How to prolong the coil life of your sub-ohm tanks?

This is the big question when someone starts vaping: how often do I have to replace my sub-ohm tank coils? The short answer is: it depends… Depends on how often you vape, the type of coil you are using, the wicking material inside, and the e-liquid you are using.

Essentially, you have to replace your coil when you experience a flavor loss or burnt taste. In this article, we are going to give you a few tips on how to prolong the coil life of your sub-ohm tanks, and even a tip to clean and revive your pre-made coils.

1. Avoid vaping at very high wattage for a long time

Do you enjoy taking very long puffs at high wattage? Well, this is exactly what you have to avoid if you want your sub-ohm coils to last longer. Especially if the draining of your sub-ohm tank coil is not the best. Most coils will let you know which recommended wattage you have to use (ie: 50-80W). We advise you to refrain from pushing it to its limits. In addition, you should not take very long puffs. By doing this, you considerably reduce the chance of burning the cotton too fast.

2. Stay away from sweet liquids when using your sub-ohm tanks

We all love sweet stuff, don’t we? Unfortunately, sweet e-liquid flavors are big enemies for sub-ohm tank coils! Most sweet liquids are dark and contain a lot of sweetener. When this sweetener evaporates, it produces coil gunk. This is a dark crust that piles up on your wire and cotton.

Eventually, the crust becomes so thick that you can taste it when you vape — most likely because the coil is actually burning some of the gunk off. After a while, coil gunk makes the experience of vaping so unpleasant that you have no choice but replacing or cleaning the coil. Cleaning coils is way easier when you are using a rebuildable tank because you can re-wick it and clean the wire. However, there are some tricks to clean and revive sub-ohm pre-made coils too…

3. Clean and revive the life of your sub-ohm coil

If you see your coil is starting to build up some gunk or it just simply looks too dirty and the flavor is not the same any more, then there is a trick to bring your coil back to life. You must leave it covered in vodka or pure grain alcohol all night long (do not use any other type of alcohol). After 12 hours, the vodka will take a lot of dirt out of the cotton and wire.

Just leave the coil drying for another few hours in a sunny place so the alcohol completely evaporates. It is advised to use vodka or grain alcohol because it does not contain sugar. Once the coil is completely dry, you can reuse it again. The coil won’t be brand new but you will see it much cleaner and the flavor will improve again.

4. Don’t wait until the end to refill your sub-ohm tank

Last but not least, there is also a very basic rule you must stick to if you want your coils to last longer: never wait until the tank is almost empty to refill it. The draining holes of most coils rarely reach the bottom of the tank. Therefore, it is strongly advised to refill it before you are running out of e-liquid. The cotton must be always well saturated with liquid. You will avoid burning the cotton.

Conclusion 

With these 4 tips, you will be able to prolong the coil life of your sub-ohm tanks. Have you ever tried any of these tips? Is there any other tip you normally use? We’d like to know it! Please let us know in the comments down below!

Vaping is not only a profession for me but also a passion. I quit smoking thanks to vaping almost 3 years ago. I helped many smokers to switch to vaping since as I am convinced vaping is a much healhier alternative to tobbaco smoking.
