Why do vape coils burn out fast? If you’ve ever asked yourself this question, you’re not alone. Some e-juices tend to gunk up coils more quickly, leading to burnt hits and more frequent replacements. Understanding why this happens and how to prevent it can help extend coil life, saving you time and money.
Why Do Vape Coils Burn Out Fast?
1. High Sweetener Content
Many e-liquids, especially dessert and candy flavours, contain high levels of sweeteners like sucralose. While these enhance the taste, they also caramelize on the coil when heated, leading to residue buildup. Over time, this buildup creates a thick gunk that burns, reducing coil lifespan.
2. Thick VG-Based E-Juices
Vegetable Glycerin (VG) is a thicker liquid compared to Propylene Glycol (PG). While high-VG e-liquids produce smoother, denser clouds, they also take longer to wick into the coil. If your device isn’t designed for high-VG juice, dry hits can occur, which is one reason why vape coils burn out fast.
3. Dark & Artificially-Coloured E-Liquids
Darker e-liquids and those containing artificial colouring often leave more residue on coils. Over time, these compounds accumulate, leading to faster coil degradation and a burnt taste.
4. High Wattage Vaping
Vaping at a wattage higher than recommended for your coil can burn the wick and caramelize e-liquid faster, leading to a shorter coil life. High wattage can also cause e-liquid to vaporize too quickly, leaving unvaporized residue behind.
5. Improper Priming of Coils
When you install a new coil, failing to properly prime it with e-liquid can result in a dry hit, burning the cotton wick almost immediately. Once burnt, the wick cannot absorb e-liquid properly, leading to a consistently burnt taste.
How to Prevent Coils from Burning Out Too Quickly
1. Choose Low-Sweetener E-Juices
Opt for e-liquids with little to no added sweeteners. While sweetened flavours are tempting, they can drastically reduce coil lifespan. Knowing why do vape coils burn out fast can help you choose cleaner, less coil-damaging options.
2. Use the Right VG/PG Ratio for Your Device
- Sub-ohm tanks: Work best with 70VG/30PG or 80VG/20PG ratios.
- Pod systems & MTL (Mouth-To-Lung) tanks: Perform better with 50VG/50PG or 60VG/40PG blends. Using the wrong ratio can lead to wicking issues, dry hits, and faster coil burnout.
3. Avoid Dark & Heavily Coloured E-Liquids
Clearer e-liquids tend to leave less residue, keeping your coils cleaner for longer. Choosing high-quality flavour concentrates without excessive colourants can make a difference. However, if you are making your own e-juice, keep in mind that some flavours are naturally darker due to their composition, and this would be an exception.
4. Adjust Your Wattage to Coil Recommendations
Always check the recommended wattage range printed on your coil. Staying within this range prevents excessive heat from damaging the wick and e-liquid.
5. Properly Prime Your Coils
Before using a new coil:
- Apply a few drops of e-liquid directly onto the cotton inside the coil.
- Install the coil and fill the tank.
- Let it sit for 5-10 minutes to fully saturate.
- Take a few primer puffs without firing the device to draw liquid into the wick.
6. Keep Your Coils Clean Between E-Liquid Changes
For pre-built coils, frequently switching e-liquids without proper cleaning can lead to faster residue buildup. Over time, this buildup can create a layer of gunk that affects flavour quality and reduces coil lifespan. To minimize this, consider rinsing your tank and coil housing with warm water or using a small amount of unflavoured e-liquid to flush out remnants of previous flavours.
7. Use Temperature Control Mode (If Available)
Some devices have temperature control (TC) mode, which prevents overheating and burning of the wick. If your mod supports TC mode and you’re using compatible coils, this can be an excellent way to prolong coil life.
Final Thoughts
If you’ve been wondering why do vape coils burn out fast, the answer usually comes down to sweeteners, wattage, coil priming, and choosing the right VG/PG ratio. By understanding these factors and maintaining your coils properly, you can extend coil lifespan and enjoy a cleaner, better-tasting vape experience.
