5 volt
vaping is very nice. E-liquid still has some flavor and the vapor is warm. 6 volt
vaping certainly degrades e-liquid flavor, but it is much more analog-like for throat hit and vapor production. I like both for the above reasons and find it very difficult to find anything to enjoy about
vaping at 3.7 volts (the voltage of typical screw-in batteries).
The one caveat is that high-voltage vaping (HVV) can kill your atomizers faster. Not because of the higer voltage, neccessarily, but because many of us often overheat the atomizer too often. This can cause stress on the heating coil and shorten it's life. If you can use a high-voltage device for 4-6 draws and let is sit for several minutes to fully cool before hitting it again, you may see no significant change in the life of an atomizer.
