Voltage Drop Evaluated

[Kemosabe]

we see lots of talk about voltage drop. but i'd just like to get some opinions on exactly what numbers we as vapers consider acceptable, what we consider great and whats considered not-so-great.

from what i can gather:

1V or more = not good at all
0.75v = okay
0.5v = good, great possibly
0.25v and less = outstanding

is that accurate? please list the values you personally consider outstanding, good, great, ok, horrible, etc.

FYI im looking for values based on a fully charged battery underload. i know preferred resistance will factor in, so might as well mention what your's is.

Those numbers would depend on the resistance of the coil that was on the device when the voltage drop was measured. For instance, .5v drop at ~.30 ohms would be very acceptable to me(borderline great) and I would very much enjoy it but that same .5v drop at around .8-1.0 ohms and I would not be happy/satisfied at all. Lots of variables to consider with voltage drop.

I would simply do it with three categories, and this would be my preference with about a .30 -.50 ohm coil

0.7v to 1v drop - Mediocre at best to borderline bad, I would use it but I would definitely be fiddling with it at some point to attempt to remedy the bad voltage drop with it.

.4v to .6v drop - Very good, Borderline great as you get closer to .4v and I probably wouldn't fiddle with anything to attempt to improve it.

Anything lower than a .3v drop - Outstanding, would be taking it apart to study what makes it such a good low internal resistance device so I could improve other devices.

Too much is focused on mod when it's brought up, and not the battery... edit..type being used.

Using a battery to determine voltage drop doesn't give an accurate measurement of a mods conductivity since when loaded the battery voltage will drop based on the condition of the battery and the load. To measure voltage drop accurately would take a laboratory grade power supply and meter. I would be surprised if even the worst mod had an actual drop of .1 of a volt.
Using the 510 screw on meters provides good information on the condition of the battery but not much more.

I would like to see reviewers come up with a standard for making these measurements so everyone gets the same results. For example the voltage could be 3.7 +- .01 volts and the load 1 ohm +- .01 ohms then measure the voltage drop. Or maybe it could be as simple as using a conductivity meter start using that instead of voltage drop. By the way, conductivity is measured in Mhos which is the reciprocal of Ohms.

^conductivity meter?

^conductivity meter?

yeah id like to know more about that as well.
