Why does the E-Liquid sometimes change colour?

An e-cigarette is a nicotine delivery system which promotes an alternative way to administer nicotine via a battery, liquid container and coil. The battery unit usually has an in-built lithium-ion battery, which is rechargeable and this powers the device. Entry-level electronic cigarettes have an internal battery but more advanced devices have a removable battery which can be changed once it is no longer holding charge. The liquid holder is usually referred to as a clearomizer or tank and contains a heating element within called an atomizer (coil). This is powered by the battery and heats the E-Liquid which once inhaled produces vapour. For more information regarding each of these components please refer to the specific.

What is the cost?

The costs of electronic cigarettes vary depending on the type. Most beginner kits range from £20-£30, intermediate kits usually cost between £40-£60 and advanced kits costs £60 upwards.

In terms of the maintenance cost, this is relatively low as the only items that need to be purchased in the short-term are atomizer heads (if you have a replaceable clearomizer/tank) and E-Liquid.

Typically, atomizer heads or coils as they are sometimes referred to, last approximately two weeks. This is all dependent on frequency of use and the battery voltage. The higher the voltage the less the lifespan of the atomizer head will be.

What are the ingredients in eLiquids?

  • All E-Liquid consists of Vegetable Glycerin, Propylene Glycol, flavourings, nicotine and in some cases a colouring
  • Some Juices are 100% VG which means they contain no Propylene Glycol.
  • Max VG does not mean there is no Propyene Glycol in the juice

Propylene Glycol (PG):
- Propylene Glycol is high quality pharmaceutical grade, in combination with the nicotine and flavours this gives you more of a throat hit.

Vegetable Glycerine (VG):
- Glycerine helps to produce more vapour and holds more flavour. VG is thicker in

Is nicotine harmful?
There is much debate about nicotine, but on it’s own nicotine has never been shown to be harmful. Much of the negativity surrounding nicotine stems from it’s combination with tobacco cigarettes.

Is nicotine harmful?

There is much debate about nicotine, but on it’s own nicotine has never been shown to be harmful. Much of the negativity surrounding nicotine stems from it’s combination with tobacco cigarettes.

What nicotine strength should I choose?

As a beginner vaper, we would recommened 12mg. This isto mimic the harshness of a cigarette and also to provide you with a similar amount of nicotine that you would get from a cigarette.

Are these suitable for vegetarians?

Yes, all our products are suitable for vegetarians.

Why does the E-Liquid sometimes change colour?

When some e-liquids are exposed to air and light they sometimes change colour; this is perfectly normal. If the E-Liquid in your tank turns into a dark brown/black colour, you may need to change your tank or replace the atomizer head in the unit (if it is a replaceable clearomizer).

How long does a 10ml bottle of E-Liquid last?

A 10ml bottle should last you approximately 5-7 days, this is for an average user. A standard clearomizer/tank has a 1.6ml capacity and this often lasts a whole day for the average user.

My battery won’t charge?

If your battery is not charging it may be due to a number of different factors. Firstly, ensure that the charger you are using is the correct charger for the battery. We recommend that you only use compatible chargers from our website to ensure that they work correctly and safely. Next, make sure that you are charging the battery the correct way. Some batteries are charged via the top connection (510 charger), others charged from the bottom via a micro USB. Mods that take external batteries require an external charger for the battery cells., although some also have a micro-usb port.

My battery won’t turn on?

Firstly, make sure that your battery is charged significantly before using it. The batteries we send out do have a charge in them but it is possible that a battery can have lost its chaege.

Different devices have different methods to turn the battery on. The most common ways to turn the battery on are as follows:

Click the power button rapidly three times
Click the power button rapidly five times

If none of these methods work please refer to the specific product page on our website or give us a call on 020 3475 4885 or email

Which clearomizers/tanks are compatible with my battery?

Batteries or Mods are either 510 or eGo compatible. On a 510 threaded battery you can only use a ‘510’ clearomizer/tank. An eGo clearomizer can be used but you will need an adapter -

What is a Passthrough battery?

A passthrough battery gives you the option to charge and vape simultaneously. These batteries usually have a charging port at the bottom of the unit.

How long do batteries last?

Below are averages for different size batteries, these approximations refer to continuous use (non-stop vaping).

1000mAh battery: 3-5 hours
1600mAh battery: 5-9 hours

Note:Above approximations are for a fixed voltage of 4volts, turning the voltage higher will give less battery time. Conversely, lowering the voltage will increase battery life.

What is the lifespan of the atomizer and how do I tell it needs replacing?

Atomizer refers to the atomizer head that is in all clearomizers and tanks. The atomizer head refers to the element, which is heated when the battery is activated and this is responsible for producing the vapour.

Typically atomizer heads last for about two weeks, but this is not the case all the time. As they are very fragile they can stop working after a few days if they are used excessively or if the wattage is too high. All atomizers have a Dead on Arrival warranty, this means that as soon as you receive the product you need to test it to see if it works, as soon as it works the warranty period ends. Atomizer heads are referred to as disposable goods and are not meant to last longer than a few weeks.

The majority of clearomziers/tanks we sell are replaceable units; this means that the only part that needs to be changed within the unit is the atomizer head. You can tell if the atomizer head needs to be replaced when there is a significant lack of vapour or if you get a burning almost smoky taste.

My clearomizer/tank is leaking?

This could be for a few reasons. It could be that there is too much juice in the tank, or perhaps the device hasn’t been screwed on properly. Careful inputting of the atomizer head will help.

Why are there different resistances?

Different resistances for different volume and strength of vapour produced. More power means more vapour which should also mean more flavour.

Can I use the same clearomizer/tank with another liquid?

Yes you can, but it is recommended that you clean the clearomizer/tank meticulously to remove the former flavour. After a few vapes, the former flavour should disappear. If it does not, the coil may be compromised.

My clearomizer is not firing/working?

I am not going enough taste/vapour?

This could be because the power setting is too low on your device, it could also be that the device you’re using it not set-up correctly for great flavour and vapour.

What are rebuildable atomizers?

Completely rebuildable atomizers are primarily aimed at advanced users as RDA’s are intricate to use. We would not recommend using these products if you are a beginner vaper as they are for those with a good knowledge of e-cigs only. Essentially, a rebuildable unit has two posts (some have more), one post is positive and the other is negative. In order to get the unit to work a coil needs to be created that goes from the positive post to the negative one. Within this coil there needs to be material that can absorb E-Liquid: Cotton. Both the cotton and the wire that is used to make the coils are available in varying grades of thickness.

Mechanical and Non-Mechanical Mods

Mechanicals Mods are in essence electronic cigarettes stripped to its ‘barebones’. These mods contain battery cells that when activated via a switch, complete a circuit that fires the atomiser which is attached to the mod. These devices are for advanced users only.

Why should I buy a mechanical mod?

Mechanical mods are very versatile and are great to use with rebuildable atomizers (where you have to build your own coils and wick). You can ger reliable, high amounts of power fed to your chosen RDA to promote flavour and vapour in ways that clearomizers/tanks are unable to. Mechanical mods are not aimed at new users, as they can be dangerous if used inappropriately.

Which battery cells can be used with MODs?

Battery cells are available in 3 sizes, 18350, 18490/18500 and 18650. These are the types of battery, which are used with mods. They can be high-powered and long lasting. They provide external power to your chosen device.

How should I maintain the products?

With all the products we sell, we recommend that you treat them with care. Batteries need to be stored appropriately and safely as they can be dangerous if misused.

For example, battery cells should never be stored in your pocket with other metal objects like coins or keys as this can short out the battery and cause a hazard. Battery cells should be stored in a safe area away from metal objects or in a plastic storage container.

I am not happy with my products, what do I do?

    - 20/04/2017
    I've had this tank for quite some time now, using 0.5ohm and 0.2ohm coils. I also own approximately 8 other sub ohm tanks ........ from RBA / RTA, Uwell Crown to TFV12 and this tank I still use when i'm on the move along with a Cool Fire 4 plus mod. Every flavour tastes as it should, its economical and it doesn't leak ! Great clouds for a 0.5 and still great flavour on a 0.2. I would urge anyone and everyone to have one of these because it never fails........ EVER! At the prices they are at now you should be stocking up and get yourself plenty of coils, not because you go through them but because you will always come back and use this tank. On the issue of coils, I have never had a problem with longevity, ive never had a dry hit and all my coils have lasted a very long time considering I use it in my car everyday and whenever im just out and about. I would say at least getting 30 tanks out of one atomiser which in my book is extremely good. Hope this helps you guys. Like I said I have at least 8 tanks and this is the only one that can tick every box, its not the best at anything but its the best at everything in one well rounded and well built tank.

    I've had this take since last november swapped the coils a few times. I have found it pretty good for clouds and for £20 you're getting what you pay for. I have knocked mine around alot aswell and it has never broken on me. The 4.5ml tank will last you all day without refilling. On the down side, Higher nicotine liquids that I know are not usual y used in these type of atomizers do not run too well. My tip if using a higher nicotine liquid in this tank would be to turn air flow down to minimum and have your watts around 15-20 and use it like the very basic vape pens that dont have much air flow. Overall its a great tank and i would recommend it to any beginner vape.

    Amazing nice sized tank one of the best i have personally sub ohm tanks ,just one small change from plastic one the air flow adjuster tightened opposite way,so it bit in instead of slackening from mod...but just slacken before adjusting flow...still top tank...

    Can't understand the comments on here, yes the tank is decent but the coils are a joke. I'm replacing mine every week, sometimes twice, I spent less when I smoked
  • Review by Sub-ohm
    - 15/02/2016
    Preferred tank over all others, used to be into Kanger subtank's however after a recommendation i switched to this and i am very pleased. been using it for months with 0.2 ohm coils and been putting out clouds between 30 watts and 75 watts on multiple different systems. For chain vaping i would suggest around 30 watts to let the coils re-soak. For £20 you cant go wrong

    This is a fantastic workhorse of a tank large capacity easy change coils and no leaks. Good flavour and big clouds. 0.5 coils handle 35w no probs and last a fair while. Overall a nice tank for the price.

    Great tank, really easy to use, great clouds and great taste
  • Review by Rod
    - 02/01/2016
    For once a tank that does not leak or spit that does what it is supposed to and coils that are of good quality too. Had bad experiences with Kanger and Aspire before this one.

    Very, very impressed.

    Don't let the price put you off this excellent tank, as far as stock coils go this is way better than the Kanger Sub's, much more flavour and the coils last ages.
    Only one bad side is no RBA deck but with the excellent flavour and longevity of the coils and price this is by far a great tank, I prefer this to the Kangers!

    - 24/12/2015
    I bought the iSub G as my first sub-ohm tank after seeing a friend with one. Wow - I'm not disappointed! This tank is fantastic. It gives superb flavour with no harsh throat hits even at 35W. I've sampled one or two other sub-ohms since and, as yet, nothing compares. No gurgles, no harsh hits, no leaks and a plenty of flavour with tons of vapour production. You really need to try one.

    I own a few tanks but this is my fav its easy to change coils around, does not leak, feels good and the juice taste great in this. Its way better then my kanger mini
  • Review by Dan
    - 16/10/2015
    What a great tank for a very reasonable price, the airflow is really good on this compared to my kanger mini tank and the flavour is lovely,
    It cools the vapour down perfectly and produces awesome clouds.
    I really love the drip tip on this, doesn't get hot at all and gives you a nice open draw.
    Like the design and it's easy to fill and change coils over, No leaks.
    Coils are reasonably priced aswell,
    Personally this tank has blown me away and for the price of the tank and the price of the coils it's a winner.

    Just starting vaping or thinking about getting this tank as a toy Then go get it. It's 20 notes well spent and go straight to 32.5 Watts with a good juice and your all-day vape is sorted.
  • Review by Steven
    - 08/07/2015
    This was my first Sub ohm tank, and at first, I thought it was just good.

    I recently bought the Kanger Subtank Mini V2, and comparing them side by side, this Innokin is just miles better. The flavors are pronounced, without any added harshness. In comparison, the Kanger tank feels restricted, and no matter what juice I use in the Kanger, they all give me a nasty throat hit/ harsh hit.

    The vapor from this feels full of flavor, yet airy, and very cool. Even my friend commented how cool the vape is. Long, back to back hits does heat the tank up a bit, but the huge airflow keeps the vapor decently cool.

    Whenever I buy new juice, I use this tank as I know it always produces the best flavor.
    Get it.
