Coils in electronic cigarettes (e-cigarettes) are heating elements responsible for vaporizing e-liquid to create inhalable aerosol.
Types of Coils
- Kanthal: A widely used alloy of iron, chromium, and aluminum, known for its durability and resistance to oxidation.
- Nichrome: An alloy of nickel and chromium, heats up faster than Kanthal but may produce a metallic taste for some users.
- Stainless Steel: Offers a clean taste and can be used in both wattage and temperature control modes.
- Nickel: Primarily used in temperature control vaping due to its predictable resistance changes with temperature.
- Titanium: Another option for temperature control vaping, known for its rapid heating.
Coil Resistance
Coil resistance, measured in ohms (Ω), affects vapor production and flavor. Lower resistance coils (sub-ohm) produce more vapor and intense flavor, while higher resistance coils offer a more restricted draw and conserve e-liquid.
Coil Materials and Construction
Coils are typically constructed with a resistance wire wrapped around a wicking material, such as cotton, which absorbs the e-liquid. Proper wicking ensures consistent vapor production and prevents dry hits.
Coil Maintenance
Regular coil maintenance includes priming new coils, cleaning them periodically, and replacing them when vapor production decreases or flavor diminishes. Lifespan varies based on usage and e-liquid type.
Coil Safety
Using the correct coil type and resistance for your device is crucial for safety. Always follow manufacturer guidelines and avoid exceeding the recommended wattage range.
