Will a higher ohm coil last longer than a lower ohm coil?

[Flt Simulation]

Just curious if a 2.5 ohm coil will last longer than a 1.8 ohm coil in the same brand and type clearomizer.

I would think that even though the higher ohm 2.5 coil will normally require a higher operating voltage from the adjustable battery, the 2.5 ohm coil is also thicker (heavier) than the 1.8 ohm coil, so it might last longer (using the same vape liquid)

What ya think ...

50 years as an electronics tech...I think so - with everything else being equal.

I don't know the technical reason behind it, but yes, the higher ohm coils DO last slightly longer than the lower ohm coils.

The 0.8Ω, 8 wraps of 27 AWG Kanthal, micro coil in my daily driver REO will be 6 months old Saturday. For the same material and form factor (i.e. round), lower resistance wire is thicker (like delivering water from a fire hose rather than a garden hose).

I haven't noticed any difference in longevity vaping at either 3.3 or 3.7 volts.

Usually a lower ohm coil will have a thicker wire, or just less wraps.

But typically, a higher ohm coil will last a bit longer, but it's nothing to do with the material itself (thicker wire, etc). It's just because the lower the ohms, the hotter it burns, and the hotter it burns, the faster sugar and such gunk forms on the coil. If you're able to, dry burning brings it back to life for a little while.

If I understand it right, the higher ohm wire could have more problems and may last "shorter" because it is thinner, hence it has more resistance. It is more susceptible and sensitive to poping (hot spotting), defects and rough handling.

"everything else being equal" is the big question here ... Since there is larger diameter coil in the 2.5ohm, it will certainly last longer than the 1.8ohm .... but if your needing to feed the 2.5ohm coil with more voltage (so it equals the same amount of vapor as the 1.8ohm coil), then maybe it really won't last any longer after all?

ok ... I got it backwards ... I was thinking that a higher ohm 2.5 coil would have a larger diameter wire than a low ohm 1.8 coil

If you're able to, dry burning brings it back to life for a little while.

Or a LONG while if you have the option to use cotton wicks and change them out when you do. Wickless dry burns keep em going for months. Worst you will get is some moderate to heavy oxidation which has little/no impact on your vape.

28GA 1.3Ω Nano, 14 wraps @ 3/64" kickin it strong at 3 months old.

Not exactly. thickness and length effect resistance.
Most Low Ohm vapors use thicker28-30ga wire as opposed to Clearos 33-36ga.
Last longer entails several factors:
E-liquid content - Dyes/coloring, sweeteners, amount of Flavoring, pg/vg content, etc.
Coil build quality - proper wrap contact to wick, coil spacing, coil to device attachment
Liquid Flow - Liquid helps to cool as it is passed to the coil relieving heat buildup
Air Flow - Better Air flow pulls heat away from coil faster

More goes on in vaping than we ever think about.

Are you talking about the wire gauge when you say coil diameter? Or the actual diameter of the coil?

Same wire-higher resistance lasts longer. Current is the heat creating factor in electricity.

 

[NicoHolic]

Just knowing the ohms doesn't tell you anything else about the coils. They could have the same gauge wire and coil diameter with the higher resistance having more wraps. Or they could have the same gauge wire and coil diameter with the higher resistance having a larger diameter coil. Or they could have the same coil diameter and number of wraps with the higher resistance using thinner wire. And so on...

Let me rephrase my question.

Some companies offer the same coil in various ohm ratings. Which would you pick? ... the 1.8ohm coil or the 2.5ohm coil as long as you were using an adjustable voltage battery? (coils from the same company)

Understanding that in order to get the same amount of vapor from each of these coils, it requires you to set your battery to 3.5v when using the 1.8ohm coil and setting your battery to 4.0v while using the 2.5ohm coil.

Hard for me to fathom how some people pop them or burn them out so quick. I tend to rebuild them just because I can't get it through my head that they last as long as they do with only a change of cotton and a dry burn now and then. Like crxess says, so many variables.

Just to add to the data, have not noticed much of a practical difference in longevity of standard ohm ranges. Like I say, they all seem to last forever until the OCD kicks in and I start rebuilding for the sake of rubuilding.

I have been using coils in the 1.8-2.5 ohm range for almost 18 months. Honestly I have seen no difference in performance or length of life when used and maintained properly and on a VV/VW device.
Generally I use the higher only on the adjustable and use lower ohm on my standard batteries and Mech Mods to maintain a decent Vape.
When ever I recoil a head, I do so in the 1.5-1.8Ohm range so they are usable on both devices.
Wick is more critical in most Clearo style devices than coil resistance. To much wick and you dead out of the gate. To little and it can be flood city.

If you're talking clearomizer heads, particularly Kanger, I bought 1.8Ω (which usually read higher) for the Vapeaggedon flexibility. They'll work on just about any battery. The 2.5Ω are too weak on a mech, and especially on a 3.3V regulated battery.

That's exactly what I'm talking about. I have a Kanger T2 Clearomizer. I can buy coils the are 1.7-1.9ohm, 2.2-2.4ohm or 2.4-2.6ohm

Since I use a Vision Spinner VV eGo Battery, the output power is adjustable between 3.2 - 4.8v, so it can power any of these 3 different ohm coils.

Just wondering which coil might be best to use, or last the longest putting out the same amount of vapor.

Thicker wire has less resistance, so at the same wire length the 1.8 ohm coil will have thicker wire. Think of it like this: the wire is a hose. A larger diameter hose offers less resistance to the water (current) passing through it => in a coil, less ohms/inch. Ohms add up the longer the water/current needs to flow.

I've never popped a coil in normal use. Did it once when I accidentally fired a dry, wickless coil at 15 watts (was going to dry burn but had forgotten to set my SVD to 3.5 volts).
