Battery– this may be a disposable battery, or rechargeable. Many of the batteries are built into the housing of the electronic cigarette and are not accessible. The bigger the battery, the longer you can go between charges. Most batteries put out around 3.7 volts unless they are variable voltage.
Disposable– throw-away one-time use. Just use and toss in trash when done. These are no hassle and easy to use.
Rechargeable– recharge the battery and replace the cartridge why empty
Vape Pen– bigger rechargeable battery and more powerful than disposable or rechargeable.
Vape – biggest electronic cigarette and usually heavier and bulky. Most have LED screen and adjustable settings such as voltage output. Many have removable rechargeable batteries.
Heating Element (Atomizer)– a wire that heats up to a preset temp. It sits between the battery and the reservoir of liquid nicotine. The element needs to be in direct contact with the liquid when it is heated for the process to work. Every heating element will eventually burn out and need to be replaced, just like a light bulb.
Basic Atomizer- drop a few drops of e-liquid directly on the heating element, also know as a drip atomizer.
Cartridge- used in basic rechargeable electronic cigarettes. Prefilled and disposable, one time use usually.
Cartomizer- is like an atomizer, but with a poly-fill blanket wrapping the heating element. This allows the element to soak in the e-liquid at a constant rate and hold much more e-liquid than an atomizer.
Tankomizer- Some cartomizers have holes punched into the sides to allow them to be placed in a larger tank full of e-liquid. The e-liquid seeps into the holes soaking the poly-fill.
Clearomizers- have a heating element that is wrapped around a wick. The wick is long enough to draw the e-liquid from the outer reservoir into the heating element. These are popular due to the cheap cost and ease-of-use. Just take the mouthpiece off and fill tank directly.
