Former Kayfun - ProVari User's Lower Ohms Questions

[magicmyst]

Former Kayfun 5 & ProVari user here: 1.5Ω - 3.7V - 9W.

Got an Innokin Ares and some other new tanks with some pre-built 1.0Ω coils and decided to try them on a new mod. I'm thinking lowers ohms = lower power, so I'm running a .95Ω coil at 9.5W and getting good flavor. Was watching a Busardo video on the Ares and he recommends 17W for the included 1.0Ω coil. OK, so I tried cranking it up to 15W and wow! More vapor more flavor!

Obviously, I'm out of the loop on vaping electricity 101. I would have expected the higher wattage to burn up my wick. What power range do most people use with a 1Ω coil? I need to get a better grip on this stuff, so feel free to point me to any relevant threads or articles. Thanks!

The lower the 0hms the higher you need to set your power.
Right now the only mtl build i have is the one in my ammit mtl rda (2.5mm. 95 0hm at 20 watts) .

Hope that helps

I'm thinking lowers ohms = lower power...

Actually, lower ohm coils require increased power. Lower resistance wire/coils allows more electricity to reach the coil, so the power demand increases. This is why the first generation regulated mods (Provari = ~10 - 12 watts max?) couldn't fire a sub-ohm coil. By today's standards the first generation regulated mods like the Provari are consideredto have been vastly underpowered.

So folks turned to mechanical mods in order to use sub-ohm. There was no restriction in amp limits of the regulating chip which would deactivate the chip. Wattage output was determined entirely by the battery.

Not so long after that, regulated mods were made with increased wattage output to be able to power sub-ohm coils. Nowadays, some multiple battery regulated mods can allegedly put out over 200 watts.

If you are using home made coils, you can use whatever wattage setting you desire. Suggestions are to begin at a lower wattage setting (around 10 watts) and gradually increase the wattage in small increments until you begin to detect a burnt flavor, or the vapor begins to be too warm for your tastes. At that point, back down 5 - 10 watts until the vape is what you desire.

This is the part that non-scientific minds like mine have difficulty with.

Thanks for the helpful replies, FWIW, here's what I've got running now:

• EHPro Mod 101: Innokin Ares, 26g, 3.0mm, .95Ω, 15W, 3.7V
• Provari V2: Siren V2, 28g, 2.5mm, 1.2Ω, 11.4W, 3.7V
• Provari V2: Savour, 28g, 2.5mm, 1.1Ω, 11.7W, 3.6V

Just ordered a couple Wismec Sinuous P80s, so I'll soon have more flexibility. I didn't realize how much flavor and vapor I was missing with my 1.5Ω, 2.5mm contact coils at 9W on Kayfun 5!

I think some of it depends on the coil, too. I mean, lower resistance coils can handle more wattage, but not all coils are created equal either. I have 1.0 setups that just vape great at the same wattage I'd use on a 1.8 coil, for example.

It is also somewhat to do with robustness of the coil for a general guide you can look at the specs, BUT you also don't have to push it to the max either. IDK.

I get that higher resistance requires more electricity to heat the coil and lower resistance allows electricity to flow more freely through the coil, requiring more watts to maintain the temperature.

I don't get why lower resistance and higher watts = more vapor and flavor. But WOW, does it ever!

Therefor, with a lower resistance wire (thicker), you need MORE power to "fill" it .
So basically you have a thicker wire (larger surface area) and more heat applied to the soaked cotton.
Some people prefer higher resistance because the vape is cooler

Higher watts (higher power output) = more vapor.

A pot of water boiling on a stove with the heat turned up to maximum will produce more water vapor, right? That same pot boiling at a lower temperature will produce less vaper.

More heat does not guarantee more flavor when vaporizing e-liquid. But the denser the vapor (larger volume) often will concentrate the flavor in vapor. There comes a point in "diminishing returns" when increased heat may result in a burnt flavor, which is counterproductive to the results being sought out.
