Get great flavor and vapor with these high-performing rebuildable tank atomizers
Rebuildable Tank Atomizers (RTAs) are shaping up to be the big thing in vaping in 2020 and it’s easy to understand why. RTAs bring together the customizability and flavor of an RDA, with the ease of use and convenience of a refillable tank.
However, unlike your traditional sub-ohm tank, there are no ready-to-use pre-built coils that you can purchase from the store. Instead, you’ll have to build your coils yourself, wick them, and mount them on the deck. After that, it’s simply a matter of putting the RTA back together, and filling it up with your favorite ejuice!
Now while this may sound complicated to a complete beginner, believe me when I say that it’s not. Building your own coils is easy with a bit of practice, and provides many advantages over your typical pre-made coils. Cost effectiveness, improved flavor, and customization options are just some of the many reasons why building your own coils is the way to go.
We’ve created this list of the best RTAs 2020 as a guide for those with sub-ohm tanks who are looking to purchase their first RTA, or for RDA users looking for a tank with a little more convenience. Additionally, if you already use an RTA and are shopping for a new one, you’ll definitely find a new RTA that you like.
For our list of the best RTAs 2020, we’ve divided them up into two categories: the best single coil RTAs and the best dual coil RTAs. These RTAs have been selected based on their build quality, ease of use, flavor and cloud production. So no matter what you’re looking for, these RTAs will satisfy your needs.
Best Dual Coil RTAs
WHY TRUST US
All of our reviews are based on market research, expert input, or practical experience with most products we include. This way, we offer genuine, accurate guides to help you find the best picks.
The Blotto is a dual coil RTA manufactured by Dovpo and designed by popular vape Youtuber Vaping Bogan. Everything about this tank is big! It’s got a 26mm base diameter, a 6ml tank capacity and large fill ports that will fit any type of ejuice bottle. It’s truly a “go big or go home” type of tank.
The standout feature of the Blotto is its 242° airflow design. On both sides of the build deck is a wall that rises and ‘hugs’ your coils. There are airflow holes in these walls, as well as in the base of the build deck. This forces air to hit your coils from 242 degrees and delivers absolute monster flavor and clouds.
The build deck is funneled air from two extremely wide slots that are located at the base of the tank. Each slot is made up of 26 holes arranged in a honeycomb pattern. With the airflow completely open, you get a slightly restricted direct lung draw that is both smooth and quiet.
There’s a bit of a learning curve to wicking the Blotto correctly but the performance is worth learning for. All things considered, the Blotto is our top pick for the best dual coil RTA of 2020.

The Profile Unity RTA is a collaboration between some of the biggest names in vaping. Mr.JustRight1 (the creator of the Profile 1.5 RDA) and TVC (responsible for the Drop RDA) have teamed up with Wotofo to create one of the best RTAs of recent times. You can build single, dual, or mesh coils on the deck.
It’s got a 25mm diameter that retains the same convenient build deck as its RDA counterpart; a dual clamp, mesh coil compatible deck with a spring-loaded central support platform. This platform applies constant pressure to your cotton which ensures that it’s always in contact with your mesh for optimal performance and flavor.
The body of the Profile Unity has two notches that align with the base of the tank to secure the top cap and also ensures that airflow is always properly directed to your coil. It’s got a 3.5ml standard capacity that can be expanded up to 5ml with the included glass tank section. Wicking the Profile Unity right can be a little tricky at first. However, once you get the hang of it you’ll never go back to using another RTA.
Top & bottom wicking
Great restricted lung hits
Uses a lot of e-juice
The GeekVape Zeus X is the successor to the appraised Zeus Dual and is the latest addition to the Zeus family. It brings a 25mm diameter and an updated postless deck designed to accommodate large, complex builds. There are four terminals so you can use either single or dual coils and the screws are side-secured for easy building.
The airflow on the Zeus X is perhaps its best feature. First off, it’s leak-proof thanks to its top airflow design. Secondly, the air from these two top airflow slots is directed through multiple holes in the chimney, then to your coil and out the mouthpiece. This results in tremendous vapor production and also enhances flavor. With the Zeus X you get nothing but good, smooth draws.
With its 4ml max capacity this RTA will hold more than enough ejuice to get most vapers through their day and makes a great tank for any rebuildable lover. It’s reliable, easy to build on and it vapes like a beast — that’s the Zeus X RTA.

The Widowmaker is a 25mm RTA produced by Vandy Vape and designed by El Mono Vapeador. Out of the box, the Widowmaker has two honeycomb-style side airflow slots that are fully adjustable. But it also comes with two additional side airflow rings that can be swapped in: one with a large 4ml hole, and one with a small horizontal slot.
The Widowmaker also has a bottom airflow control ring with 7 holes that can be adjusted to your preference. The airflow options on this RTA are unparalleled and allow you to fine tune your draw just the way you like it.
The Widowmaker has a postless build deck that is a breeze to build on. The bottom of the deck has 36 airflow holes arranged in three rows and this brings airflow in from the bottom airflow holes and directly underneath the coils. Paired with the side airflow, this airflow design results in flavorful, rich and concentrated vapor.
Filling the Widowmaker is simple and is done by removing the top cap with a quarter turn. High build-quality, numerous airflow options and impressive flavor are all reasons why the Widowmaker RTA is one of the best dual coil RTAs 2020.
Tons of airflow options
Solid build quality
It’s a tall tank!
Top airflow tanks are great because they’re virtually leakproof but they don’t provide the best flavor. The Intake Dual is different. It brings all the benefits of a top airflow RTA but with the flavor of a bottom airflow tank. Built into the deck are two large intake shafts that funnel air directly from the airflow holes & straight to the sides of the coils. This unique airflow design provides clean, bangin’ flavor — all from a dual coil RTA that doesn’t leak.
The build deck is clean and more straightforward than the original Intake so it’s really easy to use. Just drop a pair of coils into the postless build deck and secure the leads with the hex screws on the side. Augvape even include a coil measuring block in the package so there’s no guesswork needed to measure out the coils. And while some RTAs can be difficult to wick, this one isn’t; it wicks like a charm as long as the cotton is covering up the wicking holes.
As for the draw, it’s a restricted direct lung draw that will appeal to anyone who likes a tighter vape. It’s not as airy and open as the majority of RTAs on the market so if that’s your style, this tank isn’t for you. But if you like a constricted draw then this should be your number one pick.
Last but not least, the tank on the Intake Dual will hold a massive 5.8ml of eliquid for long, all-day usage without refilling. Because who doesn’t like room for more ejuice?
Nice restricted DL draw
Large 5.8ml capacity
Airflow might be too restricted for some
The Kylin V2 is a 24mm RTA by Vandy Vape, and features a great deck design that is super easy to use. The build deck on the Kylin V2 is postless, and features four terminals with side mounted screws. Now while it can be used with a single coil, the Kylin V2 really shines when used with a dual coil setup and will provide excellent flavor and vapor production.
The airflow on the Kylin consists of dual adjustable wide slots for intake. When you take a draw, centralized channels redirect airflow under your coils, while sloped outer channels concentrate and direct airflow to the sides of your coil. This clever design results in incredible flavor and some massive clouds, and is one of the main reasons why the Kylin V2 is so good.
The Kylin will hold 3ml of juice if you use the standard glass section. However, this can be expanded up to 5ml by using the included bubble glass. As for filling, the Kylin V2 RTA features a convenient slide-to-open, top fill design that is very user-friendly and hassle free. All in all, the Kylin V2 by Vandy Vape is a superb RTA, and definitely one of the best RTAs in 2020.

Dense, flavorful clouds
Easy to fill

Best Single Coil RTAs
The OFRF Gear has a large 3.5ml tank and a secure threaded fill port to prevent leaking. It features a four terminal build deck to allow for either clockwise or counterclockwise wrapped coils.The short airflow path increases vapor and enhances flavor. The Gear is definitely the best single coil RTA of 2020.
The OFRF Gear RTA is not only a looker, it’s also one of the best RTAs around. With a 24mm diameter and a postless build deck design, the Gear RTA is perfectly suited for single coil setups. There are four terminals on the build deck and this allows you to install either clockwise or counterclockwise coils without issue.
For airflow there are two wide airflow slots located at the base of the tank. The airflow is fully adjustable and can be restricted to suit your preference. Because of the Gear RTA’s small size, it has a short airflow path that increases vapor production and enhances flavor at the same time. It’s one of the most flavorful single coil RTAs to date.
The OFRF Gear has a 2.3ml standard ejuice capacity. However, this can be increased to 3.5ml with the use of the included bubble glass extension. The OFRF Gear is top filled and simply requires the top cap to be unscrewed in order to access the fill ports.

The Intake RTA is a collaboration between Augvape and popular YouTube vape personality and reviewer, Mike Vapes. The Intake is a single coil RTA and features a very unique two-post deck, with screws that clamp down on your leads. The aesthetics of the tank are beautiful, and feature nice grooves and lines.
Alongside its beauty, the hallmark feature of the Intake RTA is its airflow. While it is a top airflow tank, two tubes built into the deck funnel airflow from the top airflow slots, and out through holes located directly under your coil. The result is an RTA that literally “Intakes” air, and gives a flavor more comparable to bottom airflow tanks — without the leaking.
The Intake will hold 2.5ml of ejuice with the standard glass. However, it also comes with a bubble glass that will up this capacity to 4.5ml. In order to fill the Intake, simply twist off the top cap with a quarter-turn, and you can easily refill through the two large fill ports. For its ease of use, leak-proof design and amazing flavor, the Intake RTA claims its spot as one of the best RTAs of 2020.

The Cog is the latest single coil RTA from Wotofo and it’s perfect for those who like a loose MTL vape. This tank is especially designed for vapers who use nic salts or high nicotine ejuices at low to mid wattages.
With its 22mm base diameter the Wotofo Cog is a small tank and this concentrates the vapor and enhances the flavor of your draws. The deck consists of two spring loaded clamps and it’s really easy to build on. A 2.5mm to 3mm inner diameter coil fits perfectly.
The gear airflow control is the highlight of the Cog and also where it gets its name. This innovative airflow system works by twisting the base of the tank. When you twist, the inner gear mechanism rotates and aligns one of the five internal inlets with a passage that leads directly to the coil. The bottom of the Cog RTA is transparent so you can even see this in action! There are five airflow holes that you can vape with: 0.8mm, 1mm, 1.2mm, 1.4mm or 1.6mm.
The tank on the Cog MTL RTA holds 3ml of ejuice, and because this tank is meant for MTL vaping with low wattages, this is more than large enough to get through a day of vaping. When it comes to filling, the Cog has a secure threaded top cap that unscrews to reveal two large kidney shaped filling ports.
It’s beautiful styling, excellent flavor, and easy building make the Wotofo Cog a must have for any MTL vaper who loves single-coil RTAs.

Just like the Berserker Mini of last year, the Berserker V1.5 is small, good looking and extremely customizable. The BSKR V1.5 is a single coil RTA meant for MTL vaping at low watts and gives a nice, tight draw.
Included with the BSKR V1.5 are two 510 drip tips as well as two tank sections: one glass and one stainless steel. The glass section will hold 2.5ml of eliquid while the stainless steel section can hold 3ml. The stainless steel section completely seals off the tank and gives the BSKR V1.5 a cool and completely different look.
As it is meant for mouth-to-lung vaping, the build deck on the Berserker V1.5 will fit a single small coil. The build deck consists of two posts with a single terminal. Located directly below the coil is an airflow channel that condenses airflow for optimal flavor. The wicking ports are also perfect and will easily saturate your cotton.
The airflow on the Berserker Mini V1.5 is adjusted through two small airflow holes that increase in 0.2mm increments, ranging from 1.0-1.8mm — perfectly suited for MTL. If that’s your vape style you’ll love the BSKR V1.5.

Like its big brother the Kylin, the Kylin Mini delivers incredible flavor and an easy to use build deck. However, unlike the Kylin, the Kylin Mini is specifically designed to utilize only a single coil. Featuring a great postless deck design with a single terminal, the Kylin is beautifully machined and very user-friendly to build on.
A unique feature of the Kylin Mini is its “180° Honeycomb” airflow intake. Two, adjustable, wide airflow slots funnel air directly from the bottom of the tank. This air is then brought directly underneath your coils, as well as up and towards the chimney. This design results in some extremely flavorful and smooth draws.
The Kylin Mini will hold 3ml of ejuice with the stand glass section. However, this is expandable up to 5ml if you use the included replacement glass. To fill the Kylin Mini, simply undo the top cap and fill away! The top fill design is extremely easy to use. Overall, the Kylin Mini’s ease of use and top-notch flavor definitely make it one of the best single coil RTAs 2020.

The Pharaoh Mini is a single coil RTA and is available in a variety of different colors to suit your preference.

In order to fill the Pharaoh Mini, simply undo the top cap, and fill your desired ejuice. The Pharaoh Mini is a great RTA, and comes from two huge names in vaping that know their stuff.

What Is An RTA?
RTA stands for Rebuildable Tank Atomizer, and is a type of tank used in vaping. RTAs are best described as a mix of a rebuildable tank, and a refillable tank. Similar to RDAs, you build your own coils, and make your own wicks. However, there is no need to drip like in RDAs and you simply fill your tank and vape away.
RTAs generally look a lot like your typical sub-ohm tank, and offer the same large ejuice capacity and adjustable airflow control that you would expect from a refillable.
Why Use An RTA?
There are a number of reasons that make using an RTA the way to go. Now, if you’re new, don’t be frightened by the thought of building your own coils. It’s actually very simple to learn, and with some practice you’ll be able to make coils and wick them without a second thought. Building your own coils adds another level of customization to your vaping, and you can tailor the resistance to just the way you like it. Custom coils also give you the option of using coils with more surface area, which in turn will produce more vapor and flavor (check out clapton coils for a good starter coil).
Using an RTA also means that you don’t have to drip like in an RDA, but still get the flavor and clouds. With their large tank capacities, using an RTA can be more convenient than dripping with an RDA. Most RTAs have tank capacities around 4-5ml, and this will be more than enough to get you through even some high-wattage vaping sessions without having to refill.
