All About Resistance

Back in the very early days of vaping when the first custom modified e-cigs (Mods) became available, they were all mechanical (without circuitry) and there were no rebuildable atomisers. The only way to control the vape was by adjusting the resistance of the atomiser coil. We were pioneers in commissioning custom resistance atomisers to enable vapers to tailor their vaping experience to provide the best flavour, heat, vapour and throat-hit for their own personal vaping style.

This post used to explain the different types of atomisers we'd customised to our specifications, but has now been updated due to technological changes and the introduction of more advanced devices which can control the voltage and wattage of your device.

Briefly:
With a mechanical device, the lower the resistance, the hotter the vape, and the quicker the juice (and the battery) is used. We now advise against the use of mechanical devices. See Safety Information.

When a modern variable wattage device is used, the device adjusts the voltage, based on the wattage you choose and the resistance of the atomiser.
Anything from 0.5-2.0Ω is suitable for most variable wattage devices these days, with many devices accepting much lower resistance coils for sub-ohm vaping. There are also speciality coils for temperature controlled vaping.

Each coil usually has a different power (wattage) recommendation, based upon its resistance, the size of the air hole and liquid feed-rate.

Sub-ohm atomisers

The use of very low resistance atomisers is often referred to as "sub-ohming", because the atomisers and coils used are much lower than 1.0Ω.

This is not to be confused with temperature control, where the coil resistances are typically sub-ohm, but not operating in a true sub-ohm fashion.

If you wish to use sub-ohm devices, you must make sure the battery you are using is capable of supporting the required discharge rate, and that your device features enhanced safety circuitry.

NEVER  sub-ohm on an unregulated or mechanical device. See Safety Information.
