Why Sub ohm regulated vape?

[Lilvapie]

The coil head is usually just called a coil
head, although nowadays that one resembles cartomizers a lot, which isn't a surprise.

clearomizer comes from clear and cartomizer.
But cartomizer is usually used for a disposable carto system where the thing you call a carto is tossed when used up.

"tank" is used to distinguish a reuseable system; the tank is reused, but the coil is used and replaced in the tank.

O that explains everything.....

The Atlantis& nautilus BVC heads may resemble a miniature punched carto. but thet aren't cartomizers.

Carto's are a complete single piece unit ready to vape after filling, direct to power source threading on one end, vapor out of the other.
They provide an option of using them by themselves/stand alone or with holes in the tube then used inside a tank.
They have many times the amount of wicking material surrounding the coil compared to any clearo head and are made in different sizes from mini/halfling to XL, a few proprietary carto's hold up to 3 mls.

Clearo heads are just one of the pieces of a multiple piece assembly that together make a vapable unit.

There are two main variables with coil design, surface area and mass. Air flow in the atty is also a key contributor to the way they will vape, but let's assume that is appropriate for the power. You can make a 0.25 ohm coil with the same surface area as a 2 ohm coil (different wire gauge is required) and run both successfully at 50 watts. You can design both coils to have more or less surface area. The 2 ohm coil will however have less mass which means it will heat up and cool down faster which is good. Both coils will apply the same watts per square inch so the vape will be very similar all other things being equal.

A lot of people don't know this yet. Old habits die hard so it will take a while

Interesting. Thanks for feedback. And sharing of Steam Engine.

It's not as "correct" as you seem to think it is. Coil resistance in a variable wattage, regulated mod like the Sigelei 100, for example, has no bearing on battery current drain. Coil resistance only dictates the output voltage.

Notice the amp draw (battery drain - current) doesn't change in the examples below (.5ohm coil and 1.0ohm coil) but the output voltage does. The second example also shows that a 1ohm build cannot be run at 100W due to the mod's voltage limitations. Additionally, current drain increases as battery voltage decreases. This can be modeled in the calculator by clicking the the down arrow next to the battery voltage and watching the current drain value increase.

I've been ignorant to this fact until now. Always viewed amp load by the atomizer alone. Obviously the boosted power has to come from somewhere...the Bat! And with an overhead of loss. Thanks for clearing that up.
