Hello SMP 1981 and welcome to the forum. I have an iStick 50W and Nautilus Mini. I set my iStick to watts (you regulate one and the iStick adjusts the other) and for most e juices I run around 12 to 13 watts. Each "flavor" could have a different "sweet spot" so you'll just have to experiment with wattages/volts and adjusted air flow on your Mini's. Good luck in your vape journey.

sorry no but vaping really is all about personal taste
so what works for one may not work for the other ;)
the general rule of thumb you set your volts +2 to what your ohm is....
so a 1.8ohm would be set to 3.8v or 7w and then adjust accordingly to taste...me i've found i like to stick between 8 and 9 watts but on some more harsher vapes i'll drop it down to 5 or 6 watts

Got a 1 ohm I tend to run about 14 watts and a 0.8 that's more like 18 - 22 watts. I find if I back off the airflow and the power and take longer hits I get better overall flavor, but I really think it's fairly subjective. I know some would enjoy running my setups at significantly higher power. I don't really like a hot vape personally. To each his own.

Hi SMP and welcome to ECF!

First of all, you need to know that your iStick 20 runs at about a full volt higher than the display indicates, so you should proceed with great caution--especially when you use a single coil atomizer like your BVC. If you have a new, cotton version, you're running a risk of burning that cotton in an instant if you apply too much power. Start at the lowest setting on your iStick (3 volts or so--that's really more like 4.2v) and pray for the best. ;)

In the future, I suggest you get a more precisely calibrated battery (iStick 30, Heatwave Defender, MVP 20 or 4) and use your iStick 20 with dual coil atties (GS Air or Aerotank are my favorites).

You may find this helpful:

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.
