While Wotofo may be a new name to you, they’re a vaping brand that’s been around for quite some time, since 2009 to be exact.

The brand have had some fairly big successes in the past, they’ve come out with reams of exceptional tanks, the Serpent range and the phenomenal Troll RTA not the least among them, also, their Serpent mod range and the Stentorian AT-7 box mod have received some incredible reviews.

The Wotofo Flow Tank

As for the Wotofo Flow Tank…even though it’s a lower wattage vape than I usually go for, 35-60W, I could not deny the flavour and superb vape quality on this sub-ohm tank.

As the name implies, the Flow is all about optimizing airflow and to me that means…flavour! But is as good as some of the best sub ohm tanks for flavour?

I can say from my side that I’m excited about checking out more products from them in future because the Flow tank showed me that, even if you’re a high wattage vaper, there are ways to make the most out of less than 60W…conserving that battery time and still enjoying a delicious vape with sweet clouds.

Build Quality & Design

On receipt of the luminous green and black, terribly shabby box (I’m a bit of a box hoarder, so I always like a neat box) I opened up to get a load of the first REDUCER I’ve ever seen…

Unaware that TDP efforts to “save people from e-liquid” had gone this far, I glanced at the strange silicon doohickey taking up half of my 4ml Flow tank’s juice space and wondered “WOTOFO is that thing in there!!!???”Wotofo Flow Airflow

Well guys, that thing is a reducer and it exists so that your tank can comply with unpleasant and unfounded TDP regulations. Long story short, that thing ain’t any good, so open up that tank, take that thing out and enjoy your tank the way it was designed to be enjoyed because luckily the silicon reducer is removable. Anyway, back to first impressions on the build.

The 24mm Flow tank (I got the black version) follows a simple, unadorned design, a thinnish base with very large, dual, adjustable airflow slots and a FLOW engraving, no knurling there but still quite easy to get a grip on, with just the right amount of give when to twist to make airflow adjustment no effort at all.

I see a very ample 4ml tank (which is still obstructed by that REDUCER in many of the photos I’ve included).

The top cap, which is equal in thickness to the base, is rounded at the upper edge and features circular indentations on the upper edge, an alternative to the usual knurling and it opens like a charm to reveal a standard top fill system.

The 510, removable Delrin Drip Tip is thickly cast and appears rounded, along with the rounded edges of the top cap, it makes for a good mouth and hand feel when the tank’s in use.

The 510 connection under the tank is silver plated and non-adjustable. I tested the tank out on the Captain PD270 from iJoy and the Smoant Charon, two of my faves, it fit perfectly on both. The 24 mm diameter makes it a good pairing for a good number of mod shapes and sizes.

Break down is incredibly easy, I must comment on the quality of the o-rings and the amount of give you get when you attempt to break the tank down, less trouble than it so often is, while still providing all the necessary seals.

The Included 0.25 Ohm Coil Heads

These single vertical coil heads, while advertised as 2.5 Ohm, both read as 0.3 Ohm heads on my mods and on my Ohm meter. That said, they exceeded the flavour and vapour production of many 0.2 ohm heads I’ve used, even when vaped at the lower wattages.

These coils are exceptional for this range of 35-60W and the wicking is great. In combination with this tank’s smooth airflow, they provide one of the best vape experiences I’ve had at low wattages between 35 and 60W, with far more flavour and vapour than I’m used to at those settings.

I forgive the fact that they read higher than they’re supposed to.


I was delighted to see a pack marked COMP WIRE inside the the box, however irrelevant to the tank. Unfortunately, that Comp Wire pack only contained seals, some of which were actually glued into the seal of the bag itself and quite difficult to extract in one piece, boohoo, no comp wire for me.

On the other hand, I was impressed by the inclusion of an extra coil head, complete with silicon cap for protection, very nice!

How Does The Wotofo Flow Tank Perform?

The airflow on the Wotofo Flow tank is something to write home about, providing an exceptionally smooth vape with my 80VG DIY liquids. Its utterly smooth and, when open, incredibly ample. A draw on open flow is marginally more effort than a breath of fresh air, only, this provided a mouthful of really rich flavour that I didn’t expect from these lower wattage coils.

I started the tank out at 35W and was taken aback by the substantial vapour production at this low wattage.

I then proceeded through the range, lingering on a room temp 40W for longer than I ever usually would, I was impressed by the depth of flavour and noticed some notes in my DIY flavour coming through that I’d never usually taste on such a low wattage coil.

I vaped the tank at 60W for some time, taking long draws in succession to see how the tank held up, almost no heating up and definitely one of the most flavoursome 60W vapes around. With huge cloud for this wattage, nice job!

One of the markers for me is the amount of condensation I see on the inside of the drip tip, I can tell this one is doing more work for its wattage than many other sub-tanks in this range.

The tank consumes juice a little quicker than your average under-60W vape, on account of its above average performance.

How To Fill The Wotofo Flow Tank

Very easy without the silly-con reducer, very difficult with it.

Simply screw off the top cap and fill down the side.

How To Change the Coil

  • Unscrew the glass from the base
  • Unscrew the coil head from its seat and replace
  • Screw on the glass and top cap section, watching that the central shaft screw into the coil head correctly.Coil for the Flow tank by Wotofo

What I Liked

The included coils perform well above average for this wattage range. I enjoyed the ease of breakdown and coil change, as well as refill. I also really favor this tank’s smooth and open airflow for an excellent flavourful vape.

What I Dislike

The coils didn’t read as 0.25 Ohm, as advertised, but I still enjoyed them.

Final Review Verdict

Even though the Wotofo Flow is a 35-60W tank, you’d swear it was 50-80, so rich and flavourful a vape does it provide, with smooth airflow and all round ease of use through utter simplicity. It’s a great option if you need to run a lower wattage mod with pleasure, you’ll save power but still get the flavour you want. Recommended for beginners and just about any vaper who’s looking to get the most out of less than 60W…this is a great flavour tank!


  • Solid performance throughout the range
  • Simple design for easy breakdown
  • Optimal, smooth airflow and excellent flavour and clouds


  • None

Greetings Vapers! I’m a 34 year old writer, editor and massive vaping enthusiast (since 2015) based in the beautiful Helderberg region in South Africa. My passion for vaping has steadily grown since I started vaping in earnest (as has my scorn for smoking). See, I tried vaping years before that but returned to cancer sticks after a bad experience (PG sensitivity). When I finally got back on the vaping train I decided to make it my business to educate beginners and vapers in general, so that they don’t jump to the conclusions that I did. I visualise a world without cigarettes…not just for health reasons: I’m tired of picking thousands of cigarette butts up off my lawn every morning, tossed over the wall by passers by. I can’t believe I used to be one of those people!
