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 factor, 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. On the other hand, if you vape occasionally, the coil could last much longer than two weeks.  
  • Vaping style – Long and frequent puffs wear out the coil faster. To extend its lifespan, try taking longer breaks between puffs. This allows the wick to absorb enough e-liquid, preventing it from burning and damaging the coil. 
  • Type of e-liquid – Choose your e-liquid based on your vape device, power settings, and vaping style. VG e-liquids are thicker, produce more vapour and are suitable for high-power devices. PG e-liquids are thinner, deliver intense flavour, and work well with lower-power devices. You can also opt for a 50/50 blend, which combines PG and VG in equal proportions.  
  • E-liquid flavour – It’s not just about the type of e-liquid but also the flavour itself. Sweet e-liquids contain a high amount of sweeteners, which accumulate on the coil, caramelize, and eventually burn. This results in a burnt taste and, over time, damages both the wick and the coil.  
  • Coil quality and material – The lifespan of a coil is also affected by the material it’s made from. Don’t cut corners when purchasing coils. Choose accessories from reputable brands that guarantee high quality. 

Is It Possible to Extend the Lifespan of a Coil?

Now that you know how long a coil should last, the question remains—can its lifespan be extended? The answer is yes, and there are several ways to do so:  

  • Clean the coil regularly – Regardless of the e-liquid you use, make sure to clean your vape at regular intervals. This prevents buildup and helps extend its lifespan. Not sure how to clean a coil? The process is simple: first, unscrew and remove it from the vape. Then, soak it in vinegar or ethanol for a few hours, rinse it under cold water, dry it thoroughly, and place it back in the device.  
  • Take breaks between puffs – Pausing between puffs allows the coil to cool down, preventing excessive wear.
  • Refill the e-liquid regularly – Check and top up the e-liquid tank to ensure the vape isn’t running dry, which could cause the coil to overheat.  
  • Prime the coil before first use – When replacing a coil, apply a few drops of e-liquid onto it and wait a moment before using it. This allows the nearby wick to absorb the liquid and prevents it from burning when you take your first puffs.  
  • Choose less sweet e-liquids – If you want to avoid frequent coil cleaning and replacement, opt for e-liquids with lower sweetener content. Menthol flavours, for example, are a good choice.  
  • Set the correct wattage – Some vape devices allow you to adjust the power output. When setting it, consider the coil’s recommended wattage range, as exceeding it may damage the coil.  

How to Know When to Replace a Coil?

Several signs indicate that it’s time to replace your coil:  

Weakened Flavour

If you notice that your e-liquid no longer has the strong flavour you are used to, and you haven’t changed brands or products, the coil is likely the issue. It could be old and worn out or clogged due to improper cleaning or excessive sweetener buildup. 

First, inspect the coil. If you bought the coil only a few days ago, try cleaning it first—it may just be clogged, which affects the flavour.  

However, if the coil is too old, the cleaning won’t help and it’s time for a replacement.

Burnt Taste

You will experience a burnt taste when the coil is so dirty that it needs to be replaced. In most cases, even deep cleaning with alcohol or vinegar won’t help. 

Reduced Vapour Production

Noticing that your vape is producing less vapour than usual? Think about when you last changed the coil. As coils age, they lose efficiency, which diminishes the overall vaping experience.  

Unusual Noises

An old coil may not function properly, preventing the e-liquid from evaporating correctly. This can cause some liquid to leak into other parts of the vape, leading to unnatural sounds like gurgling. 

Never ignore unusual noises. If left unchecked, your device’s condition could worsen to the point where hot liquid leaks or is accidentally inhaled.  

Discoloured E-Liquid

Most e-liquids have a clear appearance with a slight yellow tint. However, a worn-out coil can burn and turn the liquid brown. This not only negatively affects the taste but can also be harmful to your health.  

If you notice an unnatural discoloration in your e-liquid, stop vaping immediately and inspect the coil.

How to Replace a Coil?

Have you determined that your coil is no longer working properly? Replace it as soon as possible. Firstly, buy a new coil. There are many different types of coils available on the market today. When selecting one, consider three key factors:  

  • resistance (measured in ohms Ω),
  • compatibility with your device,
  • vaping style (MTL, DTL, or RDTL vaping).

In general, for MTL vaping you will need a coil with higher resistance – ideally between 0.7 to 1.3 Ω. On the other hand, for DTL vaping, a coil with a resistance of 0.15 to 0.6 Ω will suffice. 

Once you have the coil, proceed with the replacement. The process varies depending on your device, but in most cases, you simply open it, unscrew the old coil, and replace it with a new one.  

Now you can fill your vape with your favourite e-liquid and start using it. However, wait at least 10 to 15 minutes before vaping. During this time, the wick will absorb the liquid properly, preventing the coil from burning and avoiding an unpleasant burnt taste.
