This time, I have the latest chubby bunny to take a look at – the Hellvape Fat Rabbit 2 RTA.

Well, it looks like the designers over at Hellvape have been over-feeding their Bunny Rabbits again!

Being the 4th tank to bear the moniker of Fat Rabbit, it’s another great example of Hellvape’s ingenious design and craftsmanship which they put into all their products!

The original Fat Rabbit RTA took enthusiasts of the brand by storm, so how did I get on with this new version?

Hellvape is a company that has been around the vape scene since 2016. They have their main offices and manufacturing plants based in China. Hellvape also has sales outlets worldwide. No other introduction is necessary to the vaping community because of the sheer popularity of their products!

They are known most famously for their Dead Rabbit range of RDA and RTAs.

The Fat Rabbit range includes the Fat Rabbit RTAFat Rabbit Solo RTA and Fat Rabbit 2 Sub Ohm Tank.

What to Expect From The Hellvape Fat Rabbit 2 RTA?

Hellvape has released this Chubby Bunny 2 RTA in 6 colours – Black, Rainbow, SS, Gold, Gunmetal and Blue.

Essentially the Fat Rabbit 2 RTA is an upgraded version of the original Fat Rabbit RTA!

It has a postless build deck that provides ample space for dual coil builds!

Hellvape has upgraded the internal airflow to a honeycombed style that helps to increase the flavour profile by 15%, controlled by its top and bottom dual airflow.

This RTA has a substantial 4ml liquid capacity that can be increased further to 6.5ml by changing to the Bubble Glass. There is a 2ml version for release in TPD regulated areas.

The ¼ turn fill top cap makes this a very easy-to-fill tank.

The Fat Rabbit 2 RTA was sent directly to me for review by Hellvape!

As always my thoughts and views are my own, after considerable testing.

Hellvape Fat Rabbit 2 RTA – Design and Build Quality

I have the standard Gunmetal version of this Rebuildable Tank Atomizer, it comes well presented in a card box.

The kit includes a host of extras under the foam tray (coils, cotton, screws, O-rings and screwdriver).

Like always with Hellvape products, this one has a great quality of manufacture and a design that is excellent!

The construction materials of the Fat Rabbit 2 RTA include 304 Stainless Steel, Pyrex glass and Delrin.

This RTA is dismantled into 7 parts – this includes the top and bottom airflow rings, the latter of which I have not yet been able to remove lol.

Starting At The Top

Gracing the top of the Fat Rabbit 2 RTA is a Black Delrin 810 mouthpiece.

A removable ¼ turn fill cap makes filling this tank easy and less messy. The cap has an embedded O-ring to stabilize the mouthpiece.

Around the edge of the cap is a knurling band that helps with its removal.

On the reverse side of the cap, you will see an O-ring that helps with leak prevention.

Filling this RTA is very easy via the 2 kidney-shaped slots.

The top airflow ring is removable from the main structure, which also houses the chimney and the coil cover.

On the outside of the coil cover, it has been engraved with the Fat Rabbit Logo.

The inside of the coil cover has 2 plates, each having 12x Ø1.2mm honeycombed holes – these connect with the top airflow and allow air to strike the coils.

The Fat Rabbit 2 RTA comes with the 4ml straight Pyrex glass installed.

NB – the standard version of this kit has a 6.5ml bubble glass in the box, whereas the TPD version comes with a 2ml glass.

When removing the build deck/base from the tank, the tank glass is then removable.

Hellvape Fat Rabbit 2 RTA – Build Deck

After removing the build deck from the tank, you will see 32x Ø1 airflow holes, 24 of which are enclosed within a Peek insulator surround, along with the positive wire slots.

To each side of the wire slots are two spaces for your wick tails and directly under the deck you will see a well-turned thread for the coil cover.

On inspection of the build deck, you will note it is raised slightly from the base so the air will flow freely beneath the coil.

Bottom Of The RTA

Hellvape has printed the normal legal logos, their logo and the name of the RTA.

The well-turned 510 connection threading holds a Gold-plated pin.

Airflow

Like the original, this version of the RTA has dual airflow rings, allowing the user to dial the airflow to suit their taste!

Both airflow rings have a lined pattern for decoration that also helps with grip while turning either airflow.

Hellvape Fat Rabbit 2 RTA – Quick Start Guide

Due to my nickel allergy, I will be using KA1 24g, two strands separately twisted, 7 wrap DIY coils. These were made on a 3mm post and spaced – both together = 0.12 Ω.

I will be using this RTA on my Smok Mag 18 Mod, and my choice of liquid today is Cider “Rhubarb” by E Juice Warehouse – it’s a sharp delicate almost floral flavour.

Hellvape Fat Rabbit 2 RTA – Prepping the Deck

Use the Ni80 coils that came with the kit or like me make your own DIY coils!

  • Remove the base/build deck and install your coils – BTW I cut my coil tails at 5mm using my Coily Tool, the kit does include a cutting tool
  • Heat and scrape your coils, so they glow from the inside out unless you have spaced them like mine
  • Insert the cotton through the coils cut and fluff and tuck the cotton tails into the cotton spaces
  • Dampen your cotton and coils with E-liquid – this is called Priming your coils
  • Reassemble the RTA and fill the tank with e-liquid
  • Screw the Fat Rabbit 2 RTA onto a suitable device and leave the mod and tank alone for around 3 minutes so the cotton can soak up more liquid!

How Does the Hellvape Fat Rabbit 2 RTA Perform?

I prefer to use RDAs and RTAs as I find them more satisfying with better flavour and vapour production. It’s also cheaper and easier to create my coils!

Wattage

I started using the Fat Rabbit 2 RTA at 30W for a few toots just to bed the coil in. With both airflows set to their lowest setting, I did enjoy a loose MTL draw!

There is no getting away from it F.R 2 RTA is most definitely a cloud-chucking DTL beast.

I took my wattage up to 50, 60 and then to 70W, all of which gave me an adequate warm vape with a heck of a cloud.

I upped the wattage to 100W and 150W and almost barfed up a lung, as the vapour was too hot for my micro lungs!

My standard everyday wattage for this RTA is between 75 and 90W with the airflow rings set almost open.

Flavour

I like to think of myself as a fruit flavour connoisseur lol – I am constantly searching for great fruit-flavoured e-liquids.

Of course, to get a great flavour from your liquid, you will need a good RDA/RTA and thankfully, the Fat Rabbit 2 RTA not only fits the bill but delivers some of the best flavours I have enjoyed for a while!

Airflow

Very much like the original chubby bunny, I found the Fat Rabbit 2 RTA dual airflow was delightful to use. I was able to dial both airflow rings to suit my style!

I put the F.R.2 RTA up against the original Fat Rabbit and agree with Hellvape when they say that the honeycombed airflow increases the flavour profile by 15%.

The draw for me was very smooth, with a full-on flavour and excellent vapour production, no matter how I set up the airflow!

My Tests

The F.R 2 RTA handles chain vaping well! However, I have found the tank does become very hot quickly especially if you chain vape it with a high wattage. As it is made primarily of Stainless Steel, it fortunately cools off fairly quickly!

In testing, I have also used the Fat Rabbit 2 RTA with a couple of my other mods, the Geekvape L200 Classic and the Aspire Rhea both of which look great with the 28mm Fat Rabbit 2 RTA on top and function is top-notch with it.

Pros

  • Great quality and design
  • Good flavour
  • Wonderful vapour production
  • Delightful airflow control

Cons

I have no concerns with this RTA at all.

Final Review Verdict

A great-looking addition to the Hellvape range of Bunnies, it functions exactly as it is described in the promotional material!

This RTA was created for intermediate to experienced vapers – I wouldn’t recommend it to those of lesser experience.

I didn’t find any peculiarities with this RTA and I would’ve bought it anyway just to add to my collection!

Hi my name is Kevin, I started vaping back in 2009 mainly because my little boy at 3 years old was starting to copy the way daddy smoked a cigarette! Over the years I have gained a good amount of experience with different types of vaping hardware but I'm just a normal guy who enjoys sharing my experiences. This is why I started my Youtube vape review channel in 2014. To date the channel has had over 500,000 views. Being disabled, vaping has given me a gateway to meeting people from all different walks of life, many of those I would not have met under other circumstances. The way I look at my reviews is, if I can convince just one person to give up the stinky’s my job is done. I class myself as a tinkerer as I like to take things apart to see how they work and put them back together, yes that includes e-cigarette mods! One day I would like to be able to design my own mod. I am a dedicated father, and husband to my sweetheart of nearly 30 years! Family to me comes before anything else.
