Battery – The battery provides power to the coils of the atomizer, which is what allows it to heat up and vaporize e-liquid, wax or dry herb. This is the power supply for your vape pen.
Coil – This is a piece of wire that has been wrapped around a small cylinder to create a coil that vaporizes e-liquid or wax. They usually contain some kind of wicking material.
Wick – This is the material found in a coil that absorbs e-liquid and wax thus optimizing vaporization. For e-liquid, this material is usually silica or cotton and for wax, quartz and ceramic it is quite common.
Atomizer – The atomizer is the part of a vape pen that contains some kind of coil that will heat up when the power button is engaged.
Power button – The power button, also called the fire button, is used to engage the atomizer. It is typically also used to turn the battery on and off by pressing it five times. Some batteries also allow the user to adjust their voltage by pressing the Power button three times.
Mouthpiece – This is the part of the vape pen that you put your mouth on and inhale from. You might hear someone refer to this as the drip tip, even if you are not dripping your liquid into it.
Fill port – Some vape pens might have what we call a fill port. This allows you to easily fill up while on the battery, instead of having to take it off and unscrew the whole thing apart.
Charging port – Some vape pens may contain a micro-USB charging port on the bottom or side. This usually allows for pass-through charging, meaning you can vape while it is charging.
Airflow control – Some vape pens may have airflow control, also referred to as an AFC ring. It allows you to customize the draw resistance to either Mouth-to-Lung or Direct-Lung vaping.
Threading – These are the threads on the top of the battery in which you screw on your atomizer. Most vape pens have some kind of threading, usually 510, eGo, or both. There are some rare alternatives that we will discuss later.
