Joyetech Cubis Review

Joyetech Cubis Intro

By several professional reviewers (and by Joyetech), the Cubis Tank has been referred to as “innovative” and “leak-free”. One video-review in particular totally sold me on this tank, so I had no hesitation with buying it!

But is this innovation amounting to better performance than what we are accustomed to?? Is the Joyetech Cubis going to make your eliquid shine, just because it is leak-free and innovative?

Here’s a quick look into my experience with the performance of the Cubis tank by Joyetech. This is not a ‘full’ review of the ins and outs of the tank, it’s merely about how it performed when I used it. This will be short and sweet.

  • Very competitively priced! But is it really competing with the Cleito? Don’t think so!
  • Comes with three coil heads of separate resistances
  • Can use the SS coils in temp or power mode (as long as your mod is set up for SS)
  • Easy as hell to fill due to it’s top-fill, “innovative cup design” (literally, you just pour liquid in as you would a cup!”)
  • Very creative design that is really unlike any other tank we’ve seen
  • Truly is leak-free
  • Very nicely manufactured
  • Caged glass tank to protect the glass
  • 2 separate drip tips (I really like the clear, plastic one)
  • Integrated and hidden airflow control that is easy to adjust
  • Very unique coil heads with an interesting airflow design (but I honestly can figure it out)


  • Difficult to know where you have your airflow set
  • Spitty coils
  • Hardly any flavor from the Clapton coils and the others are mediocre at best

Performance Remarks

Joyetech Cubis SS316 0.5, SS316 1.0 and the Clapton 1.5 Ohm Coil
Joyetech Cubis SS316 0.5, SS316 1.0 and the Clapton 1.5 Ohm Coil

I tried all three coils within their recommended ranges and I tried the SS 316 coils in various ranges and temps in TC mode (on a RX200 and an SX Mini ML-Class). At their max power or temp, none of the coils in my experience produce flavor that is noteworthy enough to make me want to vape it beyond the purposes of this review.

The 0.5Ω coil performed all around the best for flavor, but, ultimately, even it was an anemic vape for flavor though it puts out decent vapor. They do include a Clapton coil, but it is a really high resistance for a Clapton (1.5Ω) and it was the absolute worst performer for flavor and vapor – though that one is meant to be more of a mouth-to-lung vape (but even for that, I don’t think it performed well at all—and I do love a good mouth-to-lung vape).

I’ve tried and tried with this tank. I keep thinking that the next attempt will finally reveal some worthwhile flavor, but it hasn’t. As it stands now, this tank is one of the coolest little tanks I have that will never again sit on any of my mods.


I only paid about $20 for this tank, so it’s not a huge loss.  But then again, I don’t think I could ever lose a $20 bill and not want it back.  When I was vaping on the Cubis tank by Joyetech, it felt like I lost a $20 bill . . . so yeah, I wish I could have my money back.

The two best parts of the Cubis is that it TRULY is leak-free and it does reshape what we think a ‘normal’ clearo should be designed like—and I believe this type of design can eventually perform amazingly—but for me, the flavor is just too lackluster to give it anything more than points for being ‘cool’ and leak-free.

For a tank in this price range, we recommend the Cleito by Aspire.

Must be missing something. have nothing but positive things to say about the tank.Tried one and liked well enough to buy a second one tank is inexpensive and well worth it.

I just got a Cubis in this week and started using it with the 1.5-ohm Clapton. The experience reminds of vaping in 2013. Hopefully the other coils will be better. I’ve heard from a few people that the coils are wildly inconsistent. It’s a shame since I dig the clean looks and leak-proof design of the Cubis.

I had pretty high hopes for this as well. Will there be a follow up review when the Ni and Ti coils come out?

I’m using this one now for several months and in the beginning it was great and taste was awesome. I vape it with the Clapton coil at 15 Watts, any higher it produces quite quickly a burnt aftertaste. But my main problem is a constantly flooding coil, no matter what I try (new coil, thicker/thinner juice, loosening the top, adjusting air flow). It’s becoming very annoying now and I just sent Joyetech an email about it. Meanwhile, I see no other option than to vape my other tanks. Really crap because the Cubis does give the best taste out of… Read more »

Cover mouthpiece with paper towel Hold the tank and flick wrist down hard few times juice will come out the mouthpiece usually works or other tanks need to be blown through the mouthpiece while holding upside down juice’ll come out airflow

My first ever tank is a Aspire Nautilus Mini and my second is the BeyondVape Silo Beast. Both these tanks I’m using with a SXmini on TC Ni200. Expensive mod but worth every penny.
The Cubis should has been a nice “in between” tank.

Yes, MTL is my favorite way of vaping. Despite the Nautilus Mini is a near perfect tank, I find the maximum draw a little bit on the tight side. Besides that, I have absolutely no issues with it. Great little tank to start with and use it forever if you like it. The Beast I use when I want to tease non-vapers a bit. DL gives me pleasure with really soft & mildly sweetened juices. Like Advocate with a big topping of whipped cream, or Hot Chocolate (with cream). I make my own juices almost from day one, use only… Read more »

The airflow of the coil is almost none, heck the old subtank coils have 5x the airflow. I think a redesigned coil alone with openings much larger for juice would 100% make it a go to tank. But from an engineering standpoint, it’s just a guess if it’s possible. Might be a great mouth to lung low vg mostly tobacco quit smoking juices at low wattage, but for vaping, it’s time for Version 2.
