Notable Remarks

Machining/Fit and Finish of the Tsunami RDA

Tsunami Taken Apart
Tsunami Taken Apart

The Tsunami RDA feels very well; I’m pretty confident they are using higher quality stainless steel than most Chinese manufacturers. It appears the quality control can be a little hit or miss though; mine came with rough threading on the 510 connector and minor scuff marks on the top cap. It’s not a huge deal as one can expect minor flaws from an RDA atomizer in this price range. Even though the threading isn’t pleasing to the eye, it threads onto mods without any issues and is actually smoother than expected. There was nothing functionally wrong with mine either, just a few minor visual defects.

I don’t want that to overshadow the quality though, this is definitely a well made piece. Everything fits together tightly and the brushed finish looks great. The deck o-rings were very tight from the start, but after applying some juice, the fit is much better. Overall, this feels more like a $70 atomizer than a $30 one.

Build Deck

The build deck is a velocity-style two-post deck that is very similar to the one found on the Griffin RTA. The posts are a little more spaced out and the post-holes are a bit larger on the Tsunami RDA to accommodate larger builds. With post-holes 3mm in length and 2.1mm in height and each lead having its own hole on a dual coil build, this atomizer will satisfy just about any builder out there.

Ease of Build

Building the Tsunami is as simple as one would expect from a velocity-style deck. Each lead has its own post-hole on a dual coil build, requiring less bending to mount the coils. Since the airflow holes are located in the center of the deck, the coils don’t need to be positioned out to the edges like it would have to on a side airflow atomizer; this gives you a little more room to fit larger coils.

Juice well

The juice well is about 6.5mm deep and I was able to fit 19 drops of max VG in it with a dry wick. If you’re not careful when dripping, some juice can run down into the airflow pipes causing it to leak. However, if you pull the top cap off and paint the coils, you will have no issue. I did find dripping into the drip tip to be reliable as long as you stick to around ten drops every five or six pulls to avoid leaking.

Airflow and Controller of the Tsunami RDA by Geek-Vape

The airflow slots measure 3.5mm x 7.9mm and lead into a set of 4mm airholes. The air enters an area of roughly *28.5 mm² and transitions to an area of roughly *25.1 mm² before entering the chamber, causing an increase in airflow velocity. This is a concept seen on several other RDAs such as the Snapdragon, Sub Zero and the AX1 and has proven to have a positive effect on flavor output.

The airflow can be adjusted by turning the top cap and closing off the airflow slots. There is also a single coil airflow option which is a nice addition to an already familiar design.

The draw is just a hair tighter than the Aeolus Lite wide open and a hair looser than the Aeolus Lite with two of the larger air holes open. It does feel different though due to the nature of the way air flows inside a chamber with bottom air flow versus top airflow.

I really like the clean design of the Tsunami RDA. The engraved Tsunami logo looks well done and I love how it’s only noticeable when the top cap is off; there’s branding, but Geek-Vape is not shouting it. The brushed finish also looks nice but in the end, this atomizer looks a lot like the Kennedy 22 without the Kennedy logo which isn’t necessarily a bad thing.


The first thing that comes to mind when vaping the GeekVape Tsunami is “Wow, this vapes just like a Kennedy!”. It has the same buttery smooth, open but not ridiculously airy draw. I’m not a big fan of airy draws; I assumed I was going to be closing this off quite a bit to satisfy my tastes, but there’s something really nice about vaping this wide open. The flavor is very good and does not get any better when closing off the airflow, it just gets warmer and denser. I really like that the airflow controls the heat and density of the vapor, not the flavor; this allows you to really dial in the vape you want without sacrificing flavor at all. The vapor production is also excellent; wide open, it will put out larger, thinner clouds and closed down, it will put out smaller but denser clouds.

This atomizer appears to cater to the flavor chasers and the cloud chasers and it does both very well. I would say the flavor is just a touch better than the Aeolus line of RDAs which is no small feat!


  • Extremely smooth draw
  • Great flavor and vapor production
  • Higher quality materials used
  • Velocity-style deck makes building a breeze
  • Huge post-holes allow creative freedom with exotic wire
  • Added adjustable air flow to an already well-received design.
  • Single coil option
  • Deep well holds plenty of juice
  • Nice selection of included drip tips


  • Requires controlled dripping in order to prevent leaks
  • May have minor defects

Verdict of the Tsunami RDA

The Tsunami RDA by Geek Vape is likely to become one of the hottest RDAs on the market due to its improvements over the incredibly popular Kennedy RDA. The flavor is great, the vapor production is fantastic, the draw is incredibly smooth, the deck is very easy to build on and the adjustable airflow control is a huge plus. With the release of the Tsunami RDA by Geek-Vape, I can no longer see a reason to buy a Kennedy unless you really want the 24mm option; the machining is certainly not 3x better on the Kennedy and the performance is nearly identical. If you were looking into getting any of the Kennedys, definitely check this out first; if you don’t know much about the Kennedys and are looking for an RDA that has an easy yet versatile build deck with large amounts of vapor production and great flavor, this is the atty for you.

*Measurements were taken of a single air intake (single coil airflow), for dual coil measurements, just double the measurements
