Why Your Disposable E-Cigarette Makes Crackling Sound

In the world of versatile disposable e-cigarettes, many users have experienced an interesting phenomenon – the sudden crackling sound. But have you ever wondered why your device makes that crackling sound? In this blog, we’ll delve deeper into the principles behind this auditory sensation and explore the factors that cause vape bars to make that crackling sound.

Disposable E-Cigarette

1. Ingredients of e-liquid

One of the main reasons for cracks in disposable e-cigarettes is the e-liquid content inside. E-liquids typically consist of a mixture of propylene glycol (PG) and vegetable glycerin (VG) along with flavorings and nicotine. When these liquids are heated by the coil in your vape, they convert into vapor, producing that familiar crackling sound. When the VG content of e-liquid is higher, the cracks will be more obvious because the VG tends to be thicker and create larger vapor clouds.

2. Coil design and materials

The coil is the main component of a disposable e-cigarette and is used to heat the e-liquid and convert it into vapor. The design and material of the coil are closely related to the occurrence of crack phenomena. Coils with a twisted or braided design tend to create more surface area for the e-liquid to interact, thus enhancing crack.Coils made of materials such as Kanthal or nichrome have unique thermal properties that can produce a hissing sound.

3. Airflow in Disposable E-Cigarette

The airflow in disposable e-cigarettes can also produce a crackling sound. When you inhale, air enters the device and reaches the coil. MirusVape products feature simple, effortless airflow control, allowing you to fine-tune your puff and customize the intensity of your puff with a simple twist or slide, turning each puff into a personalized mix of flavor and satisfaction . The interaction between the airflow and the heating coil creates a crackling sound that accompanies your satisfying vaping experience.

4. Moisture and condensation

The e-liquid undergoes a transition from liquid to vapor when you are vaping. This shift may lead to condensation within the device. The crackling sound you hear may be caused by the hissing sound from residual moisture on the coil. This phenomenon is more apparent after the disposable e-cigarette device has been idle for a period of time, and the accumulated condensation water will evaporate during the next puff.

5. Temperature control

Temperature control is a feature found on some vape disposables that allows users to set a specific temperature for their vaping experience. The operating temperature of the coil will also cause crackling sounds. Higher temperatures will cause more intense vaporization, resulting in more pronounced cracks.

6. Coil start-up and break-in

It is important to activate the coil correctly when you start using a disposable e-cigarette. The coil needs to be saturated with e-liquid before taking your first puff. During initial use, the coil of your vape will adjust to heat and airflow. The crackling sound may be more noticeable when the coil reaches peak performance.


In the world of flavored disposable vape kits, crackling sounds are the result of a complex interplay between e-liquid ingredients, coil design, airflow, humidity, temperature control, and coil break-in. Understanding these factors allows vapers to fine-tune their experience. So, the next time your e-cigarette device makes a crackling sound, know that it’s more than just a sound.
