just try e-cigs now

Have you just bought an electronic cigarette? To know what watt to set your electronic cigarette, it is important to first know its mode of operation. The electronic cigarette, e-cigarette or vape, is a device used to produce vapour by gently heating a resistance surrounded by cotton without any combustion and then vaporizing the flavoured liquid called e-liquid. To consume this liquid transformed into vapour, it must be inhaled like tobacco smoke from a cigarette. To choose the setting of your electronic cigarette, it may be interesting to understand what a resistance value in ohm is, and more specifically better understand ohm’s law. Whether you have a Geekvape, Smok, Innokin, Vaporesso or even Eleaf electronic cigarette, know that the settings will be identical because all vapers work with the same principle.

If at the beginning of the vape, the vapers spoke more in terms of volt adjustment, today it is very simple to find the best wattage for your electronic cigarette. Indeed the mods and box, now equipped with a screen and secure software, allow the handling of the material of vape without great difficulty. But for that some knowledge is necessary, and we are here to help you, and lift the veil on the watt setting of your e-cigarette.

The electronic cigarette is generally composed of three main parts, which are:

  • The battery, which is the part producing the current to heat the resistor soaked in liquid. It has a main button called ” switch “, “Fire” or even “power” button, which triggers the current supplied to the resistance when pressure is exerted on it.
  • The clearomizer or atomizer: the “reservoir” part where the resistance is housed, as well as the liquid. You can then choose to vape a nicotine e-liquid or to use your electronic cigarette without nicotine. A central chimney directs the steam from the resistance to the drip tip to allow inhalation.
  • The resistance: this is the part that will transform the e-liquid into vapour. It is made up of a resistive wire that will heat, and cotton that will soak up the liquid.

These components of the electronic cigarette, as well as their roles, are all important to ensure its proper functioning.

How a resistor works

The resistance is the most important part that constitutes the electronic cigarette. Its main role is to turn e-liquid into vapour. It is made up of two different elements: the first is the resistive wire of the kanthal, nickel, stainless steel or even titanium type presented in the form of a wire or metal strip (mesh). 

If Ohm’s law, U (voltage in Volt ) = R (resistance in Ohm ) x I (current in Ampere), is intrinsically linked to the use of an electronic cigarette, you will however not need the know by heart (excluding the use of a fully mechanical mod ). 

The main modes of operation of an e-cigarette:

  • Variation in power/wattage (VW):
  • Temperature control (TC)
  • Semi-regulated mechanical mode or Bypass

Once the value of the resistance is known, it is then possible to determine the power setting of the electronic cigarette. For resistance:

  • Greater than 1.5 ohms: power less than 10 Watts
  • 1 ohm – 1.5 ohm: 9 to 15 watts
  • 0.5 ohm – 1 ohm: 20 to 35 watts
  • 0.3 – 0.5 ohm: 20 to 60 watts
  • 0.15 – 0.3 ohm: 20 to 100 watts

These are indicative values, it will always be more advisable to follow the power range in watts indicated on the resistance of your vape.

When we talk about adjusting the resistance of an electronic cigarette, we are mainly talking about the importance of having a power adapted to the value of the resistance installed. Knowing the right settings for your electronic cigarette is very useful, and will save you some problems (like the burnt taste). To properly adjust your electronic cigarette, it will be enough to know the value of its resistance and to follow the recommended power range in watts. However, the choice of resistance should not be trivial, it is essential to always opt for a model that adapts to the electronic cigarette. To do this, find the name of the model of your clearomiser and look for it on our online site! You can then find the resistance model you need
