What are Ohms?

An ohm is a unit of resistance. Essentially, the lower the resistance of your atomiser, the more electricity will flow through it. Increase the amount of resistance and less electricity will flow through. So when you use a lower resistance atomiser, and more electricity flows through, you will find the following:

  • More heat is generated at the coil
  • More vapour is generated
  • You may experience a more intense flavour (however, flavours perform differently with different resistance coils)
  • Vapour will be warmer

Depending on your tastes, the above may all be positives! On the negative side:

  • Your battery will be drained more quickly
  • Battery life may be reduced
  • E-Juice will be used more quickly
  • Coil life will be reduced (very low ohm atomisers may only last 2-3 days)
  • You are more likely to experience a dry hit (although recent innovations such as mesh coils and plexus coils help address this)

Obviously, when you use a high resistance coil the opposite will happen:

  • Less electricity flow
  • Creating a reduced coil heat
  • Reduced amount of vapour
  • Cooler vapour
  • You may experience a less intense flavour

But on the plus side:

  • Battery life will be longer
  • Less e-liquid will be used
  • You will be less likely to get a dry hit
