell me what wattage to use for which ohms (resistance) thank you
Trial and error. Just start low, and work your way up until you like the vape you are getting. Calculators can tell you a generic guideline, but not what will be good for you personally.

As said above, its a process of trial and error. Assuming you are using a variable wattage regulated mod, start very low on the wattage setting, and increase the wattage setting in 5 watt increments. When the vapor becomes unpleasant or too hot or even tasting a little burnt, back down 5 - 10 watts.

You may find that certain flavors do better at slightly lower or higher settings. That's the beauty of a variable power regulated mod, you can adjust your wattage settings on the fly.

Does your battery device use an internal battery or external batteries? If external batteries, be sure to use a battery model that can give you the wattage you need.

how do I know what watts to use when building my own coils in my rda I’ve just starting building I just wanted how do I know what wattage to vape at ideas anyone plus I would like to know if there’s like any apps or anything that could tell me what wattage to use for which ohms (resistance) thank you
If you're using simple round wire builds, the Steam Engine calculator will help by giving you wattage recommendation based on a the heat flux that wattage will produce. Beware however that with fancy coils, such as multi-strand twists and Claptons and so on, Steam Engine doesn't account for wire surface area that's "hidden" (in contact with other strands) and will thus under-estimate heat flux for what I'll call the "effective" surface area of the coil.

In any case, "start low and work up" is good advice.

Drew, this should give you an idea…

MacTechVpr's Tensioned Rebuild Central

I would start on the higher side of green if you're unsure. Get a good wide bore drip tip for your RDA and learn how to slipstream some air as you draw. Something we did rather intuitively and asbsentmindedly with analogs. It helps to moderate the diffusion of vapor after it's been produced at the coil as well as the apparent temperature. These things will brighten your vape.

Learn to rebuild an efficient coil and nirvana will happen.

Good luck. :)

Pretty sure you've got the answers you're looking for already but I'll add a small example of what i use generally (i only use round wire build)

A .4 0hm kanthal dual coil for me is best around 40 watts

Usually i use stainless steel at .3 0hms for about 50-60 watts

All my coils are 3 or 3.5mm only no smaller no bigger. The size for me usually depends on the deck size.

What do you mean, "We"? Fallacy of the ambiguous collective. I've never done that with tobacco cigarettes. ;)

Merely a figure of speech, we. It's almost impossible not to draw any side draft, I'd think. It's only a matter of degree and awareness. A rather naturaly intuitive reaction rather like the breathy sip of a hot tea. We never sucked on a cig like a Wendy's straw as some do the vape. Then again, some may like that sort of thing. And I'd hate to have people obsess about it. Although I must confess a penchant for observing the languorously drafty draw of the gentler of the species.

Good luck. :)

Indeed. This is the main reason I use an app called Vape Tool Pro for fancy coil calculations. Very good app IMO.
