Recommended wattage for different coils?

[BreilaRose]

When you get the Kanger subox, there is a little card that advises the recommended wattage range for the two coils included, a .5 ohm and a 1.2 ohm. I found it very helpful to have that range.

Now that I'm building my own coils, I'm wishing there was a guide for the whole range of ohms. I know it is just about finding the sweet spot, but it is nice to have a starting point and an idea for maxing out. I read earlier today about someone setting their coil on fire because they started with too high wattage, and I'd like to avoid that!

Does such a thing exist?

If you use steam engines coil wrapping calculator you can use the heat flux feture as a guide to estimate what would be good wattage for a given build. heres a link. http://www.steam-engine.org/coil.asp

You should also research the accuracy of your device as well. Many of these mods don't output even close to the wattage that they claim.

Ah, thanks! I used steam engine to build my coil, but I didn't notice that feature!

That does help!

I use Steam Engine for this also and it works well. Keep in mind also that air flow plays an important part in this. The more air you draw over a coil the quicker you remove heat from it. An atty that has a lot of air flow and you do quick lung hits with will allow more power per unit of coil surface area than the opposite.

Also, play around with that Steam Engine calculator. Coil surface area is affected by wire diameter (gauge). You can make a 0.5 ohm coil with 28 gauge wire or with 26. Check out what happens to the heat flux at the same power in these two scenarios

You will soon learn different juices like different wattage's and how warm of a vape you enjoy and don't enjoy call it a learning curve ........... best part is wire is cheap !

Ooh, an excuse to play with the new ohm reader that came today and build another coil? I'm there!

Just need to find a few AA batteries in a house with 4 gamer boys that eat batts like crazy! No matter how many I buy, we are always out of batteries for some reason!

yep; red is hot, blue is cold and green is good. aim for something like 200mW/mm2

I generally find the specified watts there are a bit high for my tastes. You can always start your power lower than it recommends and work up.

For kanthal build what I usually do, is check how the coil heats up while pre-glowing and squeezing.
1+ ohm coil
Generally start low, like 7 watt, and work your way up by 1/2 or 1 watt at a time until your vape is nice.
For 0.5-<1 ohm, sub ohm coils, you can start of a bit higher like 12-15 watt
The closer you get to 0 ohm , the higher watts you can start off with.
