A Guide to Variable Voltage/Variable Wattage E Cig Devices

what is variable wattage voltage ecigsIf you are reading this then you are either considering purchasing or have just purchased a VV/VW device. For vapers this is the big transition from a device that looks like a cigarette or a vape pen or eGo battery.

You are marking a stage where you are moving up from a starter kit to advanced vaping.

Why?

The reason people go for these types of devices is because they are seeking something more from their vaping experience.

Being able to change the voltage or wattage on your device means that you can increase/decrease the electrical current flowing through the coil. The benefits of this are improved flavour and vapour production.

When?

You may wish to try out different liquids containing different amounts of nicotine, different ratios of PG/VG, different flavours of e juice or using a different atomiser/resistance coil.

How?

By altering the flow of current through the coil will heat it differently. You will find a setting that works for you, one that produces the flavour and vape you find more satisfying than the fixed voltage from an Ego/vape pen style battery.

Watt?

An typical vape pen battery contains a 3.7 volt battery and most of the atomisers for it are around 1.5ohms.halo tank kit review

Using the equation known as Ohm’s Law V=I*R tells us that a maximum current of 2.5amps flows in this circuit.

Using the Power equation P=V*I tells us what energy is being provided to heating the eliquid, in this case 9.25 watts.

BUT as the battery is used the voltage will begin to drop. As it decreases so does the current flowing around the circuit and the energy getting to the coil.

Who?

So who uses a VV/VW device?

The short answer is people who want a consistent vape experience or more ‘oomph’ in their vape.IPV D3 Mod Review

The electronics contained within a VV/VW device will automatically adjust the voltage or the power to keep it at a constant level.

If you set your device for 4.2 volts the device will “step-up” the battery’s output as it begins to run down so that even if the battery would read 3.6volt the device will boost it to 4.2V.

This means a consistency of vape until the battery needs replacing with another.

Many people prefer to use the power setting and select the watts they want as this provides a more even delivery of energy to the coil and automatically adjusts itself for fluctuations in the battery’s output.

The answer here is to begin at a low setting and gradually increase to output until you reach one that is giving you the flavour and/or throat hit you desire.

The setting you choose can vary depending on the juice you are using and the resistance of the coil. Note that a lot of VV/VW devices will not operate if the resistance of the coil is too low. This offers a good safety function as it protects you and your device from a short circuit.

You will notice that there is a peak setting above which the coil gets too hot and evaporates the e-liquid so quickly the wick can not feed juice fast enough to the coil – this will give you a dry burn.

Again, by slowly dialling up the power you will avoid this problem and experience will quickly tell you the levels you are comfortable vaping at.

Equipment

As well as a VV/VW device you may also need to buy an 18-series battery or batteries. The larger the battery the longer it will last. The ‘18’ refers to its diameter; the 18350 battery is 350mm in height. The 18650 is larger at 650mm in height andCool Fire 4 TC18650 vape mod

The ‘18’ refers to its diameter; the 18350 battery is 350mm in height. The 18650 is larger at 650mm in height and will therefore, last longer. The 18650 battery is the most popular option.

If you go for the replaceable option then please be sure you know your vape battery safety! Check out our guide to batteries for sub ohm vaping if you go down this route.

Of course, if you don’t want to mess around with replacing batteries then you will want to go for a vape mod with an integrated battery.On Off button cool fire 4

Which Variable Wattage Device Should I Buy?

The range is so big you can afford to get something you think looks good but the rule of thumb will be that the cheaper it is the sooner it will probably need replacing…but then not everyone wants to spend £150 on a Provari when it does the same job as a £35 Vamo.

Some prefer the tubular mods but the most popular are without doubt box mods, for me, these are the easiest starting point for vapers.

Which is best – Voltage or Wattage?

Batteries do not give out a consistent voltage, it fluctuates up and down and most people favoured wattage settings, as this setting would compensate for the fluctuations.

So no matter what the resistance (oHm rating) of the coil in your tank/clearomizer, the device using variable wattage would adjust automatically.

Using the variable voltage setting would mean manual adjustments need to be made depending on the resistance of the coil.

Devices such as the Vamo now give you two options for voltage settings. The first is the raw, fluctuating voltage that some people find gives a harsher throat hit. The second setting is the RMS function that, without going into the maths, is like an average voltage smoothing out the fluctuations. This second setting gives a smoother vape.

So, what you will find is that it will come down to your personal preference. There is no right or wrong, just what works for you.

What do I need to look out for?

  1. Does it have a display?
  2. What readings does it show?
  3. What does it let me adjust?
  4. What are its operating limits?
  5. Does it work with the resistance of the atomizer,tank I am using?
  6. Do I really need those functions?
  7. Can I afford it?
  8. If something goes wrong can I return it to be fixed?
  9. Will I be covered by UK buyers protection?
