There are several reasons why your device is not making any vapour. Check the list below to see if any of these may be a solution.
Some devices provide adjustable airflow, allowing you to customize the style of inhale from your device. If the airflow is closed off, it will not allow air to pass through the coil, meaning that no vapour will be created.
If the airflow is open, the next thing to check is the coil. If it has been used for longer than two weeks, it is recommended that you replace it. A burnt or clogged coil may obstruct the airflow of your tank, making significantly less vapour than a fresh one.
If the coil is not the problem, you’ll want to take a look at your battery. The battery must be turned on to function, and must be charged to create optimal vapour. As the battery loses charge, it will often become weaker, creating less vapour.
