I didn't want to derail another thread but, I don't want to get blowed up either (Resistance/Volts)

Can someone help me understand or if I'm reading this wrong?

I have a couple of the nautilus Minis coming tomorrow so, I was reading through other's experiences. Some mentioned they were setting theirs at 4.2 - 5.0 volts. I've been using the Resistance Chart. The nautilus ships with a 1.8 ohm coil. If I follow the line on the chart for that resistance and get to 4.2 - 5.0 volts it indicates that I may damaged or burn out the coil. What am I missing?

Thanks!


Apologies for the small pic...

The chart is correct. For a 1.8 ohm coil I would use nowhere near 5.0 volts. A 1.8 ohm coil sweet spot is somewhere in the 3.7-4.0 range for me. If I were you I would start out at the lowest voltage your mod has and slowly increase the voltage til you're satisfied.

Thank you! Sometimes I don't trust these old eyes. I'll stick with the chart.
Appreciate the help.

Same thing has crossed my mind from time to time.
As bm2112 mentions, start on the low side and work up to find what best suits ya.

As for the what's missing part, I wonder if the range values on those charts was established based on single coil devices and aren't that awfully relevant with respect to the newer dual coil devices.

Just pullin' lint here, I don't really know meself (-;

People who are using high voltage/wattage are building their own coils.

I've used 6.0 V on a 1.7 Ohm dual coil (factory made) in a Nautilus with no problems. This is with a VS DNA30.

Chances are you're going to not enjoy the vape long before you're in any kind of danger zone. Take the above advice regarding starting low and adjusting up to your sweet spot.

After watching several reviews where people far more experienced than me were pushing the new BVC coil in the mini to 5 + volts or in one case 18 watts with great results, I started at 3.8v and have inched up to 4.4 v on my Provari and it's simply fantastic in taste and volume of vapor. Whatever the charts say , these new BVC coils can take more and deliver great!

The thermodynamics of one type of atomizer can be so different than they are for a different type anymore that there would have to be a different chart for every topper made for them to be of any relevance.

The Rule of Charts:

Dump the charts. They don't take into account anything about the actual design of the device. The resistance of the coil is only a part of the Equation of Vaping. The liquid(s) you are using, the flavor components and how they react to heat, the age of the coil, the PG/VG ratio... none of that is on that chart.

You just start any new coil at your lowest available voltage/wattage setting and move it up until you hit the flavor and vapor production that's good. A chart does not figure that out for you and over shooting because "the charts says..." can kill a coil in a matter of minutes.

Thanks y'all. I'll take it slow!

You will be surprised at how far you can push these new coils. I certainly am that's for sure!

The Chart is for Reference. And Not a Definitive Source of what will happen for a given Voltage and Ohms. Think of it as a Rough Guideline.

BTW - Whenever a Thread is Started like this, you are Always going to get Posts that say...

"I use ___ Volts with a ___ Ohm coil, and it Works Fine!

and,

"I use ___ Volts with a ___ Ohm coil, and it Completely Sucks!

These are for Reference Only also.

Yes, our beloved charts are getting a bit outdated and haven't kept up with some of the new advances in coil design, but still function adequately to provide a conservative starting point.

Yeah... That Chart could do with a Face Lift.

Here is one I did for a Member which shows Lower Ohms.

I had a couple of Extra Minutes so I did a Quick-n-Dirty Sub-Ohm Spreadsheet.

There wasn't much need to put much Formatting on it. Because it is Almost All in the Read.

BTW - Notice how Fast the Watts go up as the Ohms drop from .3 to .1

And how the Graph of the Watt Curve goes Vertical as the Value in the Wattage Equation's Denominator approaches Zero.

Thanks zoiDman and all for the info and suggestions. Like when you dime an old Fender amp. That burning tolex smell and crackling speaker tells you "Step back a little." But goodness, it sounds good. My personality needs for me to have some guidelines to get started and then go with the feel.

Appreciate all the help.

"Dime an Amp"... I haven't heard that Term for years. LOL

Cool.
