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?

    Pretty sure this won't be the last of it, Sigelei is moving for more power and many vape fans love it. A must have for vape enthusiasts.

    - 31/03/2015
    Excellent mod, Really easy to use and built really well.
    I scrapped my Smok 50 as it wasn't consistent with ohm readings and tank connection.
    This thing is just flawless, Wack on a tank and you can screw it on flush without the worry over over tightening due to the copper spring loaded pin.
    It basically chucks out the wattage you need instantly with no hesitation.
    Don't think you can get a better box for this price.

  • Review by Paul
    - 21/02/2015
    This is my everyday mod now. Quality of materials, feel of buttons are the best I've used. I have the IPV 3 150w and it is good, quality materials but it doesn't feel as pleasurable to use as the Segelei. Push the fire button and instant response, IPV 3 has a small delay, not more than .25 of a second but it is noticeable and tiresome. Bought the IPV 3 and Segelei at the same time wanting to vape different juice without swapping over tanks.
    Segelei is the way to go, sub ohming on Kanger tank upto 30w is perfect and rba with the Kanger upto 50w. A 150w box mod is extreme, I don't at this time need this much power, but I will one day, Rubber case is great for grip and protection.

    - 16/02/2015
    This is my first box mod, and my first step into the world of sub-ohms (changing up from a Sigelei ZMAX), and I don't think I could be happier.

    I've had it about a week and I've enjoyed every second of it. Really nice, strong vapes, fits nicely in my hand, and it looks fantastic.

    I can't recommend this enough.
  • Review by David
    - 08/01/2015
    Excellent update from Sigelei in this 150W version.

    I have the original 100W, and the 150W has several important upgrades worth the extra price, the build quality feels much better, and it looks much higher quality with rounded edges and polished lines.

    Spring loaded 510 - this is the icing on the cake, the old Sigelei adjustable 510 wasn't great, many people had problems with ohm jumping, all that is gone now, everything fits great, Subtank, Atlantis, Kayfun etc.

    Silicon sleeve that comes with it is a nice bonus, makes it pretty comfy to hold and will protect it from marks and scuffs.

    All in all, nearly perfect, it may of took Sigelei a few versions and revisions, but they are onto a winner with this one.

    Good service from UKECIGSTORE.

    This hits like a train right in the face.
    Works really well at more sensible wattages.

    Looks nice for a bulky box mod.
    Especially with the cover.

    A lot of kit for your money.
  • Review by Brad
    - 03/01/2015
    As mentioned above the picture really doesn't do this mod justice the finish is brilliant, it feels well made and pretty solid considering the weight (it's no itaste vtr). I moved from a Smok Bec pro to this last week and this hits hard, amazing on both subtank and atlantis tanks the subtank looks huge on it with the 22mm adapter but without the adapter (and the skin on the mod) it looks snug and doesn't overlap without it. Been using it daily for a week now and it hasn't failed once. The batteries will only be on about 50% at the end of a day if using around the 25-35 watt range however I did kill them in a full day cranking it up to 70 watts when I was using my dripper for hours. All in all a brilliant mod, great price, awesome performance and it does everything you could ask, you also know it has the power to keep up with anything which is next on the list tank wise as nothing can even handle the power of this mod.... Yet.

    Smashing bit of kit.. looks stunning.. The photo on here does it no justice.. this box mod hits hard! The guys in the store were really help full!
