i use a aero mega tank they are using 1.8 atomizers ... the leg has the thing beside it which im sure is the resistance is 2.0 is that bad im confused at what this means do i monitor that or what
New coil heads can vary in resistance +/- 0.2 ohms, which is normal. You can expect the resistance to increase over time due to the wire aging and the accumulation of e-liquid gunk on the coils.

is the goal of that reading meaing i dont need to go over 1.8 or what im just so lost on how this works im use to these twist batteries the cheap ones im trying to stay within a safe range

Not sure what your question is. o_O

Resistance (the coil's ohm reading) basically reflects how warm or cool the heating coil will heat up in the tank to vaporize the e-liquid. Lower numbers (lower ohms) will burn hotter resulting in a warmer vape. Higher numbers (higher ohms) will burn cooler resulting in a cooler vape.

To figure out what power (volts or watts) to apply to the coil, start out lower and work your way up higher until you notice a burnt taste, then work back down to a satisfying vape.

If your power setting is too much for the coil, the MVP will alert you that the resistance is too low for the setting, or it will just refuse to fire the coil. This is what protective circuitry is all about. Mechanical mods do not have this.

Looks like they answered the question. the 1.8Ώ on the atomizer stands for 1.8 ohms. That is an electrical term used to determine how much the wire resists electricity. Keep in mind, the wire is SUPPOSED to resist electricity.. it uses the resistance to create heat. Just keep that 1.8 ohm setting in your head.

As far as the wattage goes... start low, and go up until you're satisfied.

I agree with Neal on the watts. Increase about a watt at a time until you either like the vape or it tastes a bit burnt. If you get the burnt taste back down until it stops that and a bit more and that's the highest power (watts) you'll be able to use with the aero mega tank, the head you have in it and that juice.

OK, so your coils is SUPPOSED to be 1.8, but your device is telling you it's reading 2.0.
That is common, it's pretty close, and it's OK.

You have your device set to deliver 9.5 watts, that's fine as well. If you like, you can turn it up a little and see if you like it better. At some point, it would be "too hot" for you, or might even "burn" the wick if it can't stay wet at that high a setting - it would taste or smell bad - so you turn it back down.

With a coil about 2 ohms, you're not going to do anything unsafe - it's just finding a setting that you like (watts up or down).


so i just got this innokin mvp 3.0 i use a aero mega tank they are using 1.8 atomizers when i look at this led i got the watts at 9.5 the leg has the thing beside it which im sure is the resistance is 2.0 is that bad im confused at what this means do i monitor that or what

Hi DeathFox and welcome.

Your atomizer (Aerotank) uses a dual coil, so you'll need a bit more power (wattage) than you'd need with a single-coil atomizer (like ProTank).

Maybe this will help you understand the relationship between watts, volts and ohms:

Disclaimer: This is the most simplistic explanation and is addressed to new vapers or vapers who are happy within the recommended "just right" power zone (4.5-8 watts) and use stock coils.

Ohm's Law as it pertains to vaping is really not that complicated--and it's very useful when you want to know what you're doing.

Voltage and wattage are often misunderstood by new vapers. Wattage is the power (heat, sweet spot) that your PV (battery and atomizer) generates. Wattage = Voltage (of your battery) squared divided by Resistance (Ω) of your atomizer [P=V[SUP]2[/SUP]/R]. If you're not good at math, don't worry, use this easy calculator:

Online Conversion - Ohm's Law Calculator

Of course, if you own a VW (variable wattage) device, you don't really need this calculator because your device will do the math for you.

The wattage you want, especially at the beginning of your vaping career, should be somewhere between 4.5 and 8.5 watts per coil. Anything lower than 4.5 watts may not vaporize your juice properly and will not produce enough warmth and vapor. Anything above 8.5 watts increases the risk of burning the filler in your cartomizers (if you're using them) or dry with your clearomizers.

There are, of course, other variables, like eliquid and JDD (juice delivery devices) that you're using on your batteries. Seven watts on a filler type cartomizer may feel different than the same 7 watts on a fillerless clearomizer or a dripping atomizer. The same is true for different eliquids; tobaccos, chocolate and coffees generally require more wattage (heat), while fruit and other delicate flavors do better with less heat. Everyone's sweet spot is different--those are just very general guidelines.

If you are using dual coil atomizers, things get a bit more confusing. Dual coil atties consist of two coils configured in parallel, which means that a 2.1Ω atty is really two 4.2Ω coils--so you have to calculate your wattage based on the 4.2Ω number--not 2.1Ω--roughly. Dual coil atties require more wattage than singles, but not quite twice as much. They produce more vapor due to increased surface. I usually increase the power (wattage) by ~50% when using dual coils; for example, if I like 6 watts with a single coil atty, I start at 8-9 watts with a dual coil atty. That's just my preference--YMMV. When in doubt--start low and adjust up as needed.

If you are interested in high wattage (and/or sub-ohm)vaping, that's a different conversation altogether--and not my area of expertise. :)

Experiment and you'll find your own bliss in no time!

The chart below is a good guide to safe vaping, even though some think it's a bit conservative.

Most coils are stamped on the side telling you how many watts are recommended for that particular coil. Those ratings are not perfect but it's a good chance you will find your happy spot in those recommendations. I'm not familiar with the tank you're speaking of but I know when I started vaping with a Nautilas Mini I had it 3 weeks before I realized the coils had that written on them

Welcome to ECF, DeathFox.

I use the Aerotank Mega previously with the MVP 2.0 (an older version) and now with an IPV Mini II. Using the 1.5 ohm coils, I normally set it at 9.5, but might change it slightly depending on the juice I am using at the time. As others have stated, start low (maybe at 7.5) and crank it up a notch at a time (if like the MVP 2.0, .5 increments) until it suits you or you start getting a burnt taste. It's a bit of trial and error, but that is the great thing about variable voltage devices.

Good luck in your search for your "sweet spot"! Let it be part of the fun rather then a nuisance. Happy :vapor:!
