Hellvape offers its Fat Rabbit RTA atomizer in a Solo version.
Discover a single-coil atomizer with a spacious postless deck, compatible with different build types for an important vapor production.
This rebuildable has a diameter of 25mm, dual air intakes, an 810 drip tip, and two tanks of 4.5 or 5.5ml, according to the chosen configuration.

The smaller Fat Rabbit atomizer
The Hellvape’s Fat Rabbit RTA atomizer has the same main characteristics as the Fat Rabbit Solo RTA in a reduced format.
The main difference lies in the diameter. Indeed, the original Fat Rabbit is 28.4mm wide, whereas the Fat Rabbit Solo has a diameter of 25mm, compatible with most mods on the market. Note that its 510 connector pin also allows you to use it with mechanical mods.
The rest of the Fat Rabbit Solo atomizer has the same specifications as the other Fat Rabbits, which comprise a big 810 drip tip, the signature logo, and two air intakes.

The Solo’s single-coil postless deck
To access the atomizer’s postless deck, you have to close the lower air intakes first, and then turn the device’s lower part by a quarter.
The deck of the Fat Rabbit Solo RTA is smaller than the original Fat Rabbit’s. You’ll only be using single coils here.
The Solo’s deck has four slots for fitting your single coil builds the way you want to. There are also two wells on either side for putting your cotton into, and an airflow grid in the middle.
Finally, Hellvape includes a ready-made coil of 0.37 ohm and a cotton lace!

A dual airflow
Like its predecessor, the Fat Rabbit Solo RTA is equipped with a dual airflow system. The first intake is right beneath the deck, the second one is on the atomizer’s lower ring.
Thanks to these two air intakes, you can adjust and double the airflow for a cloudy vape.

An easy-to-fill tank of 4.5 or 5.5 ml!
Hellvape’s Fat Rabbit Solo RTA includes two different tanks in its kit.
The first one is a straight Pyrex tank of 4.5ml, which is already installed on the atomizer. The second one is a bubble-shaped Pyrex tank of 5.5ml.

The top filling system is handy and clean: turn the top cap with a quarter turn, choose one of the two holes, insert your bottle tip, and fill!
Warning: don't use the central hole, never fill to the brim, and wait for some minutes after the filling.
