What Factors Affect the Lifespan of an E-Cigarette Coil?

In addition to e-liquid, another key part of an e-cigarette is the atomizer coil. Many friends who are not familiar with e-cigarettes may not know what an atomizer coil is or how long it lasts. Below, let’s take a detailed look at the lifespan of an e-cigarette atomizer coil with the help of the editor from an e-cigarette franchise company.

1. Power. Atomizer coils usually have a tolerance marked on the outer shell. For example, for 1.6Ω, 8-15W, this label means the finished atomizer coil has a resistance of 1.6Ω, and the officially recommended power is 8W-15W. Users can find the flavor they prefer within this power range.

If the user sets the output power too high, the high temperature generated by the coil will cause the e-liquid to evaporate excessively. If the e-liquid is not replenished in time, the surrounding cotton will burn, causing a burnt taste and affecting flavor and overall performance.

2. E-liquid. One of the biggest impacts of e-liquid on atomizer lifespan is carbon buildup. E-liquid moves through the cotton to the coil, and when the coil is heated, vapor is produced. Due to the high temperature, a black substance will form on the coil, commonly known as “carbon buildup.” The basic ingredients of e-liquid are similar, but the rate of carbon buildup differs because the raw materials and additives used by each brand are different.

Carbon buildup affects the heating efficiency of the coil and the taste of the vapor, thereby reducing the flavor and performance of the atomizer. Due to limitations of the heating method, this carbon buildup phenomenon cannot be completely avoided, and it has a significant impact on the lifespan of the atomizer coil.

3. Improper use. When using a new atomizer coil, whether a finished coil or a DIY RBA setup, you need to learn the correct way to use it. More attention should be paid to the preparation before use, especially for finished coils. After receiving it, the user should first remove the coil, then drip a small amount of e-liquid into the cotton around the liquid inlet holes, and then reassemble it so the cotton becomes fully saturated. This step is called “priming the coil.”

4. High-VG e-liquid. When a tank-style atomizer uses high-VG e-liquid, if the e-liquid has poor fluidity, the wicking performance will be reduced and the atomizer coil may easily burn. Generally speaking, the higher the VG, the larger the vapor volume, the softer the inhale, and the thicker the e-liquid, meaning it flows less easily. However, the wicking systems of some finished tank atomizers cannot handle high-VG e-liquid well, so the wicking speed cannot keep up and the atomizer coil burns out. Therefore, the PG/VG ratio of the e-liquid is also a factor affecting atomizer coil lifespan.
