Understand How a Vape Pen Works

A vape pen is basically made using four parts such as a battery, an atomizer, a cartridge, and some e-liquid. The battery is the device’s power source; it provides the energy required to start the vaping process. When you turn on the battery, it transmits energy to the atomizer, which is a heating element that vaporizes the e-liquid. 

The atomizer warms up to a certain temperature, causing the e-liquid to evaporate. After that, you can inhale the vapor with the help of a mouthpiece. Vape pen provides you with the chosen flavor and nicotine level.

The tank or cartridge is the container for the e-liquid. This cartridge has a conducting substance that collects the liquid and feeds it to the atomizer. This regulated e-liquid distribution is an important part of the vaping process, and it provides a consistent experience to you.

Understanding the overall process of how a vape pen works can be helpful for you. You can learn the reasons for vape pen oil leaking and how to address them with this important knowledge correctly.

Reasons Behind Why Your Vape Pen Is Leaking Oil

Vape pen oil leaking problem can be very frustrating. Here are some reasons why your vape pen might leak oil.

Why Is My Vape Pen Leaking Oil and How to Fix it?
  • Bad Storage

Improper storage is a major cause of vape pen oil leaking. Extreme temperatures, such as a hot automobile or cold weather, might cause the e-liquid to expand or contract, and this can cause oil leaks.

  • Overfilling of the Tank

A typical error that leads to oil leaks is overfilling your tank or cartridge. When you overfill, there is no place for the extra e-liquid, which escapes through the airflow holes or the mouthpiece.

  • Improper Coil Installation

When you replace the coil and you have leakage, you can make sure you put it correctly. An improperly seated coil might provide holes through which oil can flow.

  • Airflow Is Not Proper

Vape pens totally depend on correct airflow. If the airflow is excessively limited or too wide, the balance will be disturbed and might cause oil leaks. This problem can happen if you alter the airflow ring by accident or if it loosens over time.

  • Thin E-Liquid

Different concentrations of e-liquids are thinner liquids that have more risk of oil leaks. If you choose a thin e-liquid, it can easily pass past the coil and into the airflow system.

  • Manufacturer Flaws

Although it is less prevalent, it is important to consider the possibility of manufacturing flaws. If your vape pen began leaking soon after purchase, a flaw in the device itself might be the source of the problem.
