If your vape starts tasting burnt, feels weak, or just isn’t delivering like it used to, chances are the coil needs changing. Vape coils don’t last forever, and knowing how long they should serve you—and how to spot when they’re done—is essential for keeping your device running smoothly and your flavours tasting right.
While the exact lifespan of a coil depends on how and what you vape, most last between 5 and 14 days. Some users stretch them out longer with careful use, while heavy vapers or those using sweetened e-liquids may find themselves replacing coils more frequently.
What Is a Vape Coil and What Does It Do?
The coil is the heart of your vape. It’s the part that heats up when you press the fire button, turning e-liquid into vapour. It’s made of a wire (or mesh) wrapped around a wick—usually cotton. Over time, residue builds up on the coil and clogs the wick, making it harder for the device to perform properly. Once that happens, it’s time for a change.
Coils are replaceable in most reusable vape kits. For disposable vapes, the coil is built-in and discarded with the rest of the device once performance drops off.
Factors That Affect Coil Lifespan
Several variables influence how long your coil will last:
Type of e-liquid: Sweet or dark-coloured e-liquids tend to gunk up coils faster. High-VG liquids are thicker and may also reduce coil life in some devices.
Wattage: Vaping at high wattages burns through both e-liquid and coils more quickly. The hotter the coil runs, the faster it breaks down.
Vaping frequency: The more you use your vape, the harder the coil works. All-day vaping will wear out a coil faster than light, occasional use.
Device and coil type: Mesh coils often last longer than traditional wire coils due to their even heating and wider surface area. Pods with built-in coils may be less durable depending on quality.
Priming and care: A new coil should be properly primed before use—meaning the wick is soaked in e-liquid and left to sit for a few minutes. Failing to do this can cause it to burn out almost immediately.
Signs Your Coil Needs Replacing
Even if you’re not tracking days, your vape will tell you when the coil is nearing the end of its life. Common signs include:
- A burnt or scorched taste
- Weak or muted flavour
- Gurgling or leaking
- Reduced vapour production
- Difficulty drawing or inconsistent performance
If you’re experiencing any of these, it’s time to switch out your coil. Delaying replacement can lead to a worse taste, lower performance, and even damage to your device in extreme cases.
How to Make Coils Last Longer
While you can’t avoid replacing coils altogether, a few habits can help stretch their lifespan:
- Always prime new coils before use
- Stick to moderate wattage settings
- Avoid chain vaping—give your coil time to re-saturate between puffs
- Choose clearer, less sugary e-liquids when possible
- Clean your tank regularly to avoid buildup
Every coil has a limit, but a little care goes a long way in getting the most out of each one.
Final Word
Most vape coils last about a week or two, depending on your habits and the type of device you use. Knowing the signs of a worn-out coil—and replacing it before it ruins your experience—keeps your vape running at its best. With a bit of attention to how you vape and what you’re using, you can make your coils last longer and enjoy smoother, cleaner hits every time.
