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 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.

    Nice and solidily built, feels nice in the hand. my only one negative is the battery spring. it drills into any battery as it has a sharp edge to the spring.
  • Review by Jamezb09
    - 09/11/2015
    This is a really good box mod, really simple and does give you a really good idea of how much charge you have left in your battery. I would definitely recommend this, the only thing I would say is the battery screw end can be a little bit annoying taking on and off but it's nothing major to be honest

  • Review by Tyler
    - 09/08/2015
    Works perfect and no problems what so ever, the only downfall for me is the size of the charger I have, not sure if you can get smaller ones but well worth the minor inconvenience
  • Review by DannyWragg
    - 29/06/2015
    This is a well built mod that fits comfortably into my hand and pocket! Uses a single 18650 battery and works great with my subtanks! Only downfall(and its subjective) is not screen to set watts and only certain wattages to choose from!
  • Review by Peter
    - 22/06/2015
    I recentley purchased this along with the subtank plus, made for each other, a good combination. Excellent value for money, I can vape all day without refilling or having a battery die. I am well impressed.
  • Review by Rob
    - 14/06/2015
    After having my KBox and subtank plus now a short while, I can honestly say they are a great combination, and here is the but.....

    The rubber insulator spring loaded centre pin has split on me as mine is keeping shorting out, and I've only had it about 6weeks!!

    Will be in touch tomorrow to see what can be done to sort this out as I am not too impressed with this to say the least, hopefully the guys at shop can get something sorted out, but how many of these mods will develop this issue remains to be seen which is a shame as it is otherwise a great product.
  • Review by J
    - 10/06/2015
    I paired this with my subtank and the flavor is damn fine and the subohm OCC coil (and the RBA) produce beautiful thick clouds. My only complaints so far (one week in) is that: 1) the spring on the battery cap is quite strong making it difficult to put on and it has a tendency to shoot across the room when removing it if you aren’t careful;
  • Review by Boybergs
    - 08/06/2015
    Ive been using my new kbox for a couple of hours now. I agree with the majority of reviewers that, for the money this is an outstanding bit of kit; looks great,feels great and works perfectly. My only minor reservation is that, out of the four tanks I own it only really suits the sub tank mini. My others are not sub ohm tanks and they all seem to taste burnt on any wattage other than the 8w option but the 8watt opion is not quite enough. So an additional increment of say 10wwould make it a definite 5/5. Currently ive only got 1.8 atties so im going to try a 1.2 and see if this helps.

    - 28/05/2015
    Got this to go with my Subtank Mini, running it in RBA mode with VTC5's in this and it delivers amazingly well for the money. If you want a reliable tank/VV solution, get the combo and you'll be totally satisfied. Works great with my Derringer sat on top too, pushes power straight away with minimal ramp-up.
  • Review by Jeremy
    - 28/05/2015
    I just wanted a simple robust, cheap mod to use at work and this fits the bill perfectly. No bells and whistles just does the job well. all you could need, if you break it or loose it its not expensive and you haven't lost a lot of money. I noticed some people complaining about the thread on the battery box. It must just be bad luck because mine is nice and smooth, looks awsome in black as well.

    Does what it says on the tin, using with my Aspire Atlantis and it is perfect. For the price can't go wrong and great speedy service and free delivery from Ecig store.
    Happy days

    - 20/05/2015
    Works really well , power settings cope with everything I've used including subtank plus .
    Would recommend this box mod to anyone
  • Review by James
    - 14/05/2015
    Got this as a out n about mod to go with my Subtank mini. It's perfect for what it is and 40 watts is enough for most tanks. Hell I even attached my Tobeco turbo RDA on at 40 watts and it was ok. Some people have moaned about the set watt settings but hey, why did buy it then? This mod is priced right and aimed at the atomizer market not the rebuild market. This does exactly what it says on the tin. Looks great, feels solid, stealthy size with nice large clickey fire pin. You can't go wrong weather it's your first mod and new to vapeing or your an advanced user and are looking for a reliable, smaller back up mod etc. U.K Ecig store on the ball as usual and leading the way.

    - 29/04/2015
    great box mod. looks good feels good and has enough power. small enough to put in your pocket. not like the V5 i had :)
  • Review by Magic Man
    - 28/04/2015
    If your newly I to vaping and looking for an inexpensive box mod then this is a worthy choice without having to shell out a fortune.

    Admittedly it is a tad basic; power button and wattage button allowing you to choose from 7 presets; for a newbie to Box mods you can't go wrong with this one.

    The only negatives are that it doesn't allow for direct charging, but as it takes a standard 18650 battery it is easy to have one on charge and a second in the unit.

    All in all this is a great little unit.

    An excellent stylish box mod designed to work and look seamless with the Subtank plus. Beautifully constructed and amazing value.
  • Review by James
    - 24/04/2015
    This is my first replaceable cell box mod, and all I can say is wow!

    It doesn't half kick out the vapour out with the Subtank Plus!

    It's extremely well made and feel very sturdy, the only con I can see on this mod is the battery cap threads are a little rough and it can be hard to screw it back in place.

    Just make sure you use at least a 20Amp battery else the device won't fire or worse it could cause the battery to vent.

    I purchased the Vaping Outlaws VOX2 with two VO Vape Cells when I brought this, they work great and are rated at 22Amps.

    You can't get better for £25!

    - 08/04/2015
    I do not find the wattage setting an issue when using it with the Kanger Subtank with stock coils for which it is designed. Works perfectly and very easy to use. Battery usage is more controlled than many other mods it will cut out at 3.5 volts whereas most of my other mods cut off at 3 volts. Hence more regular charging and likely longer battery life. If you build your own coils then the Istick 50 would be a better option for a little more and no battery to buy.
  • Review by Emma
    - 02/04/2015
    My only issue with this is having to use pre set wattages, it's not an issue for most people but I like to have the choice of wattage. also an lcd screen would have been nice but thats not major.
    Other than that it's a great bit of kit, I use this when I'm at the pub or generally out and about as it's a nice size and it doesnt weigh too much.

    I ordered both the k box and the kangertech sub tank mini from this site fast delivery and all I can say is its great for the price I have no complaints and I would recommend I've had an mvp v2 and I also own a VTR and this is just as good :)

  • Review by Shrek
    - 13/03/2015
    I'm in shock with it. It's about the same size as a MVP 2.0 but not as boxy, it weighs a touch more than the MVP (With a Sony VTC5 battery).
    The threading on the battery base is a little rough,but the price I paid for it,these minor niggles are nothing. It could do with a micro USB on the side to charge it but it's easyish to change the batteries. Well worth what I paid for it. I mainly use a Cloupor t5 50w during the day,when I have access to a power supply to charge it.
    This is great when going to the pub,as you can just change the battery. The cloupor require 3 miniscule screws,not good after a few sherbets.

    Ordered the Kbox 2.30 yesterday and it came today 11.20, well done guys, never had a problem with deliveries in th two years I've dealt with them, ive got the vicious ant phenom which is great, but it's been burning out my coil on the prebuilt atomiser for the kanger sub tank, it's fine with the rebuildable section though' so I thought ide get the kbox so I could adjust the wattage and it's great, set it at 20 watts and no problems but what a Vape, I love it, kangers at the top in my book, since the sub tank I've never used my Cryptex RDA, can't wait to see what kanger comes up with next, for the price there stuff is amazing, cheers kanger and thanx ukcig store for another fast delivery.
  • Review by carl
    - 05/03/2015
    works really well , lighter than alot of more expensive ones I have and works better.
    only 3 negatives dont expect the silver finish to last long though could be wrong .
    in the product descripion shows a 18650 with nipple, now I use a flat top and dont think theres room for the other .
    The preset wattage of 8 , 13, 20 , 25, 30 , 35 , and 40 .
    only using the 8 and 13 so would have preferred more settings in the under 20 wattage range .

    very good value for the money works very well.
    would reccomend to all .

    First variable voltage device with this sort of power capabilities I have ever used and I'm blown away by it and for the price of it, hands down 5/5.
  • Review by R Sneddon
    - 26/02/2015
    Excellent mod . only bad thing i can say is it does not have the ability to charge the battery so when buying you need a charger and better to also get a spare battery . overall you will not be dissapointed .Excellent little device

    - 19/02/2015
    This is superb. Ignore what people say on forums, fits in the hand great, vape is amazing. Obviously it's designed for the subtank and the 25mm is the perfect fit. No fuss with an lcd screen, 8 - 40W in set increments and a battery indicator - for that price GET ONE
  • Review by Nik
    - 19/02/2015
    Received mine today. Great mod. Works superbly. Looks fantastic. Only thing I will say is Kanger definitely need to up they're quality control. Mine was covered in something sticky and it's covered in scratches and marks. Something I don't expect on a brand new product . Overall though it's a great mod.

    - 18/02/2015
    I bought the Kangertech Subtank to find my way into the world of sub-ohm vaping. I was running the tank on the Innokin iTaste 134 MX-Z. And it was great. Once the K-Box was released I bought it to up my wattage. It is awesome. The e-liquid is warm and flavoursome. Cannot recommend this really lightweight and compact box mod highly enough. Fits great in the hand.

    - 17/02/2015
    My first box mod and well worth it. The amount of vaper, the purness of the flavour and speed of the ignition make this a logical next step in the vaping journey. Great price, lets hope it lasts longer than mym Ipow battery though.

    - 16/02/2015
    Have to admit that I am I big fan of Kangertech products but that doesn't take away from the fact that this is a great mod. The quailty is spot on and the threads are buttery smooth. Fits perfectly with my Kanger Subtank 25mm. Glad I waited for this rather than getting the Cloupor Mini.
