To Ohm or Not to Ohm

[Low Budget]

So I have done a bunch of reading on Ohms/ Volt/watts. I am by no means an electrical engineer so it’s a bit confusing to me. It appears VW is better than VV because in VW it will automatically adjust your volts based on the resistance (ohms) of the carto/ atty. So my question is what does it matter if you run a 1.7 ohm, 2.0 ohm, 3.2 ohm etc carto or atty? It seems like the ohm difference was merely a way of adjusting the watts of a fixed volt or VV device.

What am I missing?
Sorry if this is in the wrong forum but I am using my first VV/VW device- The awesome VAMO!!!

I don't think you are missing much. VW just gives some a convenience of not fussing much when switching atomizers. Others don't pay any attention at all and just adjust volts or watts to taste. It is all in what you get used to and appreciate. I have both VV & VW devices. I tend to leave the watts alone when switching attys, but play with volts. No big deal, no better or worse. just what you decide you want to do.

I also adjust my watts due to taste I accredit that to the differences in the juice. I'm was more curious about what ohm cartos to buy. I have been buying 1.7 ohm while I was on an eGo device and have gotten good performance from them on the Vamo on VW. Just wondering why most people run a higher ohm coil? Ibtanked sells their kit with a 3.2 ohm carto. Just trying to find out if there is any benefit from switching from 1.7 ohx to x.xx ohm?

VV and VW have their place depending on how you want the Vamo to work for your particular needs. Personally, I used VV mode because different juices may taste different at different temperatures. The same juice might even taste different in a different delivery device. I always find myself tweaking the voltage a little here and there. Sometimes I run a juice on different voltage just to experiment with the taste. I also use VV because I run dual-coil carts which the Vamo falters at.

In any case, if you haven't already seen one, HERE'S a Google link for charts you can take a look at. None of the voltages in these charts are "gospel" but more for info so you can see what other people sort of run at. Also, HERE'S a very handy online voltage/wattage/amperage/ohm calculator.

Hmmmm...

Ohm nom nom nom nom nom....

Sorry I haven't had lunch yet...

Like what others said, flavors differ on how hot they get.

Doesn't raising the wattage accomplish the same thing?

Yes it does.

However, the premise behind VW is that it allows the Vamo to maintain a specific wattage no matter what delivery device (within reason), you attach to it. Now while this premise is a good idea, in practice, it never really works for every situation, thus, everyone using VW will, more than likely, continue to adjust the wattage even when in VW mode... which kind of defeats the purpose of VW in my eyes.

Then again, if you had a 1.7 ohm cart and a 3.2 ohm cart and switched between them on the Vamo set to say, 9 watts, the Vamo in VW mode will get you close by supplying a voltage that will take you to 9 watts for either cart. Then, you can adjusts watts to taste. So there are advantages to VM also.

Ok I think what I am getting is different ohm cartos on a VW device are useless. Per this chart the sweet spot is approx 4.5-6.25 watts ( I run higher) running any ohm carto. I guess the watts just takes out the math. Nice to know I don't have to be picky about what ohm carto I get. Thanks for the help in understanding !
