Not all electronic cigarettes LOOK like a real cigarette, in fact most of them look like small pens with red, orange, blue or green glowing tips. They are easily distinguishable from a real cigarette though by a few factors aside from appearance.

There is no smoke. Smoke requires combustion and the burning of a material. E-Cigs do not burn or make flame. They heat a metal coil to bring a liquid up to vapourising temperature.

Vapour does not linger like Smoke does. Tests have shown that most amounts of vapour dissipate within seconds while smoke lingers for upwards of a half hour to an hour

Smoke smells badly. Vapour smells of nothing or faintly of the liquid flavourings, which consists of fruits, deserts, and fresh unburned tobacco smells (fresh tobacco).

The e-cigarette is composed of a few parts:
The cartridge or cartomiser is the part of the cigarette that allows the liquid to be absorbed. Sometimes you may need a drip tip in conjunction with with a cartomiser.
The atomiser or cartomiser is responsible for heating the liquid to be vaporized.
The unit is powered by a battery. There are automatic batteries which require you to puff in order for the atomiser to be activated. Manual batteries require a button to be pushed to activate the atomiser.
