OHMs Vaping

If you're new to vaping, you may be wondering what is all the hassle about the clearomizer's ohms and resistance. Although it sounds confusing (more like a physic's formula!), they're essentially pretty easy to deal with. Let's get into it!

An ohm is a unit of resistance. Actually, 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. 

All coils generate heat that is driven by the battery. The heat turns your e-liquid into a vapour, but some coils create more heat than others. Why? It’s because atomizer coils with low electrical resistance (or lower ohm numbers) create more heat and a warmer vapour. Those with high resistance (or higher ohm numbers) produce a cooler vapour.

There isn't one particular ohm setting. The thing is, every person is different. When it comes to vaping, everyone develops their own favourite vaping set up and the best way to figure out what coil is best for you, you need to try them out, and keep trying until you figure out what you like the most.

How does different oHm set up affet your vape?

The ohm rating contributes to your throat hit as well as the amount of vapour your ecig produces. Keep in mind that those features are also determined by your battery’s input voltage as well as your e-liquid’s PG/VG e-liquid ratio.

A low ohm coil is between 1.5 – 1.8ohms; a standard ohm coil is generally between 2.4 – 2.8ohms; and high ohm is anything 3.0 ohms or more.

People who love an intense throat hit should choose the lower ohm resistance, but experimentation is the key since your vape depends on other factors too. 

Vaping on low oHm setting means:

  • Hotter vapour
  • Stronger throat hit
  • Your battery will lose it’s charge faster
  • You’ll burn up your e-liquid faster
  • You’ll get more unpleasant dry hits (because you run down your e-liquid faster)
  • Some flavours can taste better (or worse) depending on your e-juice

Vaping on higher oHm setting means:

  • Cooler vapour
  • You’ll get less of a throat hit
  • Your battery will hold it’s charge longer
  • Your e-liquid will last longer
  • Some flavours can taste weaker, but smoother depending on your e-juice

A good rule of thumb is that if you’re vaping with a lower battery input voltage (between 3.0 – 3.5) you can safely choose a lower ohm resistance.

On a standard eGo battery, the battery input voltage is usually between 3.3 and 3.7 volts so choose your atomizer’s ohms between (the very lowest) 1.5 and 3.4 ohms (the very highest).
