My Vape Crackles – Should I Panic? 

You may have noticed your vape device making a crackling sound. The first thing to say is don't panic! Vapes can often make crackling, spitting, or popping noises. More often than not, it is completely normal and nothing to be concerned about.

After a while, you will become used to your vape's natural crackling noise or popping sounds. This will make it easier for you to listen out for more concerning sounds or potential problems.

This article will take you through everything you need to know about the noises your vape or e-cig makes. We will also answer the all-important question, why does my vape crackle?

Why Does My Vape Crackle?

Vape crackling and popping are caused by the device creating vapour. The process of inhaling causes the vape juice to be drawn to the coil. The vape coil heats up your e-liquid and vapourises it. It is this rapid heating that causes the crackling or popping noise that your vape makes.

E-Liquid

E-liquids can also impact the sound your vape makes when it is in use. The PG:VG ratio will typically make a difference. VG stands for Vegetable Glycerine, while PG refers to Propylene Glycol, two of the main ingredients in e-liquids. 

A ratio with a higher VG quantity will produce thicker clouds and a smoother hit. Higher PG ratios provide a stronger flavour and stronger hit.

Higher PG ratios also produce thinner liquids. This can result in a louder popping sound. Stronger VG ratios create a thicker vape juice and aren't as loud. However, they can still produce noise when being used.

Vape Coils

Vape coils can make a difference to the sounds your vape device makes. There are a number of different coil types available, and choosing a mesh coil might result in a louder crackling and popping sound.

Mesh coils are designed to heat e-liquid more evenly at a faster rate. This can result in louder noises when using your vape.

You may notice a more prominent sound if you have a newer device or have recently replaced your coil. This tends to settle down as the coil is used more.

Vape Power Output

The power output of your vape device will also impact the sound it makes. High-powered devices are able to heat the e-liquid at a greater rate, which can lead to noises. MTL devices will typically have a lower output. This results in a quieter device.

However, if the power output on your vape device is too low, it may result in a gurgling sound. Vaping with your power too low can cause a build-up of excess e-liquid. The coil head build-up can result in spitting. Flicking the device to remove any build-up or turning the power up can help.

Is it Okay if my Vape Crackles?

Slight crackling noises are perfectly ok. Many people new to vaping will ask the question, "why does my vape crackle?". As you get used to your new vape tank, you will also get used to the noises it makes.

Your vape crackling is a sign that the vape juice is being heated. This is necessary for producing the vapour you breathe in.

Thinner vape juice might make a bit more noise, but you shouldn't worry about that. Thicker liquid goes through the same process but can dampen the sounds more easily.

Is Vape Spitback Normal?

Vape spit-back can be a bit scary the first time it happens. Spit back, or spitting, is caused by a flooded coil. Too much e-liquid around the coil can result in droplets of hot liquid being spat out of the electrical device.

Hot liquid spitting into your face can be uncomfortable for the vaper. The areas most typically affected would be the tongue or lips and it can cause temporary numbness.

Old coils that need to be replaced can often cause spitting on their way out. This is because the wick gets saturated over time. The e-juice may also begin to get caramelised because of the heat and hot sugary liquids. This means the coils can't take on any more e-liquid, resulting in spitting.

Priming your coil prior to use can also do this. Priming coils is the process of exposing the coil to e-liquid before use.

This means it can be used more quickly after installation. It can also result in e-liquid coming into contact with the coil's heating element.

How do I Fix Vape Spitback?

Being very careful when priming your coil can help. Gently brushing the cotton with a small amount of liquid should be enough. You should also allow at least five minutes before starting to use your vape.

If spit back does occur, there are a few techniques to resolve the issue. Flicking the vape down onto a paper towel can help to dislodge and remove excess e-liquid.

Furthermore, ensuring your coil is clean is a great way to avoid spitting. Dabbing the coil with a cotton bud can help to soak up excess vape juice.

Are there any Vapes Which don't Crackle or Spit?

Low-powered MTL vape devices won't make as much noise as more powerful options. This is because the vape juice is heated at a lower temperature and doesn't vaporise as quickly. Draw-activated vapes are significantly less likely to spit or crackle. 

Moreover, an angled drip tip vape can also help to prevent spitting. A drip-tip vape is angled to prevent spitting from shooting towards your mouth. While it doesn't completely eradicate spitting, it does remove the risk attached to it.

No matter what vaping device you choose, there is still a risk of crackling or spitting. The vape's power output, coil resistance, and using more vape juice than is necessary can all make a difference, so being aware of these factors is key to reducing the risk of spitting and crackling. 

Conclusion

The most important thing anyone will learn on their vaping journey is when something has gone wrong. Many sounds that your vape makes can be considered good sounds. This is because they are proving that your vape is working as it should.

A hot coil should make a noise when heating up your e-juice. As the heat increases, so should the noise. However, if you notice your vape spitting a lot or producing a burnt flavour, it could be time to change your coil.

If you are a new vaper, you should understand that you don't need to know everything immediately. Experience is a great thing, and the more you vape, the better understanding you will have.

Comparing your device's noise against other people's can also be a mistake. You won't always know the resistance or wattage they are using. Even if they use the same device, they may have different settings or e-juices. So, if your vape is crackling more than your friend’s, that doesn’t necessarily mean something is wrong. 

In summary, a noisy vaping device does not always mean bad news. If you hear a bit of crackling, it is not the end of the world. More often than not, it just means the vape is working.
