Hellvape Fat Rabbit Solo 2 rta
Hellvape_Fat_Rabbit_Solo_2_RTA.jpg
This time I bring something more interesting for rebuildable enthusiasts, a new rta. In this case, it's the Fat Rabbit Solo 2 rta, which can be used as a single coil, but the thing is that it can also be used as a dual coil. I don't know if that will be a pro or if it will be more focused on one than the other, but we will check it later, as the review progresses.

Thanks from here to Sourcemore for making this review possible. You can visit their website and learn more about the Fat Rabbit Solo 2.

Packaging

The RTA comes included in a rectangular box, where the first thing that catches the attention is the image of the product. In this specific case, I don't know if it's individual packaging or not. In the upper left corner, we find the product model, where the name is indicated. In the right corner, we see some branding, with the Hellvape flame logo. Just to the left of the image, the color of the product in question is indicated; as you can see, my edition is the Matte Full Black, which gives a very interesting effect when we add liquid, as it appears completely black.

On the back, some features are indicated, and on the other hand, something even more interesting, which is the contents of the box.

In the box;
1* Fat Rabbit Solo 2 RTA
1* Bubble Glass Tube
1* Shoelace Cotton
1* 0.37Ω Ni80 Clapton Coil
1* Coil Cutting Tool
1* Accessory Bag
1* User Manual

Apart from that, we can observe some warnings about use and vaping, as well as some logos, contact addresses, and a barcode for stores.

As soon as we open the box, we find an orange-colored pad where the RTA is supported. Even at first glance, we can observe a quality product with an aesthetic that, in my opinion, is very, very beautiful; look, for example, at the drip tip.

Just below the RTA, you can see the Bubble Glass Tube, which is an expansion of the tank and increases its capacity by 2mL, making it go from 3mL to 5mL. Although it's only a 2mL increase, it really makes a significant difference and is much more convenient. However, for some, it's simply quite ugly, and I can include myself in that group.

I present all the contents of the box in a single image, except for the User Manual, which I have not included.

On one side, we can find the RTA itself; again, I emphasize its aesthetic, it seems to me, along with the color, something truly beautiful. Right next to it, I present the Bubble Glass Tube, which we have already discussed before. In the lower part, I show you the Coil Cutting Tool, and on the other side, a small bag with o-rings, a flat-head screwdriver (which does not fit the deck screws), and some extra rubbers, in general, spare parts.

Atomizer Inspection

After completely disassembling the RTA, we have six distinct parts that I have grouped into pairs.

In the left group, we find the Top Cap and the Drip Tip. The Drip Tip is attached to the cap by pressure, as is usually the case, and it is also interchangeable with other 810 drip tips. The top cap has a specific position that we find by rotating it on the bell. This top cap must be removed to access the filling system.

In the central group, we find the bell and the upper airflow adjustment; again, this has a specific position that we find by rotating it on the bell. This will allow us to easily adjust the upper airflow.

On the right side, we find the deck, which implicitly has the lower airflow inlet and, of course, the 510 thread. Behind it, we can see the tank glass, in this case, the one that allows a capacity of 3mL.

Here I present the RTA deck, where we will place our coil and cotton. As I mentioned earlier, on this deck, we can mount both single and dual coils. This specific configuration is for a single coil.

To place the coil, we must unscrew two or four (depending on the configuration) flat-head screws. As I mentioned before, the screwdriver that comes included, at least for me, didn't work; it simply didn't engage the screw, so I had to grab another one.

In my opinion, it's somewhat complicated to properly adjust the cotton on this deck. From what I've concluded, it's very important to put plenty of cotton in the center of the coil and fluff the ends very well so that it can filter the liquid well and reach the center of the coil perfectly.

The ends of the cotton should be inserted into that small slot, let's call it that, which is obviously located on both sides of the deck.

I've had to do several tests because, I repeat, I find it somewhat difficult to get the hang of it. However, after several trials and errors, I can affirm that once it's well assembled, the flavor it provides is really very good and, thanks to the two air inlets, the vapor is also considerable.

The bell on the inside is like this; we can easily see the honeycomb-shaped airflow inlet; clearly, there is one on each side. As we can see, it narrows as its height increases, which attempts to enhance the flavor of the liquid when vaping.

A rather nice aesthetic detail is the fact that we can observe the rabbit on the bell, which, of course, is embossed on metal.

Here we find both air inlets; as you can observe, one is slightly offset from the other, which really bothers me in the aesthetic department.

Both work in the same way and can be rotated to fully open or fully close them. Thanks to this, we have three different airflow combinations. We can have both open, only the top one open, or only the bottom one open.

Personally, I've almost always been vaping with only the top one open, having the bottom one completely closed; for me, it was the best way both to avoid leaks in case of bad wicking and to achieve the best flavor.

I quite like the filling system; we simply unscrew the top cap, and we can observe two large openings, one on each side. Of course, we should never fill it through the center hole, only through the sides.

I really love this filling system; I find it really convenient and effective.

This is how the atomizer looks on a Pink Centaurus M100; it really looks impressive. I love its aesthetic, and it's not much larger than any other atomizer with commercial coils or RTA/RDTAs.

Vaping Time
I must say that I was not at all convinced by the coil that came in the packaging, so I simply threw it away, mounted a single handmade coil, wicked it with plenty of cotton, fluffed the tips a lot, and started vaping.

The flavor achieved with this RTA, if you manage to wick it effectively, is truly impressive, not to mention the vapor it produces and the crackling sounds the coil makes inside the bell.

Something that can be attractive to many people is the amount of air this RTA is capable of delivering to the coil; it's one of the airiest I've tried, apart from that 30mm atomizer from ThunderHead Creations.

As a negative point, in my opinion, the difficulty of wicking can be mentioned; it's quite complicated for someone who has just bought the product and may make them want to stop using it after a few days.

Conclusion
The Fat Rabbit Solo 2 RTA is an atomizer with the potential to offer a great vaping experience, especially in terms of flavor and vapor. However, the difficulty of wicking and some small aesthetic details can be an obstacle for some users. It is recommended for experienced vapers who are willing to invest time in mastering it.
