I perfer a single coil

[Rocketpunk]

And that's the problem. Right there.

Dual coils can be tricky.

A 1.8Ω dual coil atty consists of two 3.6Ω coils. But your battery reads the combined resistance of the atty--it doesn't know that there are two coils joined on the same circuit. That's why you need to know what the resistance of each coil is and tell your battery to supply more wattage than you would need to supply to a single coil of the same resistance. A 1.8Ω single coil atomizer will run much hotter than your 1.8Ω dual coil atty, which splits the load between two 3.6Ω coils (thus producing a cooler but more voluminous--due to increased surface area--vape).

The main reason DC cartomizers were invented in the first place was to decrease the heat of the coils to prevent burning of filler in cartomizers (the first dual coils were used in cartomizers).

It will also increase the demand for amps the battery needs to supply and decrease the overall heat (power) of each coil, thus requiring higher voltages.

This is how I see it. Let's say I like to vape at 6 watts (on a single coil). If I tell my PV to supply 6 watts to two coils, my atomizer will not vape the same as it would if it only had to apply 6 watts to one coil--a single coil would be working at 6 watts, two coils--at 3 watts each, more or less. In theory, at least.

In the real world, the realized, true experience would be probably somewhere between the two wattage figures--when using a dual coil device.

In my own experience, I can't put a 1.8Ω single coil stock cartomizer much above 4 volts (8.9W) and enjoy the vape--it's too hot and harsh for me. The highest I can comfortably go with a single-coil 1.8Ω atty is maybe 3.6 volts or so (7.2 watts). However, I have absolutely no problem vaping a 1.8Ω DCC at 4.0v and up and I have no issues with dry hits or burnt taste whatsoever.

Imagine vaping two 3.6Ω atties attached to the same battery at the same time. The battery will have to work much harder and will drain much faster than it would with just one 3.6Ω atty, right? That's why dual coils mow through your battery--and your juice--like crazy.

^^^^^ This.

Heya Rocketpunk! Long time.

And thanks.

You explained that far better than I could have hoped to...thanks ^_^
Remember those cartos were the bees knees back in the day. Real popular, though I was too busy trying to rig up a perfect autodrip mod at the time to buy some of em and experiment. Nice post Katya.

I have a single coil all glass FAA tank which works great, I also use H2 tanks a lot and those work really good for me with lots of vapor and flavor, and they use inexpensive replacement coils. I wanted to try another all glass tank with a duel coil but it just doesn't produce what I expected. My H2 tanks work much better.

What's an FAA?

And that's the problem. Right there.

They sure were...
