ohms and wattage question.

[joshonemoore]

Is wattage output a universal performance metric regardless of resistance? i.e. would xW with higher resistance because of and therefore more coil surface area, perform the same in experience (throat hit/vape production) as a lower resistance (less surface area) pushing the same wattage. Or is the additional heat of the low resistance going to have an effect. i wonder as it pertains to whatever optimal performance vs. battery life ohm level may be. or is it pretty much negligible and I am way over thinking this.

You wattage is your "heat". How much heat depends on how much surface area you have. You're waaaay over thinking it. Hitting low resistance to boost wattage is what the mech guys do, on a VW device, build a coil that fits in your atty and that wicks well, set your wattage, and vape away,

thanks, probably a little OCD getting things dialed in. Ironically I have opted for the simple but powerful battery in products with vv/vw. I just purchased a 5ow 4400mah eleafand i seem to prefer vaping at between 15-18W, so im pretty sure im good. in fact, while im thinking about it, why would one vape at 50+Watts? wouldnt that burn the juice?

Vapers have different preferences. Some like a cool vape, some like a warmer vape.

A knowledgeable and experienced coil builder can run a sub ohm setup pushing over 50 watts and it can taste as smooth, flavorful, and cool as a Tootle Puffer's setup using standard resistance coils and 10 watts of power. The main difference is in the amount of vapor production and juice consumption.

That he said. I run 45ish on my tanks, 75ish on my drippers.

Wattage is energy per second.
Energy is required to evaporate liquid.
Twice as much energy is required to evaporate twice as much liquid.

As it pertains to battery life: a battery contains a certain amount of energy.
The amount of energy contained in the battery can evaporate a certain amount of liquid and no more.
Wattage is how fast you use up that energy.
Higher wattage means you are using up your battery life faster.

i understands higher energy use will spend battery life faster, what im curious about and didnt state in these terms before, is the difference between xW on a single coil vs xW on a dual or triple coil. it stands to reason that xW is xW regardless of the amount of coil used. is it about atomizer(coil) life? or is it performance related?

 

[Dampmaskin]

The amount of vapor is determined by the power (watts). (Plus airflow, juice, wicking, atty chamber size & shape, ambient air pressure, temperature, humidity, etc.)

The flavor is determined by the heat flux (power divided by surface area of coil). (Plus airflow, juice, wicking, atty chamber size & shape, ambient air pressure, temperature, humidity, mental state/mood, what you've been eating/drinking/vaping lately, etc. etc. etc.)

So for the optimal battery life, with heat flux being constant, I think this can be summed up like this: A smaller coil require less power, and produces less vapor. Then it's up to you to determine how much is enough to get the experience you want.

1:
10 watts on a single coil should evaporate the same amount of liquid as 10 watts on a dual or triple coil.

2:
One difference between a single coil compared to a dual or triple coil, might be the surface area.
