What Are Coils?

Coils and Atomizers for Vapes

If you’re new to vaping or just want to understand how your e-cigarette works, you’ve probably come across the term coils. But what exactly is a coil, and what role does it play in your vaping experience? In this guide, we’ll cover everything you need to know.

What Are Coils?


Coils, also known as atomizers, are a crucial part of any e-cigarette. They consist of a small metal wire wrapped around a wick, usually made of cotton. When the battery is activated, the coil heats up, warming the wick that’s soaked in e-liquid. This process turns the e-liquid into vapor, which you then inhale.

How Do Coils Work?
Coils operate through a simple but effective process:

  1. Activation: When you take a puff or press a button, electricity flows from the battery to the coil.

  2. Heating: The metal wire in the coil heats up. The temperature depends on the type of coil and the materials used.

  3. Vaporization: The heated coil warms the wick, vaporizing the e-liquid.

  4. Inhalation: You inhale the vapor through the mouthpiece of your e-cigarette.

Types of Coils
There are several types of coils, each affecting flavor and vapor production differently:

  • Standard Coils: Simple coils with a single wire wrapped around a wick. Easy to use and replace.

  • Sub-ohm Coils: Coils with low resistance (<1 ohm) that produce more vapor and stronger flavor. Usually paired with more powerful batteries.

  • Mesh Coils: Made of a mesh material instead of traditional wire. They provide more even heating, better flavor, and longer lifespan.

  • Ceramic Coils: Use ceramic material instead of cotton, offering cleaner flavor and extended durability.

When Should You Replace Your Coil?


The lifespan of a coil depends on usage, e-liquid type, and coil design. Common signs it’s time for a replacement include:

  • Burnt Taste: The vapor tastes burnt.

  • Reduced Vapor Production: Less vapor than usual.

  • Leaks: Your device starts leaking e-liquid, often due to a worn coil.

Most coils need replacing every 2–4 weeks, but this varies depending on usage and e-liquid.

Tips for Extending Coil Lifespan

  • Prime Your Coil: Soak the wick with e-liquid before first use to prevent burning.

  • Use the Right E-Liquid: High VG liquids or heavily sweetened e-liquids can wear out coils faster. Choose e-liquids compatible with your device.

  • Avoid Dry Hits: Make sure the wick is always properly saturated with e-liquid to prevent damage.

Summary


Coils are an essential part of your e-cigarette, influencing both flavor and vapor output. By understanding how they work, the types available, and how to maintain them, you can improve your overall vaping experience.
