Vaporizer Variable Voltage And Wattage Explained

VV / VW Guide & Explanation

Before we start, there are a few things you need to understand about vaping & vaporizers and ultimately everything depends on which particular vaporizer you are using.

There are many possible variables which affect the taste of your vape;

1. Voltage of your battery

2. Wattage of your battery

3. Resistance of your heater coil

4. Blend of e-liquid (PG (Propylene Glycol) / VG (Vegetable Glycerin) ratio)

5. Nicotine strength of your eliquid

6. manufacturer of your e-liquid

7. Single top coil with wick

8. Single bottom coil

9. Dual Coil

If you have a basic fixed voltage vaporizer then your voltage and wattage are set by the manufacturers, as is the resistance of your heater coil (assuming you are using the original or straight replacement clearomiser). This means that the only changes you can make to affect the flavour of your vape is to adjust, change or blend your eliquids.

Different e-liquids tend to work differently in different devices. Some ‘burn’ relatively easily, producing an unpleasant taste if they are over heated. With a fixed power device, you have no control over the heat that your coil produces, so the only solution is to change to a different e-liquid strength, flavour or manufacturer.

This is where VV and VW devices come in as they allow much more control over the vape you produce.

Evod Bottom Coil Atomiser

This Evod 1.6ml bottom coil atomiser has a single bottom coil which is always submerged in e-liquid giving a more consistent vapour

This 3ml bottom dual coil atomizer is fully rebuildable and is designed to work with VV/VW devices.

Dual coil atomiser

This is a dual coil atomizer, with a bottom coil as well as a top coil fed by multi wicks. Designed to give the best performace vapour with variable voltage/wattage devices.

If you are using a fixed voltage battery, there isn’t much point trying dual coil atomizers as they don’t generally have the power to run them efficiently.

The idea behind variable voltage / variable wattage devices is that you can adjust the power input for the resistance of the coil you are using to create your ideal vapour with any chosen e-liquid.

Two Basic Types of Variable Power Vaporizers

Variable Voltage

Variable voltage devices were the first on the market, and also tend to be used on smaller ‘pen’ devices. As you adjust the voltage, the wattage is automatically adjusted too, giving you more or less power to your heater coil.

These devices give you much more control than fixed power devices and are quite simple to operate.

Variable Voltage / Wattage

Larger, more expensive vaporizers have both variable voltage and variable wattage settings, giving you total control over the vapour you produce.

The basic settings are founded in Ohms Law, which is the following calculation;

(Voltage x Voltage) / Ohms(Coil Resistance) = Watts (Power)

Each atomizer coil will have a different heater resistance, usually anywhere from 1.8 ohms to 3.0 ohms. Variable devices with LCD display screens will have a setting which displays the resistance of the attached atomizer.

This handy Ohm Law Calculator will give you the settings you need, just enter your ohms resistance and it will tell you the corresponding wattage you need.

Once you know your resistance, you have a starting point to work from to find your perfect vape for the e-liquid you are using:

Whatever variable power vaporizer device you are using, the green/blue area in the chart above is the area you should be set at to achieve a great tasting vape without burning out your heater coil.

As an example, if your atomizer has a resistance of 2.1 ohms, your sweet spot will be using between 3 and 4.2 volts and 4.2 – 8.4 watts, in the combinations indicated in the chart above. In this example, you will get a different strength and taste of vape from a 3.0v /4.29 watt setting than you will from a 4.2v/ 8.4 watt setting.

My preferred vaping device at the moment is an Innokin iTaste MVP 2 Vaporizer which has variable voltage from 3.3v – 5v and variable wattage from 6w – 11w (Using a 2.1 ohm atomizer). Based on the chart above, the sweet spot for this device is therefore from 3.6v/6 watt up to 4.2v/8.5watt.

As I said above, with so many different flavour and strength combinations of e-liquid available and with everyone’s taste being different, you will need to try a few different settings to find the ideal power settings for you.

Personally, I have several different atomizers that I use with different e-liquid mixes depending on the time of day. Each one needs a different setting because they are in different resistance atomizers, the liquids react to heat differently and some, (especially subtler flavours ) need to be warmed rather than nuked to get the best out of them!

As long as you stay out of the red range on the chart, you can’t go wrong with your settings.
