e-Cig Volts Watts oHms Amps.

Understanding how e cigs work is more than simply the volts of your battery.

It’s about oHms, Watts, Amps AND Volts and how they react to your device.

The math can be confusing to some but it’s important to understand at least the basics.

Although we can cheat a bit by using charts.

ALL delivery system devices have oHm ratings

The formula’s are:

Watts = Volts X Volts / Ohms

Amps = Volts / Ohms

Here’s some in depth information already written-

http://en.wikipedia.org/wiki/Ohm’s_law

There are reasons one should understand the basics:

To know the correct resistance for your accessory delivery system purchase

To help find your sweet spot of vaping

To insure you don’t overpower and burn out the accessory device

Some general guidelines:

Power (watts) is the intensity of the vape. 6-8 watts is the “sweet spot” for most vapers

Current (amps) is what can burn out atomizers. 1.5 – 2.0 amps is fine. 2.0+ amps is risky

The lower the resistance of your device, the faster it will drain the battery

The lower the resistance- The lower the volts you should use

The higher the resistance- The higher the volts you can use

If using VV a good rule of thumb is to add resistance plus 2 volts then adjust up or down

So, with a 1.8 oHm Atty plus 2 volts = 3.8 volt setting

For a 3.7 volt device use 1.8 oHm resistance

Other useful information:

At an experiential level- LOWER OHMS:

Will run hotter producing a warmer vapor

Will create more vapor

Will produce more throat hit

Will affect the flavor produced either by producing more or diminishing it.

Will drain your battery faster

Will go through e-liquid a little faster which increases the likelihood of a dry hit if your e-cigarette can’t keep up with the rate of use

At an experiential level- HIGHER OHMS:

Will run a bit cooler producing a cooler vapor

Will create less vapor

Will produce a smoother vape with less throat hit

Will affect the flavor produced either amplifying or diminishing it depending on the individual flavor.

Will allow your battery to last longer between charges

Will use less e-liquid

Everyone has different tastes and expectations.

Some may look for a warmer vape, providing greater throat hit.

Some may want a milder all round experience.

At times we want the ability for both so it’s nice to have a couple of oHm variations with any given accessory.

When ordering a new system to try it’s best to get 2 variations.

If you’re ordering a Cartomizer you wish to try a 2oHm and a 1.8 oHm to see which one works best for you.

If you own multiple E-Cig devices you may find one suits one better.

You will get to know what you like by experimenting.

Here is an easy to follow Chart for those that don’t wish to use math:

3.7 Volt E Cigs:

Let’s look at an example from the chart above.

Follow the 3.75 volt column listed on top.

We can see that the safe resistance range is from 1.8 up to 3.5 oHms.

This may be true BUT on all 3.7 volt devices I’ve used, I find anything over 2 oHms produces insufficient levels of vapor and little satisfaction.

In some respects a 3.7 volt device is simpler to work with.

You are given a voltage limit.

Everyone has different tastes so it’s impossible to give a single set of numbers to abide by.

Various delivery systems also react slightly differently.

E Liquid viscosity is a factor too as Flavor/Taste alters at different outputs.

Sometimes e liquids taste better at 4.5 or 5 volts.

One important point regarding 3.7 Volt devices.

Lower oHms will provide a better vape, in general, but lower oHms reduce your battery life.

This is ONE of the primary reasons for owning a larger style E Cig.

Perhaps a Tube Mod or a variable voltage device.

They take much larger batteries and allow for all day vaping without the need to recharge.

Variable Voltage E Cigs:

Because we have a far greater range to work with, this also allows for greater flexibility in deciding what resistance to try.

Look at the column showing 4.75 Volts.

The safe resistance range is 2.8 – 5.0 oHms.

I would recommend trying various settings with a 3.0 oHm device.

A good rule for experimenting with resistances is to use an Atomizer.

This way you’re not spending a lot on a Tank system like a Kanger. Once you know what range you like you can order more expensive delivery systems.

If you already own something like a Vivi Nova or Kanger ProTank you can simply buy a few coils at various resistances to experiment with.

In general, for VV devices, I tend to stick with 3 oHm resistance.

But everyone needs to experiment to determine one’s preferences.
