Introduction to the service life of electronic cigarette cartridges and influencing factors

As we all know, the atomizer coil is a key component of the e-cigarette. A good coil can enhance the e-cigarette experience, while a faulty coil will ruin the e-cigarette experience. There are two main types of atomizer cores currently on the market: ceramic coils and cotton coils. No matter what type of coil, it needs to be replaced once its service life is exceeded. So, what is the lifespan of an atomizer coil?

Classification of atomizer coils

The classification of atomizer coils corresponds to the classification of atomizers. Atomizers can be divided into two main categories: "pre-packed atomizers" and "RBA (rebuildable atomizer) atomizers". Coil life varies depending on the type of carburetor.

Pre-installed atomizers, as the name suggests, use pre-made coils that can be replaced directly by the user. For example, Dasvape’s D60 and D80 use pre-made atomizer coils.

Atomizer coil life

Generally speaking, the service life of a pre-installed atomizer core should be about 7 days to two weeks. However, lifespan may vary based on individual frequency of use and e-liquid.

When it comes to RBA coils, their lifespan can vary greatly based on personal preference. Some people like to change their coils every day or even every tank of e-juice, while others change them every 3-5 days, and some might even change them every two weeks or every month. It can be shocking to see the condition of your coils when you replace them.

Factors affecting atomizer coil life

The service life of an atomizer coil depends on the smoking habits of the user. So, what are the factors that affect the life of the atomizer coil?

A. Power: Atomizer coils have a specific power range they can handle. If the user sets the output power too high, the coil will generate too much heat, causing the surrounding cotton to be burned before it has time to replenish the e-liquid. This can cause a burnt taste and affect the flavor and smoking experience.

B. E-liquid: E-liquid has a significant impact on the service life of the atomizer coil, especially in terms of "carbon deposits". Different brands of e-cigarette oil have different ingredients and additives, resulting in different carbon deposition rates. For example, "Malaysian e-liquid" is known for its high carbon deposition rate. If using this type of e-liquid, it is recommended to use an RBA atomizer. Even if carbon buildup occurs quickly and affects flavor and performance, new coils can be easily rebuilt.

C. Misuse: Most pre-made atomizers come with a coil installed. It is recommended to remove the coil first, drip a small amount of e-liquid onto the cotton around the coil and into the core hole. Some people call this step "priming the coil." The purpose is to soak the cotton in advance so that it can absorb the e-liquid more smoothly. If the coil is not fully saturated, it may burn the cotton, producing an unpleasant burnt smell.

D. High VG e-liquid: Generally speaking, the higher the VG (vegetable glycerin) content, the more viscous the e-liquid will be, the less fluid it will be, and the greater the smoke it will produce. High VG e-liquids are often used with devices designed to produce large amounts of vapor, such as drip atomizers. However, some prefabricated atomizers with smaller wick channels may have difficulty keeping up with the flow of high VG e-liquid, resulting in coil burnout. Therefore, the PG/VG ratio of e-liquid will also affect the life of the atomizer core.
