Billow RTA V2 – An Improvement On The Original?
Eciggity and EHPRO have listened to the feedback from original purchasers of the Billow V1 Rebuildable Tank Atomiser and come up with the Billow V2 which promises to offer a Rebuildable Dripping Atomiser level experience in a RTA, and resolve the issues reported with the original Billow RTA.
This time around Eciggity and EHPRO have shortened the chimney section whilst retaining the 5ml capacity, removed the airflow screws and bottom fill screw, added an adjustable airflow control ring, enabled you to get at the build deck without dumping your juice out and you can bottom fill without the need for a bottom fill screw, amongst other little tweaks. Sounds really promising!
I was a big fan of the original Billow RTA, and felt that it was a great RTA that provided almost RDA level flavour and clouds, but let itself down with leaking problems and the fiddly airflow screws. Does the Billow V2 solve this original issues and finally bridge the gap between RTA and RDA?
Billow RTA V2 Kit Contents
- Billow V2 RTA
- Delrin and Stainless Steel drip tip
- O-Rings, muji cotton wick, two 0.5mm kanthal premade coils with a 2.5mm internal diameter
As per with the Billow V1, Eciggity and EHPRO have gone all out with the kit contents for the Billow V2. The packaging itself is very much the same as the V1, with the tank picture and text updated to Billow V2, and inside you have the same excellent flat and cross head screwdriver keyring tool along with everything inside to get you going.
Billow V2 RTA Set Up
It’s just as easy to set up and get going as the Billow V2 was, the top tank section comes apart from the base easily revealing your build deck. This time around there are a couple of small improvements to the deck- the cyclops airflow slots have been widened and centred for even better flavour results, and the huge juice channels are now T-shaped at the top to provide a small ledge for your wick to sit on which increases the amount of juice soaked up and reduces the possibility of dry hits.
The deck itself has actually been made slightly smaller than the Billow V1 as with the chimney size to increase flavour, you don’t want to be building coils larger than 2.5mm in diameter.
What has remained the same is that the same PEEK insulators are used so super sub ohm builds can be handled without the tank getting too hot, it is dual coil only, you have a four post configuration with generous post holes to build with and the Phillips head post screws are smooth and easy to screw in and out.
Again, the deck is also clean and free of machine oil. The wide bore drip tip supplied now has a delrin base to stop it from getting hot when the Billow V2 is used at high power, the exterior of the drip tip is still Stainless Steel so a bit of a drip tip gunk magnet!
For my build this time, I used the included pre made coils that came with the Billow V2 package, these are made from 0.5mm kanthal and have an internal diameter of 2.5mm. These read at 0.22ohm upon installation however after a quick dry burn and centering the coils the resistance came out at 0.25ohm.
I made sure these lined up over the airflow slots on the deck to make sure I was getting the best flavour possible from this tank. Juice channels are still massive as per the Billow V1 and more than capable of handling high VG, this time around however is that there is a small groove cut into the deck at the top of each juice channel for your wick tail to sit in and soak up juice.
This seems to work perfectly as whenever the ends of the wick tails sit in here I do not seem to get dry hits, even when chain vaping at high power, I trialled putting wick further down past these grooves into the juice channel but this gave me dry hits.
The ability to get to your deck without dumping out all of your juice from the tank is brilliant- I had an instance when I re-wicked, filled up a tank and started getting a couple of dry hits after about 10 or so draws- I simply unscrewed the tank section from the base and sat it on the side upside down, saw that some of the cotton had slipped down into the juice channel so pushed it back up onto the wick groove, screwed everything back together and vaped straight away and no more dry hit issues.
All of this without needing to waste a full tank of precious juice! Filling the tank is done by unscrewing the tank section from the base and pouring juice to the side of the chimney, no more fiddly fill screws, and this works really well.
Another massive addition made is that the airflow screws have been done away with and an airflow control ring is now found on the side along with two cyclops airflow slits. At first, this seems pretty loose, but you can adjust the resistance of this by adjusting the small screw found under the airflow ring. I gave this a couple of small turns to tighten it up slightly as I found the airflow control ring to be too light out of of the box.
Overall, I found the Billow V2 much easier to set up than the Billow V1.

How Does The Billow V2 Perform?
The original Billow V1 I loved despite the leaking issues because of its superb performance. The Billow V2 has improved on this greatly and best of all- no more leaks! I believe that the redesign allowing you to fill the tank with no fill screw needed and the ability to get at your deck has improved this greatly, along with reducing the size of the build deck.
I have had the Billow V2 laid on its side for a number of hours and try as I might the Billow V2 just has not leaked on me at all.
Reducing the size of the build deck and the chimney has really improved the flavour on the Billow V2, the original had great flavour but the V2 can definitely compete with RDA’s in terms of flavour. I can have no complaints about how good the flavour is, my juices tasted pretty much as good as they did in a lot of my RDA’s.
Cloud performance is just a touch better than on the V1, which already provided superb clouds, cloud production is dense and thick, with the more power you can put through this tank the more vapour is produced.
It handled up to 100w with no problem- and the upgraded juice channels meant that the Billow V2 wicks juice superbly at any power and juice mix used. Airflow control ring is a vast improvement on the old style screws used in the V1.
It is definitely one of the absolute top performing tanks available! Absolute top marks for performance.
The Billow V1 was so close to being the total package, but let down by a few small issues. The Billow V2 is the total package this time around! The bridge between RDA’s and RTA’s had been near enough closed with the Billow V2, which provides RDA level clouds and performance, a leak free design and the ability to get at your deck without losing a whole tank of juice is arguably the best addition to the Billow V2.
The Billow V2 feels like a totally brand new design, it’s been totally redone and as a result can proudly call itself a flavour and cloud machine!
It’s become my favourite rebuildable tank, and comes highly recommended from me! It is truly an amazing bit of kit.
