Hellvape Fat Rabbit 2 RTA

Hellvape carry on their strong run with the Fat Rabbit 2 RTA

Share on:

Sourcemore sent the Hellvape Fat Rabbit 2 RTA for review. I like Sourcemore, I’ve been doing reviews for them on the POTV forum for about five years now and as long as you’re ok with a long wait for the different postal services to pass your parcel to each other, then you can’t go wrong. Any issues are ironed out quickly as well, so that's another plus for them there.

I also like Hellvape tanks. There was a trend a few years ago when I started vaping where all you would see on social media were Drag mods with the original Dead Rabbit RDAs on top. It did kind of put me off as I like to think I’m cool and don’t go with the crowd…spoiler…I am not cool, and I do go with the crowd, simply because sometimes the crowd is right. I absolutely adore the Fat Rabbit Solo RTA, it’s one of my favourites and I’m currently mourning the loss of my Dead Rabbit M tank, which escaped me on a recent night out.

The Hellvape Fat Rabbit 2 is a dual coil RTA with a dual airflow system and a postless deck. There are airflow rings at the top and the bottom so if you’re looking for clouds, then this is the RTA for you. As I have the international edition, this has a 4ml standard glass and a whopping 6.5ml bubble glass as well to make sure you’re not filling up every two minutes as it will drain your juice very quickly at high wattages. Luckily the TPD version seems to include the bubble glass as well. I find sometimes you get a separate box containing the bubble glass with Hellvape products when bought in the UK.

In the box you get:

  • 1 Fat Rabbit 2 RTA
  • 2 0.37Ω Ni80 Clapton Coil
  • 1 Bubble Glass Tube
  • 1 Coil Cutting Tool
  • 2 Shoelace Cotton
  • 1 Accessory Bag
  • 1 User Manual

Design wise, it’s a big’un, with a 28mm diameter so you’ll need a big mod for it to make sure there’s no overhang. It’s a tall boy as well, sitting at 48.7mm (drip tip included). Hellvape say the dual airflow gives three different configurations, and I could not figure that out for a while till I realised you can have the bottom open fully and top closed, the top open fully and bottom closed, or both fully open to give the three. In practice, I found a combo of the two airflow rings closed off to work best for me, but be careful, too little airflow in the bottom one with both open gives you a horrible whistle. I reckon dogs were covering their ears round my area when I tried that!  There is also a megaton of honeycomb airflow holes in both the deck, and on the chimney chamber to take the vapour away from the coil, past the airflow control rings, and right up into your lungs. 

The top comes off with a quarter turn to reveal nice big fill holes. You’ll be filling often, even with the 6.5ml bubble glass on, depending on what coils are put in the tank of course.  

I started off using the included 0.37ohm coils. It’s an easy tank to coil and wick, the included coil cutting guide helps but only goes up in 1mm increments so I used my coily branded one to get a 5.5mm leg length for both the coils. This meant the coils weren’t too far away from the honeycomb deck airflow and I felt they came up enough to catch the honeycomb airflow in the chamber as well, ensuring that I’d get a decent flavour. Wicking was also easy. Using the included cotton laces, I just cut flush to the edge of the tank and tucked the ends into the generous cotton wells once I’d laced them through.

I almost never use the included coils myself as I don’t feel they work as well as ones I have stashed away already. I was right. At 50W, these coils were not giving me much flavour, and when I pushed up to 60W, the vape was getting far too warm for my tastes, I like a relatively cool vape personally and I wasn’t going to be getting that and flavour with these coils in, so I ditched them to try a pair of self-wound Ni80 Alien coils. They didn’t work either, sigh. I’d not wound enough wraps and they were coming out at 0.09ohms so the Vaporesso Armour Max I use wouldn’t even fire them as it cuts off at 0.1ohms. Rather than faffing, I found some 0.3 ohm Ni80 fused clapton coils, popped them in and hoped for the best. Yessss, 0.12ohms! Can you tell I like Ni80 coils yet?

This was going to be a cloudy beast of a bunny, and it was. 50W did nothing, 60W,  nothing, 70W, and we were starting to cook up, but 80W is where I settled. It still gave a relatively cool vape, loads of clouds, and a quite decent flavour when I got my airflow preferences right. I could definitely have gone higher still with the wattage, but I’m a coward and am happy sitting with a coolish vape and nice flavour. In dual coil mode, you need to use a decent set of coils and you’ll get all the vapour you would ever want, and using the airflow rings, you can have it as airy or restricted as you want. I have found, however, that I prefer to have the top airflow a bit more restricted than the bottom. Call it bias, but I feel it gives a bit more flavour for me.

I decided against trying a single coil configuration as the tank just seems so well set up for big clouds with dual coils. It’s big, it’s airy, and I just don’t think it’d work well, even with a decent 4 or 4.5mm diameter coil. Plus the best I could do is an Ni80 Flapton, and I know these work well in single coil RTAs but on a dual coil? I’m not so sure, and I don’t want to ruin the experience I’ve had with this tank.

Final Thoughts

I know I’ve banged on about the dual airflow, but it really does work. If you want massive clouds at big wattages with big coils, then this RTA is definitely worth trying out because of the airiness of it. If you’re like me and prefer a more sedate vape then, as long as you’re willing to up the wattage a little more than usual, you’re also sorted, as the airflow can be configured to get a bit more flavour out of it while still getting a ton of vapour.  

Sourcemore currently have the Hellvape Fat Rabbit 2 RTA at under £25 when currencies are converted, and they’ve also provided a code for POTV that is SM8OFF and it can be used on most products that aren’t already discounted.

  • Clouds man, clouds
  • Good for big 21700 Mods
  • Once airflow is sorted, really good flavour
  • Needs decent coils to work it’s best

I was a very militant smoker for many years…why would I stop doing the only thing I had left that I liked doing?  Then I fell into vaping in 2017.  My wife bought a cheap kit off from Amazon that stopped working and I took it to a local vape shop to see what they could do with it.  An hour later and full of new knowledge about watts, ohms, and juice strength, I headed home with a new nautilus mini tank for her and raved to her about the helpful guy in the shop. I must have bored her with all my new found information.  I tried her vape that night, and a week later bought my own kit. Then I found POTV and the amazingly helpful and generous people on it. A month later I was making my own (disgusting) vape juice, and a month after that I was winding coils for my new RDA.  Six years on and I'm much better at making juice, and I now have no money but lots of shiny mods and tanks
