An electronic cigarette as supplied by Ni-Smoke comprises two parts, a battery and a Cartomiser
The battery is approximately 6cm long, and contains a battery pack and circuitry that allows for its automated operation and charging. The battery contains the power needed to run the electronic cigarette.
The Cartomiser is the part that produces a vapour (hence the term vaping) that looks like smoke. It consists of a reservoir for e-liquid (that contains the flavour and the nicotine in a water base), a wick and a heater coil.
When you draw on the cartomiser, the battery circuit provides power to the coil, which heats up and vaporises the e-liquid in the wick. This vapour is then drawn through the mouthpiece and simulates the smoke from a regular cigarette.
The battery makes up the largest part of the e-cigarette and is charged using an AC outlet, Vehicle Charger, USB charger or PCC (Personal Charging Case). The Ni-Smoke battery life is dependent on usage. A heavy user will deplete the battery quicker than a light user and thus will need to recharge the battery sooner. You should expect to get approximately 300 charge cycles from your battery - when it is at the end of its useful life, it will be unable to hold a full charge. You will notice this as the battery will need recharging more frequently. If you are using a PCC the battery will continue to draw current and will deplete the PCC. Please dispose of batteries safely at local approved disposal points in accordance with WEEE regulations.
The Cartomiser contains what is termed as e-liquid or e-juice and contains propylene glycol(PG), vegetable glycerin(VG), water, mixed with natural and/or artificial flavourings and Nicotine. Flavours may contain trace of nuts.
Propylene glycol USP/EP (pharmaceutical grade) is the ideal carrier of a large variety of flavours and colours that give most of today's food and beverage their distinctive look and taste. Propylene glycol USP/EP (pharmaceutical grade) has been approved for use as food additive E 1520. In direct food contact it is mainly used as solvent and carrier of flavour or colour in food and beverage industry processes, to make drinks, biscuits, cakes, sweets thickener, clarifier and stabiliser in food and beverage such as beer, salad dressings or baking mixtures.
Glycerol is used in the food industry as a sweetener and preservative, especially in low fat foods. It's also used in flexible-foam production, and in nitroglycerin. In medical and pharmaceutical preparations, it's used in cough syrups and other personal care items.
