When choosing the best atomizer don't start with what e-juice flavor, battery color, tank style, etc. you should be buying.
Forget about that for one second.
Let’s decide if you would prefer a quad, dual or single coil configuration first.
These are the three main categories for coil builds.
Quad and dual coils heat the liquid faster so you will get more vapor in a shorter amount of time. However the ease of single coils have their place among the most experience users even.
This seems pretty entry-level information, but that’s okay, it’s important to cover the basics and get on the right track foremost. You’ll be cloud chasing in no time!
Let’s cover the basics of the single coil first.
You might be thinking that single is lesser than the rest. Many vapes have different benefits. Just because there’s one coil doesn’t mean it’s any less optimizal than the rest.
Single coils tend to get hotter under lower wattages. Let’s say you have a large build , this is a huge plus, as dual coil large builds can require a ton of power to get hot.
Many prefer a single coil, as they only have to build and install one coil. This comes with the obvious advantage of saving money.
The third reason ties into the second when it comes to building. Being that it's much easier to get proper ohms on a single coil, as on most rebuildables, dual builds cut the ohm rating in half. This means a few things, but for now just keep in mind that it equates to a longer battery life on a single coil.
If you’re getting into using various kinds of wick, then perhaps the single coil is the way to go for testing. This is an easy to change out component in this respect.
Heat, chamber size, and airflow are all important aspects to consider on the build when thinking about implemented one coil, much more so when dealing with multiple.
Though it’s ultimately about preference, and many of us have varying taste let’s review some of the finer points:
- Saving Cash: Single Coil configurations will probably save anywhere from fifteen to thirty percent of battery power. Because one coil is making contact, the chances are likely that you’ll save on E-juice in the long run. A very important aspect to consider for the thrift vapers out there among us.
- Ease of Use: Single Coil builds requires less experience to rebuild, because of the simplicity in design. These are obviously going to be intuitive to the engineers at heart, but often vapers that start on these builds will grow to experiment and go big once they get comfortable. Call it a bug that we catch.
- Not blowing clouds: So why aren’t you running out to grab a single coil right now? Perhaps you’ve read that the density of vapor produced by a single coil configuration is much lower than with more coils.
That’s because the e-juice isn’t making contact with more than one coil. It’s pretty simple math. That doesn’t mean you’re getting low density of vapor though. The single coil is pretty much the standard.
- Heating Time: Although the time difference might not be significant enough or noticeable to a beginner, single coil configurations require a longer heating time. Many multi-coil users would wince at this, but if you’re simply getting into the hobby then it’s nothing to scare you away from a single coil.
As we said, it’s useful to start with a single coil to understand the nature of the builds and how they function. More and more though, users are reporting that their multi coil builds weren’t cutting it, via wasting batteries juice, etc. Maybe they’re just practicing poor kit hygiene. Find out for yourself!
Onward to the dual coil setup. While we’ve discussed some of the things obvious to you already, let’s recap.
Dual coil builds tend to create more vapor than a single coil. One thing to keep in the back of your mind is that when performing a dual coil build, it’s essential for both coils to be identical forms and sizes to ensure that they heat up properly.
Adding a second coil will typically result in halving the ohms, due to how resistance works, however it’s worth noting that some RBAs have a neutral center post, which will actually double the resistance (more on that down the line). Also, a dual coil setup will split up heat between two coils. Ultimately, your extra heating coil promotes more vapor production in e-cigarette. If you’re searching for dense vapor or trying to participate in some cloud chasing, then this is the right path to be on.
Here’s the basics on resistance:
If your device has a higher ohm rating, the more resistance it has.
The more resistance an atomizer has, the less power the battery will be capable of passing through to the tip of your tank.
Now that we’ve briefly touched on resistance let’s cover the highlights:
- Dual Coil configuration are going to yield a higher vapor hit. More contact area on the coils means contact area between e-juice and coils is optimized.
- Quicker and More Often: Overall, Dual Coil configurations tend to deliver same amount of vapor in a shorter time. Same principle applies; two coils transfer heat faster than a single coil, therefore, heating time is lower.
- Battery depletion is typically higher and faster.
- More juice is vaporized in order to produce a thicker cloud of vapor, but that leads to just stocking up on more e-juice ;)
- Dual Coil configuration is harder to rebuild since it has two coils instead of one.
By now you might be thinking you’ve got it all figured out. More coils means lower resistance, equates to quicker battery use. The vape here is warmer, more vapor. And a more difficult build. But that’s not all.
The trend towards multiple coils started around 2015, and it’s been met with mixed reviews.
Quad coils are certainly more difficult to build. There’s a huge faction of vapers that consider going this route a waste of time, and you’ll run into a litany of problems, like described above: going through batteries and e-liquid quickly.
So why would anyone prefer this kind of build? The answer is simple. These are among the most powerful coil build of all. This is where many users are able to get massive clouds,seen from blocks away. The is the competitive build.
One could even pursue more coils. Though it’s a matter of experience. If Tesla was still around you might imagine him building huge contraptions to vape, maybe control the weather with his coils. Still, we’re far off from that kind of thing without him around!
What Kinds of Coils Are There for Vaping?
Whatever brand or manufacturer you go with for your tank, they will often provide stock coil heads to screw into your tank deck.
Stock coils will typically last two to four weeks at best. This all depends on how much you vape, the juice you use and wattage you’re running.
Some tanks will come with a section that will allow you to build and wick your own coils, rather than using their stock coils. This is called an RBA: meaning Rebuildable Atomizer. ReBuildable Atomizers are an important category of vaping atomizer systems.
Back in the stone age of vaping, when power tools were the go to… actually fast forward a bit. Before store-bought drop-in coils became as common as they are today, RBAs were the only way to get a cloud chasing vape.
Today, RBAs are widely used all over the planet.
What do ohms have to do with vaping?
Above-ohm vaping, or vaping with a device that uses coils that read at 1 ohm or higher is where most vapers began at one time or another. Though coils can be anywhere over one ohm, the most common coils read either 1.8 ohms or 2.5 ohms.
You should keep in mind that coils should not get red hot while they are wicked and juiced.
Rebuildable coil heads (RBA)
Some tanks, such as INSERT APPLICABLE PRODUCT LINK allow you to build your own coils and wick them with whatever medium of cotton you’d like, rather that using their stock prebuilt coils.
Here’s a good tool list to have on hand if you’re ready to start delving into into performing rebuilds:
Resistance wire – kanthal (a blend of iron alloy), stainless steel, nickel, nichrome, etc.
Tweezers – preferably ceramic tipped, to pinch your coils and also for some of the harder to reach aspects of the projects.
Small metal rod – a small screwdriver, or coiling tool that you can find from just about any vape store.
Organic cotton – or whichever wicking material you prefer there’s a plethora to choose from.
Scissors and Wire Cutters– for trimming cotton and wire, respectively.
Investing in an ohm reader or an voltmeter is advisable– (hint: some mods actually detect resistance in real time so keep your eye out for such handy tech).
Having these on hand will really help you
So in conclusion, the great debate between single, dual, or quad coil will forever rage on. Some of the finer points of our breakdown of the topic include:
More coils typically mean the vapor will be denser and because more of the liquid is being used the flavor will be stronger.
However the drawbacks are that you will use more e-liquid and the battery will deplete much quicker.
More coils means a greater area is heating the liquid the temperature of the vapor will be much hotter and you will have a stronger throat hit. This can be a pro or con depending on your own preferences.
If you want to rebuild your own coils then a single coil setup will be easier to build. Especially if it’s your first time.
It is recommended that you try both single and dual vape coil configurations to really understand the difference. You never know what your preference is going to end up being.
