It is a stylish looking bit of kit that aims to offer premium performance at a very wallet friendly price.

Design and Build Quality

With its grooves and clean lines, the Geek Vape Karma is a very nice looking piece of kit.

The black Karma RDTA/RDA and the copper Black Ring mechanical mod contrast really well together, and with its 25mm width this feels nice and weighty too.geek vape karma mechanical mod review

The switch at the base has the Geek Vape logo etched onto it, and looks pretty cool.geek vape karma fire button

The switch can actually be twisted off easily which allows you to insert a single 18650 battery- you’ll see that the battery compartment is actually Delrin insulated inside.

This gives an extra layer of protection against short circuits, especially if you have mistakenly used a battery with a torn wrap.geek vape karma insulation

There are also vent holes drilled around the base of the Black Ring.

At the top of the Black Ring mechanical mod is a direct to 510 hybrid connection. This means your atomiser essentially connects directly to the battery and allows for maximum conductivity, this can also be dangerous too.

You need to make sure the 510 pin on your atomiser is protruding at least 1mm, to prevent hard shorts, and never use a sub ohm tank with a fixed 510 pin.

Also ensure that your chosen 18650 battery has no tears on the wrapper, and make sure you have an understanding of Ohms Law so that you know whether your battery is capable of handling the amp draw from your build!

Out of the box the Karma RDTA / RDA has the 510 pin set in the correct position, so you should not need to adjust this.

The Karma is a pretty cool little RDTA/RDA.

Out of the box it is set up in RDTA format, which means you have a 5ml capacity.geek vape karma rdta

Three airflow holes are on either side and these can be adjusted by rotating the top cap, however you cannot close a single side off to just use a single coil.geek vape karma airflow

There is a 2 post Velocity style build deck present, with large post holes making building easy.geek vape karma rdtaFilling is done easily by revealing the fill holes on the side.How to fill the geek vape karma rdta

Karma RDA

You can transform the Karma into an RDA pretty easily, simply unscrew the central post underneath the build deck, remove the glass tank section and screw the deck back into the base before replacing the top cap. You’ll then be able to use the Karma as an RDA.geek vape karma rda

There’s a large 2ml juice well in RDA mode, and the large chuff cap on the top cap makes it easier to inhale huge clouds!

How Does The Geek Vape Karma Kit Perform?

One of the key things that people look at when purchasing a mechanical mod is how hard it hits.

With the smooth threading, hybrid connection and magnetic battery cap, the Geek Vape Karma Kit hits very hard indeed!geek vape karma mech mod

As long as you keep the threads and contacts clean, I’d advise cleaning it once a week at least, the Geek Vape Karma Kit will continue to hit very hard.

It does feel like you are getting the full force of the battery when you use it, it’s definitely not one for the faint of heart!


The Geek Vape Karma atomiser didn’t seem to offer very much in the flavour department with an e-liqui I know well, ZAP! Juice Melonade.

I tried various builds in RDA and RDTA mode, and couldn’t get anything special out of it.

That’s not to say it’s bad, but it just doesn’t offer a whole lot of flavour.

It does however offer a lot of airflow, and plenty of vapour, so if you like your clouds then I’m sure you will be pretty impressed with the Karma.

I was producing room filling clouds with ease!

One of the key selling points around the Karma kit is not only do you get a well crafted copper hybrid mechanical mod, but the Karma can be switched from an RDA to an RDTA.geek vape karma RDA and RDTA

It still seems to perform the same in my opinion, switching between the two didn’t alter the performance, but it is good to have the option there.

What I Liked

The looks and build quality. I really do feel that this is a great looking piece of kit, that despite the price is very well made, and it just feels really great in hand.

The switch is excellent. It’s really smooth, with a fairly long throw, and it feels very satisfying to press!

The option to switch between RDTA and RDA is great. You can have it in RDA mode for dripping at home, and still have a 2ml capacity, when out and about you can quickly switch it to an RDTA and take advantage of the 5ml capacity.

The price is superb for a mod and atomiser combo. I’ve seen some Far Eastern sites offering the Karma Kit for under $30 delivered, which is an insanely good price!

What I Didn’t Like

You need to give the Geek Vape Karma kit a thoroughly good cleaning upon arrival, as mine was smothered in machine oil!

I didn’t feel that the Karma atomiser offered anything special flavour wise. It’s a shame as it’s great for cloud chasing, and Geek Vape are known for making some great flavour atomisers!

I would have liked a single coil option on the Karma atomiser. You can only set this up in dual coil, and I do prefer setting atomisers up with a single coil if I am using them with a mech mod.

Final Thoughts

I can’t help but be impressed with the Geek Vape Karma Kit.

For a very small initial outlay you have an RDTA/RDA plus hybrid mechanical mod combo, that can be set up easily and does offer good performance. Especially excelling at cloud chasing.

The build quality is really good for what you pay, and it is a very smart looking combination too!

The Good

  • Beautiful looking set up
  • Karma RDTA/RDA is capable of some serious clouds
  • Easy to switch between RDTA and RDA mode
  • Good capacity in both RDTA and RDA mode
  • Easy to build on
  • Spare glass included
  • Hits very hard indeed
  • Very smooth switch
  • Threading is very good
  • Treated copper slows down patina
  • Very competitive price

The Not So Good

  • Copper finish on the Black Ring picks up dirt easily, tarnishing the look
  • Karma RDTA/RDA doesn’t offer anything particularly special in the flavour department
  • Machine oil present upon arrival
  • Hybrid mechanical mod- not for beginners, can be dangerous in the wrong hands
  • Need to adjust contacts first otherwise you get battery rattle
  • Dual coil only with the Karma RDTA/RDA

Likelihood Of Replacing If Lost Or Damaged
Been vaping full time for three and a half years, started on cigalikes for a fair while then curiosity got the better of me and I moved onto an ego/ce5 set up after, a month or two later I was seeing people walking around with these interesting shiny tubes and I thought 'I gotta get one of those'. Before I knew it a trip down to my local B&M got me my first VW mod, an Innokin SVD, paired with an iClear 30, and I was hooked. Soon after that I was jumping to VW mods both box and tube shaped, before I then made the jump to rebuilding and thus sub ohming, with my first RDA and mech mod. These days I'm still preferring mechanical mods, but using VW mods with both RDA's and tanks alike whilst on the move, most importantly I am still loving vaping!


    • Hey Saltox.

      No such thing as the best coil or best build, as it’s all subjective due to vaping style, but with using mechs you want a wire with a fast ramp up time, I only use Nichrome or SS316L wire with mechs (and I use mechs 95% of the time these days).

      I aim to build in the 0.25-0.4ohm range as I get flavour and vapour in abundance 🙂
