We had an overwhelming number of requests from our fellow vapers and so we made it happen. We bring you the Billow v2 Nano RTA! All of the features are identical to the Billow v2 RTA except its shorter and holds 3.2ml of e-liquid. The glass section still tapers out measuring 23mm in diameter and the base and the top cap of the Billow v2 Nano RTA are still 22mm in diameter allowing it to still sit flush on all of your 22mm mods!


  • New barrel and groove exterior design with two piece chimney
  • Rebuild and make adjustments to your wick and coils without dumping out your juice
  • Deck is designed with cotton grooves for convenient wick placement
  • No more screws to fill juice or adjust airflow
  • Adjustable Airflow Ring
  • Peek Insulator for low sub-ohm durability
  • Bigger Airflow Hole on the Airflow Ring and Deck
  • Wide Bore Delrin Base Drip Tip
  • 3.2ml Capacity

Note: The Airflow Ring's resistance (how easily it turns) can be adjusted to your liking by slightly screwing in or screwing out the small screw under the Airflow Ring.

Coil Recommendation: We recommend building 2.5mm or smaller diameter coils for the Billow v2 Nano RTA.

Replacement Glass is available here:

The Stainless Steel Section for the Billow v2 Nano can be purchased here:

    Too compact

    Posted by JACK M on May 24, 2020

    The build deck is tiny, and I cant get it to not leak through the air slots. When it works, it does put out some pretty good flavor. All in all I believe it's just too much packaged into such a small space.

    Billow V2 nano

    Posted by Fishaddict on May 10, 2020

    This tank is fantastic, plain and simple. Got the wicking right first try, running 27g SS coils and the flavor is on par with some of my rda’s. About to order a second.

    nice tank bad deck

    Posted by Gerald Craig on Feb 03, 2018

    the tank it self is fine but the deck is a nightmere to build , tried several builds and just could not get past the way the post holes are staggered poorly thought out deck , I ended up just throwing it in the trash a complete waste of money

    poor build deck, waste of money

    Posted by Gerald C on Jan 29, 2018

    I tried 3 sets of micro coils problem with this is the build deck is made in such a way that when you get your coils in , they do not line up under the air holes , They need to rethink the build deck BIGTIME. I just thew this in the trash

    Billow v2 Nano RTA

    Posted by John on May 03, 2017

    I lost my regular sized Billow V2 and wanted the smaller "Nano" version. Absolutely love'em both. They are simple in design, don't leak, easy to build on, and fit perfectly on my SMPL mechanical mods, which IMO is the best setup because its a small package and works every time with no mess & no issues ever (2+years until I lost it). Got the v2 Nano Stainless Steel Sleeve to replace the glass one whenever I drop this beast.

    Always a good tank

    Posted by Andrew on Nov 03, 2016

    Billow'so have always been good. No matter how they change them they always hold that smooth airflow and a thick juicy hit we all love. Hits just like a billow v2 does with a smaller package. Colors are nice too.

    Excellent for thick juice

    Posted by Rick on Jul 21, 2016

    This is my first RTA. Before this, I was using an Aspire Nautilus, and it was a nice little lung-to-mouth tank, but this thing blows it out of the water. I use max vg or 100%vg base juices, which are very thick, but this tank wicks like a madman. So far, the only dry hits I've had are from chain vaping some of the thickest juice I had for several minutes, which kind of gave me a headache. I don't normally vape this way, but I wanted to see what the Billow's limits were. It turns out they are much higher than I need them to be. I don't run my mod too hot; I'm using a Coolfire IV, currently set to 33 watts with .6ohm coils, so YMMV. I have had 0 leaks after I got the wicks set into the tops of the juice channels properly, even carrying it around in my pocket. I don't have any previous experience with RTA's, but I bought this after finding several recommendations for max vg users online, and it works as well as the most glowing reviews said it would. I'll be buying one or two more in the future, so I can keep a few flavors on standby. Building wasn't too hard, thanks to an online tutorial by The Modified Vaper (highly recommended--the guy's a trip). This unit is easily worth every cent I paid.

    Nice tank at a great price

    Posted by Steve Thompson on Jul 12, 2016

    I have been really enjoying this one, works great and fits my Tesla Stealth great. Really easy to build and top notch quality. If I have a thumbs down it would be that the blue color is not a match for any or my blue mods, other than that I recommend the Billow 2 Nano to anyone looking for a good quality RTA.
