A question

[bman1977]

Ok. So i'm trying to start understanding volts, watts and ohms. I'm using an Innokin Cool Fire 1, a kanger tech pro tank 2 with 2.2 coils. Kind of new to all this. I quit analogs one year ago using Green Smoke and recently made the jump to the Mod with my Cool Fire. I'm happy with it so far but just wondering if i'm using the right coils and just want to make sure i'm getting the full experience with my setup. Don't really want to get into any rebuildables yet but will eventually. I use 18350 and 18650 batteries (18650 with an adaptor) This is also my first post after being the creepy lurker for a while. Any tips?

electricity and water behave very similarly
picture a garden hose in your mind, this hose is the wire.
water flowing in the hose is the flow of electrons.
Volts is the water pressure
Amps is the speed the water is moving at
and Resistance or "Ohms" is the back pressure caused by friction.
it takes 1 volt to push 1 amp through 1 ohm of resistance.
Volts x Amps = Watts
the Watt is the most common unit of power in the vaping universe.

Ohm's Law for Dummies - using a water wheel anology to explain volts, amps, and ohms.

Kanger provides a recommended volts for ohm rating chart with each tank purchase. If you no longer have that, a little formula to use is to take the ohm rating of the coil (2.2 ohm), add the number "2", and the sum will be a good starting spot for voltage to use. Adjust + or - to your personal taste.

2.2 + 2 = 4.2 volts

I hope you are using IMR batteries (Li-Mn) high drain batteries, and not protected ICR (Li-ion) batteries in your mod.

Battery Basics for Mods: IMR or Protected ICR?

Yup i'm using IMR batteries. The Cool Fire is not VV or VW. It just says in the description "a constant output of 8.5W." So how do i know how many volts it's using? The batteries are 3.7 volts. Is that what I go by? If that's the case then I should be using 1.8 coils right? Sorry for the sped questions but I do appreciate all your help.

I'm not 100% sure but I think the CoolFire automatically adjusts the voltage in relation to the resistance of the coil, always putting out 8.5 watts. As it's all automatic the resistance of the coil doesn't matter, you're getting 8.5w whether you're using a 1.8 ohm or a 2.4 ohm coil.

With that particular device, experiment with different coils...1.2ohm through 2.2ohm . Pick the one you like the best. The rule of thumb is "resistance+2" but that doesn't mean it'll be ideal for YOU. Its a good starting point, thats all. Find your own sweet spot. With a VV/ VW device, you can adjust to any standard resistance coil. With the cool fire 1, you have to find the resistance coil that works best for you.

What ken just said is way smarter than what I said.

Ok. Thanks for all your help.

Lol. Thanks guys.
