Is VW really that simple?

[Tiktox]

I've noticed that you can have the option of VV or VW on many mods. However, having looked into the VV side of things and how you should calculate the safe voltage levels before frying the coil or liquid etc, it seems to me that changing Wattage can be dodgy. You can whack up the watts without a second thought for the damage it could do to your set up because you assume that the voltage vs resistence takes care of itself. In effect, VW is not as simple as it might seem.

Am I correct or is it even more complex?

Wrong, if you set it on watts the device will regulate the supply and not pop the coils whereas on volts the coil can simply pop as soon as the voltage gets high enough.

as above, plus to add if you do get burnt taste you just drop the watts to the level your happy with and leave. i vape on 11 watts. can stick any tank, dripper or atty on it ( as long as its over the 1.3 ohms limit of my zmax ) and happily vape all day long without any worries.

plus on most vv/vw devices they wont fire on anything under 1.2ohms so on most of your normal resistance attys 1.8-2.5etc they wont pop going upto 6 volts and you'll most likely get a burnt taste on your juice before that happens vv/vw is very simple and does exactly what it says on the tin.

I think "Variable Voltage/Variable Wattage" is a pretty poor way of describing these devices, pariculary to anyone who doesn't have a full grasp of Ohm's Law. It might be better if they were described as "Manual Voltage/Auto Voltage" devices. If you want to control the voltage yourself, then you need to take into account the resistance of the atomiser you're using. If, however, you want the same performance from your mod, regardless of atomiser resistance, then you set it to Auto Voltage (Variable Wattage) and you can change heads til the cows come home without any significant deviation in performance.

Having said that, even if you do opt to use the voltage variance on these mods, as is stated above, you're going to find that the taste gets pretty horrific before the coil burns out.

Ultimately though, VW is just as simple as it sounds, and it's far quicker for me to select a power setting on my mod than to sit with a pen and paper and work out what voltage I need to use to get enough of a hit without burning my juice.

Thanks guys. Uisgemann....I think the 'manual voltage/auto voltage' describes it pretty well :-)

Perfect explaination, ive just used this explaination to a work colleague as i was struggling to put what i meant into words. top job mate
