In this review, we are looking at another over-fed bunny from Hellvape! Say hello to the new Hellvape Fat Rabbit Solo 2 RTA – which is an updated version of the Fat Rabbit 2 RTA!

This RTA is another great example of Hellvape’s craftsmanship and marks their breeding résumé with excellence for ingenious design and manufacture!

As a company, Hellvape doesn’t need a long introduction mainly because of their standing within the vape community, along with the sheer quality of their products speaks for themselves!

Hellvape have been around the vape scene since 2016, their main offices and production plants are based in China.

The popularity of the company started to climb in 2017, with the invent of their Dead Rabbit series of RDA and RTAs, their Fat Rabbit series of tanks are proving to be almost as popular!

What to Expect From the Hellvape Fat Rabbit Solo 2 RTA?

This RTA has been released with 7 colours options – Full Matt Black, Matt Black, Gunmetal, SS, Blue, Gold, and Rainbow.

As normal, Hellvape have produced two versions of this RTA – a 2ml version for the TPD market and a 3ml standard version with a spare 5ml bubble glass.

The Hellvape Fat Rabbit Solo 2 RTA has 3 available airflow combinations:-

• Top
• Bottom
• Both together

Trust me – this RTA can produce a “Hell” of a lot of vapour with great flavour!

With a base diameter of 25mm, the F.R.S2 will be at home on even the most popular of devices!

While the name suggests a single coil RTA, its postless deck will support single and dual DIY coils!

My sample of the Fat Rabbit Solo 2 RTA is the standard version and was sent directly from Hellvape for review!

Any thoughts and views expressed are my own, after a considerable testing period.

Hellvape Fat Rabbit Solo 2 RTA – Design & Build Quality

I was sent 2 samples of this standard kit, Full Matt Black and Gold!

Both kits came presented in card boxes, and as always Hellvape included extras – a flat-head screwdriver, post screws and O-rings.

Also within the kits are – 1 pre-made 3.5mm Ni80 coil, a coil cutting tool and 1 strip of shoelace cotton.

This RTA is constructed of 304 Stainless Steel, Pyrex glass and a Resin mouthpiece.

Hellvape says the Fat Rabbit Solo 2 RTA has 7 parts when dismantled. To date, I cannot remove the bottom airflow ring on either tank!

As always Hellvape’s standard of quality design and manufacture is outstanding!

Starting at the top

This RTA has a removable 810 Resin mouthpiece, in various colours depending on the colour of your tank!

The top of the cap has a thick O-ring to stabilize the mouthpiece. The cap is removed from the main body with a ¼ turn.

On the reverse of the cap, you will see an O-ring which helps to minimise leaking.

The top airflow adjustment ring is removable for easy cleaning and has a lined decoration to help turn the ring while in place!

Middle Section

This section is all one piece and is lightly embossed on the outside of the coil cover with the Fat Rabbit logo.

Two kidney-shaped fill ports are housed in this section along with the dual top external airflow that consists of two slots that angle inwards!

The centre hole you can see between the two fill ports is the chimney exhaust which is where you get the lovely vapour travelling to your lips!

Looking inside of the coil cover you will see 2 honeycomb airflow plates each consisting 16x 1.2mm holes.

Build Deck

When the build deck is unscrewed and removed, you will be able to easily change the Pyrex glass tank!

Hellvape have given us a simple postless build deck that has plenty of room to hold a single coil of up to 4mm or dual coils of 2.5mm inner diameter!

The deck has 4 screws to capture your wire tails. The positive wire slots sit inside a peek insulator and seated between the wire slots is the internal deck airflow which comprises of 20x 1.1mm holes.

To each side of the deck is a space to tuck your cotton tails!

The deck has a threaded ring, which allows a smooth connection to the main part of the tank and an O-ring for the Pyrex glass to sit on!

510 connection base

Looking around the base; the bottom airflow ring has a turn decoration which is similar to the pattern of the top airflow ring. I have not yet been able to remove this airflow ring without damaging the RTA base!

On the bottom of the base is printed the normal safety information. It also has a 510 post which has well-turned threading and a gold-plated connection pin.

Hellvape Fat Rabbit Solo 2 RTA Quick Start Guide

Today I will be using the Fat Rabbit Solo 2 RTA on my Innokin Coolfire Z60

Due to my Nickel allergy, I will be using a homemade single 6-wrap Kanthal 20gauge coil made on a 4mm rod for this review!

The liquid I will be using for this example is called “El Azul” from “Over the Border”.

My wicking material is Cotton Bacon V2. I’ve also swapped the 3ml Pyrex glass for the 5ml bubble glass!

Basic Prep Guide

• Install the coil then heat and scrape it, to get rid of any hot spots
• Add your cotton through the coil, and tuck the ends into the build deck

Make sure to tuck the cotton behind the threaded ring, or you will find the cotton will catch once the main tank is replaced.

Tip: Don’t overstuff the cotton into the wick spaces or you might get a liquid lock!

• Dampen your coil and cotton with e-liquid this is known as Priming your coil
• Re-assemble the build deck back into the main tank. At this point, I like to close both airflow slots. I often find this helps to eliminate air bubbles and leaks via the bottom airflow
• Unscrew the top cap and fill the tank with e-liquid

Screw the tank onto a suitable device, open both airflows to your desired level, and now enjoy a great-tasting cloudy vape!

How Does the Hellvape Fat Rabbit Solo 2 RTA Perform?

I’ve said in the past I love using RDA’s and RTA’s. Being the skinflint I am “lol” I find it cheaper to use this type of atomiser rather than the stock coil variety!

I am impressed with the new Fat Rabbit Solo 2 RTA. While it has the standard Hellvape look it is very much in my wheelhouse, it is simple to build on and being simple for me is always good “lol”. The tank fills quickly and is easy to dismantle for cleaning!

My 6 wraps coil has a resistance of 0.3Ω and I cut its tails to 5mm using my Coilytool.

Hellvape Fat Rabbit Solo 2 RTA In use

I bedded the coil in, with both airflows opened to less than a quarter and my mod set at 20W for a few MTL toots.

With both airflows open to about 1/2 I upped the wattage to 30W. I was able to enjoy a good approximation of a Restricted Direct to Lung style, which produced a hell of a good flavour!

Upping the wattage to first 35 then 40W after opening both airflows fully, using the DTL style of vaping, I enjoyed a flavourful and cloudy vape.

I did try a 50 and 60W vape with this coil but found that while the vapour production was still great the flavour dropped off considerably!

Dual coil use

I know you’re going to ask, did I plug in dual coils? Yes I did I used two Kanthal 24g, 2.5mm diameter coils in my gold version of this RTA they totalled 0.39Ω with 9 wraps each.

I treated them as above for the single coil and managed to take the wattage up to 50W before I detected a drop in the flavour of my T.Juice Red Astaire!

Hellvape Fat Rabbit Solo 2 RTA Airflow

While not a completely silent airflow I have no complaints with it, it was smooth on whatever setting I had it on.

The Fat Rabbit Solo 2 RTA is great for chain vaping although it does become a little warm. However being made mainly of Stainless Steel the tank does cool fairly quickly.

In the time I have been testing this RTA, I have had no leaking from it!

Pros

• Excellent quality and design
• Good flavour
• Smooth Airflow
• Great vapour production
• No leaks

Cons

I have no concerns with the function of this RTA!

Final Review Verdict

This is a standard-looking Hellvape tank, which fits right in with its predecessors.

It’s an easy-to-maintain RTA, and would be great for all levels of vapers!

I have been using the Hellvape Fat Rabbit Solo 2 RTA for a couple of weeks now. The only thing that is of slight concern is not being able to remove the bottom airflow ring without damaging the deck/base!
