Voltage VS Watts?

[poolman]

I am not new to vaping, but kinda new to building coils. I used to think lower ohms better performance (clouds). Now that I have a better understanding of how to use steam-engine and the simple idea that mechs hit at nominal battery voltage (3.6-4.2). I think that if I was to build around voltage it may be more efficient (example not having to pump a ridiculous amount of watts). The question I propose to you is if my target is 100 Watts, with that being said is it better to build the atty to .1764 ohms to maximize best performance (flavor & clouds)
without sacrificing battery life?

Thanks out there for your input!
BTW this is for a regulated mod.

If your target is 100 watts, then battery life will always be sacrificed.
low resistance = higher voltage = higher amp draw = 100 watts

The amp draw is the detrimental factor to how long your battery lasts.

I had some advice all ready to go until that last line...

One thing to go through on Steam Engine will be the notes on the battery drain page. Scroll down and there's a good, simple explanation about regulated mods and battery drain. A regulated APV is a totally different beast.

Regulated mod, then the Ohms determine jack diddly squat compared to a mech. On a regulated mod, the only two things Ohms come into play with are 1) the mod reads the ohms, if the Ohms are within the mod's safety parameters, 2) store the ohm reading, check set watts, formulate the volts needed to reach set watts given the reading of the ohms, after that, Ohms make no difference really, they do affect optimal voltage output for a given set watts (example my Sigelei 150watt, the optimal Ohms to reach 150watts is about 0.18 to 0.25ohms, 0.35ohms or higher the mod can't reach 150watts).

Watts Set/Lowest Voltage Available before shutdown or low battery error/90% Mod Control Board Efficiency = Maximum Amps that will be needed.

Yes, adjusting the Ohms to match a certain voltage range to reach a set wattage range should be thought of for efficiency, example again I can get better battery efficiency vs. surface area to get what vapor production I want with say a 0.5ohm 26awg coil at about 50watts max compared to a 0.25ohm 24awg coil at 80watts (the 0.25ohm coil will drain batteries faster due to how much pre-heat time is needed to reach max ramp up in watts).

I can produce a cloud with 100 Watts just like one I can produce with 10 watts. It isn't the tool is it how you use it. Remember a 2 second draw versus an 8 second draw. Or 380°F at 100 Watts versus 65 Watts. Big difference in the amount of time before Temperature Protect.

 

[suprtrkr]

Amen. Regulateds are easy. You want 100 watts? Fine. Set it for 100 watts.

If it's closer to battery voltage it will be somewhat more efficient in its voltage/power conversion. However the difference is largest when efficiency is less important and the opposite of the OP's case, e.g. running a low ohm coil at low power, resulting in low voltage. If going for a higher resistance than on a mech results in thinner coil wire, it will heat up faster and work better (presuming correct all else equal's and ignoring different kinds of wire here).

 

[Grimwald]

I always found the secret to long battery life was thinner wire. Takes lower power and less time to heat up. You sacrifice length of wire so less surface area.

Of course 100 watts would likely cook a 30ga wire in an instant.

To explain it a little differently:
Efficiency. Thinner wire and higher resistance VS thick wire and lower resistance
