How to Build the Perfect Coil: A Comprehensive Guide for Experienced Vapers


For experienced vapers, there’s a level of satisfaction in crafting your coils that goes beyond the convenience of pre-made ones. Building your coils allows you to tailor your vaping experience precisely to your preferences, from flavor and vapor production to coil resistance. In this comprehensive guide, we’ll walk you through step-by-step instructions on how to build and install the perfect coil for your vape device.

Understanding Coil Building

Before we dive into the specifics of coil building, let’s cover some essential terms and concepts:

1. Coil:

  • A wire that heats up when an electrical current flows through it, vaporizing the e-liquid.

2. Resistance:

  • Measured in ohms (Ω), resistance determines the amount of power required to heat the coil.

3. Wire Types:

  • Various types of wires are used for coil building, including Kanthal, stainless steel, nichrome, and more.

4. Coil Jig:

  • A tool used to wrap the wire into consistent and evenly spaced coils.

5. Wick:

  • The material, usually organic cotton, that absorbs and delivers e-liquid to the coil.

6. Ohm’s Law:

  • A fundamental equation that relates voltage, current, and resistance in electrical circuits.

Step 1: Gather Your Supplies

Before you begin building your coil, ensure you have the following supplies ready:

  • Wire of your choice
  • Coil jig or screwdriver
  • Organic cotton
  • Tweezers
  • Scissors
  • Ohm meter or a regulated mod with resistance reading

Step 2: Choose Your Wire

  • Select the wire material and gauge (thickness) based on your desired coil resistance and vaping style. Thicker wire has lower resistance.

Step 3: Calculate Coil Resistance

  • Use Ohm’s Law (V = I × R) to calculate the coil’s resistance. Determine the voltage (usually your mod’s output voltage) and desired current (typically 20-30 amps for safe vaping). Solve for resistance (R).

Step 4: Wrap Your Coil

  • Attach one end of the wire to the coil jig or screwdriver. Wrap the wire around the jig the desired number of times, keeping the coils evenly spaced.

Step 5: Check Coil Resistance

  • Use an ohm meter or a regulated mod to check the resistance of your coil. Ensure it matches your calculated resistance.

Step 6: Install Your Coil

  • Insert the coil into your RDA (Rebuildable Dripping Atomizer) or RTA (Rebuildable Tank Atomizer).
  • Secure the coil by tightening the screws or clamps, ensuring it’s positioned centrally.
  • Trim any excess wire.

Step 7: Pulse and Adjust

  • Attach the RDA or RTA to your mod.
  • Pulse the coil at low wattage to check for hot spots or uneven heating.
  • Use ceramic tweezers to strum the coils and eliminate hot spots.

Step 8: Wick Your Coil

  • Thread a piece of organic cotton through the coil, ensuring it’s snug but not too tight.
  • Trim excess cotton, leaving enough for the ends to touch the base of the RDA or RTA.

Step 9: Prime and Test

  • Drip a few drops of e-liquid onto the cotton to prime it.
  • Reassemble your atomizer and test fire the coil, starting at low wattage and gradually increasing until you reach your desired vaping experience.

Step 10: Fine-Tune Your Vape

  • Experiment with wattage settings to find your preferred vaping temperature and flavor production.

Tips for Coil Building Success

  • Always practice safety by ensuring your coil resistance is within the limits of your mod’s capabilities.
  • Experiment with different coil builds, materials, and gauges to discover your ideal setup.
  • Keep your workspace clean and organized to prevent misplacing small parts.


Building your coils is a rewarding aspect of vaping, allowing you to customize your experience and achieve the perfect vape. With practice and patience, you can master the art of coil building and enjoy a vaping experience that’s tailored to your preferences. Whether you’re chasing massive clouds or savoring intricate flavors, building the perfect coil opens up a world of vaping possibilities.
