Wotofo Profile X RTA

Wotofo Profile X RTA Review – Phenomenal Flavour!

Rebuildables are not coming out as thick and fast as they used to, and so when one does come out, we do try to get our hands on them when we can! And so, today, we shall be looking at Wotofo’s latest addition to their DIY atomiser line: the Profile X RTA!

This device was kindly sent to me for review purposes by Wotofo, with my kind thanks to them for giving me the opportunity to share my feedback with vapers all around the world!

The Wotofo Profile line of atomisers has proven to be very popular within the vaping community. It is not an uncommon story to hear that one’s first rebuildable atomizer of the last 3 years or so was the Profile RDA, and this is very understandable due to its simple build requirements and amazing flavour.

Since the first Profile RDA, several RDAs and RTAs within the series have followed suit, with the Profile X RTA as the latest. Not to be dismissed as “another series update” though, the Profile X RTA does come with innovative engineering worth paying attention to!

Without further ado, let’s get on it! As always, my review will be from my own personal experience as an average vaper, as most of you reading will be.

Packaging and Contents

I was sent the retail version of the Wotofo Profile X RTA, containing a heck of a lot of gubbins!

  • The Profile X RTA boasts a 5 mL capacity with the straight PCTG tube.
  • A bubble glass, expanding capacity to 8 mL.
  • 2 x 0.33 ohm Ni80 Framed Staple Clapton Coils. Always love it when manufacturers state the coil material!
  • 1 x 0.15 ohm nexMESH Chill A1 strip.
  • 1 x 0.16 ohm nexMESH Extreme A1 strip.
  • 1 x 0.13 nexMESH Turbo A1 strip.
  • 2 x 3 mm shoelace cotton strips for the wire coils.
  • 3 x 6 mm cotton strips for the mesh coils.
  • Mesh bending tool.
  • A user manual.
  • Accessories including o-rings and building tools.

Wotofo Profile X RTA Box Contents

The RTA comes in Wotofo’s signature black and green box lathered up in big and bold branding. A plastic top makes the RTA and bubble glass visible, and these sit inside a compartmentalised foam tray, with the rest of the RTA’s accessories packed underneath. Printed on the box are the contents, manufacturer information, and standard warning.

Salient Features include:

  • A base diameter of 28 mm, and this width will be a few mm more when the bubble glass is used. Keep this in mind when matching with your mods if you don’t want to see an overhang.
  • A height of 44 mm, which actually isn’t tall compared to some RTAs in the market.
  • This is probably the selling point for me: a build deck that actually does cater for both mesh and wired builds (more on this in a bit).
  • Top airflow and top fill.
  • A slight turn unscrews and reinstalls the top cap for filling.

Aesthetics and Ergonomics

The Profile X RTA is an unmistakable Wotofo Product, with obvious branding on the airflow control ring, chamber, and underside of the base. In the Black finish I received, I actually like the somewhat matte finish Wotofo used- I think it goes very well with the RTA’s short and stubby look.

Wotofo Profile X RTA PartsAll parts are exceptionally machined with no crunchy threads of sharp parts. The RTA also dissembles easily for cleaning (yes, even the bubble glass) which is always a pro. The top cap and base have angled cutouts for effective grip.

With the RTA being made of mostly metal, it does have a slight but nice weight to it. The stock 810 drip tip has a resin design and is quite on the short side. Normally, I’m not a huge fan of short 810 drip tips as they tend to be too hot for me, but the Profile X RTA’s drip tip matches the atomiser perfectly and adds just the right height. This is because the top cap does have an outwards lip that “lifts” the drip tip from the top cap. The drip tip was also very comfortable to use; and yes, was not hot at all for me!

Wotofo Profile X ChamberThe big, kidney-shaped fill holes are quite recessed inside, which is the first time I’ve seen this design in an atomiser. At first, I thought it was just a style choice but it’s actually a functional change that Wotofo made here. See, with the fill holes being so recessed, it allows for the chamber to be narrow to help with airflow and flavour (more about this later too). Needless to say, I’ve had no problems whatsoever with refilling with any e-liquid bottle, due to the large fill holes.

Now we get to the airflow. Top airflow atomisers can be hit or miss in general, but Wotofo really hit the nail on the head here with the engineering they employed on the Profile X RTA. A traditional metal ring with 18 holes on each side and with full stops effectively controls the airflow. Fully open, it is quite airy and so I found myself closing down 4 holes at each side for the draw I like. Being generous with airflow, cloud chasers should be happy with this RTA!

Wotofo Profile X Middle

Going back to what I mentioned earlier about the narrowed chamber, this is really important to make the airflow work well. Air comes from up top and onto the coils, and with the narrowed chamber, has little distance to travel to the mouthpiece. This helps the RTA to give maximum flavour! And, being a top airflow RTA, that does mean no possible leaks to worry about!

Wotofo Profile X RTA Part


And coming to the star of the show: the build deck! Being a 28mm deck, there is plenty of room to manoeuvre when building. The wicking wells are also generously-sized as a result, which bodes well for ease of wicking.

Wotofo Profile X RTA Empty DeckThe centre of the build deck is where Wotofo’s innovation really comes through. Because, unlike the Profile M RTA (for example) that is billed to accommodate both mesh and wired coils but has a typical mesh build deck, the Profile X RTA is upgraded to have dedicated coil lead slots for wired coils! This is accomplished by having a couple of elongated slots cutting through the ceramic block, which is positioned over 4 lead trap slots, perfect for a dual coil configuration. Imagine a post-less design RDA or RTA- that is basically what you get with the Profile X RTA, just with the ceramic block sitting on a spring over it.

This is, I think, a major statement of intent from Wotofo because although mesh build decks can be used with wire coils, doing so can be quite clunky and tricky, especially in a dual coil. Now, with dedicated slots for the leads, you wouldn’t have to clamp coil leads, and these clamps will just be for the mesh strips only. Is that cool or what?!

Having said all this, and to provide you with a different perspective of using the Profile X RTA (versus other reviews of this RTA you might find in the interweb), for this review I have decided to focus on building using a dual coil configuration!

It’s simple enough, although applying great care is always advised!

  • To build with dual coils, you’d need to remove the mesh clamps to access the post screws. I’d also advise removing the ceramic block to allow more space for your coils.
  • For this build, I used the 2 x 0.33 ohm Framed Staple Clapton coils that came with the kit, which have a 3 mm ID. I wouldn’t advise using coils wider than 3 mm, in fact, a 2.5 mm ID pair of coils may be more comfortable to use and would be advisable for beginners.
  • Unscrew the post screws.
  • Trim the coil leads so that, when installed, the bottom of each coil would be at least 1-2 mm above the raised metal parts on the side (with 3 mm ID coils). I wouldn’t advise going any higher than that though, or else you risk shorting as the coils might touch the chamber dome.
  • Install the coils with one lead of each on the positive side.
  • Position the coils so that the coils are not touching each other or the raised metal parts on either side. With 3 mm ID coils, this can be quite tricky and so I would advise doing this step carefully. As a pro tip, once this step is completed, screw the deck back into the chamber and then reinstall it onto your mod. If your mod still reads the right resistance when firing, then you’re good to go!

Wotofo Profile X RTA Coiled Deck

  • Pulse the coils to get rid of hot spots and any oils. By the way, you will notice that I spaced my coils, but that is just out of preference.
  • Wick each coil, with the ends trimmed right to the edge of the base.
  • Thin the cotton out a little, and tuck inside the wicking wells in such a way that the wick ends are just above the deck base.

Wotofo Profile X RTA Wicked Deck

  • Prime your coils, reassemble the RTA, fill, and enjoy!

With this dual coil build, the Profile X RTA provided me with the best flavour experience I’ve had with a top airflow RTA! I’d rate it at 9/10, which is pretty darn good for non-RDA atomisers. The short form factor plus the engineering choices Wotofo made with the narrow and condensed chamber made for great flavour, and for any of the e-liquids I tried with it.

The build above ohmed out at 0.26, which I vaped at around 55W. The airflow is smooth and quiet enough, and really, I can’t complain about the vape quality of this RTA.

Overall: Yay or Nay?

Unequivocally, a Yay from me for the Wotofo Profile X RTA! Although the dual coil build was a little finicky, it’s worth the extra steps in the end for the phenomenal flavour this RTA churned out!

Along with its amazing flavour, it is easy to use and maintain and is leak free. I highly recommend this RTA for experienced builders looking for RDA-like flavour in an RTA! For beginners, it is also a good choice especially in its mesh set-up, plus the fact that this RTA offers variety in the builds that can be installed in it.

And yes, I did test the RTA in mesh mode as well, and as expected, it provided me with the same amazing flavour, with a far easier build experience (as is expected with mesh!).
