Best Coil Build for Mech ?

[EdT586]

So is there a secret combination that would make the best single coil build for a mech mod with the best 18650 battery ?

- Longest battery use
- Hottest coil
- Most durable/longevity

So what gauge wire, ohm, and coil diameter ?

 

[PaulBHC]

The higher the ohm number, the lower the amp draw on the battery and the faster the coil heats up.

The higher the gauge number, the thinner the wire gets, and the ohm number goes up. 32 and higher is used in coil heads where you don't have room.

Lower gauge numbers are thicker and give more surface area.

I use 30 gauge kanthal on a 5/64 drill which gives me around 2 ohms. At 4.2 volts that is around 8 watts and 2 amps.

Use the tabs on this calculator to see how all of this works together

IMHO, 24 gauge Kanthal, six wraps,.5 ohms, 2.5 mm diameter - but that's just me.

Thanks for your input, I came to the same conclusion except it was on 28AWG wire. I need to get some 30AWG Kanthal now !

On a mech mod ? even 26AWG is too much !

 

[PaulBHC]

Kanthal is cheap enough to experiment with different gauges.

I use genesis toppers with rayon wicks and 25pg/75vg liquid. coils last for months, wicks for weeks (just because it is easier to toss one out and rewick for a dry burn), and a battery lasts all day or longer with regulated devices.

My wife uses an 18350 mech and Innokin Coolfire I that is set at 8.5 watts. Looking at the Coolfire designed for use with a 2 ohm i30 topper is what inspired me to use 2 ohm coils at 8 watts in my gennies. Works well for me.

 

[EdT586]

Yup, getting the best out of all those factors is want I wanted. I don't want to be taking everything apart and making coils every few days or charging my batteries everyday.

honestly, i feel like that's what we have to do in the beginning to figure out what our favorite setup is. it is very subjective. in my trident, 28g/30g microcoils work great.

- Longest battery use
are you using a mech or regulated? lower wattage and higher ohms will generally provide a greater battery life
- Hottest coil
depends on your airflow
- Most durable/longevity
that is dependent on how often you rewick. if you slack off on rewicking, coils will get worse faster. if you rewick more frequently, you can get an impressive lifespan on them.

In mech mods. I guess it makes sense with the rewicking as the juice will keep the coils from overheating and eventually melt away.

Don't know, because the mod is not where you build the coil.. As said above the power and juice consumption is determined by the ATOMIZER.. the mod, at least if a mech, is just the storage container/conductor for the battery and switch. Power and juice usage is regulated buy the AMOUNT OF METAL USED TO CONSTUCT THE COIL, in your atty.

What camp do we call ourselves if what to use high resistance and low power in vaping ?

In HiFi amps we can ourselves the low power, high efficiency crowd, the rest of the world has moved onto high power amps and small low efficiency speakers because the marketing gurus think that larger numbers equates to more power and profits !

 

[MattyTny]

If you're set on single coils and don't mind trying something different you could try a single parallel with 28 gauge. I would use a diameter around 3mm and shoot for a resistance of around 0.7. You could also try smaller chamber atomizers to increase temperature and vapor density. If you're comfortable with single higher resistance coils above 1ohm there's no rush to switch. If you do just do it in small increments.

What batteries will you be using? Are you using an ohm meter?

Someone could move this to mechanical mods or RDA/RTA.

28AWG is the largest I would use with a mech. Going sub ohm is not good for battery life and that is a no as well even though I am using a 25R battery that is capable of sub ohm.

I don't understand why the vaping world likes a warm vapor, we cigar smokers strive for a cool smoke as the epitome of a fine cigar that was made by a master roller with 20+ years of experience. So a warm vap would never be one of my criteria as it would be considered an expensive dud ! ...LoL

I don't understand this facination with hot vapes either. 28 is also the largest I will use on my mech.. Not because of sub ohm and high temperature though. Fatter wire would in produce cooler vapes, if you didn't also increase the POWER being fed to the coil. My problem is that 28awg is the SLOWEST gauge I want without the ability to BOOST the voltage. I would love to be able to get the flavor from a big fat coil. I just don't like wasting so much battery getting the coil up to temp. I like my 5 second firings to be 5 seconds of sucking not 3 seconds of RAMP and 2 of puff.

Reminds me of the Stereo dad had when I was a Kid. He still uses the speaker cabinets today in his house, built in 1970 as church organ speakers. As currently set-up those 2 speakers can drown out my Brothers 500watt car system, while being fed less than 50 watts. As Kids my brothers used to take naps INSIDE the boxes.

You can get your hands on some 29AWG and play with coil diameter size 2mm, 2.5mm or even 3mm.

50 watts is a lot ...LoL, audiophile grade tube amp rarely go more than 15W RMS. so it is 7.5w/channel or less !

I understand where you are coming from. We all have different tastes and the equipment gives us the ability to vape how we like.

I also think there is a misconception about sub-ohm due to it being popular with really low builds. Using high amperage batteries are great for low builds, but when you generalize sub ohm with pushing a lot of amps things start to get a little muddy. Anyway you cut it, you are always going to use a portion of battery current. Although something like 0.7ohms is considered below 1ohm, it's really not pushing a lot of current on a mechanical, maybe 5-6 amps on a charged battery. Take a 1.2ohm and it's pushing about 3.5 amps. Both those builds are well within the safe range for a mechanical.

I'm not trying to push an opinion, I'm just trying to clear up some misconception about sub ohm. I use resistances below and above 1ohm, I like variety.

That being said, you can pair a non sub ohm coil with a reduced chamber atomizer and get a nice dense slightly warm vape. Or a more airy or bigger chamber atomizer and get a cooler or airy vape. I used to use a 1.8ohm coil in an RDA on my MVP2 at 11 watts.

I know.. I said less than 50watts, too avoid BS claims if I said at 5watts or less. He's no techy, just likes good sound. And they were built and designed in 1969-1970.
Dads speaker boxes are like those big black ones, just a bit smaller, 36" cubes. He built them to use at church pikniks and such. But I swear they are about the best things I have ever heard at low volumes, even in a big room. (not that I am any kind of expert)
