Questions like the ones above are things that users often wonder about before making an E-cig purchase. Click on one of the questions to be given a straight forward answer.

Just how do E-cigs work?    Answer Below

All Electronic Cigarettes work on a simple principle. There is a power source , usually a battery, that powers a heater coil (atomiser). This atomiser turns fluid into vapour (steam) which is breathed in by the E cig user. The fluid or E liquid contains chemical nicotine and other ingredients such as flavourings to simulate the smoke produced by a conventional cigarette. E-cigs come in many forms to suit an individuals requirements.          Back To Top

Which E-cig is right for me?    Answer Below

There are many Electronic Cigarettes currently on the market that are often sold with all manner of extraordinary claims. This often leaves people considering making their first purchase very confused.

As a simple but effective guide to what an E cig is good for consider its size : Small cigarette like tubes are best used lightly as social smokers. The larger the E cig and its battery size, the better it will be for all day use.

Ask yourself one simple question : How much use will you give your E cig and make your purchase accordingly.

Small E cig = light social smoking use / Large E cig = all day heavy use.

Other key factors to consider are its type of switch , Automatic or Manual and the type of atomiser the E cig uses.

Automatic switches operate when the user draws on the E cig, this makes them ideal for new users. Manual switches need to be pressed by the user. They offer greater control, but might be a little difficult for new users.

Cartomisers are ideal for new users, but more advanced E smokers may well opt for a different atomiser choice.          Back To Top

What atomisers should I use?   Answer Below

There are many atomisers currently on the market. Here we will give a brief description of the atomisers that we use in our range of products. Remember that all atomisers wear out with use and need to be replaced to maintain a good E cig experience.

The 510 Cartomiser: This is a disposable atomiser that is ideal for the new user. Convenient and reliable, simply recycle the cartomiser when it has run out of fluid. Each cartomiser contains enough fluid for 200 to 300 draws. Some advanced users refill their cartomisers to reduce running costs.

The Mini 901 Atomiser: This atomiser is a cost effective choice that is widely sold. It uses replaceable cartridges to contain its fluid. Most advanced users top up or refill their own cartridges with fluid to lower running costs. It has a reasonably long life, heavy users can expect 7-10 days use from this atomiser before its performance drops off too much. Lighter users may go several weeks before they need to replace this atomiser with a new one.

The 510 Atomiser: The 510 atomiser is very similar to the Mini 901. It uses replaceable cartridges to contain its fluid. Most advanced users top up or refill their own cartridges with fluid to lower running costs. It has a reasonably long life, heavy users can expect 6-9 days use from this atomiser before its performance drops off too much. Lighter users may go several weeks before they need to replace this atomiser with a new one.

The Classic Be112 Atomiser: This atomiser is larger in size than the 901 or 510, and its cartridges hold more fluid. They produce a nice flavoursome amount of vapour and should last as long or longer than a 901 before they need to be replaced. Most users refill their cartridges to reduce running costs.

The Classic Be112 Tank Atomiser: This variation of the classic Be112 uses tank cartridges that hold neat fluid which is delivered to the heater coil at a consistent rate. Users can replace or refill their cartridges. They produce good amounts of vapour and offer the convenience of the tank cartridge system. We are currently testing these atomisers as they are new to the market.

The SD-Ego Tank Atomiser: This Atomiser uses tank cartridges that hold neat fluid that is fed to the heater coil at a consistent rate. They produce good amounts of vapour and are very convenient to use. Users can replace or refill their carts. These atomisers are new to the market and were currently putting them through their paces.          Back To Top

How long do atomisers last?   Answer Below

All atomisers lose performance over time. Slowly but surely the heater coil and wick materials in the atomiser degrade which results in less vapour being produced. As a rough guide a heavy user swapping from 40 cigarettes a day to full time E-smoking can expect to replace the atomiser every 7 days (for optimum performance). A lighter user may get several weeks use from an atomiser before it needs replacing. If your batteries and cartridges are in good order but your E-cig isnt producing as much vapour, then its usually time to replace the atomiser.           Back To Top

Whats in the fluid and carts?   Answer Below

The E-liquid found in bottles or cartridges has a blend of chemical nicotine, flavourings and other ingredients such as propylene glycol to simulate the smoke produced by a conventional cigarette. It comes in many flavours and strengths to suit a users needs. The strength of the nicotine content is measured in milligrammes per milliliter of fluid. A typical higher strength fluid will contain 16 to 24 mg per ml nicotine content.           Back To Top

What strength of fluid is right for me?   Answer Below

A typical user should be quite happy with a fluid strength of 16 to 24 mg. We would not recommend super high strength fluids above 30 mg. Many E smokers slowly reduce the strength of their fluid (E-liquid) over time to reduce their nicotine dependency. Eventually using this method an E smoker can kick the habit completely.           Back To Top

Just how much do E-cigs cost to use (supplies etc)?   Answer Below

The running costs of any electronic cigarette will vary greatly depending on the amount of use (and the type of device) that it is given. Here we will give 2 examples, one light user, and one all day heavy user.

Example one: The light "social smoker"

The light user may well use an ecig such as the SD Social Smoker. These are very affordable to buy. If the individual uses his/her device for 1 hour per day then they will need 1 new cartomiser every 2 to 3 days. If purchased in bulk the cartomisers are approx 1 each. So this light social smoker who uses their device for 1 hour per day can expect to spend about 3 per week on supplies. Light use E-cigs do not contain the same heavy weight batteries found in all day devices. This means they may need replacing sooner.

Example two: The all day heavy user

The all day heavy user swapping from a 30 cigarette per day habit will be using an ecig such as our SD-Ego. Most heavy users purchase fluid and refill their own cartridges to keep running costs down. A typical ex 30 per day individual will use 2 to 3 ml of 24mg fluid per day. To maintain optimum performance we would recommend a heavy user replace their atomiser once per week. Over a 1 week period this equates with 17.5ml of fluid at (approx) 9, and 1 atomiser at roughly 6. So far the total per week for a typical ex 30 per day E smoker is about 15 per week. We would also recommend that 1 new cartridge be used per 2 days even if the user is refilling them so as to maintain optimum performance. So the total per week for this example user would be approximately 17 per week. This would compare with a 30 per day cigarette smoker spending 63 per week (at 6 per pack of 20)!          Back To Top

My Ecig used to work great, but its "wimped off", why is this?   Answer Below

The 3 most common causes of your e cigs performance dropping off are as follows:

1: The atomiser is old and needs replacing.

2: The cartridge is old / dry etc / and needs replacing.

3: The battery is old and needs replacing.

Also make sure to clean the electrical connections and parts of your e cig on a regular basis. They can get messed up with fluid and such meaning your e cig will not operate properly.          Back To Top

How much fluid should I use?   Answer Below

Below are some typical examples of how much fluid (E liquid) an E smoker uses:

A light social smoker should use 1ml (or 1 cartomiser) of 24mg strength fluid or less per day.

An ex 30 cigarettes per day person swapping completely to E smoking can expect to use between 2 and 3 ml of 24mg fluid per day.

These figures can vary greatly depending on the users actual E smoking habits. But we would not recommend that any E smoker uses more than 5 ml of 24 mg per ml fluid per day.          Back To Top

How long will my batteries last?   Answer Below

The run time of your E cig will vary greatly depending on the type of device, and the amount of use it is given. Below are some examples of typical run times:

The SD Social Smoker will provide 100 to 150 draws before it needs recharging. This may happen over 1 hour, or used sparingly it may last a user all day.

The SD-Ego, Mk1 and Mk2 SD's all use much larger batteries. This means a user may get several hundred draws before the battery needs recharging. Typically a heavy user will go several hours or longer before the battery in these devices needs recharging.

Bear in mind that if a high power (lower resistance) atomiser is attached to your E cig that run times between charges will be lower.          Back To Top

If atomisers are consumable parts that wear out, then why do some sellers offer lengthy guarantees?   Answer Below

Atomisers wear out.

This is a fact no matter what guarantees or claims sellers make. Many sellers make extraordinary claims about their products. We dont. Instead we use our years of expert knowledge and research to give honest and reliable information.          Back To Top

How many times can I recharge my batteries?   Answer Below

All batteries degrade over time. Each time you recharge your battery its run time will get a little less. Ever wondered why your laptop used to run for 4 hours on batteries but only manages 1 hour of use now? Its the same with any battery but how does this affect your E cig?

The battery in a small device such as the SD Social Smoker is being worked hard. It is a tiny thing thats powering a similar atomiser that a product like the all day SD-Ego uses. It will manage about 30 charge - discharge cycles before a user may notice a significant drop off in run time. If charged once per day this means a user may wish to replace the device after about 1 month.

An ecig such as the SD-Ego, Mk1 / Mk2 ScrewDriver contains a much bigger battery. Its not being worked as hard as the Social Smokers battery, and so it will manage many more charge - discharge cycles before it needs to be replaced. These devices normally manage 200+ charge - discharge cycles before a user may wish to replace the battery / kit.          Back To Top

How do the atomisers work?   Answer Below

All atomisers work using a simple principle. The atomiser contains a heater coil, this heater coil gets hot enough to turn small amounts of liquid into vapour (steam). With use the heater coil and other wick materials in the atomiser degrade. This causes a decrease in vapour production and indicates that it is time for a user to replace their atomiser.          Back To Top

Can an electronic cigarette be used to quit smoking?   Answer Below

At present there have been no clinical trials commissioned and completed to suggest that electronic cigarettes can be used to quit smoking. As such they can not be sold as smoking cessation or nicotine replacement therapies.

However many of the hundreds of thousands of E cig users world wide claim to have had great success in cutting back or stopping completely the smoking of conventional tobacco products.          Back To Top
