Vape systems, also known as vaporizers, are electronic devices that heat and vaporize a liquid solution known as e-liquid or vape juice. The resulting vapor is then inhaled by the user, providing a sensation similar to smoking but without the combustion of tobacco. Here's an overview of how vape systems work and their main components:

1. Battery: The battery is the power source of the vape, providing energy to heat the coil or atomizer. Most vape batteries are rechargeable lithium-ion types and can be either built-in or removable, depending on the device .

2. Atomizer or Coil: The atomizer, often referred to as a coil, is a heating element made from a resistive wire. When activated, it heats up and vaporizes the e-liquid. The coil is surrounded by a wicking material, usually cotton, which absorbs the e-liquid and ensures it reaches the coil for vaporization .

3. E-Liquid (or E-Juice): This is the liquid solution that is vaporized. It often contains nicotine, flavorings, and bases such as propylene glycol (PG) or vegetable glycerin (VG) .

4. Tank or Cartridge: This container holds the e-liquid. Tanks are typically refillable, while cartridges are mostly disposable .

5. Mouthpiece (or Drip Tip): This is the part of the vape device that the user inhales from .

6. Airflow System: Consists of the intake vent at the bottom of the tank or pod and the chimney leading from the coil assembly to the mouthpiece .

7. Logic Board, Integrated Circuit, and Firmware: These components control the functions of the vaping device, including power delivery and safety features like automatic timers, temperature monitors, and battery monitors .

8. Threading or Pod Contacts: This part connects the vape's tank or pod to the battery, ensuring electrical conductivity .

9. Reservoir and Chimney: The reservoir holds the e-liquid, and the chimney is part of the airflow system .

10. Coil Assembly: Comprises the wick and heating element. The wick absorbs e-liquid, and the heating element vaporizes it .

When you activate a vape device, the battery powers the heating element, which vaporizes the e-liquid in the coil. Inhaling draws air through the device, over the coil, and carries vapor to your mouth .

Vape systems can be categorized into several types, including cigalikes, vape pens, pod systems, box mods, and mechanical mods, each with its own set of pros and cons . Understanding the components and how they work together is essential for users to properly maintain and operate their devices and to make informed decisions when choosing a vape system .
