28 gauge vs 32 gauge. Winner is 32 gauge (for me).

I understand 28 gauge is more durable, like a Buick compared to a Ford Mustang maybe, but I really like the 32 gauge's crispness and flavor. My first build with 32 gauge and it was a bit tricky compared to 28 gauge, but the result was worth it.

I prefer 24 gauge, more like an F350 pickup

I'm glad you found something that works for you, if we all liked the same things it would be a pretty boring world.

32ga heats up quickly and works well. The reason I use 28ga is for the durability. I can wind one coil and re-wick it for a couple of months easily. If I were more gentle when I reposition it and align it during a rewick, there's no telling how long it would last. I break 32ga early on.

Without a power source output value or build details... your comments don't provide a useful frame of reference, nocig.

If you have a low current output device... then yes, you probably don't have enough current to adequately heat 28 gauge wire.

For a given output, say 11 watts, and a resistance of around 2.0Ω... 32 gauge has a nice warm heat flux of 392 mW/mm², while 28 gauge has a stone cold heat flux of 98 mW/mm² ("heat flux" is a measurement of radiant heat in milliwatts per square millimeter).

To obtain a heat flux, at the same example resistance, similar to 32 gauge at 11 watts... you'd need 45 watts, for a 399 mW/mm² heat value.

State O' Flux: I see I have a lot more to learn.

Sorry, here is a bit more information: KFL+, 1.57 Ohm on a mech mod with a 2500 mAh, 20 amp LG IMR battery. Single coil wrapped with a 3.xx mm screwdriver.

The flavor I get beats all 28 gauge builds I have made, and I get a nice citrus aftertaste I haven't sensed before. vaping Burley e-liquid, 24 mg/ml from Inaweraflavours.

This is actually easier to calculate with a regulated PV vs. a mech mod... because a mech will provide a current output of what ever the resistance demands, within the continuous current discharge rating (and pulse or momentary discharge as well - if you exceed the CCD) of the battery as opposed to a user controllable, fixed wattage output.

Using standard Ohm's Law formulas, the battery you're currently using has a potential peak output of 84 watts (4.2v/20a)... this is assuming zero voltage drop, which isn't all that likely. Of the potential 84, you're using about 11 watts with a 1.57Ω build.

An educated guess is... the difference that you're noticing is the difference in heat flux and heat capacity (click my sigline hyperlink for "Steam Engine"... a coil modelling program created by one of your Norwegian countryman - 'Dampmaskin') between the 28 and 32 gauge wire.

Building both your coil models - and bearing in mind that your mech mod has far more surplus current "headroom" for your 32 gauge build than your 28 gauge build - it would indicate a marked preference for the (much) warmer and faster heating build.

I've adjusted coil gauge (and net resistance) with mech mods to obtain a particular flavor from a particular juice... and your 'discovery' is likely representative of a preference with the particular juice in question.

In closing... I see unregulated mod vaping as an "ongoing experiment", and although there are some basic rules, there are no rules to a personal preference other than a individuals safety, so... if it makes you happy, then it's all good. ;-)

Thank you. Very interesting to read. Can't reply much, as this is new to me, but I understand that the setup I have now gives my battery much headroom > great vape.

I find the same thing with different gauges of wire. 30/32g seem to pick up more notes than a large 24g wire for sure. What I find is sweeter/fruitier juices tend to taste better on smaller wire where rich/creamy juices react better to 24/26g. It is abviously a matter to opinion or preference but what makes me think it is more true than false is more and more builders are mixing >32g with their <24g wire to try and bring out the most of juices.

I find the 28 easier to work with but I use to rebuild evods and ProTanks with 32 and loved it. Sure is a lot less expensive to do you own and it is instant gratification when it works.

Good luck to you and have fun.

I just got through replacing a coil on my Kayfun 3.1 that I've been vaping on the Provari and the iStick since about Thanksgiving. It was starting to give me crummy vapes with low output and no flavor, even with regular dry burns and new wicks. I intended to end up at 2.5 or 3 ohms to give my iStick some headroom when the battery is at full charge. I ended up with 8 turns/ 28ga /3mm and 1.9 ohms. Since I had to be somewhere soon I took it and ran with it. I've been winding 2 ohm coils for the Provari for a long time before I got the iStick and I guess 8 turns is imprinted on my brain ...

I had forgotten how efficient a new coil can be. I went from wimpy vapor to clouds . I guess I need to wind a new coil every month to 6 weeks regardless.
