An E-NI, otherwise known as a personal vaporizer, is a battery-powered device that provides inhaled doses of nicotine by way of a vaporized solution. It is an alternative to smoked tobacco products, such as cigarettes, cigars, or pipes. In addition to nicotine delivery, this vapor also provides a flavor and physical sensation similar to that of inhaled tobacco smoke, while no tobacco, smoke, or combustion is actually involved in its operation.
An E-NI usually takes the form of some manner of elongated tube, though many are designed to resemble the outward appearance of real smoking products, like cigarettes, cigars, and pipes. A common design is also the "pen-style", so named for its visual resemblance to a ballpoint pen. Most E-NI's are reusable devices with replaceable and refillable parts. A number of disposable E-NI's have also been developed.

Battery - The main body of your E-NI. This is rechargeable in the non-disposable electronic nicotine inhalators. Charging typically takes between 1 and 3 hours depending on the model, and will give you power typically for around one hour of heavy vaping, up to 4 or 5 hours of very light vaping, again depending on the model being used.
Atomizer - This part converts the nicotine liquid into a vapor, much as a smoke machine by principle, by heating up a small element.
Cartridge or Cart - These are plastic mouthpieces (disposable) which contain a deep well, filled with nicotine-liquid soaked wadding.
E-liquid or e-juice or juice - This is the nicotine liquid which makes your electronic nicotine inhalator work. You can buy various strengths from 0 to 36 mg and refill your 'disposable' carts with it.
Analog - The term vapers give to tobacco cigarettes! Analog versus digital!
