Many different connection types are used to connect the atty/carto to the device or battery.  The most common are 510, 901, 808, 801.  In my humble opinion, the 510 connection is the most popular type.

A device that you first charge and then use to charge your electronic cigarette batteries while out on the go and away from an outlet.  These are generally used and helpful for smaller electronic cigarette models with less vape time between charges on the batteries.

What electronic cigarette users (vapers) call a traditional (or real) tobacco cigarette.

Advanced Personal Vaporizer. This loosely describes anything other than a mini or eGo battery. It includes both Variable Volt/Watt and Mechanical devices.

The atomizer is a the heating unit of the electronic cigarette.  Usually metal wire wrapped around a core.  It get hot when electricity from the power source is applied and “vaporized” the e-liquid.  The generates the vapor.

Automatic batteries or devices will activate the heating element automatically when a puff is taken.  You do not have to use a button to activate the heating element.

The battery is the power source for an electronic cigarette.  It provides power to the heating element which vaporized the e-liquid.  Some batteries are integrated into the device like an EGO.  These devices will come with a charger that is made for the device.  Most mods have removable batteries and require an external charger.

A U or V shaped covering over the heating coil of some atomizers.  It is usually metal covered by an absorbent material designed to wick e-liquid from a cartridge filler to the heating element.

The cartomizer combines a heating element and juice delivery system into a single unit.

A cartridge holds the e-liquid, sits on top of the atomizer, and directs the liquid into it.  The cartridge should be considered “old technology” at this point.
