Quick answer: most vape coils last about one to three weeks. Heavy vaping, high wattage and very sweet e-liquids wear them out faster; mouth-to-lung and salt nic coils used at low wattage often last longer. Change the coil when the flavor fades, the vape tastes burnt, or vapor drops off.
Every coil wears out eventually. How fast depends on the coil, your device’s power, the e-liquid you use and how much you vape. Here is what to expect, how to tell when it is time for a new one, and how to get more life out of each coil.
How long do vape coils last?
For most people a coil lasts one to three weeks. Some heavy vapers change coils every few days, while light vapers using low-wattage pods can go three weeks or more. As a rough guide:
| Coil type | Typical life |
|---|---|
| High-wattage sub-ohm coils | About 5 to 10 days |
| Mesh coils | About 1 to 2 weeks |
| Low-wattage MTL and salt nic coils or pods | About 1 to 3 weeks |
| Rebuildable coils | As long as you keep re-wicking them; the wire lasts much longer than the cotton |
Signs it is time to change your coil
- Burnt or harsh taste. The most common sign: the wick is dry, worn or clogged with residue.
- Weak or muted flavor. Buildup on the coil keeps it from vaporizing the e-liquid properly.
- Less vapor. A worn coil heats less evenly and produces noticeably smaller clouds.
- Gurgling or leaking that continues even after you check the tank is put together correctly.
- Dark, gunky residue on the cotton or wire when you look at the coil.
How to make your coils last longer
- Prime every new coil. Drip a few drops of e-liquid onto the exposed cotton, fill the tank, and let it sit for 5 to 10 minutes before your first puff. Start at the low end of the coil’s wattage range.
- Stay within the wattage range printed on the coil. Running it hotter burns the cotton and shortens its life.
- Don’t chain vape. Give the wick a few seconds to soak back up between puffs.
- Go easy on sweet e-liquid. Sweeteners and very sweet desserts leave residue on the coil faster. If you add sweetener, use as little as tastes right.
- Keep the tank topped up so the wicking holes stay covered with e-liquid.
- Match the e-liquid to the coil. Higher-VG e-liquid is thicker and suits sub-ohm coils; thin, high-PG e-liquid can flood them. Low-wattage pods suit 50/50 or higher PG and salt nic. See PG vs VG.
How long do SMOK coils last?
SMOK coils follow the same pattern. High-wattage tank coils like the TFV18, TFV16 and TFV12 often last about one to two weeks; lower-power coils and pods such as the LP1 for the Novo 4 and the RPM 3 for the Nord 6 can last longer when vaped at moderate wattage. Mesh coils usually keep their flavor longer than older wire coils.
Find the right replacement coil
Coils are made for specific tanks and kits. Our vape coils page has a “find the right coil” table matching SMOK, Aspire, Kanger, GeekVape, Uwell, Vaporesso and Joyetech coils to their tanks. Every coil is 10% off when you buy 5 or more of the same coil, up to the limit on each product page, so it is worth keeping a few spares.
Vape coil FAQ
How often should I change my vape coil?
About every one to three weeks for most people, or whenever the flavor fades, it tastes burnt, or vapor drops off.
Why does my new coil taste burnt?
Usually because it was not primed. The cotton needs to be fully soaked before you fire it, so drip a little e-liquid into the coil, let the filled tank sit for 5 to 10 minutes, and start at low wattage. More in our burnt coil guide.
Can I clean a vape coil to reuse it?
Rinsing a coil in warm water and letting it dry completely can sometimes freshen it briefly, but it rarely brings back full flavor. Replacing it is the reliable fix.
Do salt nic coils last longer?
Often, yes. Salt nic pods and coils run at low wattage, so the cotton burns more slowly, although very sweet e-liquids can still wear them out quickly.
