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.

We recommend that you purchase one of our kits that come complete with everything you need to get started. In addition, we recommend that you purchase extra eLiquid with your kit to ensure that you have sufficient supplies.

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 support@ukecigstore.com

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 - http://www.ukecigstore.com/510-to-ego-adaptor-by-uk-ecig.html

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.

    - 22/04/2016
    Literally just bought this little thing and I'm overwhelmed with how amazing it is! Perfect drag configuring aspect, easy to change the wattage, no harshness in the hit but the nicotine still has effect... Fits into any pocket, easy to turn off/on with a clear display, can't fault it. Get yourself to the shop this is the best investment for someone wanting to give up right now

    great little mod to use for work with a kanger toptank mini. first time I have used uk ecig delivery was spot on
  • Review by Jordy
    - 29/03/2016
    Upgraded from a Kangertech battery, didn't like it as I'm very clumsy and dropped it all the time, the bottom where the wattage changes got very loose. None of these problems with the cool fire! Buttons nicely placed, nice to hold, fits in the hand well, much better than my long Kangertech battery cause I can actually put it in my pockets (woman's pockets are always way more shallow than men's for some reason) which sucks with bigger vapes. All in all very pleased with my cool fire which works well with my Kanger Aerotank2! Looks awesome in blue as well :)

    - 26/12/2015
    I purchased the Cool Fire IV two months ago as I wanted to get into Sub Ohm vaping. Paired with the Subtank Nano its the perfect combination.
    The battery usually lasts me a day or two and I'm a pretty regular vapour.
    You don't need to mess about with any extra batteries as you can charge the Cool Fire IV via a micro USB and vape at the same time if you'd like.
    Overall, I only have positive things to say about this device.

    Really good device , good to look at and has great features. Also quite cheap
  • Review by Steve
    - 11/11/2015
    This mod feels like it was made by a mainstream consumer electronics manufacturer - which is a good thing! Some that I've used feel like market stall / back of the van efforts, but this reminds me of the Sony MiniDisk player I used to own way back when (remember those?)

    These guys have put a lot of thought into how their users will use their product - and it shows! I'm a big fan of the shape; the curve sits nicely in your hand and IMHO puts more rudimentary box-shaped box mods to shame from an ergonomic point of view.

    The brushed aluminium looks and feels good and the colour contrast is superb. I went for black, but the brighter colours look great too, if that's your thing. The lanyard attachment point is a nice touch and stylishly done.

    The fire button is perfectly placed and the variable power buttons are easy to use. The small display is clear and gives me enough info. I like the fact the corners around the fire button are coloured green - yellow - red to show you the battery status even if you don't look at the main display after a draw. This also clearly shows battery status while charging.

    I've only had the Cool Fire IV a couple of weeks, but it has worked perfectly in that time, both for 'normal' tanks and subtanks. I've had no problems with cross-threading and the device detects the coils reasonably accurately (I think!) Just set the power and it works every time. More power = more cloud and bite, less = smoother draw. It just works.

    It sounds like I'm a big fan of this mod - because I am! I have no affiliation with Innokin, but praise where it's due!

    New to vaping as I've just given up the cigs after 27yrs. Had this & the curve vt40. Have to say the cool fire 4 is awesome paired with the kangertech mini. Constant vape at any setting. Can't put it down. Don't think I'll ever touch another cig again. Got the red, very well made. Looks worth much more than it cost.

    Buy you won't regret.

    Bought one after reading good reviews and was not disappointed. Works great with an isub g tank at 0.5 ohms. Not missed smoking one bit. Would highly recommend.

    - 23/09/2015
    Never used E cigs before, wanted to give up the fags, was recommended the coolfire IV by my local store, been using for 5 weeks and not touched a fag, really pleased, the device is very easy to use, as I've said I'm no expert but what I can say is that I would certainly recommend this device.
  • Review by Ricky Dean
    - 14/09/2015
    Fantastic bit of kit paired with an isub tank G. Good battery life, great for sub ohming. Best I've used. I upgraded to this from an eleaf 20w
  • Review by sandy66

    I've been using £10 vapes which were great for getting me off the cigs. I love this Cool fire IV, it gives a consistent vape every time. I don't know how I coped with the cheapos for so long. Highly recommended
  • Review by sabre
    - 15/08/2015
    Such a good looking device, curves are smooth. To touch is as soft as baby's skin. Easy to adjust the settings, easy to charge on a, vapes really good at all adjustments of the watts. Only fault I could find is on lower watts around 15 w it does take at lest 1sec to fire a charge. A way to replace the batterie and change is a downfall as it is enclosed and newer longer life batteries' supposly u could take the scews out and put one in urself. Overall a very good product. Hands down get one. Won't be disappoint.

    Cool! A very good device!
  • Review by Blinkz
    - 30/07/2015
    Bought this as an upgrade from my mvp 2.0, as I wanted something that could fire down to 0.3-0.2 and could reach a higher wattage, as I wanted to start building my own coils, this fitted the bill, it feels great in the hand (a touch smaller than my mvp) and the screen shows everything I need, one downfall is the size of the battery, doesn't last as long as my old device but I'm now using higher wattage so it's what I expected, great build quality, spring loaded 510 connection so all my tanks fit, and the price is an absolute steal, would recommend for anyone who wants to build and sub ohm but not quite ready for something too big or too pricey

    I bought this box 2 weeks ago and it is perfect.
    The shape of the box fits snug in your hand and the fire button is in the perfect position, ive had no problems with this at all.
    Been using the Aspire Nautilus on it and it works like a charm, I would highly recommend this to anybody, perfect box.

    Vapes extremely well, very smooth, long battery last me ages! Its very appealing light and nice in the hand. Would recommend
  • Review by Nathaniel
    - 03/07/2015
    Moving on from a petrol station epen, this was my first mod. I absolutely love it. The build quality is excellent. The anodised brushed finish is great to touch. 40w is a perfect start into vaping. Ohms reader, vape counter, adjustable in volts or watts, on/off switch; bargain.

    I started with an iSub 0.5 at 20w, the battery would last a day and a half. Now running an Atlantis V2 0.5 at 30w and get a days charge, vaping frequently.

    Could not recommend this enough.

    - 29/06/2015
    This is my on the go set up! The Coolfire 4 is small and powerful enough to deliver a smooth enjoyable sub ohm vape paired with the iSubG Tank! The battery lasts me a day and a half fully charged sometimes longer depending on how hard I hit it or how high I'm running it! Fits nice in the hand and its very well built!

    - 07/06/2015
    Just received this weekend my new Cool Fire IV. WOW! Love it. Its a great mini box mod, with all the innovative design and exceptional build quality that Innokin are renowned for. It does't disappoint in any way. Well done Innokin. In my opinion, you've got it just right.
    It fits perfectly in the hand. it feels like the quality product that it is. It performs extremely well with all my tanks. Weather it be my sub ohm tanks, or Aspire nautilus etc. The 2000 mah battery has a surprisingly impressive life. Easily lasts all day and beyond.
    To sum up. It's excellent. Superb value for money. Great build quality. Great performance. Its left the other manufacturers on catch up.
