How Long Does a Coil Last and How to Properly Maintain It?
One of the most crucial parts of a vape is the coil. This component primarily serves to convert e-liquid into vapour, but it has a limited lifespan. Its longevity depends on several factors, including the flavour of the e-liquid and how often you vape. Are you wondering how long a coil lasts and what signs indicate that it needs to be replaced? We have prepared all the key information for you.
What Are Vape Coils and How Do They Work?
The coil is an essential part of every vape. Its function is to turn e-liquid into vapour. It is a small wire made from materials such as nichrome, stainless steel, or nickel, which heats up when electricity from the battery passes through it. This increases the temperature of the e-liquid, causing it to gradually evaporate.
Additionally, the coil can influence the flavour and intensity of the e-liquid, as well as the amount of vapour produced.
How Long Does a Coil Last?
Just like other vape components, coils have a limited lifespan. They typically last between 1 to 2 weeks, but the exact duration depends on several factors:
- Frequency of vaping – If you vape frequently and in large quantities, you may need to replace the coil within just a few days. If you vape occasionally, the coil could last longer than two weeks.
- Vaping style – Long and frequent puffs wear out the coil faster. To extend its lifespan, take breaks between puffs so the wick can absorb enough e-liquid and avoid burning.
- Type of e-liquid – Choose e-liquid based on your device, power settings, and vaping style. VG liquids are thicker and suitable for high-power devices. PG liquids are thinner and work well with lower-power devices. A 50/50 blend combines both.
- E-liquid flavour – Sweet liquids often contain sweeteners that build up on the coil, caramelise, and burn, which damages the coil and wick.
- Coil quality and material – Lifespan depends on material quality. Always choose coils from reputable brands.
Is It Possible to Extend the Lifespan of a Coil?
Yes, there are several ways to extend coil lifespan:
- Clean the coil regularly – Remove the coil, soak it in vinegar or ethanol for a few hours, rinse with cold water, dry completely, then reinstall.
- Take breaks between puffs – Allows the coil to cool down and reduces wear.
- Refill e-liquid regularly – Prevents dry burning and overheating.
- Prime the coil before first use – Add a few drops of e-liquid to the coil and wait before vaping.
- Choose less sweet e-liquids – Helps reduce buildup. Menthol flavours are often a good choice.
- Set correct wattage – Always stay within the coil’s recommended wattage range.
How to Know When to Replace a Coil?
Several signs indicate that it’s time to replace your coil:
Weakened Flavour
If flavour becomes weaker and you haven’t changed liquid, the coil may be worn or clogged due to sweetener buildup or poor cleaning.
First, inspect and clean the coil if it is still relatively new. If it is old, replacement is recommended.
Burnt Taste
A burnt taste usually means the coil is too dirty or damaged and must be replaced. Cleaning often will not fix it.
Reduced Vapour Production
Older coils lose efficiency, resulting in less vapour and weaker performance.
Unusual Noises
Gurgling or strange sounds may indicate liquid leakage caused by a failing coil. Do not ignore this, as it may lead to liquid leaking or being inhaled.
Discoloured E-Liquid
Most e-liquids are clear with a slight yellow tint. If liquid turns brown, the coil may be burning and contaminating the liquid.
If discoloration appears, stop vaping immediately and check the coil.
How to Replace a Coil?
If your coil is no longer working properly, replace it as soon as possible. When buying a new coil, consider:
- Resistance (measured in ohms Ω),
- Device compatibility,
- Vaping style (MTL, DTL, or RDTL).
For MTL vaping, use coils with 0.7 – 1.3 Ω. For DTL vaping, use coils with 0.15 – 0.6 Ω.
Replacement is usually simple: open the device, remove the old coil, and install the new one.
After replacing, wait 10 to 15 minutes before vaping so the wick can fully absorb e-liquid.
No Coil Alternatives
If you prefer minimal maintenance, consider devices with built-in coils. Disposable vapes are the simplest option—use them until flavour or vapour drops, then replace the device.
Another option is a closed pod system, where you keep the battery and only replace prefilled pods when performance decreases.
Make Every Coil Count
Most coils last about one to two weeks depending on usage, liquid type, and power settings. You can extend lifespan by priming new coils, taking breaks between puffs, keeping the tank filled, choosing less sweet liquids, and staying within recommended wattage ranges.
If you prefer a maintenance-free experience, consider disposable or closed pod systems where you simply replace the pod or device when performance drops.
