• The type of tank that you have
• The quality of the particular coils
• The voltage/wattage that you are vaping at
• The rate at which you are vaping through your e-liquid
• The type of juice you are vaping

On average, a decently constructed coil for a sub-ohm tank should last you 4 days to 1 week.

If you vape less because you cannot vape during work hours, or you do not vape throughout the day, then your coils are likely to last twice as long.

What volt do you vape at?
The voltage or wattage affects the longevity of your coil too because of the heat that is induced. The hotter the coil gets, the more juice that is boiled through the cotton and upon the coil, which means the rate of juice being vaporized is accelerated; this reduces the life of your coil because there is always a limit on amount of juice that can be vaporized through your coil before it’s finished.

What does the vape cotton look like?
Eventually the cotton will reflect this deterioration with poor flavor, and eventually the coloration of the cotton within the coil as well. You cannot always see the deterioration of the coil and cotton from the outside of the tank though. When you begin tasting a lack of flavor or sometimes a weird burnt flavor, you know your coil is just about done. If you open your tank and look at the inside of the coil and on the inside of the coil, the cotton looks dark brown, then your coil surely needs to be replaced.

What vape juice are you using?
The type of flavors you vape can be a factor as well. E-liquids with added sweeteners in them cause additional corrosion of the coil, and this will cause your coil to burn out much faster as the corrosion seeps into the cotton. E-liquids without added sweeteners differ as well. Typically, savory and dessert flavors will also reduce the life of your coil in comparison to fruit and candy vape flavors.

Knowing what is in your vape juice can help you determine a cause for why your coils are burning out faster. Compare this with other e-liquids you use to see which one is the culprit of killing your coils.

How can your vape tank burn coils faster?
The type of tank you have can also make a difference because some types of coils and tanks are more efficient than others. For example, Smok branded tanks are notorious for not only leaking, but coils burning out quickly due to a lack of quality control in their manufacturing process. Geekvape is a well-known brand for quality and their coils typically last twice as long as Smok coils. There are also disposable tanks as well. The Freemax Gemm disposables will last a few days at most, but the Sikary Nunu tank lasts as long as your average coil, usually about a week.

One last thing...

When gauging your coil, it’s important to consider all these factors. If you’re building your coils and you have an RDA, the quality of the coil is dependent on your abilities to build. If you are properly changing your cotton, cleaning your coils, and you have a well-built coil, typically you can extend the life of your coil to a couple months or more and maintain the flavor of your vapor.
