Getting Watts right for each coil

[Bob K.]

Hi all, I have been vaping for about 5 months. Went from a Crown Seven to iTazte VV and now with a Vamo V5.
I understand how Volts / Watts / Resistance works but i am missing something because If i use my Aspire Nautilus tank it shows it a 2 Ohms. If i Use any of my iClear 30S tanks, which also shows 2 Ohms, I have to use lower Watts in order to not get a burnt taste. I would think since the resistance is the same it would be the same power but its not.
With the Vamo and Nautilus tank, I set it for 3.0V then switch to Watts and use 10 Watts for a perfect taste and smoke.
With the iClear 30s, I leave it at 3.0V but use 7-8 watts. Any higher and its burning.
With the iTazte VV, I use to toggle between 3.3 and 4.0 V, (never played with the Watts on it).

So 3.0 V seems low to me but works and that's fine.
I just don't understand why tanks with the same resistance need different watts. Are iClear 30s coils just cheaper and therefor cant handle the higher power?
Any ideas or thoughts? I would just really like to understand what is happening.
Thanks!

It has to do with how efficiently the tanks wick -- if the wicking can't supply the coil with fresh eliquid as it is vaporized, you'll get dry hits/burnt taste. e.g., an iClear30 might be fine at 7 watts with an 80/20 or 70/30 eliquid, but may give dry-hits using a 50/50 eliquid, whereas a bottom-coil tank wicks differently and might be fine. Of course the bottom coil is more prone to flooding and will have a cooler vape, as there's tradeoffs to everything.

Makes sense, I have been using 60/40 but just ordered some 70/30 to try so that. Thise iClears are wicks that run the length of the tank so i have tried to always keep them full so they are covered.

Can also do primer puffs -- where you puff on it a few times without pressing the button, and with top-coils giving it a quick upside swirl so the eliquid gets up onto the coil faster can help.

I don't think you understand how vv/vw works. You can't use variable voltage and variable wattage at the same time. You're either in voltage mode or wattage mode. Or I'm just misunderstanding your first post and you do get it. Not really sure.

I do do understand that. I use it in Watts mode, i guess what i meant was that it seems higher on the spectrum in watts mode than Volts for some reason. In Volts i have to keep it around 3.0 - 3.3 on the Vamo V5 where i use to use 3.3 to 4.0 on the iTaste VV, and in Watts mode i use 8-11 on the Vamo. Almost seems like the output in W mode needs to be higher than in V mode, And i dont mean just a higher number. I mean higher on the scale of the available range for that mode. Which does not make sense but from experimenting seems to be the case. I am learning more that the fluid has a big impact on this as well. Found a thicker peppermint and certainly can use more power with that than thinning fluids.

Not sure that I totally understand what you're saying. Are you say that you are getting the same vape experience at 3 - 3.3 v as you are at 8-11 w? If so and your resistance is in fact 2 ohms, that's bizarre as 3 - 3.3 v will output 4.5 - 5.4 w.

Honestly, trying to figure out why different combinations of gear and settings deliver different degrees of performance will fry your brain. The factors that affect performance include aspects of thermodynamics, aerodynamics, hydrodynamics, electronic theory, metallurgy and probably a few others I'm forgetting. Change one thing about a setup and you affect some part of those factors. If you put a specific atomizer on a specific power supply and figure out how to make it perform in a manner that makes you happy, mission accomplished. Don't get too concerned with "I changed variable X and I thought Y would happen, but Z happened and I don't know why".
