Single Vs Dual Coil and tanks?
I'm not to the point of going with a tank yet but thinking down that road eventually. What is the difference in single coil atty and a dua coil atty? Also Tanks have drip tips for dripping juice but also have a tank for holding juice, I think? How does this work?
Ok, first off I've never heard of a dual coil atomizer. Most atomizers don't use a coiled wire but instead, they use a steel mesh.
You may be thinking of dual coil cartomizers that are pre-punched and put into a tank.
A single coil cartomizer is just that...one coil. It will be rated with an ohm ratings like 1.7 or 2.0 or 2.5, etc.
Dual coil cartomizers have two coils running in tandem. These are usually but not always rated at 1.5 ohms. So you have in theory at least, two low resistence coils which produce greater amounts of vapor and obviously go through more juice.
If you plan to run dual coils, I would only advise you to do so if you already have a variable volt device or a higher volt fixed device. Standard 3.7 volt vape set ups just aren't powerful enough to run a dual coil to its real potential, because those two 1.5 coils really just equal a 3.0ohm resistance. Something like an ego battery (non twis) can't keep up. You need to hit a dual coil with higher voltage.
Also, if you are using a kick in a tube mod you will be disappointed with dual coils. This is because the kick will read the dual coils as a single 1.5ohm and adjust you voltage accordingly to get the desired wattage.
Thank you, that did clear up the dual and single coil issue quite a bit for me. What is a "kick in a tube mod" ?
I use 1.5 ohm dual coil tank cartomizers. They provide a warmer vape without burning the eliquid. I agree you should only use them with a PV that has a strong enough battery to handle them. A straight 3.7 volt PV just won't cut it.
I don't have a Kick but do use a Darwin which the kick is based off of. I have absolutely no problem using regular dual coil cartomizers or tank dual coil cartomizers with the Darwin. At 12.2 watts using the 1.5 ohm dual coils, they adjust to 4.4 volts and provide nice warm consistent vapor. And even being a heavy vaper, I still get 18+ hours on a charge.
A kick is a small electronic chip type device that turns any tube mod into a variable wattage device. This is different from a variable voltage device.
What you do with a kick is, figure out what your wattage sweet spot is. Say it's 7.5 watts for example. You adjust the kick to 7.5 watts and insert it into the mod, screw it all back together. Now regardless of what type of atomizer, carto etc that you put on there you are going to get 7.5 watts. If you put a 3 ohm on there, the kick will sense that and adjust voltage to give you 7.5 watts. If you put a 2.0 ohm there, same thing, it adjusts voltage to give you 7.5 watts.
The problem comes in when you have dual coils because the kick is fooled. Instead of reading a dual coil at the combined resistance of 3.0 ohms, its reading the whole thing at 1.5ohm and is making its voltage adjustments based on that instead of the true 3.0 ohm resistance.
If you tell me your set up, I can give you some options that would probably work for you.
yeah i was wondering about that...if you could just push the wattage way up to work around...i've never tried it myself

I think dual coils really become popular because they allowed a much warmer vape from an unregulated device like a simple one-battery mod. I have had some bad luck with dual coils burning out quickly or being doa, so I stick with the single coils.
It sounds like you are thinking about a cartomizer tank like the Dual Coil Tank (DCT) Smok Tech. They typically are shipped with dual coils, but you can easily swap them out with single coil replacements. Depending on your device, you will probably want to try a variety of resistances to see what suits you best.
Just wanted to clear some things up. You said "Dual coil cartomizers have two coils running in tandem", this is not accurate, dual coils have two coils that are run in parallel, not series, there is a big difference in the two.

A 1.5 ohm dual coil is two 3 ohm coils run in parallel, if you know electrical theory, this means the effective resistance is half ie, 1.5 ohms.
Now it is true that a dual coil will produce more vapor, this is because with two coils you have twice the surface area to vaporize the e liquid.
You did get this right, "This is because the kick will read the dual coils as a single 1.5ohm and adjust you voltage accordingly to get the desired wattage."
I'm not trying to be confrontational, just trying to explain how dual coil carts work.

Correct. DC carto's are wired in parallel, not series. They're typically 3 Ohm each, which in parallel presents a 1.5 Ohm load to the device.
