Curious on this.
The device doesn't change physics. Both Joule and Ohm have some well known rules describing this.
The intent is not to be argumentative. But given it's the newbie forum I feel the need to question the statement, as all things being equal, the stored amps in the devise defines the longevity, not the device itself.

I'm no electrical engineer but I and hundreds of others who use mega dual coil cartomizers on the Darwin report the same success. I think it has to do with the fact that the Darwin is a variable wattage model not variable voltage like the Provari as well as the different protection circuits built into the two models. When I use dual coils, I put the Darwin on 12.7 watts and it registers 4.6 volts while vaping at 1.6 or 1.7 ohms.
And I am a very heavy vaper. When I vape using standard resistence cartos/attys, I get 21 hours on a charge. With the dual coil, it cuts it down to 12 - 13 hours which is still great and since it's also a pass-through, I can vape and charge, if need be at the same time.
If you come to the Atlanta Vape Meet in February, I will show you.
Again, another advantage to the Darwin.
