Sub-Ohm Tank, RTA, and RDA Tanks EXPLAINED

Best MTL Vape TanksPin

OK, so you’re new to vaping and you’re wondering what the difference is between sub-ohm tanks, RTA tanks, RDTA, and RDA tanks? Cool. Allow me to explain…

Table of Contents: 

The thing I like most about vaping is that it has something for everybody. It doesn’t matter your budget, there’s a vape setup perfectly suited to you. But picking one is harder than it looks, right? There’s just TOO MANY to choose from.

Well, this is where we come in – and below I’ll outline my favorite setups for each style of tank.

Cutting through the crap and finding the best in each category isn’t easy for most people. But we’re not most people. Among our writers, we’ve probably used over a thousand tanks – give or take.

And this means we’re in a great position to help guide you in finding the perfect vape tank.

But first, you NEED to know the differences between the different styles of tanks.

And for this, we’re going to take a look at each one in detail, so you know exactly what you’re dealing with.

We’ll start with the easiest to use first and work our way along in ascending order of difficulty (so the more advanced tanks are lower down)

Sub-Ohm Tanks – Ideal For 99.9% of People

The standard. The one most people use. Sub-Ohm tanks are convenient, easy to use in most cases, and come at a variety of price points, meaning they’re ideal if you’re vaping on a budget.

With a sub-ohm tank, you’ll be using pre-made coils which you buy separately for the tank.

These coils are packed with cotton and wire and, when heated by your mod, produce the vapor that makes vaping possible.

Now, sub-ohm tanks have developed A LOT over the years; they’re now very powerful, capable of handling power output well over 100W.

Most of the time, you’ll be running them anywhere from 50W-100W, though this will depend on your own preferences (and the resistance of the coils).

Sub-Ohm Tanks are ideal for beginners, as there’s no real messing around with them.

You install the coil, prime the coil, then screw it together, let it sit for five minutes so that the coil can absorb the E Juice, and then start vaping. And that’s it. Simple, right?

Sub-Ohm Tank Benefits

  • Easy to use – even for beginners
  • Great clouds and flavor with limited hassle
  • Lots of choices – there are literally hundreds of options
  • Extensive range of coil options for most big-league tanks
  • Big E Juice capacity
  • Great, all-around performance

Sub-Ohm Tanks Cons

  • Coils can be expensive; SMOK’s are $15 a pack (and you only get three)
  • Coils can burn out rather quickly, which can make running one expensive

Sub-Ohm Tanks: Bottomline?

Sub-Ohm Tanks are a great first option for anyone looking at getting into vaping, however, they aren’t without their problems.

99.9% of your issues will be coil related; they’ll burn out too quickly and end up costing you more than you expected.

For flavor and performance, however, a modern Sub-Ohm Tank is very hard to beat – especially when you factor in just how convenient they are.

You don’t have to drip E-Liquid on them very often and 99.9% of them have NO issues with leaking.

RDA Tanks – The Gold Standard For Flavor & Performance

RDA Tanks With BIG Juice WellsPin

An RDA tank is a completely different ball game to a sub-ohm tank.

They look different. They vape different. They’re basically completely different – and, yes, in a good way.

I predominantly use RDA tanks for one reason and one reason only: they’re super simple to live with.

Even more so if you buy pre-made Clapton or Alien coils from places like Amazon or your local vape shop.

With an RDA, you install your own coil, add your own wick, and then just splash on some E Juice, attach the top cap and you’re away.

You can make your own coils too, using wire, though I find this too time-consuming, however, many vapers swear by it.

RDA’s are actually the easiest tanks to use, even for a complete noob, as nothing can really go wrong.

You won’t get dry hits, you will get incredible flavor, and it will kick out A LOT of clouds.

And now, thanks to the rise of squonk mods, you no longer even have to drip E Juice, which is awesome.

This is why we’re seeing more and more RDAs come to market; squonking has made them incredibly popular!

As I said earlier: I use RDAs because they’re simple and they give the best flavor.

Chuck in the ability to squonk, and you’re looking at a near-perfect style of vape tank.


  • Amazing flavor and clouds – the gold standard, really.
  • Super easy to use
  • Saves you money – cotton and pre-made coils are WELL cheap
  • Lots of choices
  • You can get creative (make your own coils)
  • Predictable, reliable performance
  • Simple to look after and maintain


  • There is NO E Juice capacity – just small juice wells
  • Wicking takes practice
  • Decent RDA tanks can be pricey

RDA Tank Bottomline?

For me, RDA tanks are where it’s at. I love them, own many, and love vaping on them.

But they’re definitely not for everyone. If you’re intrigued by the flavor and performance, and the fact they’re cheaper to run than a sub-ohm tank, give one a whirl. You won’t be disappointed.

RTA Tanks

Out of ALL the tanks on this list, RTAs are the ones that will cause the most trouble for newbie vapers.

On paper, they sound like perfection: sub-ohm tank-style juice capacity with an RDA style deck. The perfect tank, right?


Don’t get me wrong, there are plenty of amazing RTA tank options around.

And most of them work great. But for those new to vaping, I’d advise you to give them a wide birth, as they are fiddly as hell and are prone to leaking. A LOT.

Unless you go with the Augvape INTAKE RTA which is 100% leak-proof and super-simple to setup.

An RTA tank works in a similar fashion to an RDA, in that you have to install your own coils.

Unlike RDA tanks, though, RTA tanks have sub-ohm style juice capacity, meaning you can fill them up and vape all day without ever having to reach for your E Juice bottle.

If you can get one working properly, they are brilliant. The perfect balance of convenience, performance, and flavor.

They’re just tricky to set up and live with (in most cases) and, because you’re reading this article, I’m guessing you’re pretty new to all this.

My advice here is simple: wait – get some experience under your belt first, then have a look at an RTA.


  • Sub-ohm level juice capacity, RDA-grade flavor, and clouds
  • Cheaper to run than sub-ohm tanks
  • Tons of options to choose from
  • Available at competitive prices
  • When they work, they’re brilliant


  • Can be very tricky to set up (some more so than others)
  • They’re prone to leaking. A LOT
  • Higher chance of dry hits versus RDA or Sub-Ohm Tank

RTA Tank Bottomline?

RTA tanks are easily the most annoying to live and work with.

They require a good eye, finesse, and, above all else, the input of someone that knows what they’re doing with their coil builds and wicking.

Definitely not one for the novice vaper.

However, I have been using the Augvape INTAKE RTA a lot recently and that tank NEVER leaks, runs on a single coil and produces some of the best flavors of any tank I have tested in the last 18 months.

The INTAKE RTA is your go-to if you’re new to RTAs and want something that doesn’t leak. It runs like a sub-ohm tank, which means simply, though you get much better flavor from it.

The flavor, the deck, the design. Everything is on point. For new users, the Augvape INTAKE RTA is 100% where it’s at right now.

Anything Else I Need To Know? 

Not really, we’ve pretty much covered everything you need to know about vape tanks – all of them!

If you’re brand new, I would say go with a standard, sub ohm tank to begin with. They’re just easier to live with.

Once you get that down, you can move onto rebuildable tanks, starting with RDAs – just make sure you get one that can squonk.

To recap, here are my current picks for each category:
