What is an e-cigarette?
An e-cigarette is an electronic device that vapourises e-liquids to simulate smoke inhalation. They were first invented in 2003 as a healthier alternative to regular combustion cigarettes, and have since taken over the smoking world – in 2015 there were approximately 2.2 million vapers, compared to 8.8 million smokers. This number is only going to rise as we now know they are at least 95% safer than cigarettes.
The e-cigarette usually consists of three main components: the tank (or clearomiser), the battery (or ‘mod’), and the coil (or ‘atomiser’), which is made up of metal wire and cotton. The battery powers the coil, which vapourises the e-liquid which is stored in the tank.
They create a sensation similar to smoking when inhaled. The user can choose to inhale e-liquid containing nicotine, of which there are varying strengths, without the negative effects of every other ingredient in tobacco. Similarly, e-liquids can contain zero nicotine.
What are e-liquids?
E-liquids are made up of four key ingredients: propylene glycol (PG), vegetable glycerine (VG), nicotine, and flavouring.
The PG is the carrying agent, meaning it carries the nicotine and flavourings to the user. It has no flavour and is free flowing, however it can dry out the throat and mouth.
VG also carries nicotine and flavourings but is a sweet and thick substance, meaning it is much smoother to inhale and produces thicker vapour.
E-liquids often contain a ratio of PG/VG, where higher VG blends provide thicker and smoother vapour (perfect for higher powered devices) and higher PG blends provide more intense flavour and a stronger throat hit (perfect for low powered, mouth to lung devices).
Types of E-Cigarette
There are many types of devices and batteries, such as:
- eGo style batteries and tanks
- Variable voltage devices and sub-ohm tanks
- Mechanical mods and rebuildable atomisers
All batteries are measured by capacity, in milliamp hours or mAh. As an example, a 1000mAh battery would provide 3-5 hours of battery life and a 1600mAh battery would provide 5-9 hours of battery life.
- eGo style batteries and tanks: These are the most basic products and are suitable for people just starting vaping, and all mouth-to-lung vapers (same sensation to smoking) who prefer an easy-to-use device. They contain an inbuilt battery and our ones range from 650mAh up to 2200mAh. They utilise only one button, which you press 5 times to turn on/off. The voltage (and wattage) is fixed so the power cannot be turned up or down. eGo Style tanks fit flush on eGo batteries, and are above-ohm, meaning they produce little vapour and are suitable for mouth-to-lung vapers. Check out our starter kits to see what eGo devices we have to offer.
- Variable voltage devices and sub ohm tanks: The majority of devices on the market are variable voltage, however some incorporate in-built lithium batteries and some use external, dry-cell batteries. Variable voltage means the power output can be adjusted to the user’s preference. They usually have in built lithium batteries which can range from under 1000mAh up to over 5000mAh on some long-lasting devices. A lot of mods will take external dry-cell batteries that can be recharged via an external battery charger. This is often a more sustainable option as when the batteries get old they can simply be replaced with new ones and the mod can continue to be used, rather than having to be thrown away. Sub ohm tanks utilise loew-resistance coils, meaning more power can be put through them, producing more vapour and intensified flavour. They are often used by more experienced vapours who prefer direct lung inhalation and the ability to customise their vaping experience. A lot of variable voltage mods now incorporate temperature control, meaning the device reads the temperature of the coil as it is heats up and adjusts the power output accordingly, to avoid dry-durning and extend battery and coil life. Check out our sub ohm kits, mods and sub-ohm tanks to see what's on offer.
- Mechanical mods and rebuildable atomisers: Mechanical mods are very simple devices but are mostly used by experienced vapers due to safety hazards. They are metal tubes that house a dry-cell battery, and when a spring-loaded part of the mod (usually at the bottom) is pushed towards the battery to create a full circuit, the power from the battery is channelled through the 510 connection and into the coil, vapourising the e-liquid. These devices can be dangerous if you do not understand ohm’s law. You must calculate the resistance of the coil needed to work in conjunction with the mech mod in order for it to not overpower the battery and cause it to explode. Rebuildable atomisers are often used in conjunction with mechanical mods - this means the user builds their own coil to their preference of resistance, temperature control options and flavour and vapour production.
All lithium batteries can explode. Luckily, most devices are regulated and carry a host of safety features meaning you can vape safely. However, if using dry-cell batteries (especially with mech mods) there are a few precautions to take to ensure the safety of you and your batteries.
- Only buy quality batteries from reliable sources. We stock Sony, Samsung and LG batteries.
- Use a high quality charger. Smart chargers offer more safety features meaning you don’t have to worry about the batteries overcharging and overheating.
- Store your batteries properly. This is absolutely vital to avoiding a serious accident. When the batteries are either not in their charger or in your device, keep them in a plastic or non-conductible case. If they come in contact with metals they can be fired, leading over overheating and exploding.
- Know your ohm’s law. When using dry-cell batteries with mechanical mods, ensure the resistance of the coil is suitable for the battery you are using.
What should I buy?
We offer a range of products for all types of vapers, ranging from starter kits for people just switching from smoking, up to high powered, versatile mods and tanks/rebuildable atomisers for experienced vapers.
If you are looking for an experience similar to smoking, we recommend buying a low powered kit for mouth-to-lung vaping. These kits range from roughly £25-£40 and are a perfect way of getting used to vaping as you quit cigarettes.
If you have been vaping for a while and are looking for something more customisable and powerful, we offer sub-ohm kits from roughly £35 (for basic sub-ohm starter kits) up to over £100 for more complex, high end vaping kits. You can find our full range of vaping kits under ‘kits’ on the main menu.
