Introduction to Vape Coils
Vape coils are the heating elements inside your vaping device that vaporise e-liquid. They are the most frequently replaced component in any vaping setup and directly impact flavour, vapour production, and overall vaping satisfaction. This comprehensive guide explains everything Australian vapers need to know about vape coils including types, materials, lifespan, and when to replace them.
A vape coil consists of a resistance wire wrapped into a coil shape, surrounded by a wicking material (typically organic cotton) that absorbs e-liquid. When you press the fire button, electrical current heats the coil wire, which vaporises the e-liquid absorbed in the wicking material.
Types of Vape Coils
Pre-Built Stock Coils
Stock coils are factory-made coils designed for specific tank or pod systems. They are the most convenient option for beginners and everyday vapers. Simply screw the coil into your tank, prime it with e-liquid, and you are ready to vape. Stock coils come in various resistance levels and materials optimised for different vaping styles.
Rebuildable Coils
Rebuildable coils require you to install and wick the coil yourself using wire and cotton. These are used in rebuildable dripping atomisers (RDAs), rebuildable tank atomisers (RTAs), and rebuildable pod systems. Rebuildable coils offer greater customisation, lower running costs over time, and the ability to tailor your vaping experience precisely.
Coil Materials Explained
Kanthal (FeCrAl): The most common coil material. Kanthal is durable, affordable, and compatible with all vaping modes including wattage mode. It has a higher resistance compared to other materials and is ideal for beginners learning to build coils.
Nichrome (Ni80): Nichrome heats up faster than Kanthal and has lower resistance for the same build. It provides a slightly cleaner flavour profile and is popular among flavour chasers. Nichrome is suitable for wattage mode and temperature control mode on compatible devices.
Stainless Steel (SS316L): The most versatile coil material. Stainless steel can be used in wattage mode, temperature control mode, and variable temperature control (VTC) mode. It delivers excellent flavour and has a clean, neutral taste. SS316 is also the safest option for temperature control vaping.
Nickel (Ni200): Used exclusively for temperature control vaping. Nickel coils cannot be used in wattage mode as they can release toxic compounds when overheated. Rarely used in modern pre-built coils.
Titanium (Ti): Similar to nickel, titanium is only suitable for temperature control vaping. It requires careful handling as titanium oxide can form at high temperatures.
Coil Resistance and What It Means
Coil resistance measured in ohms directly affects your vaping experience. Sub-ohm coils (below 1.0 ohm) are designed for direct-to-lung vaping with high wattage, producing large vapour clouds and intense flavour. They require more battery power and e-liquid consumption. Above-ohm coils (1.0 ohm or higher) are designed for mouth-to-lung vaping with lower wattage, mimicking the draw of a traditional cigarette. They use less e-liquid and battery power.
How Long Do Vape Coils Last?
The lifespan of a vape coil depends on several factors: frequency of use, e-liquid composition (high VG and sweeteners reduce coil life), vaping wattage, and maintenance practices. On average, a stock coil lasts 1 to 3 weeks depending on usage. Rebuildable coils can last longer as the cotton can be replaced without replacing the wire.
Signs that a coil needs replacing include: burnt or metallic taste, significantly reduced vapour production, gurgling or spitting sounds, leaking from the airflow holes, and dark, discoloured e-liquid in the tank.
How to Extend Coil Life
Properly prime new coils by applying e-liquid directly to the cotton wicking ports before installation, then fill the tank and let it sit for 5 to 10 minutes before vaping. Start at a lower wattage and gradually increase to your preferred setting. Avoid chain vaping, which can dry out the wicking material before it can re-saturate. Use e-liquids with less added sweetener. Clean your tank regularly when changing coils.
Choosing the Right Coil for Your Device
Check your device user manual for compatible coil types and recommended wattage ranges. Beginners should start with stock coils in the middle of the recommended resistance range. Advanced users may prefer rebuildable options for greater control. Consider your vaping style: mouth-to-lung vapers need higher resistance coils, while direct-to-lung vapers prefer sub-ohm options.
Coil Safety Tips
Never fire a coil dry (without e-liquid in the wick), as this can produce harmful compounds. Check that your coil resistance is within the safe operating range of your device. Replace coils immediately if you notice a persistent burnt taste. Do not use damaged or deformed coils. For rebuildable coils, ensure your wire wraps do not touch each other to prevent hot spots.
Australian Availability
Vape coils and accessories are widely available from Australian vape retailers and online stores. Nicotine-containing products require a prescription. Zero-nicotine coils and devices are available without restrictions for adult purchasers.
Frequently Asked Questions
Can I clean and reuse vape coils?
While some vapers attempt to clean stock coils by soaking in alcohol or boiling water, this is not recommended as it can damage the wicking material and affect flavour. Stock coils are designed for single use and should be replaced when worn.
Why does my coil taste burnt after one day?
This usually indicates improper priming, chain vaping, or using a coil at too high a wattage. Try priming more thoroughly and reducing your wattage.
Are ceramic coils better than cotton coils?
Ceramic coils offer different characteristics including longer lifespan and cleaner flavour, but they are less common and compatible only with specific devices.
Summary
Understanding vape coils is essential for getting the best performance from your device. Choose the right coil type and material for your vaping style, maintain it properly, and replace it when you notice degradation in flavour or vapour production.
