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

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?

  • Review by Alex
    - 08/11/2016
    If you only ever vape in wattage mode and aren't too bothered about going over 100w then this box mod is perfect it runs like a dream no lag, no misfire just pure flavour and vapour I have 2 one firing a client and the other a tfv8 cloud beast and both are perfect for it. Battery life is excellent too! With two decent 18650s like LG or Samsung the battery will last me all day at around 70w. If you don't need the fancy stuff like TC then this is a serious contender to look at! Some people may see a downside being the fact that there's no usb charge port however the negative effect these have on batteries isn't really worth it. The only negative point I see with this mod is the case its pretty prone to scratching and chipping however sigelei do provide a silicone case in the box so its not really that much of a problem however they must know that the case has problems otherwise why provide a cover for it? On the whole a solid 4/5 from me.
    Alex out.
    Peace. Love and Vapour!

    One of the bigist but not the fatist by far the best esig I've ever had a lot better. Then the cool fire and packs a punch and half and cheap put a nice silicon. Case on it and by far the best in the world

    I've had this box for 3 months now and I can say with confidence that it is easily my favourite of all the ones I've used.

    It's a real no nonsense box. You pair this up with a good sub-ohm tank and some 0.1-0.2 ohm coils and you're onto a cloud spouting winner.

    I take this with me to work every day and to clubs at weekends. It just doesn't care. Performs at it's best, all the time. All it needs is for you to charges the batteries and hit the fire button.

    Got this in the boxing day sales for £20 and it's my first MOD that fires over 50w and I love it my only negative is that it came with scratches all over the screen but other than that it's great.

    Got one of these from my local vaping outlet, I needed a new device as I dropped and broke my K-BOX -sobs-. I'm amazed with the build quality of this device for the money, it's really top notch gear! Plus they include a free silicone case! The magnetic door holds on great, the clicky buttons are all really good quality! I highly recommend this product!

    I love it! Other than my mech, it's the only mod I've found that will fire my coil builds. Awesome mod at a reasonable price.

    - 13/01/2015
    An absolutely excellent device. Built like a tank. They've taken all the comments about the 100W and improved on all the niggles.

    A perfect partner to an Aspire Atlantis or Kanger Subtank.

  • Review by Stephen
    - 15/12/2014
    I purchased this mod mostly because it can hold 2 18650 batteries, it is my first box mod so i cant really draw any direct comparison to any other box mods.

    Having said that I am pleased with the Sigelei, the magnets for the back door work very well. The inside is very tidy and neat with a ribbon to easily remove the batteries. There are no wires etc on show. The exterior is quite plain and understated without excessive branding / logos etc which I really like. The corners are not exactly sharp but its much more comfortable in hand with the optional silicone sleeve to protect the mod.

    The power levels this thing can provide are immense! I don't think I'll ever need 100w and I am happy with 25-30w, as mentioned earlier I got this one because it can hold 2 batteries.

    The buttons work well and are quite 'clicky'. One small annoyance is when you are using less than 50w you can only increase your wattage in 0.1 increments and holding the button the wattage increases very quickly so it can take a few moments to accurately acheive your chosen wattage. After 50w the watts increase in 1w increments and its much easier to find your chosen value.

    I like the fact there is no sub menus to go through, everything you need is all on one screen. Battery life, ohms, watts, volts. Everything is there in on an easy to read and clear screen.

    Overall i can easily give 5/5 and recommend this mod to anyone looking to purchase a powerful mod and im sure even the most hardcore of cloud chasers would enjoy this product!

    Looks Good, Feels good, and vapes like an absolute monster, would recommend to anyone looking for a high wattage box, one downside is the size, even though it is small for the power output, it is still quite large.
  • Review by Mike2003x
    - 10/11/2014
    This mod is a steal for 60 pounds. 95% efficient and enough power to light up any coil set up your devious mind can think of. I like pretty (and expensive) tube mods but this unit is so efficient I can't put it down.
  • Review by sirvapesalot
    - 07/11/2014
    As it says on the tin. Quite big but to be expected with two 18650. Very good value for the money. Nice resolution screen with all the info there. Only negative so far is the battery fitting is pretty specific. Will not work with button top from what i've seen.

    first of all thank you ukecigstore for upgrading my postage to DHL it arrived very fast. the mod is fantastic but the back cover diddnt sit flush due to a piece of plastic sticking up more than it should but i just sanded it down now it sits perfect. chasing clouds this on mod is fantastic and using it at work with an aspire mini gives me an insane amount of battery life. i love this mod!!!!

    - 17/10/2014
    I think this is perfect. I'm all about the powerful mods and so far this has been may favourite. not only does it have the pwoer necessary for huge clouds but it is very well made. Very happy with my purchase
  • Review by paul watson
    - 17/10/2014
    Phil Busardo has for a long time been going on about wishing mods had stepdown,this mod has it,although he only mentioned this in passing.
    You can put a sub ohm coil on it and it will still step down to 10 watts its min power no other mod so far will do this.
    In his rarther cantankerous review in which he finally had to give a thumbs up to the sigelei I find it amazing that this feature of stepdown which he has been ranting on about for months was given such short thrift.
    Just get the impression he is very biased to stuff made in the states.

    Just received today, well packed, certificate of origin and a pack of spares, with 5x5ml of e-liquid from uk-store (thanks).
    The box mod has a good finish, no scratchs, the inside is clean. Work very well, tried with 3 atties and i can't vape more than 50w, 100w is for fun to make clouds.
    Thank you Ukecigstore.
  • Review by paul watson
    - 09/10/2014
    This is everything I have ever wanted,i paid the same amount for a VTR and this is in a different class.Just wish they had rounded the edges or corners to fit better in the hand even if it cost another tenner.
    Incredible value for money compared to some USA mods and just as good or better.
  • Review by Sublime
    - 09/10/2014
    Ok, so there was a wait. I don't blame Ukecig for this. The device itself? Brilliant and i'm so happy i purchased one. The looks, although basic, work for some reason. Hoping they bring out some skins though.

    5/5 so far.
