Rotkvapor Hkuda Intro

This review I am going to be taking a look at the Hkuda sub ohm tank from Rotkvapor. This is an interesting sub ohm tank and on face value it looks a bit like a subtank on steroids! The coils and RBA build deck are quite similar to the Youde Zephyrus. Let’s see if it performs just as well below.

Notable Remarks

Vaping the Hkuda at different wattages

Unfortunately I was only sent one 0.2Ω coil so I was only able to vape on this, results are below.

20w: Okay vapour production, no real flavour very cool vape
30w: Vapour production is okay, flavour starting to come through now
40w: More vapour production and flavour is better, a nice warm vape
45w: Getting slightly hotter now, still nice flavour and vapour
50w: Starting to get a little too hot for me now, flavour tastes a little burnt

Unfortunately although this tank looks like a subtank on steroids it doesn’t quite perform like one! This was a shame as I was really looking forward to this tank but it is a slight disappointment in performance.

I really like the design of this tank, it looks fantastic and the different colour O Rings really allows you to customise it! I’ve gone for red ones in mine at the moment but the blue also look great! I also like the airflow ring design, whilst it looks sharp and jagged which is cool it also makes it super easy to adjust the airflow by giving you some grip.

RBA Deck

I like the fact that Rotkvapor included an RBA deck with this tank! I wasn’t super impressed with the coils and so having the option to make my own and really turn this tank into a powerhouse is a great addition.

It’s really nice and easy to build on too which is a plus, if anything I think the Hkuda could quite easily be marketed as an RTA because of the standard of this RBA deck.

Top Fill

Although this is becoming standard on sub ohm tanks right now, top fill as a great feature and I’m glad Rotkvapor took the time to integrate it into the Hkuda. It makes filling a lot more convenient and it’s definitely a plus point in my books!


Stock Coils

The stock coil wasn’t fantastic; the wattages that it handled were a little low for the resistance in my opinion! I’d like to see a 0.2Ω coil handle up and above 60-70w comfortably and that just didn’t happen with the Hkuda.

Also the coils look messy and they lack quality, they are unevenly spaced, one coil had spacing and the other was completely squashed. It just looked awful! I by no means am an expert builder but I genuinely feel that I could make cleaner better looking coils! Rotkvapor you’ve got to up your game on the coils!


Whilst this tank looks the part and feels like it would be an absolute winner, it doesn’t quite live up to expectations. The coils are a bit shoddy and really impact on the tanks performance. I like the RBA deck and the styling of the tank. If you’re looking for a new RTA then maybe give this a go, but if you’re looking for a sub ohm tank I think there are better options out there. I think this tank needs a rebranding and to be marketed as an RTA, that’s where it shines!
