Why Does My Vape Pop and Crackle? Top 4 Causes and Fixes

Whenever one vapes, they might hear some popping or crackling sounds coming from their vaping device. This usually happens when the coil heats the vape juice and turns it into vapor.

The noise is even louder for people who take longer and more intense puffs while vaping. In case you’re still new to vaping, you might find these sounds rather strange.

You might be wondering if it’s something you should be worried about. While the popping sounds are normal, it might get to a point where the sound produced is a bit different from what you’re accustomed to hearing from your device.

This might mean that there’s an issue with your vaping device that needs some checking and subsequent fixing. Before you get to fix the issue however, you might be interested in learning what causes the pop and crackling sound.

Here are some likely reasons why you’re hearing these sounds, as well as some solutions to the problem. 

4 Top Reasons Why Your Vape Pops and Crackles

1. Low Wattage Setting

Whenever you take a puff, some air gets into the tank and the vape juice is brought by the wick to the coil. Once this is done, the coil heats up and vaporizes the e-juice.

If your wattage setting is low, the coil will fail to effectively vaporize the e-liquid or will take a longer time to do so. If this e-liquid does not completely vaporize, it will end up flooding your atomizer.

This will lead to crackling and popping noises. To avoid this, you could raise the wattage on your e-cigarette so that your vape juice is vaporized without causing any flooding in your coil.

You could also avoid the popping and crackling sounds by adjusting the airflow so that the amount of vape juice is reduced. If you’re using a sub-ohm tank, twist the tank’s collar so that some of the air pressure gets lost in the process.

2. Using a Thin Type of E-Liquid

The e-liquid you go for could also cause these popping sounds especially if it’s thin. Thin liquids are also known to cause flooding in your atomizer.

The popping will happen once your vape juice hits the already hot coils and the vapor is then created. E-liquids that contain PG are thinner and as such, they vaporize at lower temperatures.

To avoid these sounds, consider thicker e-liquids or those that contain higher VG rather than PG. They not only create more vapor but also consistently vaporize with the vaping pen you are using.

Another way to avoid it is to take shorter inhales as opposed to longer ones. Longer inhales will make you take in more vape juice than your vape pen can handle.

3. Using a Twisted or Braided Coil

If you’re using a twisted or braided coil, that means your vape juice will have more crevices and space to cover for it to vaporize. This increase in surface area will lead to the creation of more vapor but will also lead to more crackling and popping sounds.

While this can’t exactly be prevented once you already have the coil, you might want to consider this effect before and when you buy your e-cigarette device.

If you make your coils by yourself, you could do tighter twists to avoid having the liquid going into the crevices. This will stop the sounds.

Another way of preventing popping and crackling sounds when it comes to your coil is to avoid overpriming it. Don’t drip too much vape juice on the wick when you’re priming your coil.

Remember, it should be wet but not flooded. In case you soaked it too much by accident, just press the fire button before you start to inhale to fix the popping noises.

4. Using a Narrow Drip or Chimney

A narrow drip tip or chimney could also cause crackling sounds. That is because the vapor produced will condense inside them, causing the formation of droplets that will block the flow of air.

You can, therefore, avoid the popping sounds by going for a wider chimney or wide bore drip. This is because with wider ones, no extra vapor will condense and collect around the drip tip.

You could also consider using a rebuildable tank atomizer (RTA) which is known to have a wider chimney.

Moreover, there’s a new type of drip tip that can stop the spitback from getting to your mouth. These are usually angled, rotatable, bent, or curved ones with drip tips that are longer.

If after doing this you still hear the irritating sounds, try covering your drip tip. You can do this using a paper towel piece or placing a pipe screen that has been cut down on the inside part of the drip tip.

Wrap Up

You should appreciate the slight popping sound in case you are a newbie vaper as it is a normal part of the vaping experience.

However, in case you’ve been noticing that irritating type of crackling or popping, then these points in our article can help you understand the causes and might give you some solutions to the problem.

Always check if your vaping device is in need of fixing and do just that. Remember, it is always better to remain aware of any changes, slight or big when it comes to your e-cigarette.

Although very few, there have been cases of vape pens exploding but they were mostly related to defects in the battery that the user couldn’t have noticed as there’s almost no alert for them—not even popping sounds.

That said, if your vaporizer is producing no noise and is overheating, you might want to stop vaping immediately as it could lead to an explosion.

As you can see, most of the factors that cause normal popping or crackling sounds are related to the vape juice and coil wire interactions. If the sounds were not there in the first place, that could mean your device isn’t functioning properly.
