I’m not getting any draw from my vaping device

Try the following:

Make sure your battery is switched on and has enough charge.
Check that you have e-liquid in your tank.
Make sure that there is a clean connection between your pod/tank and your vape battery device.
 

If none of that worked:

The odd coil can be a dud - even if it’s fresh out of the pack and properly primed. Sometimes the cotton can get too tightly wound within the coil which means no airflow can get through to give you the draw you’re used to. Change the coil for a new one, and let us know about the faulty coil so that we can replace it for you.
