FAQs

How does a VON ERL. e-cigarette work?
It's quite easy, really: You charge up the battery, fill in the liquid, switch on the e-cigarette and you can start vaping!
And in a little more detail: VON ERL. e-cigarettes consist of a rechargeable battery, an integrated tank and vaporiser unit and a mouthpiece made from medically approved stainless steel. The VON ERL. liquids are filled into the tank and vaporiser unit. Please consult the manual for instructions on how to fill the e-cigarette. The e-cigarette is switched on and off by pressing the switch on the battery 5 times in short succession (approx. 2 seconds). Heat turns the liquid into vapour. During each drag, the switch has to be pressed for the duration of the inhalation. You can simply pull off the mouthpiece from the tank vaporiser unit and clean it with warm water from time to time.
What materials is my VON ERL. e-cigarette made from; is there a risk of an allergic reaction?
VON ERL. only processes high-quality raw materials in its VON ERL. e-cigarettes. Particular attention is paid to the mouthpiece, which is made from medical stainless steel. With this material there no danger of developing allergies.
What substances are produced when the VON ERL. liquids evaporate? How does this compare with the classic tobacco cigarette?
When using a VON ERL. e-cigarette the liquid vaporises at approx. 260°C. This creates aerosol (vapour), which we vapers love so much – in addition to water vapour it also contains by-products from the ingredients of the liquid.
Studies measure the risk potential of these aerosols using the HPHC value (harmful and potentially harmful constituents). The aerosols emitted by e-cigarettes do up to 1,500 times better than the smoke of conventional tobacco cigarettes. They contain around as much HPHCs as normal ambient air. Since unlike tobacco cigarettes e-cigarettes do not involve combustion, the health risks are also reduced. (see: "Comparison of select analytes in aerosol from e-cigarettes with smoke from conventional cigarettes and with ambient air", Rana Tayyarah, Gerald A. Long, published in Regulatory Toxicology and Pharmacology, Issue 70 Volume 3, 2014).
What are the ingredients of the VON ERL. liquids?
The VON ERL. liquids contain natural and nature-identical flavourings, propylene glycol (E1520), vegetable glycerine (E422) and distilled water. VON ERL. liquids are available with or without nicotine – which means that the nicotine content varies between 0 mg and 18 mg. The carrier liquids propylene glycol (ensures that the flavourings and the nicotine are evenly distributed) and glycerine (which produces the vapour) are also used in asthma inhalers and many cosmetic products.
Please note: nicotine is a substance that can cause addiction. Liquids containing nicotine must be kept out of the reach of children under the age of 18. They are also not suitable for use by pregnant women. People suffering from respiratory or cardiovascular diseases should not use liquids that contain nicotine.
How many cigarettes is one tank full equivalent to?
The consumption of VON ERL. liquids mainly depends on how strongly you inhale your e-cigarette. On average, 0.1ml of liquid is equivalent to one cigarette. Model B1 VON ERL. has the equivalent of about 12 cigarettes in the tank, the tank content of the larger model E1 VON ERL. is equivalent to about 16 cigarettes.
What nicotine level is right for me?
VON ERL. liquids are available in nicotine strengths 0mg/ml (without nicotine), 3, 6, 12 and 18mg/ml. We recommend the 6mg/ml strength as the equivalent to light cigarettes, the 12mg/ml strength as the equivalent to strong cigarettes. VON ERL. e-cigarettes containing 18mg/ml liquids provide a lot of nicotine.
How long does the battery last for, and how long does it need to be charged up for?
The batteries of the VON ERL. e-cigarettes are designed to provide enough energy to vaporise at least one tank full. To fully charge the battery takes around 3 hours; however, after about 20 minutes of charging time, the battery will be about 50% charged.
Is there a negative impact on the environment similar to passive smoking?
The aerosol that is breathed out by an e-cigarette user contains almost no nicotine and contains no substances that are harmful to the environment (see above). You are therefore not putting the environment or other people at risk. The scent of the flavourings dissipates quickly, with a half-life of only a few seconds. The half-life of cigarettes, on the other hand, is several hours, which is why cigarette smoke stubbornly clings to clothes, hair and furniture.
Where can I use VON ERL. e-cigarettes?
E-cigarettes do not burn tobacco, which is why they are not a tobacco product. Any smoking bans therefore do not apply to e-cigarettes. However, in all private and public spaces the so-called domiciliary right applies, which means that the use of e-cigarettes can be banned. As a matter of good practice, it's best to consult the people in charge about the use of e-cigarettes. We strongly disapprove of policies aimed at banning the use of e-cigarettes in places where smoking tobacco cigarettes is also prohibited. E-cigarettes pose no risk to the environment and a much lower risk than tobacco cigarettes for the user himself.
What is a rebuildable vaporiser?
With rebuildable vaporiser the vaper so inclined can decide how to assemble the vaporiser unit consisting of wick, wire and airflow himself. This also has to match the liquid that is used. The voltage or power of the battery holder can also be adjusted. Based on these parameters, the vaper can adjust the vaping behaviour of the Erlkönigin. Of course, that's quite complex and calls for plenty of patience and experience.
What is a puffer?
Puffers are short pieces of wick or cotton wool that are added to the feed-in wick of the coil. They increase the volume of the liquid in or around the coil. Pieces of puffer are not in direct contact with the liquid in the tank and are fed by the main wick. Quite often, the main wick of high-performance coils cannot transport enough liquid. The puffer minimises the risk of the burning taste because there is always plenty of liquid to be vaporised. In the Erlkönigin the feed-in wick is specially led, and we call it the "Brückendocht", the bridge wick.
What is a bottom coil vaporiser?
The Erlkönigin is a bottom coil vaporiser. The coil is close to a mains connection. This ensures that there is a short and reliable path for the current feed and no non-resistance wires are required.
The wick is also close to the bottom of the tank. This ensures that the liquid is transported more easily because the paths are short. This in turn ensures a constant flow of liquid to the coil. Because the mouthpiece is positioned at quite a distance from the vaporiser unit, the vapour is not too hot once it reaches the mouthpiece.
What is a wick?
Just like the wick of a candle, it transports the liquid from the tank to the coil, where it is vaporised. This works by capillary action. Wicks are made from all kinds of materials. Silicate, glass fibre, cotton wool, ceramic, stainless steel screens, steel rope. The Erlkönigin only works with silicate, glass fibre or cotton wool wicks.
What type of wick is used is up to the do-it-yourself vaper.
What is a resistance wire?
The coil of the vaporiser is made from resistance wire. Such wires are also used in heating elements, hair-dryers and toasters, among other things.
The wires are made from different materials (kanthal, CrNi..); they are special alloys with a significantly higher internal resistance. The wires also come in different diameters. The smaller the diameter, the higher the resistance for a given length. On the other hand, resistance increases for a given diameter with increasing length.
Expressed in terms of the rebuildables, the resistance of the finished coil can be set in different ways. The diameter of the coil, the number of coils and the thickness of the wire all influence the resistance (ohm), which is measured on the vaporiser.
What type of wire is used is up to the do-it-yourself vaper.
What does negative pressure principle mean?
It's the same principle as an upside down water glass in a basin of water. If you pull it up right to the edge, it stays full up. The ambient pressure is counterbalanced in the glass and the water stays in the glass. If you briefly lift the edge of the glass above the surface of the water, air bubbles form in the glass and the water level in the glass goes down a little. That's exactly how the tank of the Erlkönigin works.
Based on the negative pressure principle, with each puff a bit of liquid is transported from the tank to the vaporiser unit. And vice versa, a little air flows back into the tank and compensates for the difference in pressure.
What principle is the Erlkönigin based on?
The Erlkönigin is a so-called bottom coil vaporiser. The tank works based on the negative pressure principle.
Why is the Erlkönigin so light?
In a nutshell: we wanted to create a compact and light rebuildable vaporiser with a large tank for everyday use. The standard Erlkönigin weighs around 32g and holds between 3ml and 6ml of liquid.
However, despite its expensive lightweight construction, the Erlkönigin is robust. This positions us in the market exactly between the large and heavy rebuildable vaporisers that we are all too familiar with and the mass-produced products from the Far East.
What type of coil do we recommend?
The Erlkönigin is a rebuildable vaporiser. There are many factors that influence vapour performance. Wire coil, wick, liquid, current and voltage all have an influence on the performance of the Erlkönigin. In addition, all vaping enthusiasts have their own preferences. It is therefore difficult to make a general recommendation.
There is one aspect in which the Erlkönigin significantly differs when it comes to coiling: in the Erlkönigin the main transport wick for the liquid is specially led to the coil. As a result, the Erlkönigin can be easily refilled from the top despite the negative pressure tank.
This so-called bridge wick runs from one side of the tank to the supply channel and back to the other side of the tank via the wick duct. The bridge wick must be neither too thick nor too thin. If it is too thick, it will be pinched off and this makes transporting the liquid to the coil more difficult. If it is too thin, then the liquid can simply run past the wick and makes its way directly into the vaporiser chamber and floods the Erlkönigin.
Ideally, the bridge wick completely fills the supply channels while being loose in the duct. Because the wicks usually swell up a little when they are soaked in liquid, the wick can appear too small when dry. Because everyone has their own preferred type of wick, it is difficult to make a clear recommendation.
That's what's exciting about doing it yourself: finding the best possible combination for the Erlkönigin to meet the vaper's own vaping preferences.
Can I also use standard 510 drip tips?
We did think about that, too. Our product range includes an adapter for our Erlkönigin for the universally popular 510 drip tips. This allows you to use your favourite drip tip.
Can I adjust drag resistance?
Yes, the base of the Erlkönigin has an integrated AFC.
You can use it to adjust the drag resistance of the Erlkönigin. To adjust drag resistance, the Erlkönigin has to be unscrewed from the mod. Then the black AFC ring can be adjusted using just your fingernails, you don't need a tool. When you screw in the ring drag resistance increases. When you loosen it, the drag is easier. The ring may be untightened only until it is flush with the base, or else it interferes with the mod. If you like the drag to be completely free, the AFC Ring can be left out entirely.
What are the tanks made from?
The standard tank is made from a special liquid-resistant co-polymer plastic. We advise against using liquids containing diacetyl or triacetin. This can cause clouding in the tank. Any damage that is due to these flavourings is not covered by the guarantee.
We have tested the tank with very aggressive liquids. We nonetheless recommend that you only use liquids that meet the purity requirements of the association of e-cigarette retailers (VdeH). If you do want to vape using such liquids, we recommend that you use the optional stainless steel or glass tanks from the Erlkönigin range.
What materials are used to make the Erlkönigin?
All materials used to make the Erlkönigin have been selected in accordance with the food standard. We only use certified materials to make the Erlkönigin. All standard parts (including screws) are ultrasonically cleaned in accordance with the food standard..
Do I have to clean the vaporiser before using it for the first time?
The Erlkönigin comes shipped cleaned in accordance with food standards.
It is nonetheless possible for a slightly chemical taste to be present before you clean it. This taste is completely harmless. If that won't do, you can rinse the vaporiser with lukewarm water before you use it for the first time.
Are the O-rings food-safe?
Yes. When making the Erlkönigin we use O-rings that are also used by the food industry. The O-rings also undergo testing to ensure that the liquids do not corrode them. As already mentioned, we advise you to only use liquids that conform to the purity law of the association of e-cigarette retailers (VdeH).
The tank leaks from the bottom!
Make sure the O-ring is clean and nothing is stuck between the O-ring and the tank. It is possible for a piece of wick to protrude from the base and get in the way. Simply shorten the wick a little.
Do I have to weld together a coil using non-resistance wire?
You don't need to do that with the Erlkönigin. The connections are so close to the coil that you don't need any non-resistance wire. This makes building the coil easier and the coil can be attached in no time at all.
How do I clean the Erlkönigin after use?
We recommend that you rinse the Erlkönigin with lukewarm water. The liquids that conform to the purity law should be 100% water soluble.
How often do I have to replace the O-rings?
If you use the Erlkönigin every day, we recommend that you replace the O-rings once a month.
There is a burning taste when I use the Erlkönigin. Why might that be?
This can have a number of reasons. The most obvious reason is that the Erlkönigin is empty. But there could be much more complex causes. Usually the coil is too hot and not enough liquid can be transported through the wick. When the coil gets too hot the resistance of the coil may be too low or the voltage/watt of the battery holder is too high.
There may be another reason that only applies to the Erlkönigin: the bridge wick is too thick and is stuck between base and vaporiser chamber. This causes the wick to be choked off and as a result cannot transport enough liquid to the coil.
We recommend that you watch one of the many hundreds of YouTube videos on how to make the perfect coil.
Can the positive terminal be adjusted?
The positive terminal cannot be adjusted. We do have discs that can be inserted to adjust the height of the positive terminal if there are contact problems between the Erlkönigin and you favourite mod.
I broke the 510 threading :(
The 510 threading of the Erlkönigin can be replaced. The positive terminal screw connects it to the base. The groove is quite large. The clever design means that nothing can come loose when screwing and unscrewing parts. This is also handy if you want to give the air channel a thorough clean and remove any residue. This part is available in our online shop.
Can I use the Erlkönigin with a flathead mod?
Yes. The grooves at the bottom of the base are not just there to help with assembly, they also leave a slight gap so that the Erlkönigin can "breathe".
What is an AFC?
AFC stands for "air flow control". You can use it to adjust the drag resistance of the Erlkönigin. A ring is used to change the cross section of the air opening by turning it on or off.
I can hear a whistling noise when I take a drag.
This is normal for the Erlkönigin and with most do-it-yourself vaporisers. As you vape, several litres of air pass through a rather small duct within only a few seconds.
This causes a high flow velocity, which is expressed as a whistling noise. We have reduced this noise to a minimum for the Erlkönigin and the frequency is more pleasant now.
What is a drip tip?
The drip tip is the mouthpiece. It is often abbreviated as "DT". Most of them have a standardised connection. This is called the 510 drip tip.
Drip tips are ten a penny, and they come in different colours, shapes and materials. From a technical point of view it's mostly the length of the drip tips that makes a difference, because the temperature of the vapour can be adjusted as a result of the longer air route.
What does the tank not being load-bearing mean?
The base, the top and the vaporiser chamber form the load-bearing structure of the vaporiser. The tank is nothing more than a thin sleeve, which the O-rings seal on the base and on the top. This makes the tank float-mounted. When assembling the product the tank is not under tension. This protects it from damage. The tank can be removed and cleaned quite easily this way.
What is a "coil"?
It is what the name suggests. In this case it is a heating coil. The skilled do-it-yourself vaper makes his own coil using resistance wires. It looks a little like a spiral spring.
The purity law!
The association of e-cigarette traders has defined a purity law for e-cigarettes: "Admissible ingredients of e-cigarette liquids are propylene glycol, glycerine, water and nicotine in pharmacopoeia quality (USP/EP) as well as food-use approved, water-based flavourings without any known inhalation risks. No other substances, except for these five ingredients, should be contained in the liquids."
What does "flash" mean?
The term "flash" describes the scratchy feeling in the back of the throat during inhalation. It is similar to the sensation you have when you inhale smoke.
What does "leaking" mean?
This describes the situation when liquid escapes from the vaporiser somewhere. We believe we have done everything we can to avoid leakage in the Erlkönigin.
What is a burning taste?
The expression describes the sooty or smoky taste of the vapour that is produced when not enough liquid gets vaporised. We recommend that you watch one of the many hundreds of YouTube videos on how to make the perfect coil.
What is a bridge wick?
In the Erlkönigin the main transport wick (=bridge wick) for the liquid is specially led to the coil. As a result, the Erlkönigin can be easily refilled from the top despite the negative pressure tank.
The bridge wick runs from one side of the tank to the supply channel and back to the other side of the tank via the wick duct. The bridge wick must be neither too thick nor too thin. If it is too thick, it will be pinched off and this makes transporting the liquid to the coil more difficult. If it is too thin, then the liquid can simply run past the wick and makes its way directly into the vaporiser chamber and flood the Erlkönigin.
Ideally, the bridge wick completely fills the supply channels while being loose in the duct. Because the wicks usually swell up a little when they are soaked in liquid, the wick can appear too small when dry. Because everyone has their own preferred type of wick, it is difficult to make a clear recommendation.
That's what's exciting about doing it yourself: finding the best possible combination for the Erlkönigin to meet the vaper's own vaping preferences.
How can I drain a flooded Erlkönigin?
Because the Erlkönigin has negative pressure, you cannot simply blow into it with force. This would create excess pressure in the tank, which would then immediately be flooded again when you stop blowing to relieve the pressure.
With the Erlkönigin this can be avoided by doing the following:
- remove the Erlkönigin from the battery holder - unscrew the AFC ring - open the tank cap - cover the air channel and the tank opening with a handkerchief - blow through it until all the excess liquid is removed from the vaporiser chamber - close the tank - dry the bottom of the base - screw the AFC ring back on, and that's it.
What is "gurgling"?
"Gurgling" is the sound that is produced during vaping and there is too much non-vaporised liquid in the vaporiser chamber. The chamber may also be flooded. This can be the result of a leak in the vaporiser. It is more common for liquid condensation to develop inside the vaporiser, which will block the airflow. This can largely be avoided by letting go of the fire button a little earlier, which empties the vaporiser chamber of residual vapour. This way the vapour cannot condense inside the vaporiser. Strong air pressure fluctuations (e.g.: when you are driving along a mountain pass) can also cause liquid to enter the vaporiser chamber in an uncontrolled way. The chamber can also get flooded if a vaporiser is exposed to temperature fluctuations. For example, if you left it in the car for a while in the winter and then it warms up again at home or in the office.
What is the wick duct?
We have created a wick duct at the base of the Erlkönigin. To the left and to the right of the middle part, where the coil is attached, we have positioned a little U-shaped duct. This ensures that the wick and the coil are perfectly aligned and always in the right position.
