Within the Vaper Community lies the wonderful world of Variable Wattage & Variable Voltage. There are ecig devices with variable wattage, variable voltage and even some with both like our LAVATUBE v2.5. If you’re already confused, don’t you worry we got you covered. With the help of our Tech Team, we were able to break down the main differences when using a variable wattage and variable voltage e-cigarette device.


Key Factors to Understanding

To really understand the difference between variable wattage and variable voltage you’ll need to understand two key factors: Ohm’s Law and the resistance of a heating element. Once you’ve got a grasp on what these two factors are, the rest will make much more sense.

Ohm’s Law

The Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship.

Now that you know what Ohm’s law is, here’s what Ohm’s law means for e-cigarettes:

The amps that pass through the resistance of a heating element will be directly proportional to the original voltage or wattage setting.

Resistance of a Heating Element

All heating elements have some sort of resistance in them called ohm’s. The resistance will change depending on the ohm’s of your heating element. Lower ohm’s will result in less resistance. For example, a 1.5 ohm heating element will allow for more amps (from your battery) to go through versus a 3.0 ohm heating element that will resist the amps (from your battery) from passing only letting a portion of it through.

Since there are watts and volts in all ecig devices, we’ll be breaking down how a variable wattage and variable voltage device works.


Variable Wattage in an eCig Device

A variable wattage e-cig device is like an automatic vehicle. After you’ve properly prepped your car and found your perfect settings, all you need to do is start the engine and drive. Like our Tech Team says, “variable wattage is where you can set it and forget it.” This type of device is recommended for Vapers that are looking for a different yet not specific type of vape.

How a Variable Wattage Device Works

A variable wattage device will give you the option to pick the wattage at which you want to vape. Once you’ve picked your perfect wattage setting, your ecig device does the rest to get you what you want while you get your vape on.

In a nutshell, this is what’s happening once you set your wattage and vape:

Your set wattage > Device auto sets volts goes through resistance > Your set wattage

For example:

Let’s say you set your wattage setting to 12 watts and start vaping with a 3.0 ohm heating element. While you vape your device automatically sets the volts to 6 so that when it goes through the heating elements 3.0 ohm resistance, it’ll end with the 12 watts you asked for.

Set it and forget it

First, make sure to properly set up and prime (if needed) your heating element. Once your heating element is good to go you’ll want to start vaping at a lower setting. To find the setting that best suits you, change the wattage settings with every one or two vapes you take. When you’ve found the setting you like the best, leave it on that setting and vape on.

Variable Voltage in an eCig Device

With variable voltage being similar to a manual vehicle, it’ll take longer to learn how to find your perfect vape. Variable voltage is recommended for Vapers that want a specific type of vape and don’t mind taking the time to find it.

How a Variable Voltage Device Works

A variable voltage device will give you the option to pick the voltage at which you want to vape. Unlike setting a variable wattage device, you’ll need to do some math to figure out exactly what you want to end with.

In a nutshell, this is what’s happening once you set your wattage and vape:

Your set voltage goes through resistance > Wattage

For example:

Let’s say you set your voltage setting to 4.5v and start vaping with a 3.0 ohm heating element. The 4.5v will go through the heating elements 3.0 ohm resistance and end with 6.75 watts.

How to find the perfect vape

After your heating element has been properly set up and primed (if needed), start vaping at the lowest voltage setting. Take one or two vapes to give you a good idea of what this voltage setting has to offer. If the vape is to light or airy, adjust the voltage up and repeat these steps until you have found your perfect setting.
