Design and Build Quality
The Billow X RTA is very well presented in the box; it is made of stainless steel/pyrex and resin.
The Billow X dismantles into 5 parts for easy maintenance.
It has a 25mm base billowing (LOL) to a large 27mm diameter, with a 4 post staggered gold plated raised build deck, which is perfect electrical conductivity! Due to the way the posts are set out it makes installing coils very easy.
The internal airflow is raised and there are channels for your wicks in each corner of the deck.
The Billow X RTA has bottom cylon type airflow control, the branding on this tank is around the airflow ring Ehpro one side and Billow X the other.
On the base you have your normal CE marks, Ehpro branding as well as a gold plated 510 connection pin.
The Billow X comes preinstalled with a 4ml Pyrex glass tank; however the RTA is capable of extending to 5.5ml with the included Pyrex bubble glass tank.
The chimney and fill port are one piece, with threads for the top cap and threads to screw onto the build deck.The fill ports are wide kidney shaped holes the chimney section has O rings to hold the glass tank in position and to help stop leaks from the top cap.The decorations on the coil cover are a large X and what looks like billowing wind, these are kind of distracting for me and I cant help but feel the tank would have looked better without these.
Top Cap/810 driptip
The top cap screws easily onto the chimney section with the aid of knurling around its edges you have an O ring set inside of the cap for your.
The 810 goon style drip-tip is made of resin and has a beautiful funky marbling colour/pattern on it.
The Ehpro Billow X RTA is 45.3mm high without the 510 threading; all threads are smooth to operate, the design and quality of this tank looks to be very high indeed.
A basic how to guide
- Unscrew the base and install your coils and cotton.
- Dampen your cotton with e liquid and tuck the tails into the wick channels.
- Choose which tank option you wish to use 4ml or 5.5ml.
- Re assemble base into the main structure.
- Close your airflow!
- Remove your top cap to reveal the kidney shaped fill ports and fill with e liquid.
- Replace the cap, leave for a few minutes for the cotton to soak up more e liquid.
- Place on your desired mod and vape away.
*Tip Ensure you have enough cotton to fill the cotton channels well or you will experience leaking with this RTA.
The atty stands you can see in my photos are called Kizoku Magnetic, the stand cells are created by the Japanese designer Kizoku! They are available here in packs of 10 and come in different colours, a cool practical vape toy, made of plastic each cell has 8 magnets enabling you to form fun shapes with them.
How Does The Ehpro Billow X RTA Perform?
For this review I have filled the Billow X RTA with Obies Brew Coco Granola I also used 2 of the pre made Flat Clapton coils that came with the RTA they work out to be 0.16Ω after heating and strumming, I will be using the Billow X on my Wismec Reuleaux GEN3.
60W – 100w
Starting at 60W, 4ml tank, the airflow set to half using straight to lung style of vape, the vape was warm and pleasant with good flavour and a good amount of vapour production.
Bumping the wattage up to 80w and then to 100w with the airflow wide I found the heat of the vapour increased remarkably but the flavour, for me, diminished a lot. My sweet spot for this RTA is around 70w giving me a good balance between flavour and vapour.
With the airflow set just below ¼ open, I was able to get a ‘kind of’ mouth to lung draw from the Billow X, below this wattage the vapour was a little disappointing! This RTA likes power! The flavour was good though.
Filling & Leaking
The tank is very easy to fill due to the large kidney shaped fill holes, I always keep the airflow closed while filling. You need to use a lot of cotton in the channels or you will simply flood e-liquid when you open the airflow, trust me its happened quite a lot to me until I got the balance of cotton right.
Top Cap/Changing Coils/ Airflow
Care must be taken not to over tighten the top cap as it can be difficult to remove! While the cap has a type knurling I found more than once I had to use paper tissue to help me grip and remove.
Even if you have some e-liquid remaining in the tank changing coils/cotton is very easy just turn the tank upside down and unscrew the base, no e-liquid will escape unless you have a full tank!
The airflow is wide and swishy open to its fullest, although when seated on the mod I found it difficult, if not near impossible to alter the airflow due to airflow ring being recessed to the larger tank. You simply cannot get purchase on the airflow ring without unscrewing the tank, I ended up removing the tank from the mod every time I wanted to change the A/F, also I find the airflow set to half and lower tends to be quite noisy!
As always part of my tests include Chain Vaping, the tank held up well to this test at 60W however it did get very hot and didn’t cool very quickly, the 4ml tank empty’s quite fast as well while chain vaping, so no big surprise there LOL.
- Being able to change the 4ml glass for 5.5ml bubble glass
- Good flavour and vapour production from 60W
- Fair design
- Good quality of build
- Bonus for me is the resin driptip
- Noisy airflow
- Recessed airflow ring
- Leaking issues if not enough cotton used
Final Review Verdict
I have never owned any product by Ehpro before, so the Billow X RTA was a personal learning experience for me, after I learnt the correct way to wick this beast, through trial and error I might add, which truth be told I did almost gave up on it, due to the air being so blue cos of its constant leaking!
I’m glad I didn’t give up as I’m truly impressed with the Ehpro Billow X RTA and the flavour I get, although the airflow ring is right royal pain in the butt I enjoyed using this RTA.
Would I buy the Ehpro Billow X RTA again should I damage or lose it? Yes I would.
