Vape Crackling: Is it Normal or a Sign of Trouble?

Vaping has become quite a popular alternative to traditional smoking, thanks to its convenience and the various flavours available. However, as with any new technology, there are certain aspects of vaping that can cause confusion and concern. One of these is the crackling sound that often accompanies vaping. While some vapers may find the sound satisfying, others may wonder if it's a sign of trouble. In this article, we will explore the causes of vape crackling, whether it's normal or not, and what you can do about it. So, if you're a vaper who's curious about this phenomenon, keep reading to learn more.

What Causes Vape Crackling?

Before we dive into whether or not vape crackling is normal or a sign of trouble, let's first explore what causes it. Vape crackling is typically caused by e-liquid that is not vapourising properly. When you inhale on your vape, the coil inside heats up the e-liquid, turning it into vapour you inhale. If the coil is not heating the e-liquid evenly, or if there is too much e-liquid in the coil, it can cause the liquid to pop and crackle.

Another common cause of vape crackling is the presence of air bubbles in the e-liquid. When there are air bubbles in your vape, they can get trapped in the coil and cause the e-liquid to pop and crackle. Additionally, the type of e-liquid that you are using can also contribute to the crackling sound. E-liquids are vape products that have a higher VG content and tend to be thicker, which can make them more prone to crackling.

Is Vape Crackling Normal?

Now that we know what causes vape crackling let's explore whether or not it is normal. In short, yes, vape crackling is a normal occurrence. In fact, it is so common that many vapers consider it to be a sign that their device is working properly. As long as your vape is producing a consistent amount of vapour and you are not experiencing any other issues, there is no need to worry about the crackling sound.

However, there are some instances where vape crackling can be a sign of trouble. If your vape is producing an excessive amount of crackling or if the crackling is accompanied by a burnt taste, it could be an indication that your coil needs to be replaced. Over time, coils can become worn out and less efficient at vapourising e-liquid, which can lead to a host of issues, including crackling.

In some cases, vape crackling can also be a sign of a flooded coil. When there is too much e-liquid in the coil, it can cause the liquid to pop and crackle. If you suspect that your coil is flooded, you can try blowing through the mouthpiece to clear out any excess liquid.

Tips for Reducing Vape Crackling

If you find that the crackling sound from your vape is bothering you, there are some steps that you can take to reduce it. One of the easiest ways to reduce vape crackling is to adjust the wattage on your device. Lowering the wattage can help to prevent the e-liquid from vapourising too quickly, which can cause it to pop and crackle.

Another way to reduce vape crackling is to ensure that your coil is properly primed before use. Priming your coil involves saturating it with e-liquid before you start vaping. This helps to ensure that the coil is evenly coated with e-liquid, which can help to prevent crackling.

Lastly, choosing the right e-liquid can also help to reduce vape crackling. E-liquids that have a higher PG content tend to be thinner, which can make them less prone to crackling. Additionally, choosing an e-liquid with a lower nicotine content can also help to reduce crackling.


Vape crackling is a common occurrence that is typically nothing to worry about. While it can be a sign of trouble in some instances, it is usually just a sign that your device is working properly.
