Below is an ohm's law calculate if you want to play around and see different ohm volt combinations.

Any two given values will yield the missing ones.How do you figure your "current"? Is that your battery mah? Or do you even need to enter that?
Most cartos are of the LR/Dual coil varieties. At 5V with a 2.0 ohm, which is the most common, you get 12W? That's burning your juices unnecessarily. There's probably an advantage for VV if higher resistance carts are cheaper. They are not. So why not vape at 3.7V - 4.2V with a 2.0ohm? Some say higher resistance cartos last longer. This is where the confusion lies. I always thought that lower resistance means thicker wires or coils while higher resistance means thinner wires/coils. You can see this in light bulbs. It's so thin that current just barely flows and at the point of burning, thus produces light.

This just isn't accurate. If vaping at 4.7v - 5.0v burned the eliquid, then no one would do it. Instead, it provides warmer, fuller vapor. I use dual coils at 4.7 - 4.9 volts and there is no burning of the eliquid. Just nice warm, full vapor with nice flavor. I've also used LR attys/cartos on 3.7v models and in comparison to standard resistence attys, the LR's degrade more quickly.
I'll take your word for that, man, and I may go down that route. Anything economical makes my senses more receptive. LR's degrade more quickly. Okay. Certainly makes SR cheaper if as you say they last longer.
.....But WV2win, he did say that he wasn't going to use 3.7 anymore, and some of us dissagree with that.
Liking 5v vaping is not a valid reason to not also like vaping at other voltages........
I agree with you WV. I wish I had all of the $ back that I spent on 3.7v products. Batteries for the most part. While I applaud those who can get by on 3.7v I am not one of them. I still believe that 5v and up is a better way to mimic an analog......at least for the TH aspect.I'm not against someone liking the low throat hit and cold vaper on a 3.7 volt model. Everyone is different. I regularly recommend 3.7 volt models. What I find is an effort by some veterans to only recommend and promote 3.7 and smaller volt models as the only option, especially to new vapers. This type of information limitation is quite unfortunate.

Got news for ya, this little key ring thing I'm vaping right now is not exactly what I'd call "low throat hit and cold vaper".
But I do agree that there is a lot more than one way to get a good vape. So 3.7v is not the only show in town by any means.
......... Other people want more hit than I do and a higher voltage is good way to get it.
