Difference between VV and VW?

[iRyyy]

Hello,

I know that this is a noob question, but can anyone tell me what the difference is between variable voltage and variable wattage? I was thinking about upgrading from my Twist to a VAMO and noticed that it has both VW and VV. Thanks for your time.

VV will be set the voltage and as resistance changes in the atty the vape will seem to change (as the wattage changes) just like your twist.
for example when the coil starts to get dirty and built up you usually bump up the voltage a little as the resistance changes. VW will do this automatically.
the idea behind VW is set the wattage and the voltage will automatically readjust itself no matter what changes, even if switching to a different atty keeping the vapor more consistent.

this is the most basic explanation.

some notice no difference between the two, some really love VW over vv.

the best thing to do is get it, and just play to see if you like one over the other. its not going to hurt anything are magically make things different.

Trasher's explanation is a good one. It could be summed up like this:

A vv device set at x volts will get your coil hotter or cooler depending on your coil's resistance (ohms).

A vw device set at x watts will get any coil, regardless of its resistance at the same temperature. Thus giving you the same vape experience on any of your atomizers.

Note that this is a rule of thumb, and coil temp will vary depending on other variables such as wick thickness and so on.

it will give any coil(within limits) the same amount of power but what temperature the coil reaches with that power depends on many factors including heat capacity of the coil, wick and the surrounding structure, heat transfer speed between all these elements and even how hard you drag and the size of your mouthpiece.

You are absolutely right!

I mean it as a generalization... a vulgarization if you will.

thanks for your help everyone!

ive been vaping for 6 months and have several vv vw devices, this is by far the best explanation I have seen on it. Thanks guys!

VW is closer to "set & forget". Good for a new vaper.

watts is the end product of Volts x Amps. it's how much power is being dissipated by a coil. At any given voltage the amps will change if the ohms/resistance changes, and will change the end result (watts). VW is desirable because you can pretty much take the math out of what you're doing and just put in the desired power output and it will vary to voltage to meet that.
