Fogger V2 RBA Review


With Pyrex RSST and my Smok eGo lost, I figured to try a Kayfun style RBA for its efficiency, general lack of leaks and lack of wasteful condensation.




Nice amount of extras including a fill screw screwdriver, and even 2 spare wicks and wires- 1 SS mesh and 1 Silica. The wire I’ll guess is nichrome 30-32g.



Interestingly enough it comes pre-built, albeit rather poorly given the design and its common out-of-box flaws like relatively poor wicking and/or leaking into and through the air hole.


It does light up nicely though.

So, my guess is that my initial fill caused a pressure-leak and from there I decided to go ahead and mini-overhaul and build it all up. As per suggestions, I added one small silicone O-ring to the bottom contact screw to prevent it ever touching the sides of its well and shorting everything out. Next came drying it all up and looking at the air control assembly, which was indeed quite a pain to unscrew initially. Had to use 2 lockable gripped pliers to even make it budge, but after the initial struggle everything came apart nicely.

Everything on the inside looked fine to me, so I went ahead and jammed another small O-ring around the positive post to make sure it would never touch the well. This should also help prevent any juice from leaking too far into the post’s well. After all that, bottom deck reassembly and testing to make sure the air holes didn’t get blocked while twisting it back together, I went ahead and built the coil.

Here I used my 2.5mm Ekowool with cotton center threads and 6 wraps of 28g nichrome that yielded 1.3 ohm resistance post-to-post.


And it produced pretty decent vapor.


Here I juiced the wick, tucked it inside as best I could and left a tiny little nubs in the bottoms of the juice slots and screwed the chimney on without the provided silicone O-ring. Put the tank on, opened the fill screw, and filled with syringe tip juice bottle using this method: fill with the air control completely closed down and holding the chimney hole with a finger, then screw the fill screw back on, flip everything upside down, open up the air control, and finally let go of the chimney opening.

No leaking now, and pretty solid juice flow thanks to the crazy ekowool.

Now it vapes very nicely and I suppose only time will tell whether or not it will leak again.

Fogger is pretty fun given that its small chamber wastes nothing and delivers pure flavor right off the bat. I can’t think of too much condensation building up and simply wasting away given its design, unlike the RSST.

Juice I got along with this guy is Jasmin Aloha e Juice from Eciggity, and it is very smooth and light. Tastes just like jasmine and that does the trick for me.

Last few words- I would recommend Kayfun style/Fogger RBAs to experienced builders only since making coils for this thing is a very delicate and precise process. You definitely get your effort’s worth, but its nowhere near as easy as Genesis styles like RSST.


Post day-and-a-half of vaping this thing, I can safely say that it IS very, very solid. After a new tank refill it worked just the same and didn’t even attempt to leak. So far, very solid as I have anticipated it to be.

Another thing I’d like to add is that from looking at the Kayfun Lite/Russian 91% designs and concepts, I prefer this more simple wicking method.


Smoktech DCT

Got a bottom-fed, cartomizer style dual coil tank to try out this whole vaping direction, and while a completely different feel from wick-fed tanks, I gotta say that I like this a little bit better on the go.



The DCT sports replaceable single or dual coil atomizer barrel that slide inside a 3.5 or a 5ml tanks and use standard 510 drip tips. While the whole rig is pretty much held together via silicone O rings, it surprisingly stays intact quite well.

filling the tank, especially 3.5ml, can be a little bit delicate since you have to avoid dripping into the metal barrel. With some care, it’s not too bad to get these to 75% full and that can last (me) 2 days if not a bit more (with the 3.5ml tank).

The burning of the dual coil produces far thinner and lighter taste, thus I can tug on it much longer than on my RCT. The real advantage is that the juice hole is at the very bottom of the tank, so DCT will not run dry until all of the juice is used up unlike the RCT whose wicks start having trouble routing the juice when the tank gets to 15-10% full. Avoiding dry hits is easier with these as well- a couple deep, blank pulls will get enough juice into the atomizer and it’s ready to go again and again.

Overall, nice system that is still affordable and rebuildable.

Smoktech RCT – Air Hole Patch

So I noticed that RCT tank has the same air hole down at the bottom of the battery connector like most other 510 tanks and carts for auto battery’s sake. Now that I’m on the eGo, this serves little to no purpose for me, but it does leak a tiny bit. Though this leak doesn’t interfere with the current passing through, it does corrode the threads of the tank’s connector and just annoys me enough to try and plug it.

And I did so via a small circle of aluminum tape.


This displaced the 2 little air holes a tiny bit and blocked off the main one, so the draw is a bit harder, but it seems to conduct better without that drop of liquid being in between contacts and there’s definitely no more corrosion going on.

Little Big Revamp – Smoktech RCT and Joye Ego

So I’ve been neglecting my poor little e-cig kit for a while, and thus decided to do a little overhaul.

Through some net search I came across MadVapes and saw a very attractive deal in their sales section:


Smoktech Replaceable Coil Tank (RCT) for only $4.29. It could use the Joye 510 batteries I had a few of already, so I figured it would be worth a try. Once I got it (the yellow one), I loved how fresh and powerful it was compared to the old little 510T atomizer, so I figured a proper overall upgrade was in order (as well as a spare RCT just in case- purple one).

I went back to Madvapes and ordered a spare tank, some RY4 liquid for a change (VS Banana has been getting old, but when you have ~60/120ml left, you’re just not as inclined to buy any liquid at all), and the real star of the show- Joye eGo 900mAh battery with a usb pass-through mod by Smoktech.


Tank can hold 5ml of liquid!

Before I drown this with words, here are some more shots of this thing plus comparisons with 510T:



*On the vaping note, it seems that you have to fill this tank at least half way to properly submerge the wicks to avoid getting dry pulls. I’ve been playing with 1/5-1/4th full and longer draws were ending a bit dry.

So why eGo battery despite owning 3 510XL ones? Well, predominantly for the USB pass through feature that lets you charge via mini-b cable AND use it while charging. Battery capacity is nice to have as well, since my skinnies are 280mAh for manual and 340mAh for one automatic, so the new 900 is like the 3 combined. Ability to use USB port eliminates having to carry a special and slow proprietary charger.


Lastly, I believe my eGo does not have an automatic cut-off per continuous use like some do or I simply couldn’t hit my liquid for that long since it is very harsh, but that’s the way I like it!

Lastly I’d like to cover how nice the RCT’s build quality is. It is fully rebuildable as you can see in the very first image, but that’s not all. The end caps screw into aluminum thread instead of inside or outside the polycarbonate tank, so opening and closing it will have little to no wear and tear. Then, every part that can be removed has a silicone O-ring to properly seal it and keep the liquid from leaking out. Very nice touch!


Lastly here’s a lil shot of the coil:


All in all, very happy with this purchase and the fact that whenever (if ever, haha) it burns out, I can simply replace the whick-and-coil piece and not the whole thing. The tank size could’ve been a bit smaller IMO, but beggars aren’t choosers. The over-sized tank might possibly protect the battery button from being pressed when carrying this thing in pants pockets.
