I am looking to buy a Kanger IPOW v2 1600mAh. I believe it goes up to 15 watts (advertised). I have never used a VV or VW device. I have a bunch of coil heads some are 1.8 ohm and some are 2.2 ohm. Does the resistance level matter with a device that is strictly variable wattage? I assume the voltage will automatically increase or decrease with changing the wattage? I am just wondering it simply being able to adjust wattage will be better to vape from if the voltage will automatically zero out anyway, and if my coil heads make a difference? I am real to to the idea of variable voltage and watts... appreciate any info!!!

Hi,

I'm kind of new to all this, but didn't want you to not have some type of answer. My husband uses a kanger pro 3 tank (with kanger coils too), with an eleaf istick. (I also have an istick but not settled on a tank yet). The istick goes up to 20w. Yes, if you increase/decrease the wattage the volts will change automatically and vise versa. I am not sure about the coil heads question if it makes a difference or not. He did say getting the eleaf compared to the ego he did have made things much better tasting and he likes adjusting it to the level that taste best for him. Hope this helps you some and someone else can explain more in detail for you.

The resistance DOES matter, in that
a) As you increase watts, you could hit a LIMIT if your resistance is high...
b) Surprisingly, 10 watts on a 1.5 ohm coil IS a little different than 10 watts on a 3 ohm coil. The higher resistance one won't heat up as fast - at least that's my theory - but I could tell the difference, and prefer the lower ones.

But you WILL be able to use both of the ones you have.

Hope that makes a little sense...

To elaborate a bit on Train's comment, no and yes.

The values you've stated, 1.8 and 2.2, are close enough that you probably won't notice a difference. 1.5 vs 3, I too think you'd notice, for the reason stated. I find the same when making equal resistance coils with, say, 28 and 30 for my RTAs. The 28, being a much bigger diameter wire, needs a lot more turns, has a lot more mass, and takes a lot longer to heat - and cool.

A variable watt device will, as you surmise, automatically adjust the volts to hit the watts you've set - within its operating range. Too high a resistance, and it won't be able to get there. But it shouldn't hit that with what you've listed as having.
