Amps and Amperage
The amps or amperage refers to the flow of electric charge through a medium of specific resistance. It can be considered as a way of measuring how long a battery will be able to deliver the voltage charge. A typical battery will supply 2000 milli Amp hours.
An Analog is a slang term for a traditional tobacco cigarette. It’s an ironic way of differentiating an e-cig from an ‘analogue’ smoke.
This is an acronym for Anti Nicotine and Tobacco Zealots. They are typically members of anti-tobacco groups, but also unaffiliated individuals who hold strong, unscientific beliefs about the dangers and nature of nicotine, and who collude in keeping the public in the dark about the safety of non-smoked tobacco products relative to smoking.
The atomiser is the heating element of the electronic cigarette it causes e-liquid to turn into a vapour. Contains one or more coils of resistance wire, and comes in a multitude of formats depending on the device.
An ampere is the international system of units unit of electric current. Currents passing through vaping products are in the Milliamps (thousands of an amp) range.
Is a feature on some vaping devices where the vape is generated when the user puffs, rather than by pressing a button.
All Day Vape
Some Vapers have an eliquid or eliquid/device combo which they use ‘all day’. Many Vapers will have other vapes for different circumstances.
APV: Advanced Personal Vaporizer
An APV is a vaping device with high battery capacity and advanced microelectronic features such as the ability to vary the voltage or wattage, or the ability to monitor puffs taken.
AWG: American Wire Gauge
A North American system of measurement for the diameter of electrically conducting wireBACK TO TOP
The battery is the power source for an electronic cigarette. Although in this context “battery” often refers to the whole ‘power unit’ of an e-cigarette or eGo type device (i.e. including the switch, LEDs and threading for cartomiser or Tank). Many other batteries are used in Mods/APVs
B&M: Bricks & Mortar
Sometimes known as “vape stores”, these have sprung up across the UK and other parts of the world in recent years.
BCC: Bottom Coil Changeable
A Bottom Coil Changeable is a tank design in which the coil sits at the bottom (battery end). The coil is housed in a protective unit which is replaced regularly.
BDC: Bottom Dual-Coil Cartomiser
Similar to the above, but utilizes twin-coils for greater performance.
Empty (i.e. not prefilled) cartomisers which vapers purchase to fill with their favourite e-liquid
A mod in a box shape! They have a number of advantages over cylindrical devices, such as the ability to contain additional functionality in a configuration that only a cuboid shape can permit. Box form devices are preferred by some vapers.
Typically found on older devices or on dripping atomizers, the bridge is a ‘U’ or ‘V’ shaped steel mesh covering the heating coil. The mesh is covered by an absorbent material designed to wick e-liquid from a cartridge filler to the heating element.
The cartomisers combine a heating element and e-liquid delivery system into a single unit
This is a component of the first generation cigalikes which were 3 piece devices comprised of a battery, an atomizer and a cartridge containing an e-liquid saturated filler which was inserted into the atomizer. The cartridge is considered by many to be old technology at this point.
CASAA: Consumer Advocates for Smokeless Alternatives
A consumer-led, volunteer Tobacco Harm Reduction organisation which campaigns for the truth to be told about the relative safety of smokeless tobacco and vaping products compared with smoked tobacco.
A CE 2 device has the heating element at the top of the device with wicks that hang down into the juice. The e-liquid is drawn up the wicks to the heating element.
Once referred to as 'mini', e-cigarettes which resemble cigarettes are often now referred to as cig-a-likes or cigalikes. This is to differentiate the category, which is commonly found in places where smoked tobacco is sold, from the rest of the vaping devices, which are found online and in dedicated vape stores.
Many different chargers are provided for use with vaping products. Some are classic battery chargers for rechargeable batteries; some are designed for the specific e-cigarette, typically with either a screw-threaded or a USB attachment. It is important to only use the charger supplied with the vaping device. Using incorrect chargers has been implicated in some battery fires.
The Clearomiser is a tank system for containing and vapourising e-liquid that typically utilises a replaceable head or coil. This makes them more cost effective to maintain. The term originally referred to a larger (transparent) cartomiser which did not require filler material, but is now used generically to describe tank systems which are transparent or feature ‘viewports’ (such as the EVOD or CE3 etc.) which allow the user to see how much e-liquid remains in the tank. Clearomisers come in many different formats including top coil (like iClear16b) and bottom coil (like the Gladius). They feature either a single or dual coil system and many have adjustable airflow systems.
The coil is the element of the electronic cigarette. They are made from either Kanthal or Nichrome wire which heats when current is applied to it, and vaporises the e-liquid. Coils are configured in myriad different ways, and are of different lengths and thicknesses. Many vapers choose to ‘build’ their own coils according to their own preferences. The overall output of a coil is subject to ohm’s law.
Historically many different connection types were available. Most common were the 510, 901, 808, and 801. Recently the 510 connection appears to have become the universal size and most new devices are 510 compatible making it the best choice for those like to have the option of using different tank and battery combinations.
A cut-off is an automated protective feature that some vaping products utilise to cut off the power to prevent overheating and the associated dry-puff.
A first generation 'all-in-one' e-cigarette designed to be fully disposable. Once it's spent, it is discarded. Very popular with first timers but can’t yet complete with the new 2 nd generation devices.
Dripping is a technique whereby a dripper (usually a pipette) is used to drop small amounts of e-liquid directly onto the atomizer. This is in contrast to the typical e-liquid in a tank or filler material being wicked to the atomizer. Another form is known as direct dripping, the e-liquid is dripped onto the atomizer coil itself, as opposed to on the wicking material surrounding the coil.
The drip shield was designed to prevent e-liquid spilling onto the device as a result of over dripping.
A drip tip is a mouthpiece which enables e-liquid to be dripped through it onto the atomizer. Drip tips are also commonly found on clearomisers and are typically replaceable. They come in many different styles, materials and colours.
Drip On-Demand (DOD)
DOD systems are designed to allow the semi-automated dripping of e-liquid onto the atomizer coil/wicking. In some respects, this is the holy grail of vaping product design.
The DNA is a series of integrated power regulating chipsets and display screens originally produced by Evolv. They are often used by modders, but are also used in commercially available offerings.
If there is not enough e-liquid in the device, the remaining e-liquid may overheat causing a dry-puff. Almost all new Vapers will experience this nasty phenomenon a few times in the early days, but it's easily avoided by ensuring sufficient e-liquid is present.
Do It Yourself (DIY)
Many of the innovations in vaping products have come from hobbyists DIY’ing their own devices and e-liquids. ECF has an active community of DIY’ers, but it's not for everyone - there are risks involved, particularly with handling concentrated nicotine e-liquids.
E-Cigarette is a generic term referring to a device used to vapourise e-liquid. They are typically made of three parts, a power source, a heating element and an e-liquid delivery system. The power source heats the element, whilst the e-liquid delivery system supplies the e-liquid to the element. Upon contact the e-liquid vapourises. This vapour is then inhaled. Depending on who you talk to, 'e-cigarette' is either the name for the whole category of vaping products, or refers to those devices which resemble tobacco cigarettes (see Cigalikes). Also, E-cigars, E-pipes, E-hookahs: all terms describing vaping versions of traditional tobacco products.
E-liquid is the liquid which is vapourised by the heating element in the atomiser. The subsequent vapour is then inhaled which creates the sensation of smoking. It is typically composed of 4 ingredients, a base of varying ratios of propylene glycol and vegetable glycerine, nicotine and flavourings.
The first mass-produced 2nd generation vaping product. Because eGo was never trademarked it is sold as a generic product ‘style’ by many suppliers. The original eGo device was produced by Joyetech, but all the major manufacturers have a similar device in their inventory.
ECF is considered one of the first online community for vapers and still the most popular and active. ECF has played a central role in the development of vaping culture and the vaping industry.
A silica braided wicking material created for use with rebuildable atomizers. It is preferred because of its excellent wicking and its heat-resistant non-toxic properties.
Filler material is found in cartridges and some cartomisers. The material is designed to absorb the E-Liquid which allows is to act as both a binder for the e-liquid (so it doesn’t leak) and a wicking material to deliver the liquid to the atomiser coil.
Flooding occurs when too much e-liquid is delivered to the atomiser or cartomisers. This causes a gurgling sound and results in poor vapour generation.
The genesis re-buildable atomiser was one of the first commercially available. The name is used generically to refer to re-buildables with specific design features.
A tank system manufactured using Pyrex glass instead of polycarbonates. This makes the tank more resistant to heat allowing the use of e-liquids known to reach high temperatures when vapourised. It is generally agreed that these tank systems are safer than plastics.
Gooseneck is a flexible extension part for any device using 510 atomizers. The Gooseneck is designed to move the device you are using further away from your face as a safety feature. It also allows you to vape comfortably in various, otherwise awkward positions as well.
GRAS (Generally Recognized As Safe). This applies to food and cosmetic ingredients only and not to inhalable products since they’ve not been tested for inhalation safety. Regardless, GRAS ingredients should only ever be used in e-liquids.
The heating coil is part of an atomiser that acts like the element in a kettle. It is generally a piece of nichrome or kanthal that is wrapped around a wick. As the current flows through the coil, the coil heats up and vapourises the E-Liquid.
High Resistance Battery
High resistance (HR) batteries also known as high voltage (HV), have more power under the hood, which results in higher heat and greater vapour output. They're also known to create a more intense flavour. The only problem with the high resistance battery is that it puts a lot of wear and tear on a standard or low-resistance atomiser. In fact, if you use a high-resistance battery with a low resistance atomiser you will significantly reduce the life of the atomiser. You should use high resistance batteries with high resistance atomisers. The same can be said about very high resistance/voltage (VHR/VHV) batteries. Also keep in mind that the higher your battery voltage the more e-juice you're going to use
High Resistance (HR)
Atomisers which run at a higher resistance typically run cooler and drain less power from the battery.
This occurs when a rebuilt atomiser coil is not fully in contact with the wick. This results in uneven heating and causes parts of the coil to expand and contract at different rates, which wears out the coil much more quickly. H ot-spots can generally be identified when the coils are glowing, and an unpleasant burnt taste is created. When rebuilding coils it is therefore important to ensure the entire coil is in contact with the wick before use.
HV High Voltage HV Atomiser
High voltage atomisers typically use a higher resistance coil. Consequently because of Ohm’s law, lower resistance atomisers would run too hot.
Hybrid atomisers are a dripping style atomiser designed to allow greater performance by allowing e-liquid to be dripped directly on to the coils.
Hybrid Personal Vapourisers are designed to be seamless all-in-one devices. They have been developed in response to experienced vapers creating high performance devices from an uncoordinated mixture of their favourite components. Instead of looking thrown together Hybrid PVs look like sleekly engineered machine.
ICR BatteryThe term 'ICR' refers to a type of battery used in specialist E-Cigs. ICR batteries use LiCoO2 as a major component. However because of this they are considered to have a more volatile chemistry, generally lower amp limits and higher internal resistance than IMR batteries so are not as popular.
The term 'IMR' refers to a particular type of replaceable and rechargeable battery used in specialist E-Cigs. IMR batteries use LiMn2O4 as a major component. They have improved safety characteristics due to a less volatile chemistry than ICR, generally higher amp limits, lower internal resistance, and are designed for high drain devices (they are commonly found in rechargeable cordless power tools). However it is important to note that others have asserted that these properties are not necessarily the case and it depends on the manufacturer and model of the battery. Nevertheless IMR batteries are the type favoured by most advanced users.
Juice is a slang term referring to e-liquid.
Kanthal is an alloy composite wire which is one of the main types of resistance wire used as a heating coil in atomisers.
Kick is a circular chipset that boosts the power of any IMR cylindrical mechanical mod battery. This means the power output of the batteries can be regulated to suit the resistance of the coils.
Is a type of drip tip that rotates allowing the user greater flexibility over the angle at which they hold their device for vaping.
Tank systems can leak for a few reasons. The first is when too much juice is added to an atomiser or cartomiser. Next is due to refilling the tank incorrectly, i.e. getting liquid in the wrong part of the tank. Finally and most obviously, because the tank is broken. It is very important to fill the tank properly because if e-liquid leaks out of the bottom of the heating element and onto the battery, this can cause damage to the device. If the e-liquid comes into contact with the skin it is not a problem as long as it is washed off soon afterwards.
Li-PO & Li-Ion Battery
Batteries known as 'Li-PO' are the same as the ones marketed simply as 'Li-Ion', because the underlying electrochemistry is the same. In this case 'PO' stands for polymer and refers to the casing. Batteries found in mobile phones are generally Li-PO batteries and are typically contained in a thin rectangular casing. As battery technology develops 'PO' may well refer to a polymer electrolyte as opposed to the liquid electrolyte more commonly used today.
LR stands for low resistance. Low resistance atomisers or cartomisers have a lower Ohm rating than the standard devices resulting in the coil to get hotter more quickly and producing more vapour than their higher resistance counterparts. This produces a warmer vapour, with a stronger throat-hit that many prefer.
Milli Amp Hours are the rating of energy density in a battery. It describes how long (in time) a battery can provide a current for. An 18650 battery rated at 2600 mAh run at a setup draining 2amps will last for 1.3 hours on a full charge, for example.
Manual Devices or Batteries
Many vaping products require the user to manually press a button to fire the atomizer coils instead of activating through sensors detecting a 'puff'. This is preferential for many, as it allows the preheating of the coil prior to taking a puff creating a fuller vapour.
Mechanical Mod (Mech Mod, Mech PV)
Mechanical mods are devices in which there is no microelectronic circuitry (unless a Kick is added). Power output is controlled through Ohms law - that is to say, by combining battery voltage with specific resistance of the coil to create the desired heat.
Is the abbreviation for Milligrams, the amount of nicotine found in an e-liquid. Typical levels include 0mg, 6mg, 8mg, 12mg, 16mg, 18mg, and 24mg. Generally speaking, an average level of nicotine is around 18mg. Stronger e-liquids have been produced and are still available but due to new legislation, from 19th May 2017 20mg will be the strongest legally available liquid. It has been the convention for manufacturers to describe the nicotine strength of their e-liquid in terms of the number of milligrams (weight) per millilitre (volume) of e-liquid. Some manufacturers are now choosing to use percentages instead, as this is based on volume alone.
A smaller diameter coil, typically constructed by wrapping kanthal around a hanging nail or some such, and having the coil pushed together without space between wraps. See this ECF thread for a nice example.
One of the original styles of electronic cigarettes available, these generally are about the same size as a traditional cigarette and have the shortest battery life of any style. The mini is typically sold in big stores for the naïve user. They are now considered old technology and are not popular with typical vapers.
In the main, a Mod is a device created by enthusiasts looking for a better device than the mass produced devices. They wanted superior battery life and better vapour production. Consequently Mods typically use larger rechargeable, replaceable Lithium Ion batteries. As a result the devices no longer look like traditional cigarettes. Many mods will also allow the user to increase or decrease the voltage of their device to achieve optimal performance.
The term Modder refers, unsurprisingly, to an E-Cigarette user who uses Mods.
A multi-voltage device has predetermined voltage settings. This can vary from simple low, medium and high settings through to devices that allow the voltage to be set in 0.1v increments. The settings can range anywhere between 3.5v to 6.0v
Nichrome is an alloy composite wire which is one of the main types of resistance wire used as a heating coil in atomisers.
NicotineNicotine is a natural substance derived from the plant Nicotiana tabacum. The plant is part of the nightshade family which also includes tomatoes and potatoes, all of which contain nicotine. In doses of ~ 1mg nicotine in acts as a stimulant, while high amounts (50–100 mg) can be harmful. This stimulant effect is likely to be a major contributing factor to the dependence-forming properties of tobacco smoking.
NRTNicotine replacement therapy refers to medicinally licensed products designed to administer nicotine to the body by other means than smoking. Common forms of nicotine replacement therapy are nicotine patches (which transdermally administer nicotine) and nicotine gum (which orally administers nicotine). The nicotine is delivered slowly to the body thus reducing the dependence-forming properties of tobacco smoking.
A nickel–metal hydride battery, abbreviated NiMH or Ni–MH, is a type of rechargeable battery. Many say they are not suitable for vaping but technically this is not true. The main downside of NiMH batteries is that they deliver less voltage and current for their size and weight in comparison to Li-Ion batteries.
OhmThe Ohm is a measure of electrical resistance. Scientifically the ohm is defined as a resistance between two points of a conductor when a constant potential difference of 1.0 volt, applied to these points, produces in the conductor a current of 1.0 ampere, the conductor not being the seat of any electromotive force.
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. It is expressed by the following equation I=V/R where I is the current (amperes), V is the potential difference (volts), and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the resistance in this relation is constant, independent of the current. This means that the lower the resistance of a coil the more current can flow and therefore faster heating of the coil.
A passthrough device plugs directly into the USB port of a computer or charger and allows the user to continue vaping whilst charging the battery. Some users report better vapor production and/or flavour while using a Passthrough compared to their regular batteries.
PEG (Polyethylene glycol)Polyethylene glycol is a base carrier liquid used in e-liquids. It is the least common carrier liquid, generally more common in pre-filled cartomisers. It is said to present flavours better than other base liquids.
The Pen Style is one of many styles of electronic cigarettes available on the market. They often resemble a ball point pen in appearance.
Personal Charging Case (PPC)
This is a device that after charging is then used to charge E-Cig batteries whilst away from mains supply charging.
Personal Vaporiser (PV)
This name is used as an alternative to E-Cigarettes. It is usually used in reference to the more non-traditional style e-cigarettes (also known as Mods). The main reason being is that most vapers do not consider vaping as an alternative to smoking but a new method of consuming nicotine unrelated to smoking.
A Primer is a clear, unflavoured coat of propylene glycol, vegetable glycerine or a mixture of the two. It’s a substance that manufacturers use to soak atomiser wicks during the production process. The primer is utilised to prevent an atomizer from being used dry, this can burn the wick and create a permanent harsh, bitter taste. As you use the atomizer, the primer is slowly replaced by your own e-liquid. This should only take ~10 puffs but if that is not acceptable it can be removed by disconnecting the atomiser and placing it in a neutral-tasting alcohol such as high-proof vodka. After soaking, rinse with water to remove the alcohol to prevent the wick burning. Once the wicks are dry replace them and fill the tank with E-Liquid, and then leave to stand for 3 minutes to allow the E-Liquid to saturate the wicks.
Propylene Glycol (PG)PG is the most common refill liquid base material, normally used with 10% to 30% VG. It is virtually inert in the body apart from the fact it is a powerful bactericide. It can even be injected into the bloodstream without effect. Propylene Glycol has been researched for the last 70 years and it’s safety has been proven if consumed in any reasonable quantity. Because it is made from non-organic sources (via chemical processes) allergic reactions are seldom reported. As a base for e-liquid Propylene Glycol carries the flavour well and delivers a great throat hit.
Protected BatteryA protected battery has a small circuit board built into it to protect it from certain issues. For example, the circuit board can cut off the battery to prevent it from overheating if the user draws too long and too frequently. If a battery overheats it can damage the atomiser, causing them to have a significantly shorter life, or poor performance. On the other hand, they are not as much fun for modders who might be looking for a maximum power draw every time (see unprotected battery). Modders use devices with protection already built in so can use unprotected batteries which deliver the strongest hit. BACK TO TOP

An RBA is a rebuildable atomiser. These atomisers allow you to replace the wick or coil system. Replacing the wick is usually a procedure for advanced vapers as it requires the manual building of a wick and coil system and its installation into the rebuildable atomiser. However, those who take the time to learn how to do so never seem to regret it!
An RDA is a rebuildable dripping atomiser similar to the RBA but allow for the direct dripping of E-Liquid onto the coil providing awesome levels of flavour and vapour.
An RTA is a rebuildable tank atomiser similar to the RBA and RDAs but RTAs also have incorporated tanks which automatically feed the wick with E-Liquid removing the need for constant refilling.
The Ohm is the measure of electrical resistance by which all atomisers and cartomisers coils are categorised. The lower the resistance of a coil the hotter it will get with a comparative power using a high resistance coil. For this reason users will tend to use low resistance coils on the lower powered devices to prevent the coils burning out.
'Ribbon Coil' refers to the coil wire being flat instead of round. The primary difference between flat and round wire is the amount of surface area for a given volume. Using a flat wire for the coil increases e-liquid vapourisation because the larger the surface area of the wire the more e-liquid can be vapourised. This is why cooking stoves have flat tops, because there is more contact area between the heat source and whatever is being heated. Because of the wire’s flat shape, it is much easier to coil and cover the wick. Consequently, using a ribbon coil helps eliminate hot spots and drastically increases the life of your coil. When rebuilding an atomiser (RBA), avoid twisting your ribbon Kanthal when you are winding your coils. The one exception is at the positive and negative screw terminals where twists are unavoidable due to the ribbon wire needing to be flat (horizontal) against the screw head, as good electrical connections require good mechanical connections.
Smoke Juice is a slang term for e-liquid, juice, or e-juice. This is the liquid that is vapourised when using an electronic cigarette.
Is a term used to refer to an electronic cigarette. This term is commonly used because no combustion takes place and therefore no actual smoke is inhaled or exhaled while using an e-cig.
Is a kit that includes basic e-cigarette equipment. Typically includes everything needed to begin vaping. Most starter kits come with 1 or more atomizers, 1 or more batteries, and a charger.
Stacking is placing two batteries instead of just one like in a torch. Devices sold by VaperVapour have vent holes and protection already built in. However always use matched pairs of batteries.
Steeping refers to two processes. The main use of the term describes allowing time for the e-liquid’s flavours to mature and integrate before use, a similar process to allowing wine to breath. The other use describes giving a freshly filled tank time for the wick to absorb the e-liquid.
Is a coil system that has a resistance of lower than 1 Ohm. This should only be used by experienced vapers who fully understand battery safety and the potential dangers involved.
The tank is a component of a personal vapouriser that holds the e-liquid.
The tank system is a component that combines an atomiser and a tank. The convenience of this system is measured against the reported reduction of flavour and vapour production.
Lithium batteries can suffer from overheating generally known as 'thermal runaway' this is where batteries are used in unprotected devices and become very hot and vent off gas. Overheating or a fire within the electronic cigarette is usually caused by an internal short in the battery. Lithium-ion cells contain a separator sheet that keeps the positive and negative electrodes apart. If that sheet gets punctured and the electrodes touch, the battery heats up very quickly. All VaperVapour devices have built in short circuit protection to prevent this from occurring.
Throat Hit (TH)
Throat hit is the tingling sensation felt at the back of the throat when vapourising e-liquid that contains nicotine. Typically, nicotine is the main contributory factor in throat hit, as a consequence when a juice that contains zero nicotine is vaporised, there is no throat hit. However throat hit is also generated by other factors including the flavourings, the constituents of the E-Liquid base, the device voltage and the resistance of the coil.
Tobacco Harm Reduction (THR)
Tobacco Harm Reduction refers to using a safer version of nicotine consumption. Research has suggested that vapourising nicotine is the most effective means of replacing the nicotine consumed by smoking regular cigarettes.
Battery tube e-cig mods are the most common and most popular type of a modification. They come in all different sizes but always have a tube like shape. The Difference between tube and other PVs is that tube mods always have a replaceable battery inside the casing.
Unprotected batteries do not contain protection circuits. The circuits are designed to stop the battery from over-charging, over-discharging, short circuit and overheating. Unprotected batteries should only be used with devices with built in protection circuits.
Vape is the action of using an electronic cigarette. Since e-cigs actually produce vapour (rather than smoke) people refer to this as 'Vaping'.
A person that vapes!
A Vapour Cigarette is a term used to refer to an electronic cigarette. This term is used commonly due to the water vapor that is exhaled when using an e-cig.
Vapour Production is typically associated with juices. Indicates how much vapour is produced using an average inhale of an e-cigarette.
The act of consuming nicotine using an E-Cigarette
A vented Mod has vents which allow the battery to cool down during use preventing overheating and also allows the battery gases to disperse in the event of battery failure.
VG: Vegetable Glycerin
Glycerin is an alternative carrier liquid, though more commonly used as an
additive to PG liquids. It is more viscous (thick) than PG. If used as the sole
base material, it will need diluting with 10% – 20% DW (distilled water). Other
additions seen include alcohol and EM (ethyl maltol). There is little research
on inhalation. It is thought to be less inert than PG, and to be treated by the
body as a complex carbohydrate – that is, metabolized by being broken down into
carbohydrates and/or excreted. VG can be synthesized and made in a similar way
to PG and PEG from other chemicals, or it can be made from vegetable sources –
mainly coconut oil and palm oil. For this reason there are a very small number
of people who may have an allergy to a specific brand, of the same type of
allergy as that to peanuts.
Voltage specifies the amount of potential energy in a device. For example, most mods take batteries that store 3.7 volts of potential energy. We also talk about the amperage of batteries (typically something like 2000 mAh), this is the flow of electric charges through a surface: a way of measuring how long a battery will be able to deliver the voltage charge.
VV: Variable Voltage
A variable voltage device allows the user to specifically adjust the voltage level delivered to the coil. This is usually achieved via and button or dial. The variance of available settings depends on the device being used. To maintain optimal performance, if your device has a resistance meter (i.e. the iTaste MVP and VTR) it’s always wise to check before you start using a new brand of coil. Whilst all coils are rated for specific Ohms, this is only a guideline. Your device may detect a different level, which means the wattage or voltage must be adjusted to compensate.
VW: Variable Wattage
A variable wattage device allows the user to specifically adjust the wattage level used as well as or instead of the voltage. Based on Ohm’s law which states that watts (power) = voltage 2/ Ohms (resistance). Wattage is commonly selected via a button or dial. The variance of available settings depends on the device being used.
Typically, most people use variable wattage. It can take some time to correctly match the wattage with your coil. However, if your device has a resistance meter (i.e. the iTaste MVP and VTR have one) it’s always good to check when you start using a new brand of coil. Whilst all coils are rated for specific Ohms, this is only a guideline. Your device may detect a different level, which means the wattage or voltage must be adjusted to compensate.
VW and VV Settings Guide
The following table shows the approximate effects of resistance (ohms) of your coil unit on the voltage:
In terms of using a device with a variable wattage setting, the typical settings are from between 9.0 watts and 11.0 watts, dependent on the resistance of the head. 9.0 watts work with 1.8-2.1 ohm resistance heads, while 2.5 ohm resistance coil units perform better between 10.0 and 11.0 watts.
The most important thing to remember is to adjust your settings until you are getting the desired flavour and throat hit. Most vapers prefer a vapour which is warm and satisfying.
The watt is a measure of power or a measure of the amount of “work” done in a unit of time. This is expressed as a ratio: the charge multiplied by the voltage and divided by time. In terms of E-Cigarettes the wattage is a function of the voltage of a device and the resistance of the coil. So if setting a device using the variable voltage settings, you are telling it to send a fixed amount of energy through the circuit, despite of the resistance. Whereas, when you use variable wattage settings, you are telling your device how much “work” you want done, and letting it figure out the voltage needed to overcome the resistance.
You can think of the difference as being something like the difference between driving a car with an automatic transmission versus a manual transmission. Using a variable voltage device is like a manual transmission: you pick the gear, and then press the gas. If you can’t get enough speed, you have to shift to a higher gear (turn up the voltage). On an automatic, you put it in drive (select the wattage) and it adjust the power (voltage) as you step on the gas
In some devices such as the iTaste 134 and 134 mini, the wattage is adjustable as opposed to the voltage. Based on Ohm’s law the watts (power) = voltage 2/ Ohms (resistance) increasing the Wattage
A wick is a narrow piece of poly string that is inside of many styles of atomizers that delivers E-Liquid to the heating element. .BACK TO TOP
