high ohm single coils

[dirty_luck]

Just a thought ive been having lately and I cant find an answer for the life of me.

Everyone talks about sub ohming and going lower and lower on the ohms. Not my cup of tea. Yes i can wrap the coils that low i just have no desire to do so. But what about higher ohm vaping. Instead of dual coils running at 1.5 ohm on a rda what about wrapping a single coil at like 3.5 or 4 ohm range using28 or 30 ga wire to give more surface area than a standard single coil at 1.5 ohm or even 2 ohm? Any advantage or disadvantage to running say a 3.5 ohm micro or nano coil? Any dangers to be aware of?

Thank you for that question, I have wondered the same.

 

[dirty_luck]

Bump? Seems like we may just have to try it strider lol and see what happens

Just checked mine that I'm vaping on right now: it's showing 2.7 ohm.
Thought it was over 3 ohm?!!! Well maybe somewhere inside is touching; when it gets knocked around sometimes the ohms changes;

ah; screwed it off then back on again;
read 3.5 ohm,
unscrew/screw: 4.2 ohm
one more time: it's at 4.2 ohm at the moment.
when the protank head presses down on the positive center pin, these new clear silicone grommets the heads have been coming with are pretty soft and springy, so they introduce an additional movement/distortion causing the coil wire to distort or shift and causing a short somewhere inside the atomizer

right now it's gone back to 2.7 ohms.

anyway I was going to say sometimes it seems as though the higher ohm coil takes a bit longer to fireup; if you're chainvaping it might not even be noticeable, but if you only take a short occassional puff it helps to fire up a couple seconds first before vape.

I know what you mean about the latest kanger heads. Hit and miss. I started recoiling my own for the protanks. Easy and good results with cotton.

I agree the higher ohm does take a few milli secs longer to heat up.

About these new heads with the soft silicone grommets, the material is actually easier to work with! Plus there's the springiness factor which perhaps was intended to help with the common battery center pin getting pressed too hard problem. My primary reservation is whether they are an improvement or a step backward with respect to heat sensitivity compared to the earlier white/cream bakelite harder material that was being used. Because the coil wire gets hot and compresses directly on the grommet.

All that's old is new again. High ohm vaping was the latest fad about 3 1/2 years ago when 5v vaping was all the rage. That was in the days when the Buzz was about the only VV device on the market but 5v and 6v mods were relatively common and inexpensive. There's nothing wrong with putting more coil into contact with your juice. As noted though it can take longer for the coil to heat up. But yes, there is more surface area with which to vaporize your juice. Plus, it's a heck of a lot safer going that direction than to go so low on your ohm's that you're reaching the limit of battery technology.

If you hit it with enough power you'll get good vapor production, but it will be a cooler vape than if you were using a lower Ω coil. Heat up time is usually a little longer too, and you'll find yourself taking longer puffs. Watch some of the older YouTube vids and you'll see the 10 second draws. It's a good vape if you like flavorful and cool.

I personally build around 2 - 2.5 ohms. I think that higher is just causing the battery and switch to work a little harder. That long warm up time is not cool in my book. That being said if youre doing a long vape session, the whole atty will warm up too, so after a while it won't take that long to heat up and give you soem vapor.

In the Sigelei v3 thread, I was asking questions about batteries, general stuff since I have very little understanding of ohms/volts/watts/amps, what they all do and mean and such. The nugget I got from that discussion was that a higher ohm coil saves battery life, because it "doesn't draw so many amps." As I said, most of those terms mean exactly diddly to me, but "longer battery life" I grok very well.

To be more precise, and more simply put, just using lower watts on your sigelei v3 will mean longer battery life

The main reason I wanted a DNA30 was to use standard resistances at the same power outputs I get with deciohm coils...but I think I'm over it now.. If a hana becomes available when I can justify getting it, I will, but meh.

This is one of the great advantages of a high-voltage regulated device -- you can build a big, high-resistance coil and fire it at full power. This allows you to do many different things, at the baseline you can make a highly responsive, high-power setup.

Perhaps, but then it won't vape as I want it to. I need anywhere from 8.5w to 10w to get the TH I want. I'm already at 85% PG and can't go higher than 9mg, so heat is the only option I have left.

If you have a mod that will deliver higher voltages, a 3 or 4 ohm coil works rather well. You'll draw more amps to allow the 3.7 volt battery to provide 5 or 6 volts, so the "length of time the charge on the battery lasts" is pretty much a wash. No such thing as a free lunch...

I don't know what the voltage is; I started getting such an assortment of Ω in my coils and cartos, I started using the vw instead to save time and brain cells.

VV or VW doesn't matter, just boost it up enough so it tastes good, no burnt, and hot enough....then check the numbers so you know where to set it next time....

After I'm tired of my high-nic/low-TH blend in the morning, I start it at 7.5... thru the day it rises to 9.5 to keep providing throat hit, I kinda go numb to it after a while. I've determined that I can go to 10w and still not get a burnt taste, so I've done that a few times, but mostly stay at about 9-9.5w.

Actually I have to make a correction.

The higher ohm coils give you more efficiency in the use of power, so
For the same watts
the higher ohm coil should vaporize more liquid than the lower ohm coil.
hence a longer battery life.

I'm just thinking of how many wraps it would take to get 3.5 - 4 ohms with 28g wire. Yeow. It would look like a slinky.
