I carry 2 PVs at all times. A Prodigy at 5 volts, and a Chuck at 3.7 volts. I hit one 2 or 3 times, then let it cool while I hit the other 2 or 3 times.
Other than the difference between the 2 flavors, I can't tell the difference.
And that's part of the problem, really. There are too many variables when I use these.
2 juices, 2 carts, 2 cartridge fill setups, 2 atomizers...
The only fair way to compare is to move the atomizer & cartridge between the two mods. If I have time and can remember to do this, I'll try it tonight and get back to you.
And that should tell you that there's more to all this than just the voltage. You'll notice more difference by changing your juice.
Then again, I own 11 big-battery PVs. And I won't buy any more unless they're 5 volt models. That should tell you something too.
