What is the difference between ohm’s for cartomizers and tanks?


The ohm rating of a tank or cartomizer tells you two things; how tight or airy the draw will be and how much heat the coil can handle before burning (for those using adjustable voltage batteries or MOD units).

If you are using a Mystart battery, which cannot adjust voltage, the ohms of a tank will tell you what type of draw and vapor production to expect. Below are a few examples for different ohms.

1.8 ohm- Lower resistance allows more air flow and thus produces an easy draw with an airy pull and high vapor production.

2.4 ohm- Tighter pull, similar to that of an actual cigarette with normal vapor production.

2.8 ohm- Higher resistance allows less air flow, producing a tighter pull with lower vapor production.

***Note- For maximum vapor production, we recommend using a dual coil tank or cartomizer. As their name suggests, these products contain two coils which are heating up to burn off e-liquid and produce vapor. Although they do drain battery life faster, for vapers looking for a heavy hit, dual coil products are a staple e-cig tool.


For vapers using batteries with an adjustable voltage feature, such as the Mystart Revolvers, the ohms of a tank or cartomizer will also tell you what the ideal voltage is to use for that product. To get the maximum lifespan from your cartomizers and tanks, we recommend using the voltages below:

1.7 ohm- 3.3 to 4.0 volts

2.0 ohm- 3.7 to 4.2 volts

2.4 ohm- 3.7 to 4.5 volts

2.8 ohm- 3.7 to 4.5 volts

3.2 ohm- 4.2 to 5.0 volts

4.0 ohm- 4.5 to 5.5 volts

4.5 ohm- 5.0 to 6.0 volts

5.0 ohm- 6.0 to 7.4 volts


*1.6 ohm, dual coil- 3.7 to 5.0 volts- For maximum vapor production, these tanks or cartomizers can be run at the highest voltage setting on Revolver batteries, 4.8 volts.

 Running at the correct voltage will help extend the lifespan of your coils, tanks and cartomizers and will help prevent burning issues. If you run above the recommended voltage, you may damage or destroy your tank/carto unintentionally or you may notice a prevalent burnt taste when vaping.
