Tips From Pro Vapers

You thought that it was going to be simple, right

You will just buy a vape pen, get some e-liquids in flavors that you like, and Bob’s your uncle! Well, now that you’re vaping, things don’t seem to be exactly right, do they? Sure, you’re off the stinkies but there’s something not quite right: maybe the flavors you’re vaping on are muted? Maybe you’re not getting enough nicotine? Maybe the drag feels a bit tight - or even too free?

Beginner vapers have it tough but that’s why we’re here - to help!

All in all, vaping IS easy and simple - up to a point and depending on what you expect from it. However, there’s a difference between simply and vaping in a completely satisfying way. The former approach works for occasional vapers - people who want something that will substitute a cigarette for a short period of time while they are quitting. Still, you can only become a true vaping aficionado once you drill down to the nitty-gritty and find out what makes vaping tick.

The big part of that is your vape juice - vape device pairing. More specifically, you need to know which vape juices work for what tanks. So the question: ‘What vape juice is right for my tank’ becomes increasingly important once you start accumulating some vape gear and want to get the best out of every single setup.

The answer here is slightly complicated and depends on several things:

  • The vape tank that you’re using - different types of tanks are tailored toward different vaping preferences. They will differ in vaping power, cloud production, size, ease of use, and more.
  • The ingredients in your vape juice - there are two principal ingredients in vape juice, so-called base liquids. Those are vegetable glycerin (VG) and propylene glycol (PG). The percentages can vary (most vape juices use both to some degree) and your vaping experience will vary along with them.
  • The amount of airflow - do you like your draw tight or do you prefer something that’s a bit more free-flowing? The level of customizability is important because it will determine what type of vape juice you should use.
  • Nicotine feel and requirements - do you like to feel the nicotine while you’re vaping (e.g. strong throat hit)? Or, do you prefer to have it in the background? Your nicotine dependency will play a huge part here because there are certain types of tanks that work best with high-nicotine juices. In fact, there are even certain types of nicotine bases that you will, most likely, prefer if you’re a 2-pack a day smoker, but we’ll get to that in a minute.

A delicate interplay of all these elements will, in the end, determine which vape juices are best for you. The real question here is - what are you really after?

What Do You Want From Your Vape?

To ensure that your transition to vaping is successful, you first need to understand what you want from it. That will play a huge part when you’re picking the right e-liquid for your tank.

Typically, you can swing one of three ways:

  • Looking for a psychological sensation similar to smoking- not just in the feel, but in the look as well. If you’re accustomed to holding a cigarette, you will prefer vape pens and a bit of a throat hit.
  • Emphasis on flavors and vapor - you’re not in it for the nicotine - you simply want to enjoy in a ton of flavors that are available and get the ultimate kick out of blowing huge clouds. Your ideal set-up is a really good sub-ohm tank and a high PG/high VG vape juice, depending on whether you prefer flavor or vapor.
  • Searching for the ultimate nicotine hit - you’re not into the ‘feeling’ of smoking. Also, you’re not a big fan of clouds and flavor. What you need is a whopper nicotine fix every now and then and you want it to be available as fast as possible. Well, your best bet are the new closed pod systems filled with nicotine salts.

Vape Tanks Play an Important Part

There is a ton of vape tanks on the market - M2L tanks, sub-ohm tanks, RTAs, RDAs, RDTAs, you name it. Some of these abbreviations might even ring a bell because they are widely used by vaping veterans. In any case, we’ll focus on three distinct types - the rest probably don’t interest you since they don’t come with premade coils, and require you to build your own with the help of vaping wire and a firm understanding of Ohm’s Law.

So, three types of tanks that use premade coils are:

  • Mouth to lung tanks - M2L tanks are 2nd generation tanks that look something like an oversized pen cap. Take a look at the image for reference:Mouth to Lung M2L Vape Device

    These tanks have a few things going for them, especially if you’re looking for something as similar to smoking as possible:

    • They use vape juice conservatively
    • Don’t produce too much vapor
    • Have a restricted airflow similar to combustibles
    • Designed for use with high PG liquids (lower viscosity)
    • Can be used with high-nicotine e-liquids (12mg and up)
    • Coil resistance almost always 1 Ohm and up


  • Sub-Ohm (or direct to lung) tanks- D2L tanks are usually cloud beasts that rely on high VG juices to live up to the wildest dreams of cloud-chasers. They are a bit more robust and some of them can be used with premade coils AND custom, home-built coils. We recommend sticking to factory coils until you know a bit more about (we’re guessing you’re not there since you’re still confused about which e liquid to use with which tank). Here’s an image of a modern, hyped-up sub-ohm tank: Sub oHm Tank
    • Coils under 1 Ohm - plenty of vapor and flavor
    • Vape juice guzzler
    • Airflow completely customizable
    • For use with high-powered mods (not vape pens)
    • Designed for direct to lung inhales
    • Best suited for low nicotine vape juices (3mg or no mg)


  • Closed pod systems- last, but not the least, are closed pod systems. They are a bit of an innovation, with most brands being available somewhere around mid-2017 onward. They are the next step in the evolution of vapes and here’s how they look like: Technically, the whole system is called the pod system. The tank, in this case, is the disposable pod that’s attached to the battery. Byrd Pod SystemAbove you can see the Byrd by Space Jam. (Full review about Space Jam Eliquid's The BYRD here)
    • Filled with nicotine salts - up to 60mg of nicotine
    • Use disposable pods, no refilling
    • Each pod comes with its own coil (around 1 Ohm)
    • Good throat hit, similar to a cigarette
    • Best nicotine delivery system among vapes


What Is Really In That Vape Juice of Yours?

Not every tank can handle every vape juice. Because most e-liquids are a blend of VG and PG, the important thing to keep in mind are the percentages - they will determine whether a juice is better suited for a M2L or a D2L tank.

For example, propylene glycol is not very viscous, which means that it can safely be used with M2L tanks that usually have very constricted wicking holes and airflow. Since the whole point of M2L vaping is a feeling similar to smoking, there wouldn’t be much point in making those holes large - you just wouldn’t get that same sensation. That means that high VG juices - which are very thick and viscous - will have a hard time with M2L tanks.

High VG juices are better suited for D2L (sub-ohm tanks) for two reasons: a) they produce more vapor, and b) sub-ohm tanks are equipped to handle their viscosity. They can deliver enough power to them to evaporate them quicker and they have large enough wicking holes that will keep the cotton wet at all times - otherwise, you would frequently experience dry hits (horrible flavor that’s produced when e juice and cotton both catch on fire).

Also, PG has a bit more throat hit than VG, which is something to think about if you want to mimic the sensation of smoking without going overboard with nicotine.

In a nutshell - high PG for M2L and a smoke-like experience, and whatever you want for sub-ohm tanks, provided you keep in mind that you will get a better depth of flavor with PG and more vapor with VG.

What’s Airflow Got To Do With It?

At a first glance, not much, right?

But, of course it does.

Old (and new) M2L tanks don’t have much of an airflow, although they mostly feature an airflow control ring these days, to give you at least a semblance of customizability. The draw is tight, limited, and you can’t really hope for huge clouds. Again, if this is the case with your tank, you will want to stick to an e-liquid that’s low on vegetable glycerin.VG needs a lot of air circulation so it can evaporate better and create huge plumes of vapor.

On the other hand, sub ohm tanks will generally come with a ton of airflow, as well as the ability to customize it further. Some even have several points of entry (top or bottom) and more than one airflow control ring, just for kicks. It doesn’t really matter which type of vape juice you use here - high VG or high PG - as long as you keep in mind that more airflow means faster juice consumption. If you really love a certain flavor and it costs a pretty penny, you might want to turn that airflow down a bit. Also, low nic vape juices are the way to go if you like a lot of air breezing through your vape. Why? Well, that’s covered in our next point!

Nicotine - The Difference Between a Good Hit and a Cough Fit

Nicotine is a mostly harmless substance that got a bad reputation after hanging out with thousands of other toxins produced by cigarette smoke. It does have some effect on blood pressure and heart rate, although those effects are temporary. Due to its mostly benign nature (nicotine can even prevent certain neurological diseases, according to some studies), it can be safely used in e-liquids.

That said, you’ve got to know how to use vape juice with nicotine. Different strengths are best-suited for different types of tanks and, if you forget about that, you can say hello to a pretty spastic cough fit.

For example, high nicotine vape juices deliver something that is called a throat hit. Basically, it’s that tingling feeling you get when you smoke a cigarette. As you up the airflow, more vapor is deliver to your mouth and that tingling sensation quickly turns into burning. That’s why high nicotine e-liquids are best used with M2L tanks that have a very limited air intake. It’s very rare to see someone vaping on a 6 mg (or, God forbid, 9 mg) vape juice in a sub-ohm tank - there’s so much vapor coming in at a higher-than-normal temperature that the throat burn sensation would be almost unbearable. This means that people who like big clouds, but also need a good nicotine hit, are stuck between the rock and a hard place.

Or are they?

Luckily, with the invention of nicotine salts, this has changed. The problem with regular vape juice is that it uses freebase nicotine - a type of nicotine that becomes harsher and harsher as you up the strength. Nicotine salts, on the other hand, are much milder on the throat. Theoretically, you can go up to 60mg and feel only a mild throat hit, even if you’re using a sub-ohm tank. We say theoretically because even PG gives a bit of throat hit so it’s never a good idea to add oil to the fire.

In any case, most nic salts are packed in pods and used with closed pod systems, such as the Byrd or the JUUL. However, e-liquid manufacturers are increasingly creating stand-alone nic salt juices that can be used in specialized tanks. One such tank is the the Ego AIO Eco, which uses a 0.5 coil and plenty of airflow. Still, we recommend caution here - even though your ultimate goal might be to get a quick, potent nicotine fix, you don’t want to go for an overkill. Choose nic salts that are around 20 to 25 mg if you’re planning on using them in a sub-ohm setup (instead of immediately going for the 60mg bottle).

Create Your Own Perfect Vaping Experience

Ultimately, how you vape and which vape juice you use in your tank is totally up to you. There are as many vaping styles as there are vapers, so go wild. Still, that won’t stop us from offering some guidance in the form of this short recap:


  • Use M2L tanks with high PG juices if you’re looking for good flavor, little vapor, and an experience as similar to smoking (both in how it feels and in how it looks).


  • Use sub-ohm tanks with any type of vape juice (high VG is better for clouds) if you want a lot of vapor. Remember that more airflow equals more e-liquid consumption and, also, keep the nicotine content down if you don’t want to burn a hole in your throat.


  • Go with closed pod systems if you’re looking for a potent nicotine fix. Alternatively, get a nic salt vape juice and use it in your sub-ohm tank if you want clouds AND a throat hit, but remember to keep your air flow and power on medium and don’t go over 20 - 30 mg nicotine.

    There you have it: everything you need to know about vape juice and which type of tank to use it with. Now, go ahead and visit BuyVapor - we stock some of the best vape juice brands on the market and you will even find a select few vape nicotine salts in our offer!
