Geekvape Tsunami Mech Kit Review

The new Tsunami Mech Kit aims to improve on the Geekvape Karma Kit. We take an in-depth look here.


Geekvape Tsunami Mech Kit Intro

The very first review that I did for Vaping360 was the Geekvape Karma Kit, which included a beautifully machined copper Black Ring mech mod and a matching RDTA that converted to an RDA.

Today, we review the Tsunami Mech Kit that includes the new Black Ring Plus mechanical tube mod and the new Tsunami Pro RDA.

How does the new kit compare to the original? I will try and answer that.

The Tsunami Mech kit is available in two versions: copper, with resin sleeve and matching copper Tsunami Pro, or brass with black sleeve and matching black Tsunami Pro.

A quick search finds the kit on pre-order at a couple online vendors with a street price of $56.80US. Depending on where you look, retail is either 70 or 80 bucks – so if you want to feel like you are getting a better deal, buy from the site that claims the 80-dollar retail.

Notable Remarks

First impression


When I get something to review, I never get to choose the color or material of the item. In this case, I don’t know if I’ve got the copper version with resin sleeve (fingers crossed) or the brass/black combo. I open the box and see that my review sample is the brass version with black sleeve. Honestly, it’s purty, but I would have liked to see the resin version. Anyway…

The satin black mod sleeve matches the black finish on the Tsunami Pro nicely, and the mod has an almost elegant look. The RDA lines up perfectly with the mod when installed using the direct-to-battery cap on the mod.

The mod has a nice heft and hand feel with the satin finish and 25 diameter .

I pull the foam insert from the box and find the manual, spares, and the Geekvape T-tool for building the RDA. Love the T-tool.

Top cap options


The Tsunami Mech kit ships with two top caps: a direct-to-battery cap (installed) and a standard 510 cap with a spring-loaded center pin. Though I don’t intend on using it, I still want to at least test fit the 510 cap, and it gives me a reason to disassemble and inspect the Black Ring Plus.

To install the 510 cap, you must first remove the switch and sleeve from the mod tube. The switch threads are well machined and smooth — a dab of Noalox will make them buttery smooth and reduce wear and tear when replacing the battery. I remove the sleeve and find an o-ring about two-thirds up the body to help snug the sleeve and prevent rattle. Once removed, I find the top cap threads are even finer than those on the switch, and perfectly machined.

I install the 510 cap, sleeve and button to the solid brass body. The 510 cap pushes the weight of the Black Ring Plus from 168 to 180 grams, and the length increases from 91 to 96 millimeters.

A closer look inside


Looking inside the tube I find that, like the original Black Ring mod, the battery tube on the Plus has a plastic liner. This makes the mod safer to use if you reverse the battery, and/or have some nicks in your battery wrap. It’s a nice touch, but I would still insert the battery with the positive end up, and only use batteries with fully intact wrapping — good practice when using any tube mech.

Near the bottom Geekvape has drilled six battery vent holes in the sleeve, though only three are actually functional. The brass body blocks the other three, but this appears to be by design — no matter how you index the sleeve, you will always have at least three functional holes.

The button


The magnetic button is recessed, with no lock, and the action is extremely smooth with no crunch. The button also has a spring-loaded delrin ring that self-adjusts to prevent rattle, regardless of battery length

The Tsunami Pro RDA


Let’s not forget that this is also the debut of the new Tsunami Pro RDA.

The Pro is Geekvape’s latest version of the iconic Tsunami. It comes in at 25 mm and the 2.7 mm holes in Velocity-style posts are 10 mm apart, giving you a staggering amount of area for your coils.

Airflow is routed from the two slots in the deck to two 3.5 mm holes under each coil. The Pro cap is machined with three airflow slots to allow for a single coil option, and if you want to reduce airflow and chamber size to increase flavor, simply install the machined stainless steel 510 adapter and the drip tip of your choice.

Happily, I can report that the 510 pin on the Tsunami Pro protrudes a healthy 1.5 mm — more than adequate to use safely on the Black Ring Plus with the direct-to-battery connection.



I want to get a warm vape with a fast ramp, so I build the Pro with dual twisted wire coils at 0.23 ohm. I calculate that with my freshly charged Sony VTC4 I’ll get around 18 amps and 75 watts initially, though expect that to quickly taper off to around 60 watts as the battery drops to 3.7 volts.

At this point I give the mod a good shake, and detect a slight side-to-side movement of the battery. Much like the previous version of the Black Ring mod, the spring-loaded take-up ring does a pretty good job removing the top and bottom slack, but allows a bit of side-to-side movement. Not a lot, and it isn’t noticeable during normal use.

With the airflow wide open I take my first vape and it is exactly as expected: warm and dense, with good flavor. It compares very favorably to the CoilArt Mage Mech Tricker Kit I have on hand from a previous review.

Airflow is very good with the wide bore cap, similar to the Mage and a Kennedy I have on my bench. Even though this build is likely too hot for the 510 adapter, I try it with a short delrin drip tip. The vape is very warm with reduced airflow and the tip gets hot, but is tolerable. Still, I’m thinking a couple of single wire coils would work best with the 510 adapter.

I continue vaping and dripping, with no leaks, and the deep well (6.5 mm) held a generous 26 drops of juice from a glass dropper without spilling out of airflow holes.


  • Dual top cap option
  • Smooth fire button
  • Easy to build
  • Hits hard
  • Good airflow
  • Well-made/machined
  • Nice look and feel
  • Affordability


  • Minor battery rattle


The Tsunami Mech Kit keeps everything that works on the Karma Kit and improves on some of the concerns I had, specifically the short 510 pin on the RDTA when using the direct connection. It’s nice that Geekvape also includes the optional 510 cap for use with sub-ohm tanks, and to help instill confidence in new mech users, or anyone not comfortable with a direct connection.

This kit will appeal to seasoned mech mod users. It’s a well machined, hard-hitting combo with a great switch, good airflow and lots of room to build. With the lined tube and 510 cap, I can also confidently recommend it to anyone considering their first mechanical tube mod, and once they get comfortable it’s a simple operation to switch to the direct connection.

The Tsunami Mech Kit is further proof that Geekvape is committed to deliberate and thoughtful product design. Rather than bombarding us with poorly-tested, average products, they carefully and consistently bring us quality gear at affordable pricing. It’s a formula that has served them well for their short, but impressive three-year run and they stay the course with the new Tsunami Mech Kit.
