You want to be able to change the voltage to get the vape you like
Changing the volts will make the vape hotter or cooler
or get the juice vaporized faster or slower
depending on how you like it.
If you use a 2.8ohm coil at 4.5 or 5volts
the vape will be rather warm, some people like that, I don't.
I ahve found that I like mine around 1.2 ohm at around 3.3 to 3.5 volts
some times higher.
Volts should start at 1.2 times the ohms and adjust from there
So a 2ohm atty or coil should be around 3.2 volts going higher will be warmer
going lower will be cooler but take longer to vaporize
Too much and you will burn the juice. Bad vapes.
On a mech, you will have to adjust the coil to the vape you like
You will be pushing 3.8v for a while then it will drop off
so, the lower the ohm, the hotter the vape, and vice versa
but the trade off is, higher ohm coil and the battery runs out faster
Mechs are good only in certain situations. In my opinion.
Mechs (aka Fixed Voltage) is said to be a step back by some
and a "who needs VV?" by others.
I would also suggest a Vamo, I have a Vamo 2.5 which I don't use anymore and a v3 that I pulled out to play around with tanks and stuff.
Found that it is still quite usable. But I have a Provari that I use mostly and recently a Nemesis Mech, that I am pulling away from
Don't see the point in a mech. I vaped on it for several days and different atty's
I get a better vape from my Provari and the Vamo actually. It just feels better, hard to explain.
And I wouldn't trade my Provari for anything other than a better version Provari.
If you are going to go further with a VV mod, then I would highly recommend a Provari.
Yes they are expensive, but what you get is worth it. And so is the company.
You won't go wrong with a Provari and a Kayfun v3.1 ES.
However, on the cheap, the Vamo is definitely a very good choice.
I would also highly recommend a VV/VW mod that you
CAN change the batteries on.
Batteries go bad, regardless, so getting a mod that has a built in battery that takes
work and know how to replace, imo, is a waste, no matter how good it might be.
It's possible to last several years, or only one. There is no way to calculate that.
No one can.
Rumor has it that Provari v3 is coming and rumor is, it will be VW. We will have to wait and see.
Provari 2.5 is only VV, but to be honest, there isn't a huge difference between VV and VW.
Just plug in Ohm's law calc
1.8ohm
4 volts
= 9 watts
and vice versa
VW all started with the notion that you could swap atty's of differing ohm's and not have to adjust the volts
it would automatically do it for you.
This just doesn't matter. You will still have to adjust the settings, no matter what.
And there is the notion that you get something different from using Watts rather than volts
again, it's doesn't matter.
So, don't worry about whether or not it is VV or VW. In the long run it makes little to no difference.
Only till you start getting into the super sub-ohm of .2 ohm and 20+ Watts
You want the Watts to get the Amps I guess. It's a little different in that realm I think.
Others can explain this better than I can.
Ultimately, get what works for you. Even if it is cheapo over the counter cig-a-likes.
But we all know you want something better than that.
One last thing,,, changing the voltage will change the flavor, from muted to full on flavor
depending on the atty. and vice versa, however, some attys and some juices, will actually taste worse or better at different voltages.
