Hello and welcome back. I’m here with you today to take a look at the Hellvape Fat Rabbit rta Solo 2 that was sent to me by Hellvape in order to provide you with a fair and honest review. The Solo 2 has a 3ml capacity with the pre-installed straight glass and can accommodate 5ml when using the included spare bubble glass. The Solo 2 offers three airflow modes with honeycomb type airflow. It is advertised to support single and dual coil operation. We’ll have to see about that. The build deck is postless. It makes use of an included 810 resin drip tip. Often times these types of tips are too short for me but I’ll give it a fair chance.
WHAT’S 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
SPECIFICATIONS:
FEATURES:
1. 3 airflow modes for various taste experience
2. 2 interlayer honeycomb airflow
3. Supports single & dual coils
4. Postless building deck for excellent vapor
5. 25mm diameter, 810 resin drip tip
6. 3ml/5ml capacity, easy top filling
INITIAL THOUGHTS:
The packaging for the Fat Rabbit Solo 2 has the usual black and orange box. The front of the box has a nice color picture of the tank and a sticker indicating the color version contained inside. Of course the Hellvape name and logo are on the front as well as the name of the tank. The back side of the box has a list of features, contents list, and company information.
Once opened, the tank is exposed with the straight 3ml glass pre-installed and the spare bubble glass sitting below in the foam insert. The accessories included are located underneath. They include a single .37 ohm Ni80 Clapton coil, a single cotton thread, screwdriver, o rings, user manual, and coil cutting guide that has an arrow marked at the 5mm position.
Just like I do with any new tank, I disassembled the samples and gave them a hot soapy bath to eliminate any residual oil or impurites that might be left from the machining process. As you can see in the picture below, it comes with a nice swirled drip tip. The Solo 2 has both top and bottom airflow. Both rings can be removed and have a postitive stop. The build deck has four posts and even though it’s billed as a single coil rta. It is also advertised as being able to run dual coils but it is recommended not to go over 2.5mm when installing dual coils. I will give you my thoughts on this later in my conclusion.
The top and bottom airflow control rings have the same style of grooves cut into them for ease of adjustment. The top cap is a little thin but but has knurling on the outside edge to make it easier for the user to remove it for filling. There are two large fill ports that will accommodate any bottle. The o rings that seal the top are on the top cap. There is a small one on the center and a larger one around the outer edge of the top cap. The cap is removed with a ¼ turn.
The Solo 2 offers three different types of airflow. You can have just top, just bottom, or a combination of both and top and bottom airflow. It seems to me that the top airflow control introduces more airflow than the bottom control. At least that was my experience while testing the two. I ended up with the bottom slightly open and the top ¼ open for a slightly restricted RDL. This one can be as airy as you want with the combination of the two.
FINAL THOUGHTS:
Since I was sent two different samples, I decided to try the matte black version with the 3ml glass and the included .37 ohm Ni80 coil. My first attempt at building, I cut the coil to 5mm and centered the coil over the honeycomb airflow of the deck. I thinned the tails of the wick out a little too much and was the coil was getting over saturated but the deck was not flooding. I ran a couple tanks like that then rewicked the coil and left a little more cotton on the tails and got better performance. The flavor was very good and got huge amounts of vapor running the coil at 49 watts.
To test out the claim of the Solo 2 being able to be used with dual coils, I wound two 2.5mm Clapton coils with some 316SS 26/32 wire. This didn’t go very well for me. It took me three attempts at positioning the coils before they weren’t shorting out inside some reducing the resistance to .08 ohms. I finally did get them to work and came in at .23 ohms. I thinned the cotton wicks out quite a bit in order to get both tails into each hole. The flavor was good but I was getting quite a bit of spitting while trying to run them at around 55 watts. Any higher and it was just too warm for me with the amount of airflow that I like. I did open the bottom airflow some more than the black on this gold version. I also played around with the top airflow but I’m not a big fan of huge airflow. So for me, the Solo 2 will be used as a single coil rta which for me is where it excels.
I’d like to thank Hellvape for sending the Fat Rabbit Solo 2 RTA samples for my review. As usual it has been a pleasure. Hellvape makes some really good tanks that don’t break the bank which is great in my opinion. Also thanks to the readers for checking out my review.
