The Geekvape Tsunami Mech Kit has got the looks, but does it pack a punch? Find out in my review!

Today we are looking at the GeekVape Tsunami Mech Kit, a new addition to GeekVape’s arsenal of wallet friendly, yet quality made products.

Geekvape are a company based in china well known for their affordable vaping devices, atomisers and accessories.

They have previously released products such as the Ammit RTA, and the Medusa RDTA and the Karma Mech Kit.

The Geekvape Tsunami Mech Kit is currently available in a copper and resin finish, or a brass and black finish, but more interchangeable sleeves and drip tips should hopefully be coming soon. Today we will be looking at the copper and resin model.

As always my opinions are honest and my own.

*Mechanical Mod Safety Warning*

Please ensure that you have a firm understanding of Ohms Law and battery safety before using a mech mod before purchasing.

Thank you.

Build Quality & Design

The Tsunami 25 RDA:

So let’s start from the top! At the top of the Geekvape Tsunami Mech Kit. You have a large, wide bore resin drip tip.Geekvape Tsunami Mech Mod review

It’s large, but doesn’t feel awkward in the mouth. It is held into the top cap with a single o-ring.

Unfortunately mine is pretty loose, so it is a bit awkward if it get knocked as it falls off easily.

I tried two different o-rings included in the spares, and they haven’t fixed this.

Alternatively, you can use the 510 drip tip adaptor and use your own preferred 510 sized drip tip.

Below that, we have the beautiful copper Tsunami PRO 25 RDA.

The copper airflow barrel has “Tsunami” engraved into the side and has two different airflow options; single and dual coil mode. This is held onto the deck with two o-rings.

It has a large, gold plated deck with a dual post design. The posts are roughly 1cm apart and have surprisingly large post holes.

Big enough to put some beasty coils in if you wish! Your coil legs will be held in place with four flat head grub screws.

The juice wells are also quite deep, so if you’re prone to over dripping your RDA’s, this may save the odd leak or two.

On the base we have a gold plated 510 pin which protrudes a fair bit, so I am more than happy to use this on a hybrid mech.

The Black Ring Plus Mech:

At the top, we have a hybrid topcap, this doesn’t have a 510 pin, so please ensure that any RDA’s used with this topcap have a protruding 510 positive pin.

If you wish to use another atomiser that doesn’t have a protruding 510 pin, you can change the top cap for the floating 510 version that is included inside the box.

This is easily replaced, simply by dismantling the device and screwing the floating 510 top cap onto the tube.

The tube is also made from copper, but is wrapped in a beautiful marbled resin sleeve which can be removed by unscrewing the button and sliding it off.

It’s held in place by a single o-ring. This sleeve does move slightly up and down and is slightly difficult to grip when you have sweaty hands.

Inside the tube, there is a plastic insulator.

I believe this is there as a safety precaution, just in case the user has an unnoticed tear in the battery wrap which may cause a short and cause the battery to vent.18650 battery in Geekvape Tsunami Mech Mod

The button doesn’t have a locking function, but is slightly recessed into the base to avoid any accidental firing.

Inside are two magnets inside that repel each other, this is what gives the button its springy action.

And the action is super smooth. It doesn’t crunch or grind when pressing it, but it does require a bit of force to press it.

On the other side of the button, there is a spring loaded Delrin spacer which takes up any battery rattle inside the tube.Tsunami Mech Mod Button

Whilst giving the device a vigorous shake, I found the battery rattles slightly from side to side, but it isn’t noticeable with normal everyday use.

How Does the Geekvape Tsunami Mech Perform?

On this mech, I am using a 0.28Ω dual Clapton coil build with a fully charged Samsung 25R battery.

This is drawing roughly 15A and using about 63w of power. It has been wicked by Leo D Designs Texas Tuff cotton.

Ease Of Build On The Geekvape Tsunami PRO 25 RDA

The Tsunami RDA is extremely easy to build on.

As with most ‘Velocity Style’ decks, you have two holes on each post, and all are secured with flat head grub screws.

Slotting in the coils is an absolute breeze, just poke the legs through, clamp them down and cut off the legs.

I find that positioning the top of the coils with the top of the posts is the best for the coil build I was using. (Build in picture is different to one used in review)

Wicking the device is also easy as pie. Thread the cotton through and tuck down into the wells whilst avoiding getting any wick in the airflow chimneys.

Juice them up, and you’re ready to go!

Flavour & Cloud Production

With the build I am using, I was getting a nice warm and dense inhale, followed by an extremely cloudy exhale.

Closing the airflow down only restricted the airflow and didn’t effect the flavour or clouds to a noticeable extent.

Overall, I would say that this is more of a cloud chasing RDA rather than one that concentrates on flavour, even though the flavour and clouds are pretty good.

The flavour doesn’t blow you away, but it is very acceptable.

What I Like

The looks. WOW. This is a stunning looking mech. Simple, yet elegant. The plastic sleeve inside the mech. A great safety feature.

The inclusion of 510 adapters is good for those of you who like to chop and change.

The Tsunami Pro RDA is very easy to build on and depending on your build it offers great flavour and clouds.

What I Dislike

The drip tip on the mod I received was slightly loose as was the sleeve.

Final Review Verdict

The Geekvape Tsunami mech mod and Pro RDA is great when you get a decent build on it.

I had tried numerous builds on it around the 0.5Ω mark without much success. So moving down to the 0.28Ω dual Clapton build was an incredibly good move.

Obviously you could build lower, but this build suits me well.


  • Great looks
  • Good flavour & Clouds
  • Easy to build on
  • Two airflow options
  • Affordable


  • Loose resin components

Hi, my name is Dean and I have been vaping since April 2014. I decided to start reviewing back in mid 2015 as my friends kept asking me about different e-liquids I had tried and whether they were worth buying. So I thought I'd start on Instagram writing written reviews for them to read. Then several months later, I saw that people were publishing reviews on YouTube, so in late 2015 'TheDevilVaper' was born! And since then, I have built a following across social media and I'm reviewing anything from starter kits to mech mods. Budget e-liquids to premium flavours and prebuilt coils to carry cases. To me, vaping is more than just a way to quit smoking. It is now a hobby. And a hobby that I have great pleasure in doing! And if my reviews help people ditch the cigarettes, then it's a job well done. TheDevilVaper


  1. This mech mod is awesome because it’s affordable and works just like any other mech. It’s advantage is price and looks better than every over priced mech mods. It hits hard and looks nice. Since getting this, all my DNA mods are sitting on the he shelf. Mech just hits harder than my gx350. …… from now on, mech only.
