What is a Coil in a Vaping Device?

In a vaping device, the coil serves as the heating element responsible for vaporizing the liquid solution, commonly known as e-liquid or vape juice. The coil is typically made of a metal wire wrapped around a wicking material, often cotton, that absorbs the e-liquid.

When the device is activated, the battery heats the coil, which in turn heats the saturated wick, transforming the e-liquid into an inhalable vapor.

In a properly functioning device, the coil evenly distributes heat, maintaining a balance that prevents it from reaching excessively high temperatures.

However, with regular use, the coil can degrade, resulting in uneven heating. When the coil burns out, it can produce a range of potentially harmful substances that can adversely affect lung health.

Therefore, maintaining and regularly replacing the coil is crucial for minimizing health risks associated with vaping.

Burnt Coils vs. Regular Coils

Both burnt and regular coils serve the same fundamental purpose in a vaping device: to heat the e-liquid and produce vapor.

However, the state of the coil significantly impacts not only the vaping experience but also the potential health risks involved.

Regular Coils

A regular coil heats the e-liquid evenly, ensuring that it vaporizes at an optimal temperature.

This provides a smoother, more flavorful vaping experience and minimizes the production of harmful or toxic compounds.

Regular coils are generally clean, free from accumulated gunk, and not oxidized, ensuring that the vapor produced is as pure as possible given the constituents of the e-liquid.

Burnt Coils

On the other hand, burnt coils are coils that have degraded due to prolonged use, poor maintenance, or flawed design.

They can no longer heat the e-liquid evenly and may produce an unpleasant, burnt taste.

More importantly, burnt coils are more likely to produce harmful or even toxic chemicals, including formaldehyde, acetaldehyde, and acrolein, which can pose serious risks to lung health.

Signs That Your Coil is Burnt or Damaged

Knowing when your coil is burnt or damaged is crucial for maintaining a safer and more enjoyable vaping experience.

Here are some signs that your coil may need replacement:

  • Unpleasant Taste: One of the most immediate and noticeable signs of a burnt coil is a distinctly unpleasant, burnt taste when you inhale. This is different from the flavor of your e-liquid and is a strong indicator that the coil is degraded.
  • Reduced Vapor Production: A damaged or burnt coil often results in significantly reduced vapor production. If you notice that your device isn’t generating as much vapor as it usually does, the coil may be the culprit.
  • Gurgling Sounds: A well-functioning coil should not make any unusual noises. If you hear gurgling sounds while using your device, this could be a sign that the coil is flooded with e-liquid and is possibly damaged or burnt.
  • Leaking E-Liquid: A compromised coil can cause the device to leak e-liquid, as it may not be vaporizing the liquid effectively. If you notice persistent leaks despite ensuring that all parts are correctly assembled, it may be time to inspect the coil.
  • Weak or “Off” Flavors: If the flavor of your vapor seems weak or “off,” it could be due to a coil that is on its way to being burnt. The coil may no longer be effectively vaporizing the e-liquid, leading to a muted or altered taste.
  • Visual Inspection: A healthy coil should be relatively clean and free of residue. A burnt coil may appear dark, crusted, or visibly damaged upon inspection.
  • Frequent Dry Hits: If you experience dry hits more frequently than usual, your coil might be unable to wick the e-liquid properly, possibly because it’s burnt or damaged.
  • Older Coil: Coils have a limited lifespan, usually between one to three weeks, depending on usage. If you’ve been using the same coil for an extended period, it’s a good idea to replace it, even if you haven’t noticed any of the above signs.

Note: By paying attention to these indicators, you can proactively replace your coil before it becomes a potential health risk. Regular coil maintenance and replacement are essential for a safer vaping experience.
