Review: Fat Rabbit 2 RTA – Hellvape

The Fat Rabbit 2 RTA by Hellvape is a dual-coil, 28 mm diameter atomizer. Thanks to its double airflow system, it makes high-quality vapour across a fairly wide power range. It is a particularly effective, reasonably priced atomizer.


Just another Rabbit?

Although the Hellvape collection is huge with all of its Fat Rabbit and Dead Rabbit models, it’s clear that not all of their offerings have meet our expectations as vapers. That said, the Fat Rabbit 2 RTA is bringing some kudos back to the brand. Despite its huge airflow system, it is still a well-balanced atomizer.

A simple but effective design

The design of the Fat Rabbit 2 RTA is simple. With its straight 4 ml tank, its look is understated. It also has one airflow inlet at the top and another at the bottom of the atomizer. It can take big assemblies and high power levels without a risk of overheating and still feel very airy. But the best thing about the Fat Rabbit 2 RTA is the quality of its flavours, no matter what set-up you use. We will come back to that later.

Both the top and bottom airflows are easy to turn. They let you vary your vape from a fairly airy one to a more restricted, hotter one. However you use it, the atomizer is only designed for DL use. The narrow knurling on the top cap just above the airflow ring makes it easier to access the filling holes.

There are 2 large holes, making filling easy. You can use any bottle tip size. If any liquid spills, the top will catch it and channel it into the openings. The whole operation is so simple. Just unscrew the top cap a quarter turn to fill your atomizer.

Inside the atomisation chamber there are 2 lines of holes that let air into the coils. You can feel the effects of this set-up when you use the top airflow by itself or in combination with the bottom airflow. You can’t remove the part on the inside during cleaning though.

Big vapour, big flavours

The dual-coil mounting deck is postless. There are plenty of holes right next to the coils for effective cooling when the bottom airflow is in use. The machining is perfect and the solid metal feels reliable.

There are two channels on each side of the deck to guide the wick and hold it in place, making it easier to close the dome. The channels are a bit narrow, but they’re big enough to make sure the wick is always perfectly moist. Make sure you don’t put in too much wick or you might get a dry hit, and check it’s sitting properly in the channels. Even so, the Fat Rabbit 2 RTA isn’t fussy about how well you insert the wick, so you don’t need to be overly careful. It would suit any beginner who’s just getting into rebuildables.

Fitting the coils is equally simple, with a cutting guide for the coil tabs in the box. You can choose whether to mount the coils more or less centrally on the mounting plate. The Fat Rabbit 2 RTA works just as well with high-powered, exotic coils. When we tested it, we got good results between 80 W and 120 W without the atomizer overheating.
So yes, it is another Rabbit. But we have to admit, this one is really good. Whether you choose to open just the top or the bottom airflow, or both at the same time, it delivers great flavorsflavours. This atomizer never gets too airy and works well at higher power ranges. That guarantees good flavours and excellent cooling for the assembly.

Self-taught and curious by nature, I developed my journalistic skills in the field by joining the Vaping Post in 2017. As a former smoker who converted to vaping, I immediately felt the need to understand in detail all aspects of this smoking risk reduction method that has enabled me to successfully quit smoking where previous methods had failed.
review-fat-rabbit-2-rta-hellvapeThe Fat Rabbit 2 RTA is a pleasant surprise among Hellvape’s more recent offerings. It’s easy to use, well designed, and delivers great flavours for such an airy vape. It’s easy to assemble, even for a beginner. The atomizer can also handle high power levels.
