It's late and I might be getting a bit foggy but I remember reading somewhere just today that a given voltage with a higher resistance will consume less amperage than the same voltage on a lower resistance. If this is correct then shouldn't the opposite be true? Shouldn't say a 2.4 ohm attachment use less amperage at a higher voltage than a lower voltage setting? If so then lower amperage = longer battery life... correct?
Exactly. Power is expressed by watts, which is simply voltage x amperage. For any given voltage higher resistance means less amps, so less watts, less power consumed. Higher resistance means less, amps, less watts and less heat from the coil as well, less chance of a burnt taste. But if you go too far with the resistance you get too little heat to vape well. You can modify heat as well by drawing more or less air across the coil as well.The higher you raise the resistance the softer you will likely have to draw to get good vapor as a strong draw will cool the coil too much.
The coil can hit about 1500 degrees I think, well over a thousand anyway. All that keeps it from burning is liquid and air draw keeping it cool. Everyone has to figure out what wattage works best with their wick system and their preferred air draw that keeps the wick wet and the coil in the right temperature range to vape but not burn. If you have a strong draw a lower res might be better, if you like a slow easy draw then a higher res might work better for you. If your ecig wicks really really good a lower res might be better and if it doesn't wick that fast a higher res might be better.
It's a balance you have to find for yourself as it's different for individual devices and individual air draw habits. Then if you go to a higher voltage you kinda have to figure out a whole new balance at that higher voltage.
That's been my experience anyway. If your using variable voltage I would go for higher res, 2.4 at least then crank voltage up from minimum a little at a time till you hit your sweet spot.
