Hearing crackling while vaping? This is a completely normal phenomenon, and we will explain why it occurs.

Why does my e-cigarette crackle?

This is a normal phenomenon caused by a temperature rise in the resistance coil. Under the influence of heat, the e-liquid contained in the wick reaches its boiling point, causing the characteristic crackling sound.

Don’t panic, everything is normal

When you activate an e-cigarette, it is very common for it to start crackling. This is a normal reaction. The solution of propylene glycol, the vegetable glycerin that makes up most of the e-liquid, has a boiling point of 185°. Therefore, when the resistance coil is first heated, its temperature rises very quickly and can cause the e-liquid to boil quickly.

Rebuildable atomizer enthusiasts know this phenomenon well. In fact, when building your own resistance coil and inserting a cotton wick, once the cotton wick is soaked in e-liquid, it is common to activate the battery to check that the setup is correct. At this point, a crackling sound will be heard and liquid or vapor ejections can be easily observed. This is also a great opportunity for macro photography enthusiasts to get some amazing shots.

In summary, if your e-cigarette crackles, it confirms that current is flowing through the resistance coil and that the wick is adequately supplied with liquid. However, if the crackling is too intense or too fast, it could mean that the battery setting is not compatible with the resistance coil. In this case, check that the settings are properly adjusted for your resistance coil.

Is it a problem if my e-cigarette doesn’t crackle?

Not all resistance coils crackle a lot. Although this phenomenon is very common, the absence of crackling does not mean that the setting is incorrect or that the device is defective. Some e-cigarettes are actually very discreet and virtually silent when in use.

Ultimately, a crackling resistance coil is a somewhat positive sign. Everything is normal!
