You can figure out what wattage you like by calculating the voltage and resistance you usually vape at. The formula is

W (wattage) = V (voltage) squared times resistance.

So for example if you usually vape a 2 ohm carto at 4 volts, you just do 4 squared times 2 which equals 8 Watts. It might sound complicated but once you find out what wattage setting you like, you can just leave it there no matter what carto you put on it. Although you still may want to fine tune a bit. Also, there are ohms law calculators online that you can use for this. Just google "ohms law calculator".

Actually the formula is W (wattage)=V (voltage) squared divided by R (resistance)

At the risk of being rude, you got the right answer, so I'm sure you performed the calculations correctly, but the formula listed is wrong. In this example power would equal 32W (V squared X R = 32W).

Power (Watts) equal voltage squared, divided by resistance, in this case - 4 Volts squared equals 16, divided by 2 Ohms, equals 8 Watts.

LOL That's what I said! :toast:

I got the Vamo v2 because of the "set it and forget it" wattage setting. Haven't used it yet though as the batteries have not arrived yet. Really looking forward to not having to adjust volts for every tank and resistance I put on my mod.

I suspect people adjust their wattage just as much as they did their voltage. :)

Except when the current is fixed. In this case power equals voltage times current: P=U*I.
Current itself is calculated as voltage divided by resistance: I=U/R. For currents that are below the current limit and for mods without short-circuit protection, we get the more commonly-used formula P=U*U/R.

AFAIK, for Vamo V2 the current limit is 5 amperes; once you hit that point, it doesn't go any higher when you increase voltage or decrease resistance.

I am more of a set it and forget it sort of vaper so I run my vamo in Watts mode. GIven most of my juices are fruits I don't find I need to adjust it much once I get it set.

People who are picky about each individual juice needing exactly the right power level for that juice probably do better running in volts mode as it increments are smaller.

    Quite a few of the newer APV's have a lot of options that an individual doesn't need & will probably never use. Nice tho' that you can pick & choose which you would like to use.

    Oh and, use whichever formula you care to use, your juice doesn't really care.

    I just received my Vamo V2 in the mail today and never used an adjustable one (Used eGos till now) and feeling so lost. I understand clicking the Up until NO2 shows, what else do I need to do to try it out? I have iClear 16 is there anything I shouldnt do that will damage either?

    Set it to wattage mode, turn it up to about 7 watts to start and have a vape. Oh, and avoid e-liquid that can eat through plastics.
