What is an RDTA?

One of the things that can make vaping pretty confusing when you are starting out is all the different names for the devices. RDA’s, RTA’s and more recently RDTA’s have been building in popularity. Do rebuildable dripping tank atomizers really give you the “best of both worlds?”

Think of an RDTA atomizer as a cross between a tank and an a dripper. Instead of only holding juice within the cotton and juice wells, it’s essentially a dripper sitting on top of a reservoir of e-juice. The wicks hang down into the tank and feed the juice to the coil as you are vaping.

RDTA’s are based off the genesis style of atomizers which were popular for their flavor. Traditionally stainless steel mesh was used for wicking, but since has been replaced primarily with organic cotton. RDTA’s are a throwback, but at the same time, they are also cutting edge.

Another advantage of using RDTA’s is that they are often times easy to fill, despite not holding a ton of liquid. Instead of unscrewing it apart like a tank, most rebuildable dripping tank atomizers pop open like a dripper (by pulling off the top cap) so that you can fill it up or use it as an RDA.

Let’s take a look at some of the best RDTA atomizers available on the market today…

    The problem with RTA's

    Many rebuildable tank atomizers, aka RTA’s are great, but you’ll never get the same experience on one versus that of a dripper because of the few extra millimeters that the vapor has to travel through the chimney. This can make a world of difference, believe it or not. Hence the RDTA…

    Let’s rewind a few years back to when you could only get this type of performance from a vape tank. Since then, some impressive RTA’s have come out, but are still outshined by most RDA’s. For years, vapers have strived to attain that seemingly impossible “dripper in a tank” experience.

    Rebuildable dripping tank atomizers were the industry’s answer to this desire. On an RDTA, the mouthpiece sits right on top of the coils, just like an RDA. Unlike a tank, the vapor doesn’t travel through a chimney, it’s the same proximity to your mouth as it would be on an average dripper.

    The Genny lean?

    Many RDTA users have found themselves doing this, and no it isn’t a new hip-hop dance craze. The Genny lean, is tilting your RDTA on an angle when puffing on it, to ensure that the cotton gets saturated, especially when your tank is running low. Back when Genesis atomizers were more popular, this was a common tactic used to combat those dry hits you would otherwise get.

    5 Tips for building/wicking RDTA's:

    1. Comb and fluff your wicks before vaping
    2. Don’t be cheap, use a good amount of cotton
    3. Don’t use too much cotton or dry hit city
    4. Experiment with where you like to cut your wicks
    5. Don’t build your coils too high or too low

    Even the best RDTA tanks require some trial and error to attain the perfect build and wicking. Experiment with different builds and techniques to find out which one is best for you.


    Now that you have seen some of the best RDTA vapes and have a basic understanding of how they work, we want to know what you think. Do rebuildable dripping tank atomizers really give you the “best of both” worlds? Technically speaking, they do.
