I get around 4 to 5 hours of vaping time with my 14500 trustfire batteries with a LR attie.... normal atties I get 5 -6 hours... not really that much of difference.... I get a warmer vapor from LR atties and a lot vapor as well even using the same eliquid as always. If your woundering I vape around 4mls - 6mls daily.
I didn't say it was a 5v vape... I said an almost 5v vape.... and a lot of people use this setup... even if they didn't want to use LR atties a lot of vapors still want a small device.
warmer and more vapor is a fact Grimmer because double of the current goes through atty. But double the current means -50% to the battery life. If we meassure what is happening you will see that I am right. Ohms law is a law and we cant argue on this.
I agree with you that some people want a small device. I also agree that I have to make 2 kinds of small GGs to satisfy anyone
