I general favor sleeper coils. They are easier to work with, springy and lasting. Might want to try this:

Look behind you.
All these coils (tiger/alien etc) are more aesthetic than functional in my opinion. Gives you the bragging rights when you compare coil builds with other fellow vapers. However some swear by these coils and claim that they give more flavor/vapor production. To each his own.

Indeed. Simple kanthal/claptons builds work good enough for me.

Need some help..

I'm using evic mini and Tfv4 mini and just got some kanthal a1 wire 26awg...

Manage to get 0.65ohms with 4 wraps.. Find that I manage to get a lot of vapor with very low watts (12 watts) but the taste is gone... So read that more wraps gives more surface area which means more vapor and more taste.. But it will increase the resistance to quite high.. And with evic mini, it's using a 18650 battery which is 3.7v.. I used ohm calculator and realized that I only require to use a very small amount of wattage.. So how is it possible for u guys to vape at high watts with high resistance? Won't it burn coil out very fast?

Please do show us your calculations. With only 1 variable (that's your resistance), i am curious how you derive your conclusions.

Maybe I calculated wrongly..

So what I always thought was that the voltage is fixed which is 3.7v as I'm using a single 18650 battery regulated mod.. So on the online ohmscalculator website, I will put 3.7 volts which is fixed. Then I will input the resistance from the coil I built, for example 1.5ohms..

After inputting 3.7 in volts n 1.5ohms in resistance, I get 9 watts..

So I'm wondering how some people can vape at over 20 watts with the similar inputs I got..

3.7V is your terminal voltage. I think you might want to read up more about power law before pushing your mod or coils. More important to get basics right before doing anything else. Information is readily available online. Google.

Sent from vapour clouds above
I have been googling even before I get the mod but I just don't get what it meant.. Especially the voltage part.. But it's okay I will continue to go do research on it..

Thanks..

@ReapersCreepers lol, you just need to go to steam engine and the coil wrapping section. After which input the variables and the wattage to get the heat flux which i usually do between 170-220.
The voltage part essentially isn't applicable to vtc mini since there's no voltage mode, they use calculation against fluctuating resistance to get the wattage(yes kanthal do fluctuate but not by much as compared to TC wires) to sustain a stable wattage. Voltage calculation is more applicable to mech mod as of now.
