If you’ve ever wondered what makes your vape device deliver rich vapour and flavour, it’s all thanks to the vape coil. These small but vital components are the powerhouse of any e-cigarette or pod system. At FREESMO.co.uk, we stock a wide range of vape coils for sale in the UK, suited for beginners and experienced vapers alike.
Understanding the inner mechanics of vape coils will help you choose the right type for your device and get the most out of every puff. This guide focuses on how vape coils work, the different types of coils, and which options best suit your vaping style.
A vape coil is a resistance wire wrapped in cotton, designed to heat up when your device is activated. This heat vaporises the e-liquid soaked into the wick, producing the vapour you inhale.
At FREESMO.co.uk, you’ll find trusted brands like VooPoo, Aspire, and Geekvape, offering coils with precision engineering for various vaping styles.
There are two main categories of vape coils:
Sub-ohm coils (below 1.0 ohm): These coils are used for direct-lung (DL) vaping, ideal for those seeking large vapour clouds and rich flavour. Try the Geekvape Z Series Coils 0.2ohm for powerful performance.
MTL coils (above 1.0 ohm): Used in mouth-to-lung vaping kits, these coils offer a tighter draw similar to traditional smoking. Great for high-nicotine e-liquids. Explore Voopoo PnP coils 1.0ohm.
Not all coils are compatible with all tanks or pods. Choosing the right coil depends on:
Your device’s power range, preferred vaping style (MTL or DL), type of e-liquid (VG/PG ratio), coil resistance and material.
For quick, flavourful hits, mesh coils like SMOK RPM Mesh Coils are a popular option. They heat evenly and offer excellent e-liquid absorption.
At FREESMO, we offer coils in various materials:

Vape coils don’t last forever, but with the right care, you can significantly extend their lifespan — saving money and improving your overall vaping experience. Typically, a coil lasts from 5 to 14 days, depending on usage, coil quality, e-liquid type, and maintenance practices. Here's how to make the most out of your coils:
Prime Your Coil Properly Before using a new coil, always prime it by saturating the cotton wick with e-liquid. Let it soak for at least 5–10 minutes before firing the device. This step prevents dry hits and extends coil life right from the start.
Use E-Liquid with the Right VG/PG Ratio Using high-VG liquids in MTL coils can clog or burn the coil quickly, while high-PG liquids in DL coils may lead to leaking or poor vapour production. Always match your e-liquid’s VG/PG ratio to the coil’s compatibility.
Avoid Chain Vaping Taking multiple rapid hits in a row doesn't give your wick enough time to absorb more e-liquid. This leads to dry hits and premature coil burning. Give your device a few seconds between puffs to allow re-saturation.
Maintain Optimal Wattage Every coil comes with a recommended wattage range. Exceeding it can scorch the wick and shorten coil life. Check the packaging or visit Freesmo.co.uk to view specs for your coil type.
While cleaning vape coils won’t make them last forever, it can offer temporary relief and help maintain performance — especially for rebuildable coils.
Note: This method works best for rebuildable coils or reusable pods. Disposable or heavily used coils are better off replaced.
Coil problems can impact flavour, vapour, and safety. Here's how to identify and solve the most common issues:
Burnt Taste
Gurgling or Leaking
Low Vapour Production
Spitback (E-liquid in Mouth)
With sustainability becoming a greater focus in vaping culture, it's important to dispose of used coils responsibly. Vape coils contain metal and cotton, making them non-biodegradable.
