Main body: This is the main outer casing that attaches to the base of the vape tank and provides electrical contact to the coil.
Coil: This is the wrapped wire that heats up when you draw and activate your vape. The power from the battery heats up the coil which turns the e-liquid to vapor.
Wicking material
This is absorbent material within the atomizer, usually silica rope or cotton. It basically transfers your vape juice from the tank it’s stored into onto the coil for vaporization.
