Is There A Chart or Something?

[Mezzum]

I am probably not the first or last to ask, but I can't find the information, even searching...

Where can I find a chart or something telling me... If the OHM's equals (insert here), the maximum Voltage you can vape at is (insert here). (by maximum I mean one more volt higher, would trigger a failure)

I think duel coils throw a wrench into the mix, I also realize, my Provari and my VV Box from Madvapes, has some kind of protection in it. However, I have found, for me at least, taking cartos to their limit seems to give the greater vapor, knowing I am shorting it's life.

I just celebrated my first year of vaping on Jan 1st. A monumentous victory to me, yet still I am fiddling around trying to fine tune my vaping experience to nirvana.

I have my juice nailed down, I have my main gear nailed down (I hope). I am now bouncing around Carto Land trying to find the maximum vapor producing combo of OHMS + Voltage equals perfect.

I hope this makes some sense. As always, it is this forum, and you people who I could never repay for your guidance.

Thanks....

Congrats on 1 year vaping and being smoke-free!!


I'm not an electrical engineer but I'll try to help.

I think you're having issues, because the protection is getting tripped because low resistance+high voltage is increasing the amps above the level of the switch in the mods.

If you have an iPhone or a Droid phone, you can download a free Ohm's Law Calculator on the respective app store, or Droid Marketplace (hint: just search "Ohm's Law Calculator").

If you don't have a phone like that where you enter the known values (in Ohm's Law, you only need to know two of the 4, two know the other two values), just go here: Ohm's Law Calculators

Anything over 2.5 or 3 amps (not sure which), will trigger the protection, and throw E2 errors in the Provari causing it not to fire, or in the Madvapes VV mod, just cause it not to fire at all.

An example:
4.2V, 1.5LR Atty/Carto/etc, would equal 2.8A so to get it to go below 2.5A, you'd need to lower the voltage or use a higher resistance atty/carto/etc

I'm not sure if anyone made an actual chart. But here's a video by SteelJan on Youtube: Low Res, High Volts, 3.7V, 5V, VV? Wtf?!! - YouTube

Hope that helps!

Bizzyb0t is correct, the Provari cut-off is 2.5 amps. I usually use a 2.5 Ohm on my Provari, but anything is possible on the unit. The key to vapor production is power measured in Watts.

If you don't have an iPhone and want a simple calculator then this link will help you find which Watt is working for you and you can then use it to find a higher resistance and adjust the voltage to make the same power output. EIRP Calculator Put in the cut-out current of 2.5 amps and the resistance of the dual coil as measured by the Provari in this calculator and it will give you the Wattage and the maximum voltage. (If you run the Provari at this calculated voltage it will trip the protection circuit, so you would want to back it off by 0.1 Volt at the least.)

I'm not an electrical engineer, but I play one at work.
