A resistor, a wick or an atomizer head is a consumable of your electronic cigarette that will heat thanks to the power sent by your battery. When you press the switch (ignition button), the resistance increases in temperature and the liquid located in your tank heats up to produce steam. This resistance for electronic cigarettes is composed of a resistive wire (the metal part that will heat the liquid) as well as an organic cotton wick (the part soaked in liquid). It has a positive pole and a negative pole which will be traversed by an electric current.

There are several types of resistive wires,  resistors for electronic cigarettes or pre-made resistors available for tanks and drippers so that everyone can find what they are looking for. Resistance has a greater or lesser value in Ohms which will affect the sensations felt in terms of the flavours of liquids, the volume of vapour and the sensation in the throat after inhalation. This value in ohm will determine the power to apply and the nicotine level to set!


If you have a classic battery without variable voltage/wattage:  prefer resistances greater than 1.5 Ohm to produce a correct volume of vapour while keeping a maximum of flavours, even with a high rate of nicotine. You will not be able to use resistors with a value in Ohms that is too low, otherwise, your clearomizers or reconstructable atomizers will be damaged: the battery normally has protection, if the value of the resistor is less than 1.5 ohm your electronic cigarette will work not, for your safety.

If you have a variable voltage/wattage battery: To choose the right resistance for an electronic cigarette, you need to know the minimum resistance value accepted by your battery. This of course varies depending on the model. The lower your resistance to the clearomizer, the thicker and denser the vapour will be. But be careful because its lifespan may decrease. The flavours of liquids also tend to decrease when the resistors have a fairly low value in Ohms. 

If you have a MOD or an Electronic BOX: Like batteries with variable voltage or wattage, electronic mods or boxes have protection preventing the use of certain resistors. Some MODs and BOXes can nevertheless be used with resistors having a very low Ohm value (≥ 0.1 Ohm for example).

If you have a Mechanical MOD or BOX: Unlike regulated versions, mechanical MODs and BOXes do not have protection and therefore operate in principle with all the resistors. Be careful though, because it is the discharge current of your electronic cigarette battery that will determine the minimum value of your resistance. If you opt for the sub-ohm (resistances below 1 ohm) you must always favour batteries with the highest discharge current, for your safety and to avoid an unsuitable voltage. It is expressed in amperes. 


Batteries or electronic MODs generally all have electronic protection preventing the use of resistances that are too low, to avoid any damage to your equipment. Manufacturers have developed smart batteries that ensure a safe and efficient vape. Novice vapers will not hesitate to choose this type of material to enjoy a generous vapour without having to worry about the rest. The vape adapts to our users and that is without a shadow of a doubt what explains its success!

For mechanical MODs, be very careful about using low-value resistors. For your safety, it is imperative that you have a good understanding of Ohm’s Law and that you know the discharge current of your battery. In general, we do not recommend that you make or choose pre-mounted resistors lower than 0.5 Ohm. Devoid of any security, these batteries are reserved for experts looking for high power.


  • A low resistance (≤ 0.8 Ohm for example) will require more power (expressed in Watt)
  • A high resistance (≥ 1.5 Ohms) will require more Voltage (expressed in Volt)
  • Adjusting the voltage or wattage can affect the temperature of the vapour and therefore the flavours of your vape. 
  • The lower the resistance, the more you will stress the cotton and the resistive wire. The resistance will then have a more limited lifespan.

For example: with resistance for an electronic cigarette of 0.5 Ohm, you will have to provide a power of at least 15 Watts and go up to 30 Watts. Its voltage will then be relatively low. This power range will allow you to obtain a fairly dense vapour and perfect vaporization of the liquid. 

Example 2: with a resistance of 1.8 Ohms, you will have to supply a power of 15 Watts maximum and normal tension.

Example 3: with a resistance of 2.4 Ohms, you will have to supply a power of 10 Watts maximum. Its tension will then be relatively high.
