You can't change the wattage without changing the voltage. Wattage is the end result. The end cannot create the beginning
Volts are a measurement of input, ohms are a measurement of resistance and watts are a measure of output.
With Variable Voltage devices you manually set the voltage level (input) based on the resistance (ohms) of the delivery device to produce the desired output level of power (watts).
With Variable Wattage you set the device at the power level you prefer (for example 8w) and the device will measure the resistance (ohms) of the attached delivery system and automatically adjust the voltage to produce the wattage it was set at. (For example, if the delivery system has 2.0ohms resistance, the device will adjust to 4v to produce 8w; if the resistance is 3.0ohms, it will adjust to 4.9v to produce 8w). VW devices also have a VV mode, which you can switch to if you choose.

I'm gonna tack this onto Ocelot's post: the short answer is yes.
Voltage is volts, current is amps, and watts is current multiplied by volts. It's a little easier to imagine with a mechanical mod, where your voltage doesn't change (your battery dumps it all out at ~4v) but how much current/amperage gets drawn from the battery depends on how much resistance is in the coil. So with your 4v battery, you'll pull more amps/current with a 0.5ohm coil than you would with a 1ohm.
If you have a VV/VW mod and a 2ohm coil, and set it at 8w, it'll put out 4v. If you set it at 18w, it'll put out 6v. You'll eventually reach a voltage limit for your device/batteries (something like a Sigelei 100w is 8.5v I think), but you can still pull out more *current* or amperage like in a mech mod by using a low-ohm coil. So you'll be using the same voltage, but more current, and hence reaching the 100w which you couldn't do on a 3ohm coil or something.
I think. Someone'll correct me if I'm wrong and probably be purring while doing it.

No, as you increase wattage, voltage adjusts to meet that setting. Most use variable wattage modes because its more consistent than variable voltage.
As it's been said on variable devices that let you change on or the other it's used ohms law to balance everything out. So when you change one the other changes according to the law. It would require a wormhole or something to modify both independently.

I think I get what you're asking. Your voltage IS changing, you just can't see the change because you don't have the decimal places to display it. On a 1.8 ohm coil, 10 watts is 4.24 volts, 9.9 watts is 4.22, 9.8 watts is 4.2 exactly, and so on. For MOST devices, the voltage is still changing to give you the wattage you're set for.
The biggest advantage to using VW mode, though, is consistency. Within a standard range, a 10 watt vape is the same, regardless of the voltage and resistance it takes to get there. So say you are vaping a 1.8 ohm coil at 4.2 volts to get 9.8 watts and you pop in a new coil that's 2 ohms, and you want it to vape the same. In voltage mode, you can do the math with ohm's law and come up with the correct voltage to get your 9.8 watts (about 4.4 volts), then change the setting. If you're in wattage mode, on the other hand, you just leave it set at 9.8 watts and your mod does the math for you. You don't have to mess with it. Make sense?

The goat jinxed you. It's obviously spreading it's pain past chicago now; at least you're not a pitcher.
