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 do I need to get started?

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.

    The Flask was a really well created product and can be up to par with the Hana Modz, lovely to hold and use.

    Just upgraded to one of these from a tube mod - bought an Atlantis V2 tank to go with it. The performance of it is amazing, lots of flavor, loads of batter power. A bit pricey, but then you get what you pay for.

    I bought this about a few weeks ago and have to say that I absolutely love it. Yes, it's very expensive but you're paying for quality here. I bought the standard silver model so there's no issues with paint quality as noted by another reviewer.

    I'm using the Nautilus BVC temperature sensing 0.2ohm coils on it and have it set to 430F and it's just fabulous, I can really see the temperature sensing facility saving me from burning coils out so quickly.

    Another worthy note is that it's so comfortable to hold in the hand. Note however that the placing of the fire button means it's aimed more at right-handed people (which I am fortunately). That's not to say it would be uncomfortable for lefties, it would just mean that you would be firing it with your thumb rather than your index finger.

    Note also, it is crucial that you get batteries that are known to fit. The Samsungs do as do the LG's I bought but be sure to remove any stickers on them as the battery tubes are so narrow that anything other than the battery along (ie. stickers) will get jammed in there and you really don't want that!

    As the batteries are run in parallel and not series I find battery life to be superb, two days worth of usage is easily doable.

    One fairly minor point is the display. It's lovely and bright and crisp but it's small. As I'm getting older and at the point of needing glasses to read smallprint I find some aspects of the display very difficult to read, particularly the coils ohms rating. Indeed I end up getting the magnifying glass out to check! It's not a biggie and it wouldn't stop me buying it if I were to buy it again but it's something to bear in mind.

    Overall it's a very nice device and it screams quality (as it should at this price!) and I'd highly recommend it.

    Just taken delivery, stunning piece of equipment.
    Thank you sales for informing me that the Samsung INR18650-25R 2500mAh batteries that you have in stock would fit... Yes they do, although I removed the stickers first and they are snug.
    But all if fine and the device works as I had hoped

    - 13/01/2015
    This is my first box mod and it is amazing. This I guess is like discovering religion, you feel that you have to tell the world and its mother all about it. The finish on mine is perfect in every way, it is tactile and I just don't want to put it down. Make sure you have the right batteries for it, if you are reading this then you will probably know which ones. Mine got fully charged in a couple of hours using the included micro - USB lead. I am using mine with the Kanger sub tank and using the included 1.2 ohms coil. I have the natural finish on mine. Right off to some street corner with a sandwich board to do my duty and tell the vaping community how good this is. Buy it try it, you're gonna like it.

    - 06/01/2015
    I love this device, for looks, comfort to hold, has enough power for my vaping needs and great battery life.
    However, build and paint finish is not the best for such an expensive device and every 12 hours or so, I have to pull the batteries to reset the display as it gets garbled when running in Temp mode, I know this is a fault of the DNA chip though, not the Flask.
    Good luck finding compatible batteries, VTC or LG HE2 recommended though I have found Samsung 25R fit well too.

    Overall im happy with it, but the price is silly.

    This is truly in my opinion worth every penny. The temperature control is working flawlessly and will change the way you vape. I wish I could afford two.
  • Review by Simon
    - 02/01/2015
    Lovely device to hold and use, the dna is working perfectly and the duel 18650s seem to last forever, three days when using temp protection easily.

    Pricey but absolutely worth the investment.

    - 31/12/2014
    This arrived yesterday, so after 24 hours use, here are my thoughts.

    The Good:
    Fantastic looking device and fits well in the hand, fire button placement is spot on for me.
    Put in two fresh charged VTC5 and so far still have around 90% battery after several hours vaping between a 1.0ohm lemo and 0.08ohm ni200 dual coil build running at 12-20 watt respectively.

    Tha Bad:
    The black finished coating appears to have spit or water droplet marks, but they wont wipe off so it looks used, my Efest and Samsung 25r batteries will not fit.
    The fire button is very soft and takes little force to press and has no feedback that you have, but works well and fires every time.
    The top plate is not flush and light can be seen through the gap.
    For a £249 device i would have expected a far better finish and presentation. But for the abttery life its hard to get anything else.
    If you want just the battery life and not worried about 40 watts or temp control, get a Sigelei 100 watt or get the VF clone... Far cheaper.
