 What is the difference between Variable Voltage and Variable Wattage?Many beginner vapers permanently stumble upon Variable Voltage and Variable Wattage terms. What’s the difference between them?

Explanations of some specialists that Variable Voltage changes the output voltage and Variable Wattage changes output wattage, is completely wrong.
Variable Voltage (VV).

Let’s look at the VV working process. The voltage from the battery is supplied to electronic board, after, it is directed at the output to the vaping device coil.

Let’s look at the VV working process. The voltage from the battery is supplied to electronic board, after, it is directed at the output to the vaping device coil. The board itself has a lot of different additional and useful functions – voltage regulation, protection from short circuit etc. But the main and the basic function of VV – the ability of changing the output voltage from board to coil. This is done with the variable resistor help or by pressing buttons.

So – Variable Voltage changes the voltage supplied to atomizer.
Variable Wattage (VW)
Now let’s look at how Variable Wattage works. The voltage from the battery is supplied to electronic board. But at the output the board changes not wattage but voltage. So the same as in Variable Voltage devices. Forget about wattage, because it depends on coil resistance and supplied voltage. At the output the VOLTAGE is changed not wattage!!

Then what is the difference between these boards?
The button on VV simply reduce, or increase the voltage supplied on atomizer. For example, your atomizer has 1.8 ohm coil, you apply 3.5 volts. If you will change to an atomizer with 2.8 ohm coil, applied 3.5 volts will not be enough, you must increase the voltage. But if you will return back the old atomizer with 1.8 ohm coil, you have to manually lower the voltage (VV is as a manual car, you must change the voltage applied manually).

VW works different the VV because it has a pre-built algorithm for voltage regulation depending on the load resistance (of the atomizer coil).
Well, let’s say, if the atomizers coil has 1.8 ohm, the board will give it 3.5 volts. And if you will change the atomizer to 2.8 ohm one, the board automatically (without manual adjustment !!) will give it 4.5 volts, (in other words, VW is like an automatic car which adjusts the voltage depending on the circumstances).

Well, but why VW needs adjustment button if it adjusts automatically?
For example, as said above, your coil has 1.8 ohms and VW adjusted it to 3.5 volt. But for you that’s not enough, you want more vapor, etc. That’s why the regulation button is need, a few clicks and the output voltage is changed to 3.8 volts.
