The Hellvape Fat Rabbit sub ohm tank is yet another collaboration with hugely popular US YouTube vape reviewer Billy, aka Heathen – he’s dropped the Vapin’ tag.
It has an hard act to follow given the success of the Dead Rabbit range of RDA’s and the RTA – and I shall be reviewing the new Dead Rabbit RDA V2 very soon.
I reviewed the original Dead Rabbit dripper and bloody loved it – I use the SQ RDA pretty much daily as a squonker and Simone gave the Dead Rabbit RTA a decent score.
BTW we might seem a little late to the party with this one – however I’ve heard the original release had a few minor issues ironed out in this batch.
Incidentally the name Dead Rabbits comes from a New York street-gang from back in the day – remember the film Gangs of New York?
What Can We Expect From the Hellvape Fat Rabbit Sub Ohm Tank?
Fat flavour and clouds bro!
At least that’s what I’m hoping for.
I’m also keen to look at the airflow on this one.
It features both top and bottom, both of which can be adjusted to suit your vaping style.
It goes without saying I’m hoping it’s leak proof and the coils whilst cloudy and flavoursome – also last a while.
OK enough preamble – lets see if indeed this one has made me a happy vaping bunny.
For the record this was sent to me free of charge for the purpose of this review – thank you – and as always my thoughts and opinions are unswayed by freebies.

It’s the top and bottom airflow that catches the eye on the Hellvape Fat Rabbit tank.
I can’t think of many – if any – sub ohm tanks with dual airflow – correct me in comments of the ones I’ve missed.
Both airflow slots are long but not very wide and are cyclops style and slightly angled downwards.
Each can be closed off letting you choose between top or bottom airflow and of course one or the other can be left open and adjusted.
As well as that, Hellvape says this airflow system adds a ‘cooling system’ which is a little strange given the coils included are rated at up to just 80w – more on that in a moment.
As for the coils, there’s x2 in the box – a single 0.2ohm mesh and the 0.15ohm quad OCC – and as to how they perform we shall of course be looking at in more detail in a wee while.
The name ‘Fat Rabbit’ gives the game away as to its size coming out at 25mm wide and 46mm from the base to drip tip.
There’s a choice of a 5ml stubby glass or the 2ml straight glass which as I’m sure regular sub ohm vapers know will mean lots and lots of refills whilst vaping.
Incidentally the low profile bubble glass adds around 3mm to the overall width coming out at 28mm.
Filling is as easy as it gets with two large fill ports underneath the top cap and there are x2 drip tips included with the antibacterial 810 added straight out of the box with a regular one added – there’s also 510 adaptor.
I understand the Hellvape Dead Rabbit sub ohm tank is also compatible with other coils including the Smok’s TFV8 Baby Beast coils – the Eleaf HW and the Aero from Geekvape – check around for others that may fit.
Design and Build Quality
As you can see from the photos, I received the stainless steel version and very clean and smart it looks too.
The body is made from good quality stainless steel and the machining is pretty much spot on – this is a solidly built piece of kit let’s put it that way.
All the moving parts unscrewed easily enough and even fresh out the box and dry, the airflow rings moved nicely with little if any scrunching.
There’s good resistance to them too, with barely any movement when set to your preferred setting, and the knurling whilst also looking good gives a great grip.
The straight glass at 2ml does make the tank look thinner – obviously lol – whilst the 5ml is low profile but does jut out somehow – I actually prefer it with the bubble glass and not just because of the constant need to keep refilling the smaller one.
Overall the Hellvape Fat Rabbit tank is a bloody good looker and the 2 logos etched into the small ‘cage’ look good too.
There’s a choice of colours: stainless steel – rainbow – gun metal – black and matte black with the latter looking very nice indeed.
So bad-ass design – good build quality so the zillion dollar question is how does it vape?

How Does the Hellvape Fat Rabbit Sub Ohm Tank Perform?
As we can see the tank comes with x2 coils so let’s see how each one performs. I shall touch on the airflow combos in a moment.
For the taste and vape test I ran through x2 fills of Papio from the Twelve Monkeys Origins range – a 65/35 PG/VG – a juice I know extremely well – and was using the bubble glass.
Fat Rabbit 0.15ohm Quad OCC Coil
Hellvape is calling this coil the H7-03 and it’s rated at 80w.
I primed this one hard given the size of it – there’s a lot of cotton in there.
I started at 70w with both airflow ports wide open – as I said, I’ll cover the airflow options shortly.
The vape was airy-ish and the flavour, whilst not as good as a rebuildable, was decent enough – a little on the cool side, but with good vapour production.
Shutting off the top airflow, and bumping the wattage up to the max of 80w, the vape was pleasantly warm with an obvious increase in vapour.
The flavour popped a little – but not enough to write home about.
Shutting off the top airflow and opening up the bottom fully, I found the flavour much better and touch of restriction – but not much!
I found a happy medium at 80w with the top airflow barely open and the bottom open fully – this gave me a warm and pretty decent flavoured vape and was my preferred setting using this coil.
Fat Rabbit Single Mesh Coil 0.2 Ohm
This is the Hellvape H7-02 and again rated at a max of 80w.
After once again priming this one and letting it sit for 10 minutes, I again began at 70w.
From the first puff I knew this was the better of the two coils with great flavour and denser vapour.
I bumped it up to 80w immediately and yup – the flavour really popped.
Not in the same league as some rebuildables, but a very flavoursome vape.
With both airflow ports wide open the flavour held its own, but came to life with the top a tiny bit open and the bottom fully closed.
That’s my preferred setting, obviously yours might be different and you do have plenty of options!
The Fat Rabbit Airflow
As you can see I managed to find my optimum setting and the beauty of this sub ohm tank is the amount of choices you have.
With both wide open and on a scale of 1:10 with 10 being the airest I’d give it an easy 8 maybe even a tad higher.
Top closed and bottom wide open it’s still an airy one at around 7 to 7.5.
Bottom closed and top wide open things get a little restricted at around 6 to 6.5 – a bit too tight for me.
So to recap – I found the top open slightly and the bottom wide open gave me the best flavoured vape – but hey it’s all down to personal taste.
I will say this is not the warmest of vapes – that’s I guess down to the ‘cooling system’.
I did bump both coils up to 90w and whilst things did obviously get warmer and the flavour upped a notch, I felt after half a dozen pulls the coil was struggling a little.
Both coils wicked very well indeed with not the slightest hint of a dry hit and I have had zero leaks.
- Good build quality
- Awesome design
- Choice of drip tips
- 510 adaptor
- Superb airflow options
- Choice of coils
- Full of flavour
- Great vapour
- Zero leaks
- Decent price
- Thirsty – this one drinks!
- 2ml tank needs filling every 15 minutes – thanks TPD!
- Not the ‘warmest’ of vapes
Final Review Verdict
As you can see my pros way outweighed the cons on the Hellvape Fat Rabbit sub-ohm tank – it’s a bloody good one.
It’s been a while since I used a stock coil tank and this one has impressed me for sure.
I absolutely love the design and it feels solidly made.
The quad coil is the weaker of the two IMHO with the mesh coil giving a pretty decent flavour.
It’s obviously not in the same league of some of the rebuildables out there, but for stock coils that mesh is really very good indeed.
The 2ml tank is a complete waste of time – with the need to fill literally every 15 minutes – you can thank the TPD limit for that.
Saying that the 5ml bubble glass is also a thirsty bugger – especially with the quad coil – but that is what it is I guess.
As to coil longevity – I’ve had both on the go for 10 days with little or no flavour drop yet – and I’ve used them both every afternoon.
Incidentally I have seen – in more than a few places I might add – this is merely a cash grab.
I have to disagree given not everyone uses or can use a rebuildable, if anything it was a natural next step.
Whilst I no longer use stock coil sub ohm tanks very much, if at all, I’ve really enjoyed using the Hell Vape Fat Rabbit sub-ohm tank and would highly recommend it.
So yeah, I am a happy vaping bunny
