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?

UK ECIG STORE wants you to be satisfied with the products you are purchased as we pride ourselves on our levels of customer service. Please get in touch with our customer services team to discuss what the issues are.

What should I do if I think my product is faulty/not working?

    This is by far the best tank and coil set up I have ever used. Dont muck around with Kanger or Nautilus, you'll spend as much in the long run anyway. This is just an excellent bit of kit. Doesnt hammer your battery too much, easy to fill, not too big, coils last much longer than any Ive used before! Buy it
  • Review by Thomas
    - 06/06/2016
    The customisation options of this, sizeable, tank are second to none. RBA, Triple Coil occ, and quad occ are all included as well as a load of spares and 2 vape bands.
    The airflow options are also excellent, with both bottom and top airflow available for selection.

    Filling is a breeze, as it is top-loaded. Simply slide the top portion open to expose the tank and away you go! Be aware that the filling port is rubberised so you need not precisely try and drip through the tiny slot. Just poke the tip of the dripper through, and fill away.

    My only complaint with this tank, is however quite significant. It leaks. A lot.

    Dependent upon which coil you use (there have supposedly been manufacturing defects leading to batches that are really quite bad), the tank can start leaking just by looking at it funny. In my limited experience, the triple coil occ is the main culprit, but I have read reports that the quad and the RBA are just as bad. I guess it's all down to luck of the draw. Which is a pity, because the TF4-V is an absolutely amazing tank in every other regard.

    I still heavily recommend it, because when it doesn't leak, it's hands-down the best vaping experience i've ever had.

    This is a ok tank but make sure you have more than 40 watts or it won't work anywhere near as well as I only have 40 watts I'm not impressed but when I get a new mod it might be different

    Great tank, a little fiddly at times but overall great tank. Great flexibility, flavour and clouds (if you crank the watts) Make sure to use a higher vg and lower nic as this does deliver a lot of juice and I definitely noticed using difference using premium juices

    - 23/12/2015
    It's a beast it blows out the clouds , fantastic flovour and introduces you maybe building your own coils. The kit it good wit lots of replacements. It's sucks the juice mind and coils bit more pricey , still love it .
  • Review by Jeremy
    - 21/12/2015
    This beast really chucks it out. Great flavour and massive clouds. If you want to sit in a vapour fog this is the one for you. But beware it does drink the juice so make sure you have a good supply.

    It's a nice tank BUT it drinks juice and you get a lot of leakage from the top the crown tank at £19.99 is much better
  • Review by Andrew
    - 09/12/2015
    Where do I start? This tank is for the professionals. If you want to Vape your entire house out in 10 minutes whilst getting full flavour and no dry hits. This is the tank for you. I can't begin to describe the powerhouse this tank is, you'll need a high end device, I use my 150w sig, the coils are bordering on colossal, the juice guzzling and vapour production really is beyond anything I've seen so far in a tank, coils are pricey but totally worth it.
  • 4/5
    Review by Clare
    - 09/12/2015
    The TFV4 is a great tank with some even better coils. The quad coil is epic and creates great clouds, however, it does have a slight metallic taste to it when vaping I thought it would decrease over time but it hasn't. You can still taste the liquid flavour but it comes with a side of metal. But if clouds are what you're chasing then this is definitely a good buy.
    Side note : the TFV4 mini is practically identical, for something called a 'mini' it's almost the exact same size as the regular TFV4 and works exactly the same.
  • Review by Andrew
    - 05/12/2015
    As the other reviewers say, this is the best tank I have for flavour and clouds. I loved the Zephyrus but this beats it hands down.
    The drip tip is a little odd at first with it's aitlrflow configuration but now I like it too. Bear inmind the quad coils are 0.1Ohms so this wouldn't fire on my IPV D2. The other coils work though. No problems on my Sigelei 100W.
    Very big but I don't mind.
    I'm buting some more quad coils right now!
  • Review by Dan
    - 04/12/2015
    Really pleased with this tank, easy top fill design, coils are brilliant, loving the design of the drip tip which comes in handy when the vape gets warm just open the vents a little and it cools it right down, flavour is good.
    Awesome tank and kit for the price.

    This tank is truly incredible, ive got two now, silver and black, running on an x cube 2, this thing chucks huge clouds on the quad coil on about 60 watts, 90/10 liquid on about 115 watts is pretty much RDA dripping terrirtory its ridiculous, it drinks juice but its well worth it

    - 30/11/2015
    Simply best tank I've ever bought, beats Arctic and Atlantis V1 by a long shot, definitely recommend, massive clouds, and a great 5ml capacity, and refilling from top is an excellent add on too, good buy and recommend to any experienced vapor out there
  • Review by mike
    - 30/11/2015
    Read the hype and watched the video's. Does exactly what it's meant to. Great taste. Plumes of thick vapour. Plenty of airflow adjustment to suit any need. The top fill works well, I've had no leaks.
    The kit is very comprehensive although I've not tried the RBA yet as that's not my thing.
    The coils are immense and need plenty of time to soak. Coil life is very good. No flavour degrade after 2 weeks although it's not my all day vaper. If you take a few hits in quick succession you may get a dry hit. I let it sit 30 secs between hits. 80/20 vg is great. I adjust the wattage between 90 to 110 to suit the juice. I found in extreme cold it may spit but more power sorts that. This is where the top vents work well as you can get a hot vape over 100 odd watts.
    I use the supplied vape bands to secure the swing top (although it clicks in nicely anyway ) and a lower band sat just below the coil wick holes. Essential as this thing guzzles juice and I don't let it drop below the wick holes as I've had dry hits if it does. This does mean I always have a few ml of unusable juice. May be an issue if you want to change flavour but the coil holds so much juice it takes a while to clear through. I just add another flavour on top and mix it through!
    Bit like an old jaguar car. Loads of presence, guzzles fuel and chucks out smoke but immensely satisfying to drive. Build quality is not Rolls Royce but certainly pleasingly chunky.
    Love it.

    This is my first sub tank and its a beast,just be wary that it drinks juice im using 5-7 mls of juice a day.Works best with tri coils

    - 16/10/2015
    so far before ordering this i had the aspire triton tank and the zephyrus tank, all i can say is wow this tank is absolute amzing the clouds are as thick as an RDA and the flaovur is alot more well flavour lol. i havnt suffered any leaky tank yet where with my previouse ones i have and thats was on my 2nd fill with this one i had about 4 fills and no leaks touch wood.

    the triplle coil quad coil makes a real difference.
  • Review by Jak
    - 12/10/2015
    I've been looking for a tank that works as well as an RDA for a good while now.
    This is the tank.
    Faultless vape, mega smooth even at 100watts and up, and doesn't get too hot thanks to the dual airflow.

    I'd fully recommend it with both the triple or the quad coil.
