What is the Best RTA Available in 2021?
After comparing hundreds of RTA’s, we have selected our favourite tanks available right now.
#1 Geekvape - Zeus X Mesh RTA
- Easy top-fill design
- Easy to wick
- Simple to build
- Excellent build quality
- It comes with a 4.5ml bubble tank
- Multiple sets of spare parts
- Good airflow control
- Great taste
- No coil cutter
The Zeus X is the third iteration of Geekvape’s, you guessed it, Zeus line.
At 25mm of diameter, this big boy is made of stainless steel, has a maximum juice capacity of 4ml, and has the option to be configured into either a single or dual coil build.
Due to its design, this thing is pretty much leak proof. Using a “chimney inside a chimney” design all but guarantees that shaking around your RTA isn’t going to make it spew juice everywhere.
That said, it’s still possible to flood the chamber, so make sure you use plenty of cotton.
The tank itself is spacious enough you can stuff it without worrying too much.
Performance-wise, I can’t complain. As RTAs intended for dual coil use can cause some burning, I decided to stick with using two coils.
Vapour production is excellent, and the taste is also something I can’t complain about. As for the body, the Zeus fits perfectly in my hand, and the grip feels secure.
The method used to top fill the tank is also super convenient. Instead of screwing off completely, this RTA uses a quarter-turn design to make filling up the tank an easier endeavour. This build is also simple to take apart and put back together.
The ease of maintenance of rebuilding is a major plus in my book because while tinkering is fun, there’s only so many times I can build an RTA and shout, “It’s alive!”
Don’t judge me. We’ve all done the giddy dance after putting together our first rebuildable.
Best Leak-Resistant Design
#2 Augvape & Mike Vapes - Intake RTA
- Good flavour
- Is leak-resistant
- Clever airflow system
- Good vapour production
- Lots of space for a coil
- Easy to open and fill
- Easy to overwick
- Can’t install dual coils
This RTA happens to be a collaboration piece from Augvape and Mike, hence the name.
It uses a clever design to circulate air from the top vents all the way to the bottom underneath the coil.
This airflow system makes this RTA leak-resistant and also enhances the flavour compared to traditional top flow systems.
At a 24mm diameter, this product comes standard with both a 2.5 and 4.2ml tank. It’s a single coil system that is also fairly simple to build.
I haven’t had any problems installing a coil, but one downside is that this RTA doesn’t come with a prebuilt coil.
It was a minor inconvenience, sure, but that didn’t stop me from grumbling as I built a coil from scratch.
Now I said before that the Intake measures 24mm in diameter, but it gets a little fatter around the bubble tank at 26mm.
It’s not a major issue for me, especially with the excellent build quality of this RTA. Something I was leery of, though, was the low profile drip tips.
Most drip tips of this type have problems with heat buildup. It’s not exactly the kind of scorching kiss you’re looking for either.
However, the Intake design makes this a non-issue, but you can still use taller 510 or 810 drip tips for your peace of mind.
Best For Beginners
#3 Vandy Vape - Kylin V2 RTA
- Excellent build quality
- Very easy to put together
- Great flavour
- Coil lead cutting tool included
- Bubble glass included
- It comes with a premade coil!
- 3ml tank is small for dual coil
- But it doesn’t come with cotton!
From Vandy Vape, the Kylin V2 is the newest iteration of the line. It boasts improved flavour, performance, easier to use build deck, and addresses the leaking issue of the first version.
The V2 measures in at 24mm, and the tank can carry 5ml worth of juice.
This holding capacity of this tank doesn’t come without a price. The middle of the bubble tank folds out like a particularly fat roll that measures 30mm of girth.
If this bothers you, it also comes with a slimmer 3ml tank.
So, upon opening up the goodies, the first thing I noticed off the bat was the postless build deck. Being a quad terminal, this RTA can be configured in single or dual coil mode.
I’ve had a few issues before with postless decks, and while I generally have good experiences with them, there were a few times where I had trouble with pre-cutting my leads.
That wasn’t a problem with this RTA. The package comes with a well-labelled measuring tool that made cutting the leads a cinch.
Another possible problem I thought I might have was installing the leads, but it was an overall smooth process. The wicking process also didn’t pose any difficulties.
In fact, this entire build caused me very little trouble to put together.
This ease of installation makes Kylin V2 great for beginners, and I wholeheartedly encourage looking deeper into this product if you’re new to rebuilding.
Best For Flavour & Clouds
#4 Dovpo - Blotto RTA
- Easy to build
- Doesn’t leak
- Flavour is excellent
- Can fit bigger coils
- Comes with numerous addons
- No Coils included
Designed by Australian vaping royalty, Vaping Bogan, the Dovpo Blotto combines great aesthetics with outstanding performance.
The Blotto performs well with both single or dual coil builds. Recommended for beginners, this tank is straightforward to build and just as simple to wick.
The RTA is 25mm in diameter, so it works well with most vape mods. Its top fill design and 6.5ml capacity make it a pleasure to vape with.
The airflow from the 242-degree deck makes the flavours pop and produces plumes of vapour on this fantastic RTA.
In the box, you get glass & Ultem bubble tanks, plus a 2ml straight glass tank.
The Blotto is hands down one of the better tasting RTAs I’ve gotten my hands on.
Best Restricted MTL Draw
#5 Vandy Vape - Berserker BSKR V2
- Great for Mouth To Lung Vapers
- Deep flavour
- Easy to take down
- Airflow control ring tight
Our last pick will appeal to those looking for a Mouth To Lung (MTL) draw. The Berserker range of RTA’s from Vandy Vape is specially designed for a tight draw with a restricted chamber that produces fantastic flavour.
Moldavian YouTuber Alex has designed each new version of the popular Berseker family of tanks from VapersMD, and this is the best yet.
When the airflow is set to the largest setting, the V2 mimics the pull of an analog cigarette almost perfectly, so for anyone looking to recreate that feeling, this is the RTA for you.
The build quality is top-notch. Everything feels quality with no leaking on our test tank.
The Berserker V2 is 24 mm in diameter and fits up to 3 mL of juice.
My Personal Favourite RTA Tank
I’m going to have to pin the Geekvape Zeus X as the winner of this roundup. When it comes to the overall convenience factor, this RTA edges out at the top of the competition.
While the Kylin V2 may have slightly more tank capacity, the Zeus X has more than enough to be comfortable while being slimmer.
Refilling the tank is also ridiculously easy due to its design. Furthermore, this atomiser hasn’t leaked yet in my experience, and I doubt it will unless I put it through a serious torture test.
The Zeus X is also easy to build and take apart. While the OFRF Gear is renowned for its ease of buildability, breaking it down can be a real chore.
And when comparing the two in regards to juice taste, I can’t say Geekvape’s RTA loses out in any major way.
RTA Tank Buying Guide
What Is An RTA?
An RTA is a type of Rebuildable Atomiser (RBA). The short version is that an RBA system allows you to build your own coils.
Literally, you take a coil, wrap it, tack it onto a device, and thread a wick through said coil.
Now the big difference between the types of RBAs is how you feed the wick.
As noted by the acronym, an RTA is a tank type of feed system that uses a rebuildable coil. After building your atomiser, all you need to do is to screw off the top, access the tank, and fill it with e-juice. Then you vape, use up the liquid and go for a refill once you’re out.
Types Of RTA Configurations
The beauty of building your own atomiser is that you know exactly what you want in the finished product.
There is a whole slew of nifty things you can do to customise your vape to your liking.
Airflow, Top Or Bottom?
There are two ways you can go about introducing airflow to your RTA.
The top system draws in air from the top or sides of the coil. While this system helps to prevent leaking issues, some designs end up messing up the flavour as the coil may start burning the wick.
A bottom system draws air in from under the coils. This system ensures maximum flavour by moving air from beneath the coils to cool them while drawing in e-juice through the wick simultaneously.
Though this system tends to leak, properly building your RTA will minimise this chance greatly.
Direct Lung And Mouth To Lung
This topic concerns the size and number of the airflow holes that you’re pulling from. Smaller and less numerous holes are designed for a mouth to lung style of vaping.
Atomisers with bigger, more numerous air channels produce more vapour. It is also geared towards vapers who tend to use the direct lung technique.
RTA And Genesis (GTA)
The difference between these two types of builds is the difference in atomiser placement.
RTAs are placed directly on the build deck. This leaves less room for a wick, so the cotton tends to be shorter on this build.
GTAs use a raised deck that places the atomiser higher up in the tank. This allows extra room for a longer wick which lets your device soak up more e-juice.
Number Of Coils
Most RTAs use either a single or double coil as heating elements. The key differences between the two are what type of draw they are meant for, the amount of airflow, and vapour production.
A single coil build is geared towards mouth to lung draws due to the decreased contact with air.
This also means that vapour production isn’t as great as a double coil design.
Double coils are meant to do the opposite. While you can use them for mouth to lung, they are primarily meant for increased vapour production, which leans towards the direct lung technique.
Advantages Of An RTA
One of the major selling points true of all RBA is that they end up saving you money.
Compared to sub-ohm tanks with their replaceable coils, building your own is a much cheaper alternative.
You can get a coil roll and a bag of cotton for about the same price as a pack of proprietary coils.
Except the abundance of material means they can last you for months at the very least.
Moving on, the greatest advantage that an RTA has over other builds is convenience.
Compared to a rebuildable drip atomiser (RDA), the tank type build has a far larger e-liquid capacity.
Instead of having to drip fresh liquid every few draws, an RTA allows you to vape all day without carrying your juice with you.
Even rebuildable drip tank atomisers (RDTA) beat out in the instance of compatibility. RTAs are generally smaller and easier to wick than they’re bigger, do it all, brother.
Disadvantages Of An RTA
Regrettably, an RTA has a major weakness compared to the other kinds of RBAs you can build. Namely, cloud size.
Trading vapour production for convenience, an RTA isn’t quite as good as an RDA at producing huge, voluminous clouds. Given it has more parts than an RDA, tank atomisers require a little more skill to put together, but that’s a minor nitpick.
If you want a combination of not having redrip every few puffs, a compact size, and overall cheapness, an RTA device will suit your needs well.
