The battery sends a current through the coil of resistance wire (inside the tank) which has been wrapped around a wick or cotton which is gently heated to evaporate and turn the saturated e-liquid to vapour. 

How often can I vape? 

As often as you like – there are no rules. Generally your body will tell you when it's had enough nicotine as you will naturally stop craving it.

What am I actually inhaling?

Vapour made from evaporated Propylene Glycol, Vegetable Glycerine, flavourings and (if applicable) nicotine. It is essentially 66% water with the rest made up of the above ingredients.

How are e-liquids made?

Mixing and steeping - Propylene Glycol, Vegetable Glycerine, flavourings and (if applicable) nicotine.

How much nicotine is e-liquid? Are there nicotine-free versions available?

Nicotine is calculated as a proportion of the e-liquid. So if you have a 10ml bottle of 12mg nicotine – the percentage of nicotine in that bottle is 1.2%, totalling 12mg. Usually e-liquids come in the following order of nicotine strengths 24mg, 18mg, 12mg, 6mg, 3mg and 0mg (zero nic) – So yes, you can still vape liquids without any nicotine.

How do I refill a Tank?

Generally refilling your tank is an easy process. Depending on the device you are using, the method may be slightly different. On the basic starter kits, you simply remove the top (also known as a Drip Tip or the mouth piece) and send the liquid into the tank.

Other tanks require you to unscrew the base and refill the tank from the bottom. It is important to avoid the middle part of your device because that is the chimney to your mouth piece and you do not want e-juice spilling out as you attempt to re-fill. So always aim for the sides of the tank or where appropriate depending on your product.
