The main difference between a lower Ohm/Ω coil versus a higher number is that less voltage is required for the lower Ohm. The lower Ohm coil is generally likely to heat faster, produce a warmer vapour and more of it. Use our blog link for more information about what are Ohms and an easy-to-understand explanation about electrical resistance and the advantages and disadvantages of your various options.

Sub-Ohm means less than 1.0 Ohm (1.0Ω).

Most sub-Ohm coils have the Ω written on them. It may say 0.5Ω, 0.2Ω, 0.5Ω, etc

How to prime your coils

‘Priming’ is essential to avoid a vile burnt taste and ruined coils.

e-Liquid for sub-Ohm vaping

Sub-Ohm coils generally require thicker e-liquid, that means more of the VG than PG. It’s the VG that produces more vapour and a smoother throat hit.

For sub-Ohm coils, the average is a 70-75% VG blend but it’s trial an error, sometimes a 50% VG will work well for you, for others it’s an 80% VG. It depends on your coils and your set-up and it depends on your personal preferences too.

Be aware that 6mg (0.6%) nicotine is often a maximum strength e-liquid to use in a sub-Ohm device. If you can’t take the hit from the increased vapour, turning the power down may cause more problems than it solves, instead you need to reduce the nicotine strength.

Safety Notice

Sub-Ohm tanks and coils must be used by experienced and knowledgeable users as additional safety precautions must be practiced when using these items. These products need to work on a mod/battery capable of firing at sub-Ohm resistances. So, for example, if you have a 0.5 Ohm coil in your tank, your mod/battery must be capable of firing at 0.5 Ohm resistance, or lower. You also need to ensure your device can cope with the amps. Improper use can lead to physical injury and damaged equipment.
