I have been vaping for a while, there are tow many different coils in the market right now. One single tank may have 10 different coils can fit in, some of them have different ohms. Does the ting difference between ohms really matter?
:(
Lower ohms equals quick ramp up and warmer vape.
Higher ohms equals slower ramp up and cooler vape.

Some like high power on low ohms. Some like high power on high ohms.

Some like low power on both.

It really comes down to personal preference and finding your sweet spot.

That's the beauty of vaping. You can dial in your vape exactly how you like it.

Different combinations of ohms and power create more flavorful vapes. Other combinations create more voluminous vapor. Juice types have huge impact as well.

So yes, ohms and power make a huge difference in your overall vaping experience. Try all the combinations and let us know where you land!

Happy vaping in your search for the perfect vape[emoji134]

Only if you are using one gauge of wire.

A 3 ohm 32 gauge coil at 30W will heat a lot faster than a 0.3 ohm 22 gauge coil at 30W

Yes, it does.
Put it simply some are for lugnhits of massive clouds, others for mouth-to-lugn-hits.
It depends which one you prefer.
Also to make things more complicated there are also TC-coils for temperature control mods.

why make things so complicated:( vaping should be a nice easy thing.

Because people have varying tastes, preferences and not one size fits all. It's been a while since I used premade coils but it would be nice if they sold them in a multipack with different coils ranges so a new user could buy one and figure out what they like (maybe they do, I don't know). Start with some 1.2 ohm coils and go up or down from there.

If you m2l then a above ohm 1.0 and above is what you need

If you lung inhale then below ohm (sub ohm) is your answer .09 and below

What tank you using?

.9 please don't go to .09...

But yes, I found sub ohms are good for me because of the lung inhale.

coils depend on preference and what you are looking to get out of your vape bigger clouds and highter temp require lower ohms better battery life and you may want to look for higher ohms and single coil its kinda like a car if you have kids a Ferrari may not be the best choice when a honda minivan will fit everyone comfortably

In general...

Lower Ohm Coils Will:

  • Heat The Coil Faster
  • Produce More Vapor
  • Drain The Battery Faster
  • Use E-Juice Faster
  • Produce A "Warmer" Tasting Vape
Higher Ohm Coils Will:
  • Heat The Coil Slower
  • Produce Less Vapor
  • Provide A “Cooler” Tasting Vape
  • Use Less E-Juice
  • Prolong Battery Life

It is easy. Unfortunately most US citizens never learned basic electrical theory in physics; ohm's law is the most basic electrical treory you can learn, and a mech is literally the example circuit diagram everyone learns first... a power source, a light bulb, and a switch.

If you m2l then a above ohm 1.0 and above is what you need

If you lung inhale then below ohm (sub ohm) is your answer .09 and below

As others have mentioned, this had better be a typo. This isn't the sort of thread to be throwing this sort of misinformation.


In response to the OP's question:
The ohm rating of your coil matters for two reasons:
On a mech it determines the overall wattage of your vape.
With a regulated device it isn't as important as long as you are in the working resistance range for your mod. As an example, the dc-dc converter circuits in vw devices will have a max operating voltage as well as max operating watts. If you have an atomizer built to the very top of your mods resistance range you might run out of volts before your mods total watts possible output has been achieved.

Having a lower resistance coil setup doesn't always mean faster rampup and cooldown. If you are building on a mech and using a lower gauge dual coil your overall coil mass can easily end up very high for the overall watts being generated (I.e. something like a 20guage kanthal dual coil at .3 ohms; sure you are pretty strongly in subohm territory, but the coil is going to react very slowly due to the mass).
The most important things to consider are
A: final wattage
B: the overall mass of your coil
These two factors combined = heat flux, which is probably the most important value to consider when you are building a coil.

It has been my experience that in a rudimentary practical sense the resistance does more to shorten or lengthen the draw than anything else. If the draw is too long and the power settings don't change it, then the resistance is too high for me. If the draw is too short or the end of the drag seems harsh and the power settings don't fix it, then the resistance is too low for me.

very helpful, thank you.
