Why is the vapor output of e-cigarettes getting lower?

Vapor production is one of the standards used to evaluate the quality of e-cigarettes. Many users report that when they first start using an e-cigarette, the vapor output is very large, but after using it for a long time, the amount of vapor decreases. Why does this happen? Today, let’s analyze the main reasons.

If the vapor output is very low in the first few days, it is most likely a quality issue. If the resistance of the atomizer coil is too high, the wick does not absorb e-liquid smoothly, the battery quality of the power device is poor, or too much e-liquid has seeped into the atomizer or is even leaking, the vapor production will be very low. Disposable cigarette-style devices will also generally produce less vapor. In this situation, the only solution is to buy a new atomizer.

If the atomizer has been used for a long time and the vapor output is getting lower and lower, you can check whether the atomizer is clogged, whether carbon buildup has formed, whether the wick is burnt, and so on. If so, there is a very simple solution: cleaning.

The battery voltage and the atomizer resistance may not match. For example, if the resistance of the e-cigarette atomizer is too low, the battery may not be able to drive it properly, so little or no vapor will be produced. In this case, you need to replace the battery or atomizer so that the parameters match.

It is also possible that you are using e-liquid with a low VG content. VG (commonly known as vegetable glycerin) is one of the basic ingredients in e-liquid. Its main function is to produce vapor. Therefore, if you switch to e-liquid with a lower VG content, you will produce less vapor. When buying e-liquid, carefully check the product description or ask the seller about the VG content. If you want more vapor, choose a higher-VG e-liquid; if you want less vapor, choose one with a lower VG content.

If you want a large amount of vapor, you need to choose a suitable atomizer. In simple terms, the lower the atomizer resistance and the higher the voltage, the greater the vapor production.

However, this will speed up the vaporization of the e-liquid. Once the wicking material in the e-cigarette can no longer absorb e-liquid as fast as it is being vaporized, the wicking material will burn out quickly.
