Starters often don’t understand what vaping Mouth-to-Lung (MTL) and Direct-Lung (DL) are, what is the difference between them? In fact, these are the two most common inhalation methods for vaping, and different inhalation methods will bring vapers a different experience. The Direct-Lung (DL) is very similar to our daily smoking techniques when using traditional cigarettes, while Mouth-to-Lung (MTL) is closer to the way of inhaling when using hooka shisha. For more detailed distinctions and details, here we go.

Direct-Lung (DL)

The DL inhalation is the same as our daily smoking method. The user first inhales smoke from the atomizer and then inhales additional air to bring the smoke into the lungs. Compared with the MTL inhalation, the smoke will be in the user’s mouth for a long time, so those accustomed to MTL tend to enjoy the more detailed and subtle flavor of the vape juice.

Those MTL vapers would switch to vaporizers with high coils resistance whose output power is generally controlled below 15W. In order to match these devices, vapers are accustomed to choosing from PG, E-liquid with higher nicotine content to enjoy an inhalation experience similar to the throat hit of cigarettes.

1. Advantages of Direct-Lung

Due to the slow inhalation and the relatively slow evaporation rate of the e-liquid, the same amount of e-liquid can be used for a longer time.

The device does not need excessive output power during direct-lung vaping, which prevents the device from overheating during use.

Because it is used in the same way as cigarettes, the way of inhalation is more popular among those substitute cigarettes.

Direct-Lung is conductive to the smoke staying in the vaper's mouth for a longer period of time, which helps the vaper to obtain a more delicate taste experience of the e-liquid.

Second, the disadvantages of DL

Due to the low output power of the device during oral inhalation and the smaller amount of smoke, the throat hit produced by the smoke on the user is also weaker than that of MTL.

At present, dripping atomizers and high-power atomizers have gradually occupied the mainstream of the market, and DL is outdated.


As the name suggests, the Mouth-to-Lung is that the vaper inhales smoke directly from the atomizer into the lungs, just like daily deep breathing. The dense smoke fills the lungs instantly, similar to the experience of using hookah shisha.

MTL gives vapers a stronger impact experience since big smoke contributes to a richer and fuller taste experience. At the same time, due to the instantaneous evaporation of a large amount of e-liquid, the cooling design of the atomizer has also become very important. Because of the big cloud, the throat hit will be more obvious when inhaling the lungs. Those accustomed to Direct-Lung tend to choose from e-liquid with lower nicotine content.

As mentioned above, most MTL vapers choose from dripping atomizers or Sub-ohm atomizers. At the same time, when it comes to the choice of e-liquid, they are more inclined to choose VG E-liquid with higher content and lower nicotine content to reduce the impact of the throat hit.

1. Advantages of Mouth-to-Lung
Smoke is directly inhaled into the lungs, which contributes to a stronger throat hit while getting a fuller and richer vaping experience. Direct-Lung is the best way for those enjoying big smoke.

Second, the disadvantages of Mouth-to-Lung
Pay more attention when choosing e-liquid. Excessive PG and nicotine content would give you an unbearable throat hit. At the same time, dry cotton burning caused by poor oil conduction will make things worse.

All in all, how long you vape, what devices, atomizers, and output power you use determine whether Mouth-to-Lung (MTL) or Direct-Lung (DL) inhalation is your choice; generally speaking, those beginners are inclined to choose from DL, and most the heavy vapers prefer MTL

How to distinguish the authenticity of IQOS 2.4 PLUS

by Martin Smith

Wanna get the IQOS 2.4 PLUS heat not burn device free shipping, please visit https://www.buyecigkits.com/e-cig-kits/heat-not-burn-tobacco-heating-device/iqos-e-cig/original-iqos-2.4-plus-tobacco-heating-system-kit-free-shipping/

The black of IQOS 2.4 PLUS heat not burn tobacco heating device(Abbreviated as IQOS 2.4 plus) is actually called Navy Blue on the official website, which is a deep blue color that is more like black than blue. Let's take a look at the IQOS 2.4 PLUS's pocket charger first, the one on the right in the pic below that is obviously black is the knock-off, and the one on the right that looks dark and blue is original!

Left: Original Right:knock-offsI( The middle part of the knock-offs is obviously black)

The revolving cover of the counterfeit version of the pocket charger has a smaller gap than that of those original, which looks better when closed. I think it's because the first generation did a poor job, and the copycat version made a lot of hard work to improve it.

Meanwhile, as for the color of the LOGO, there are some differences, the copycat version is clearer, and the lighter color is the original one.

Left: Original Right: The counterfeit version 

Next, let’s take a look at the IQOS 2.4 PLUS hoder. The colors of both sides are very close to the colors of their respective pocket charger. Similarly, the knock-off version of the holder is darker in color, and the gray one is the original. The only flaw in the appearance of the knock-off version is that the LED lampshade is too dark. When the LED is off, it appears black, which is more obvious,please check out the pic circled in red.

Left: Original Right: The knock-off version 

The size of the copycat versions of IQOS 2.4 PLUS is almost the same as that of those original IQOS 2.4 PLUS, and the weight of which is a little heavier. The whole device of the copycat version is about 10 grams lighter than that of thee original device. The holder is 2 grams lighter, while the pocket charger is about 8 grams lighter. As for the AC-Adapter transformer, the copycat version is also lighter by about 7 grams, which may be related to plastic materials, battery capacity and materials, and circuit boards.

As far as the performance of the charging parameters is concerned, the knock-offs can be fully charged in an average of more than 2-3 minutes, which is comparable to the improved speed of IQOS 3. However, the charging time of those knock-offs version varies greatly each time, it takes more than a minute to be fully charged, and the slowest is in more than three minutes. The charging time of the pocket charger is only about one hour.

How to corrode your brass vape mechanical tube mod to polish and clean so that it will not be oxidized by the sweat on your hands

by Martin Smith

Wanna mechanical vape tube mod free shipping, please visit https://www.buyecigkits.com/?subcats=Y&pcode_from_q=Y&pshort=Y&pfull=Y&pname=Y&pkeywords=Y&search_performed=Y&q=mech+tube&dispatch=products.search&security_hash=674c20fccf5f8d65f0e279f3c849e304

Many vapers who are accustomed to using red copper brass tube mechanical mods have a problem that the mod becomes ugly after oxidation, because the hand sweats too much and the mod always oxidizes very ugly, below is the brass vape mechanical tube mod corroded

Next, buyecigkits will teach you how to corrode your brass and copper mechanical mod to polish and clean in case of being oxidized by the sweat on your hands, here we go.

First of all, we have to prepare salt and ammonia. Next are some auxiliary tools: protective gloves, petroleum jelly, small watering can, heating wire, sandpaper, gas mask, plastic box, Varnish.

We need to be in a ventilated place, outdoors, or in a ventilated garage or laboratory. Remember to ventilate. If you don’t have this condition, remember to use a gas mask. After all, ammonia is poisonous.

We can start to corrode when we prepare the above things!

1. Use sandpaper to grind the surface of the tube mod to be corroded and keep the surface clean to facilitate the subsequent reaction of ammonium salt and copper.
2. Spread 7-8 layers of paper towels on the bottom of the plastic box, sprinkle ammonia on the surface (be careful to use a watering can) to moisten the paper towels below, and then sprinkle a layer of salt to cover the entire bottom.
3. Use heating wires to pull two beams in the box for standing the tube mod.
4. Put petroleum jelly on the inside of the tube mod and make the threaded part thicker to prevent it from being corroded.
5. Put the processed tube mod in a plastic box without touching the bottom, and sprinkle a circle of ammonia on the surface of the tube mod and then evenly sprinkle a layer of salt, then there is nothing to do but wait.
6. Flip the tube every four hours. After 12 hours, the corrosion is complete. If the corrosion effect is too short, it will turn black if the time is too long.
7. Wash off the salt and ammonia on the surface with clean water and use a paper towel to absorb the moisture inside and outside, and let it dry.
8. Spray varnish on the surface of the dried mod. Please google how to spray. The adhesion on the surface of the mod after corrosion is easy to be rubbed off and contact with the skin, which is harmful to health. So use the varnish as a protective layer.

Generally speaking, its structure from top to bottom is as follows: drip tip, top cap, air flow cap, build deck with O-ring, glass tube, 510 connectors.

There is no difference between the upper part of the RDTA and the drip tip atomizer, which are the air flow cap and the build deck. The post has holes (usually four) at both ends of the buid deck to extend the vape juice guide cotton into the lower portion of air flow cap to absorb e-liquid.

The cap usually covers the build deck including most part of the post, on the one hand, it is exclusively designed for aesthetics, and on the other hand, it plays a role of sealing the refilling port on post , and the top cap and air flow cap is usually connected by two aprons, and the airflow is in the middle of the two aprons to ensure airtightness. 

The build deck is commonly connected with U-shaped double-column four-hole post, which can provide a simple and convenient wicking.

The tank is usually composed of the build deck, the glass tube, and an O-ring, which are connected with a rubber ring and 510 thread.

The middle of the base RDTA tank is the 510 connector with 510 thread

How many kinds of cannabis oil are there? And how to distinguish?

by Martin Smith
Many people will see the following options when buying:

Wanna buy the CBD product free shipping, click the button below or https://www.buyecigkits.com/CBD-Product

Hemp oil: The oil extracted from the flower stems and leaves of industrial hemp, that is, hemp oil contains different concentrations of CBD and almost no THC.
It can be called full-spectrum cannabidiol oil, which contains a variety of cannabinoids and terpene phenols, which can have a synergistic effect with CBD!

Hemp seed oil:
The oil extracted from hemp seed contains almost no CBD and THC (similar to poppy seed oil), but it is rich in bile fatty acids. It is mostly used in cosmetics and skincare products, and can also be used as edible oil

Cannabis oil: The oil extracted from recreational marijuana contains different concentrations of CBD and THC, and CBD is an anti-drug compound, which has a certain elimination effect on THC!

CBD oil: It can be extracted from cannabis and hemp. At present, it is extracted from hemp in China, and it can be extracted from cannabis and hemp in most states of the United States!

THC oil: extracted from cannabis, almost no CBD

The following key point is CBD oil
There are many types of CBD oil, roughly as follows:
1. Full-spectrum cannabidiol oil;
2. Broad-spectrum cannabidiol oil;
3. Pure isolate CBD oil;
4. Cannabidiol isolate

1. Full Spectrum Cannabidiol Oil:
Full Spectrum Cannabidiol Oil is a hemp flower leaf extract without further purification and separation. In addition to CBD (cannabidiol), it also contains terpenes, other cannabinoids, vitamins, minerals, fatty acids, phytonutrients, etc. Other substances extracted from the cannabis plant. Full-spectrum CBD oil is usually thicker, darker in color, and has a plant taste of hemp.
Because it contains the integrity of natural cannabinoids, the whole plant hemp extract contains a small amount of THC (tetrahydrocannabinol), but there is no hallucinogenic risk of THC.

2. Broad Spectrum Cannabidiol Oil:
Broad Spectrum Cannabidiol Oil, like Full Spectrum Cannabidiol Oil, contains a series of cannabinoids and terpenes but does not contain THC. There are also other products based on the separated CBD with additional cannabinoids and terpenes added.

3. Pure isolate CBD oil:
Pure CBD Isolate Oil is to separate and purify CBD crystals from hemp flower leaves, the purity of CBD can be as high as 99.9%, and then the CBD crystals are dissolved in oil solvents. Pure CBD oil only contains CBD and does not contain any other ingredients in hemp. Since CBD crystals are colorless and tasteless, the color and taste of pure CBD oil depend on the solvents and other additives used. Commonly used solvents are coconut oil (MCT oil), olive oil, hemp oil and VG/PG.

4. Cannabidiol isolate:
Cannabidiol isolate refers to the separation of CBD from cannabis extract, and the removal of cannabinoids, terpenes and other cannabis components. The finished product contains only about 99% or more of the fine white powder of CBD. CBD isolate contains only one cannabinoid CBD. It has no smell and taste and can be used to make various CBD-derived products, such as food, beverages, skin care products, etc.

It has been two years since IQOS quietly enjoy great popularity all over the world, especially in Japan and China in 2017. However, many people still can’t distinguish between heating not burn(referred to as HNB) devices and e-cigarettes. What makes things worse is even many official media did not give a clear positioning, instead they cited some confusing chemical names.

This blog will analyze the difference between e-cigarettes and HNB tobacco heating devices, and how to distinguish them.

E-cigarettes have been in mass production for more than ten years, and they have been committed to letting everyone experience simulated cigarettes while reducing the harm caused by cigarettes. Generally speaking, any product that uses electronic methods to generate smoke and use it as a substitute for cigarettes, smoke reduction, and smoking cessation can be called "electronic cigarettes." so the tobacco heated device that has only recently appeared is also a kind of electronic cigarette in terms of this concept.

The term "electronic cigarette" first appeared, and then the word "tobacco heating not burn device" appeared.

In fact, the term "heated tobacco" was "labeled" after the emergence of "Marlboro Electronic Cigarette" IQOS and its popularity around the world.

The birth and promotion of IQOS are mainly to advertise Heat not Burn, by heating tobacco instead of burning tobacco to produce smoke, which can reduce a lot of harmful substances produced by burning tobacco, such as carbon monoxide, carbon dioxide and so on. And this type of device and cartridges is called the tobacco heated not burn device and heatstick respectively to distinguish the traditional burning cigarettes.

The special background and identity tobacco heat not burn device 
The first tobacco heated not burn device is Philip Morris International’s IQOS and British American Tobacco’s GLO. Later, Korea’s KT&G’s FIIT and National Tobacco’s several brands joined the battle.

Obviously, those who develop HNB devices are all giants in the tobacco industry. It is obvious that it is not a business that individuals or small companies can easily get involved in since tobacco production and sales are strictly controlled in many countries around the world. 

So to sum up, the point is here. Based on the current market conditions, HNB devices refer to the specific matching heater on which tobacco heatsticks with a filter produced by tobacco manufacturers and made into a round bar shape similar to traditional cigarettes is heated and used.

Electronic cigarettes refer to traditional e-cigarettes, in which the injected e-liquid is heated and atomized by an atomizer to allow people to vape.
