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 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.

    My first box and i chose well. Ive had it for over a week and only had to charge it once.

    Can use while charging which is great because i just plug it into my PC, so its right there by me.

    I paired it with the Kanger Nano, seems like the box has way more power than it needs. Still getting used to it but enjoying it at 17.5W for now.

    Highly Recommend.

    The Istick is extremely popular and is pretty much a benchmark for box mods. The 50w powers most drippers and tanks!

    I've had an innokin itaste mvp 3 for a fewmoths now and loved it but needed something with a bit more power. For the price this thing is a BEAST. It's also tiny in comparison to the mvp so it blows my mind. Obviously the battery life isn't quite as lengthy but for the extra 20w of power the istick gives you I think it's a fair trade off.

    Very high quality across the board :)
  • Review by Ed

    Arrived a few hours ago. Done much research on the box mod to get and after checking them all out, this came out trumps.

    Previously I was using a lowly iBreathe stick with a cheap charlie tank.

    Bloody hell. Plugged this into a nautlius mini, and almost died! The difference is night and day. It's bloody amazing!

    My sis, a heavy vaper is even impressed! This thing and even a cheapo tank at anything above 15w will show you what you've been missing!

    No more huffing to get my fixes!

    I love mine but getting really upset with it, this is the third time it just does not fire up, the window is blank, the battery was charged, having a harder time today trying to get it to work. Read that others on the net out there are having the same problem with this thing. I may be out of warranty and even if it was I have a real hard time to get out to return it so I am really bummed......

    The eLeaf is strong and provides good quality for it’s money, bought it on sale and never regret it. The 50w supplies me with capacity to use my dripper
  • Review by Ash
    - 15/04/2015
    I have been using this mod for just over a week now and its been performing great.

    It feels great in your hand and looks the part. Sadly its get fairly scratched and battered yet it may just be my lack of care yet I would HIGHLY recommend purchasing a Silicone Sleeve or getting some vinyl wrap for around it.

    The screen is easy to see in bright conditions and displays all the necessary information.

    The battery life is superb I have never managed to flatten the battery in a days use! The battery happily lasts me a day and a half at around 30-45W.

    The 510 thread seems to be causing me some issues as I usually struggle to get my SUBTANK off the device and resort to using some pliers yet again this may just be me.

    One concern about this product is its authenticity. The box contained no scratch code which all that I've seen do. Using common logic though I believe this is because mine was part of the very first batch of them sold.

    This is amazing VW / VV Mod which is suitable for any user whether they are just upgrading from a basic device or more advanced users.
    - Simple!
    - Stunning Battery Life
    - Fantastic Aesthetics
    - It can be easily scratched and damaged

    - 13/04/2015
    Amazing build quality, unfortunately I got the pink one although I now have a carbon fiber wrap on it so it doesn't look too bad at all.

    The battery lasts around 4 days (even with me vaping at .5ohm for hours a day). Perfect match for my subtank mini as it's pretty much flush. Literally the only downside to this device is that it takes so long to charge (5 hours with a 1A wall adapter), but that ties in with just how large the battery capacity is.

    Had my istick for 3 days and I love it, great price using it with my aspire nautilus mini and aspire Atlantis
  • Review by David
    - 08/04/2015
    I bought this to go with my sub ohm builds and find it to be perfect for these and also higher resistance atomisers. Lightweight, great battery life between charges. 5 hour charging time is the only drawback I have found. Just switch to another mod no big hassle.
  • Review by Stephen
    - 07/04/2015
    This is the most ergonomic thing in the universe, I am sure of it!
    Wonderful build quality, unbelievable battery life and sexy aesthetics to boot!
    Best Mod money can buy if you don't want a higher wattage!
  • Review by RED 5 NICK
    - 07/04/2015
    Great price and great mod. For a 50watt variable wattage and volttage mod this is great for the money. Love the ability to use whilst on charge, nice and compact fits perfectly in the palm of your hand. Simple to use and easy to vape with. The only criticism I have is the US version come with USB plug in wall adaptor as well as the USB cable which the UK doesn't. So for that reason I will give 4 stars the UK version in my mind should have same accessories.

    - 06/04/2015
    i recived this product and everything seemed great until i realised there was no serial code to check if it is authentic aswell as the top part of my screen pops out of place so im left to wonder, is it real or is it a very well made clone. Honestly i thought i was grabbing myself a good deal seems as they seem to go for around £55 but no i wish i had paid the £55 for it

    I'm happy with the iStick 50 so far, seems awesome. No authenticity sticker on the box though?
  • Review by Emma
    - 02/04/2015
    This is very impressive, the build quality is as you would expect from eleaf, very sturdy and it feels really nice. The colours are all really nice but I opted for a silver one just to be a bit different as most of my other mods are black.
    The battery on this lasts easily for 4 days with a full charge and it doesn't get hot to the touch which is very nice.
    It's easy to use, looks great with a nautilus mini on it and it lasts for ages, well done guys it's awesome.

    I have just recieved this...30 mins ago...and first impressions are very good. Feels nice and compact in the hand and pocket...could see P3 going back in its box... it will be on ?bay shortly as I am 'old' soon and getting vaporflask for birthday ;-)

    - 21/02/2015
    Didn't buy the battery off this site, bought it elsewhere but thought I'd add my thoughts.
    Absolutely amazing box mod! Had it for 4 days now and can't find one flaw in it! The battery life is incredible (so it should be with 4400mah). Also the spring loaded 510 connector is great as it allows your atomiser/RDA to fit perfectly on to the device. Also it allows you to lock the wattage on the device so you don't accidentally change it when its sat in your pocket. I've been using my customised Dark Horse RDA with a 0.2ohm parallel coil and at 45watts it chucks clouds like a mechanical mod!
    I also use my Atlantis and my Subtank Nano tanks on it just as my every day vape and its amazing.
    The size of it is perfect and the positioning of the firing button works really well in your hand.
    Can't think of anything that's wrong with it, other than the screen on it feels a bit loose.
    Overall am amazing mod, a definite buy if you're looking for a box mod!
